New ASME A17.3 2011 Edition released: Safety Code for Existing Elevators and Escalators (Includes Requirements for Electric and Hydraulic Elevators and Escalators)

The new 2011 Edition of ASME A17.3, “Safety Code for Existing Elevators and Escalators (Includes Requirements for Electric and Hydraulic Elevators and Escalators),” has just been released.  The new 116 page code establishes minimum requirements to provide a reasonable degree of safety for the general public.  It is intended for anyone engaged in the safety of elevators, escalators and related conveyances.

A17.3 is intended to serve as the basis for state and local jurisdictional authorities in adopting retroactive requirements for existing elevators and escalators to enhance the safety of the general public.  It is also intended as a standard reference of safety requirements for the guidance of architects, engineers, insurance companies, manufacturers, and contractors, and as a standard of safety practices for building owners and managers of structures where existing elevator equipment covered in the scope of the Code is used.

ASME A17.3 guides all parties engaged in the safe installation, inspection, testing, operation, and/or insurance of existing elevators and escalators.  As an alternative standard to A17.1, it also allows for more flexibility in problem-solving.

This is the fourth A17 standard released in recent months.  The others are ASME A17.1, “Safety Code for Elevators and Escalators,” ASME A17.2, “Guide for Inspection of Elevators, Escalators, and Moving Walks,” and ASME A17.5, “Elevator and Escalator Electrical Equipment.”  The standards should be stable until the next revision cycle in about 2014.

All ASME Standards, including obsolete editions, can be purchased from Document Center Inc. through our website, www.document-center.com.  Or contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We’re happy to assist you with any standards questions you may have.

New Revision A released for MIL-STD-38784 on Technical Manuals: General Style and Format Requirements

The new Revision A for MIL STD 38784, “Manuals, Technical: General Style and Format Requirements,” was released on 8/25/2011.  The 140 page standard replaces the 1995 Edition with Notices 1 and 2 from 2000.

This standard covers the general style and format requirements for the preparation of standard Technical Manuals (TM) and for such changes as are intended for military applications. This includes all technical documents assigned a TM identification number and controlled by a TM management information system, or subject to requisition from an inventory control point.

MIL-STD-38784 provides for Standard Generalized Markup Language (SGML) Document Type Definition (DTD) usage (see Appendices B through E) required for electronic data delivery, including PDF. This standard supplements the performance of detail specifications used for specific TM types and related publications, but does not deliver any technical data.

The examples provided at the end of this standard are typical and may be adapted to fit the specific equipment or situation being covered unless otherwise noted. All appendices are intended for compliance when applicable.

Technical publications prepared in accordance with this standard are intended for use in the installation, operation, maintenance, repair and logistics support of military equipment/systems or for accomplishment of assigned missions and to set a style and format standard for related publications for which no other standards exist.

Marginal notations are not used in Revision A to identify changes with respect to the the original issue due to the extent of the changes.

This standard and all Military Specifications and Standards not covered by a security classification are available from Document Center Inc. at our website, www.document-center.com.  Many obsolete revisions are available as well.  And our staff can assist you in identifying replacement documents for withdrawn documents.  Just contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).

New ASTM E384 2011 Edition released on Standard Test Method for Knoop and Vickers Hardness of Materials

ASTM E384 2011 Edition, titled “Standard Test Method for Knoop and Vickers Hardness of Materials,” has been released.   This 43-page test method covers determination of the Knoop and Vickers hardness of materials, the verification of Knoop and Vickers hardness testing machines, and the calibration of standardized Knoop and Vickers test blocks.

Hardness tests have been found to be very useful for materials evaluation, quality control of manufacturing processes and research and development efforts.  Hardness, although empirical in nature, can be correlated to tensile strength for many metals, and is an indicator of wear resistance and ductility.

Because the Knoop and Vickers hardness will reveal hardness variations that may exist within a material, a single test value may not be representative of the bulk hardness.

The Vickers indenter usually produces a geometrically similar indentation at all test forces.  Except for tests at very low forces that produce indentations with diagonals smaller than about 25 μm, the hardness number will be essentially the same as produced by Vickers machines with test forces greater than 1 kgf, as long as the material being tested is reasonably homogeneous.  For isotropic materials, the two diagonals of a Vickers indentation are equal in size.  Recommendations for low force microindentation testing are also included in Appendix X5.

The Knoop indenter does not produce a geometrically similar indentation as a function of test force.  Consequently, the Knoop hardness will vary with test force.  Due to its rhombic shape, the indentation depth is shallower for a Knoop indentation compared to a Vickers indentation under identical test conditions.  The two diagonals of a Knoop indentation are markedly different.  Ideally, the long diagonal is 7.114 times longer than the short diagonal, but this ratio is influenced by elastic recovery.  Thus, the Knoop indenter is very useful for evaluating hardness gradients or thin coatings of sectioned samples.

The ASTM E384 and all ASTM test methods are available on Document Center’s website, www.document-center.com.  Additionally we have many obsolete revisions of the ASTM standards available.  You may prefer to contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com) if you have any additional questions.

New ANSI Z535 Series 2011 Editions for Safety Signs, Symbols, Labels and Tags is due to be released

The ANSI Z535 Series has been updated and is available for pre-ordering now from Document Center Inc.  The new revisions have been issued for all 6 standards in the series and will be available in September if there are no glitches in the publications process.

The six standards affected are:

ANSI Z535.1, 2006 Edition reapproved in 2011, “American National Standard for Safety Colors.”  Part 1 sets forth the technical definitions, color standards, and color tolerances for safety colors.

ANSI Z535.2, 2011 Edition, “American National Standard for Environmental and Facility Safety Signs.”  Part 2 covers requirements for the design, application, and use of safety signs in facilities and in the environment.

ANSI Z535.3, 2011 Edition, “American National Standard for Criteria for Safety Symbols.”  Part 3 provides general criteria for the design, evaluation, and use of safety symbols to identify and warn against specific hazards, and to provide information to avoid personal injury.

ANSI Z535.4, 2011 Edition, “American National Standard for Product Safety Signs and Labels.”  Part 4 defines performance requirements for the design, application, use, and placement of safety signs and labels intended to identify hazards for persons using, operating, servicing, or in proximity to, a wide variety of products.

ANSI Z535.5, 2011 Edition, “American National Standard for Safety Tags and Barricade Tapes (for Temporary Hazards).”   Part 5 covers safety tags and barricade tapes that are used to identify a temporary hazard. These types of tags shall be used only until such time as the identified hazard is eliminated or the hazardous operation is completed. For example, a safety tag would be appropriate for use during lock-out/tag-out procedures or use on a damaged tool until the tool can be properly removed from the work area. A barricade tape would be suitable to mark an area affected by a chemical spill or an open and temporary trench.

Safety tags or barricade tapes shall not be used in place of a permanent sign or label intended for hazards in normal use, operation, or maintenance. However, if a permanent sign or label is presented in a tag configuration or a hang tag is used to supplement a permanent safety sign, the safety tag should comply with the provisions of ANSI Z535.4 or ANSI Z535.2.

While this standard addresses safety tags and barricade tapes for temporary hazards, other tags or tape types are not addressed by this standard. For example, underground tapes, permanent tapes, striped tapes and non-skid tapes are not covered by this standard.

ANSI Z535.6, 2011 Edition, “American National Standard for Product Safety Information in Product Manuals, Instructions and Other Collateral Materials.”  This standard sets forth requirements for the design and location of product safety messages in collateral materials for a wide variety of products.

These and all ANSI standards are available from Document Center Inc. through our website, www.document-center.com.  Or you can contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We have been working with ANSI for many years now.  Additionally we are one of the primary outlets for both paper and electronic copies of standards that are only available via download from the ANSI website.

 

New Revision C for DI-TMSS-80527, Commercial Off-The-Shelf (COTS) Manuals and Associated Supplemental Data

DI-TMSS-80527 has recently been updated with the release of Revision C which replaces the DI-TMSS-80527B from 2006.  The new one-page Data Item Description, titled “Commercial Off-The-Shelf (COTS) Manuals and Associated Supplemental Data,” describes the format, content, and intended use information for the data deliverable(s) resulting from the work described in MIL-PRF-32216.

Data Item Descriptions are short military documents that define the data required of a contractor (like a report or manual, for example). The DID (as they are known) specifically defines the data content, format, and intended use.

The TMSS in the document number refers to the FSC classification for the document, in this case Technical Manuals, Specifications and Standards.  The DID’s now use the FSC in the number to segregate the documents by catagory.

To order this DID, or any publicly available U.S. military publication, please use our website at www.document-center.com.  Or contact our Document Center staff by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We have many obsolete revisions as well as the current editions.

RR-C-271 Revision F released on Chains and Attachments, Carbon and Alloy Steel

Federal Specification RR-C-271 Revision F has just been released.  Titled “Chains and Attachments, Carbon and Alloy Steel,” the specification covers carbon and alloy steel chain of commercial quality together with the attachments most commonly used with this type of chain.  The RR-C-271F replaces the now-obsolete RR-C-271E from December 2010.

The 45 page revision covers the following classes and styles for Type I welded steel chain:

Class 1 – Alloy chain (overhead lift), Class 2 – High-test chain, Class 3 – Transport chain, Class 4 – Proof-coil chain and for Class 5 – Twist-link chain – Style 1 – Long-link pattern (coil) and Style 2 – Short-link pattern (machine)

For Type II weldless (forged and casting) chain, the following classes are included:

Class 1 – Single-loop pattern chain, Class 2 – Double-loop pattern chain, Class 3 – Sash chain, Class 4 – Flat-link chain, Class 5 – Bead chain, Class 6 – Plumber’s chain, Class 7 – Single-jack chain, Class 8 – Double-jack chain, Class 9 – Ladder chain, Class 10 – Register chain, and Class 11 – Mechanical communication chain.

Federal specifications do not include all types, grades, classes, and styles of the commodities indicated by the title of the specification, or which are commercially available, but are intended to cover the types that are suitable for Federal Government requirements.

The RR series of Federal Specifications covers end products purchased by the U.S. Government that are made of metal.  So some items in this grouping include metal paper napkin dispensers and chain link fencing.  Many of the documents in the series have been canceled long ago, replaced by commercial item descriptions (CID’s) or withdrawn without replacement.

With new revisions of government standards, you may or may not find clear notation of the changes from the previous edition.  If you’re lucky, there will be lines in the margins (or sometimes asterisks) bringing those areas to your attention.  However, in the case of RR-C-271F, section 6.5 notes that identification of changes with respect to the previous issue are not present due to the extensive changes.

RR-C-271 and all Federal Specifications can be purchased from our website, www.document-center.com.  Or contact Document Center staff by phone (650-591-7600), fax (650-591-7617) and email (info@document-center.com).  Many obsolete copies of Federal documents are available from us as well.

 

New EN 1127-1 2011 Edition on Explosive atmospheres – Explosion prevention and protection – Part 1: Basic concepts and methodology affects those certifying to Directive 94/9/EC

BS EN 1127-1 2011 Edition, “Explosive atmospheres – Explosion prevention and protection – Part 1: Basic concepts and methodology,” has just been released.  It is the official English language edition of EN 1127-1:2011.  The administrative process of integrating the new release with the Lists of Harmonized Standards for Directives 94/9/EC and 2006/42/EC is expected to be completed shortly.

EN 1127-1 specifies general design and construction methods to help designers and manufacturers in achieving explosion safety in the design of equipment, protective systems and components at all stages of its use.  It is applicable to any equipment, protective systems and components intended to be used in potentially explosive atmospheres, under atmospheric conditions. These atmospheres can arise from flammable materials processed, used or released by the equipment, protective systems and components or from materials in the vicinity of the equipment, protective systems and components and/or from the materials of construction of the equipment, protective systems and components.

The standard specifies methods for the identification and assessment of hazardous situations leading to explosion and the design and construction measures appropriate for the required safety. This is achieved by risk assessment and risk reduction.

The safety of equipment, protective systems and components can be achieved by eliminating hazards and/or limiting the risk by using a) appropriate design (without using safeguarding); b) safeguarding; c) information for use; d) any other preventive measures.

Measures in accordance with a) (prevention) and b) (protection) against explosions are dealt with in Clause 6, measures according to c) against explosions are dealt with in Clause 7. Measures in accordance with d) are not specified in this European Standard. They are dealt with in EN ISO 12100:2010, Clause 6.

The preventive and protective measures described in EN 1127-1 will not provide the required level of safety unless the equipment, protective systems and components are operated within their intended use and are installed and maintained according to the relevant codes of practice or requirements.

The new BS EN 1127-1:2011 and all BS publications are available from Document Center Inc. through our website, www.document-center.com.  Or if you prefer, you can contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  The various publications for the EN standards can cause confusion.  If you have any questions about what publications you should be using, please contact us.

New ASME A17.5 2011 Edition just released on Elevator and Escalator Electrical Equipment

ASME A17.5 2011 Edition, “Elevator and Escalator Electrical Equipment,” is now available for ordering from Document Center Inc.  The standard is intended for anyone engaged in the safety of elevators, escalators and related conveyances.

Co-numbered ASME A17.5/CSA B44.1, the document is a joint publication of both ASME International and the Canadian Standards Association.  It is reflective of the closer working relationship CSA has had in recent years with the U.S. Standards Developing Organizations.  In fact, CSA is now the Accredited Standards Developer for the American Gas Association standards.

ASME A17.5 applies to the electrical equipment for elevators, escalators, moving walks, dumbwaiters, material lifts, and elevating devices for persons with physical disabilities (platform lifts and stairway chairlifts).  These include (a) motor controllers; (b) motion controllers; (c) operation controllers; (d) operating devices; and (e) all other electrical equipment not listed/certified and labelled/marked according to another product safety standard or code.

The equipment specified in this Standard is intended for installation in accordance with the Canadian Electrical Code, Part 1 (CSA C22.1) and the National Electrical Code (NFPA 70), whichever is applicable.  Note: Controllers, i.e. motion, motor and operation controllers, are defined in CSA B44 and ASME A17.1 (now actually another co-numbered standard as of the 2010 Edition).
