47 CFR Code of Federal Regulations New 2010 Edition now available

Title 47 of the Code of Federal Regulations is currently being released with the October 2010 publication date and is available from Document Center Inc.  47 CFR is released in 5 books, the most notable being the volume with Parts 0 to 19.  That’s because it includes Part 15, the Federal Communications Commission (FCC) rules and regulations regarding unlicensed transmissions.  Why so widely used?  Because nearly every telecommunications device sold in the United States, from medical devices to computers, must comply with Part 15.

The Code of Federal Regulations is the “Compendium” of U.S. regulations.  Title 47 is specifically the Telecommunications regulations.  Each October 1, all the regulations under the jurisdiction of the FCC (Federal Communications Commission) are “frozen” for publication in this series.  Each Part is included in the 5 volumes exactly as it was in force on that date.

Changes can be made to the regulations throughout the year, by the process of being published in the Federal Register.  For many folks, its much easier to get the CFR volumes with the regulations that impact them than to try to keep up with the information on a daily basis.

How did the CFR’s come into existence?  They’re a result of the Reduction of Paperwork Act.

All of the CFR’s and many government documents are available from Document Center Inc. at our website www.document-center.com.  Or feel free to call us at 650-591-7600, fax us at 650-591-7617 or send us an email at info@document-center.com.  We’ll be happy to provide you with the volumes you need or answer any questions you may have about regulatory and compliance information.

New MIL-STD-2073/1E with Change Notice 1 is now available

MIL-STD-2073/1 Revision E with Change Notice 1 interfiled has just been released and is available for sale from Document Center Inc.   The document is titled Standard Practice for Military Packaging and is widely used in fulfillment of U.S. government contracts.

The MIL-STD-2073/1 outlines standard processes for the development and documentation of military packaging.  This standard covers methods of preservation to protect materiel against environmentally induced corrosion and deterioration, physical and mechanical damage, and other forms of degradation during storage, multiple handling, and shipment of materiel in the defense transportation system.

New ISO 14155, 2011 2nd Edition, just released – Clinical investigation of medical devices for human subjects — Good clinical practice

Document Center now has the new ISO 14155:2011 Edition available for purchase.  The standard, titled Clinical investigation of medical devices for human subjects — Good clinical practice, withdraws and replaces both the ISO-14155-1 and the ISO-14155-2.

ISO 14155:2011 addresses good clinical practice for the design, conduct, recording and reporting of clinical investigations carried out in human subjects to assess the safety or performance of medical devices for regulatory purposes.

The principles set forth in ISO 14155:2011 also apply to all other clinical investigations and should be followed as far as possible, depending on the nature of the clinical investigation and the requirements of national regulations.

ISO 14155:2011 specifies general requirements intended to protect the rights, safety and well-being of human subjects, ensure the scientific conduct of the clinical investigation and the credibility of the results, define the responsibilities of the sponsor and principal investigator, and assist sponsors, investigators, ethics committees, regulatory authorities and other bodies involved in the conformity assessment of medical devices.

ISO 14155:2011 does not apply to in vitro diagnostic medical devices.

This new edition, as well as all the ISO standards, is available from Document Center Inc. at our website www.document-center.com.  You can also contact us by phone at 650-591-7600, fax at 650-591-7617 or by email at info@document-center.com.  We’re always happy to help you with any standards needs you may have.

New BS EN 55024 2010 Edition released

BS EN 55024 has just been released as the new 2010 edition.  The popular standard is titled “Information technology equipment. Immunity characteristics. Limits and methods of measurement.”  The date on the new edition is January 2011 and the document is available now from Document Center Inc.

The new BS EN 55024:2010  is the official English language edition of the EN 55024 and is identical to the CISPR 24, 2010 Edition.

It establishes uniform requirements for the electromagnetic immunity of information technology equipment. BS EN 55024 specifies applicable tests, test levels, product operating conditions and assessment criteria.  Test methods are then found in the referenced Basic EMC Immunity standards.

BS EN 55024 sets out the requirements to provide an adequate level of intrinsic immunity.  The goal is for the equipment to operate as intended in its environment.  The standard specifies the immunity test requirements for equipment defined in the scope in relation to continuous and transient, conducted and radiated disturbances, including electrostatic discharges (ESD).

Some tests are specified in defined frequency bands or at selected frequencies because of testing and performance assessment considerations.  Equipment which fulfils the requirements at these frequencies is deemed to fulfil the requirements in the entire frequency range from 0 Hz to 400 GHz for electromagnetic phenomena.

The test requirements are specified for each port considered.

This standard, and many more, are available from Document Cen5ter Inc. at www.document-center.com, or by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  Feel free to contact us with additional questions.

New MIL-STD-464 Revision C: Electromagnetic Environmental Effects Requirements for Systems

MIL-STD-464C, the Department of Defense’s primary Electromagnetic compatibility (EMC) standard for systems, has just been released.  It is one of Document Center’s best selling military documents.

It is the latest in a long line of standards that goes back to at least MIL‑I‑6051, “Interference Limits and Methods of Measurement; Aircraft Radio and Electronic Installations,” released in 1950. The MIL‑STD‑464 replaced MIL-I-6051D and several other documents in 1997.

MIL‑STD‑464 is the DoD top‑level EMC (aka E3, electromagnetic environmental effects) requirement set for procurement of complete or modified systems.  This might be airborne, sea, space, and ground systems (like a tank or a submarine), including associated ordnance.

This standard contains two sections, the main body and an appendix. The main body of the standard specifies a baseline set of requirements. The appendix portion provides rationale, guidance, and lessons learned for each requirement to enable the procuring activity to tailor the baseline requirements for a particular application. The appendix also permits Government and Industry personnel to understand the purpose of the requirements and potential verification methodology for a design. The appendix is not a mandatory part of this document.

The document states that changes are too numerous to identify due to the extent of the modifications.  However, apart from a few changes to section 2, the revisions seem to cluster in section 3.

This standard, previous editions, and all other publicly distributed DoD standards are available from Document Center Inc. via our website, www.document-center.com, email (info@document-center.com), phone (650-591-7600), and fax (650-591-7617).

New JEDEC JESD22-A110D Released

JESD-22-A110 Revision D, Highly Accelerated Temperature and Humidity Stress Test (HAST),  has just been released in November.  It is one in a series of specialized tests for solid state devices maintained by the JEDEC Solid State Technology Association.

The purpose of this test method is to evaluate the reliability of nonhermetic packaged solid state devices in humid environments. It employs severe conditions of temperature, humidity, and bias that accelerate the penetration of moisture through the external protective material (encapsulant or seal) or along the interface between the external protective material and the metallic conductors which pass through it.

The change made to the new  JESD22-A110 D, compared to its predecessor, JESD22-A110 C (January 2009) is the addition of  Note 1 and Note 2 in Clause 4.5.

The change to the JESD22-A110 C compared to the JESD22-A110 B, was the addition of a note in Clause 4.4.
