New MIL-STD-769 Revision K – Naval Vessel Insulation

MIL-STD-769 Revision K, “Insulation Requirements for U.S. Naval Vessels,” has just been released.  This is the first update of the standard since 1990 and includes a title change (Revision J was titled “Thermal Insulation Requirements For Machinery And Piping.”)  The new edition represents the efforts of NAVSEA’s chief engineer to create a comprehesive standard for all types of insulation materials and applications.  It relies on inch-pound measurements.

One of the primary goals in issuing this new MIL-STD-769 K is to improve the use of approved materials for anti-sweat pipe insulation to bulkheads or compartments.  So there are updates to the requirements for piping, acoustic, transmission loss, fire and anti-sweat treatments.  This insulation is used in compartments, hulls, vent ducts, and overheads.  And of course, this means that the installation requirements have changed as well.

The changes to MIL-STD-769 K are extensive, so you will not find the usual lines in the margins that are sometimes used to alert you to the location of updates.

What’s included in the new MIL-STD-769?  The 117-page standard starts out with the usual scope, referenced documents, and definition clauses.  There is a 4-page section on General Requirements, then the Clause 5 on Detailed Requirements takes over.  Requirements covered in clude anti-sweat and refrigerant insulation, refrigerated store spaces, surface piping and piping components insulation, thermal and acoustic insulation and so on.  The document is completed by a short notes clause.
