MIL-STD-740-1, Airborne Sound Measurements and Acceptability Criteria of Shipboard Equipment, inactivated for new design

MIL-STD-740-1, “Airborne Sound Measurements and Acceptability Criteria of Shipboard Equipment,” has been inactivated for new design.  If you need the inactivation notice 1, it’s available now from Document Center Inc. in either paper or pdf format.

The standard is still current for use for replacement purposes (existing applications).  However, for new design, you should use the ‘Shipboard Equipment Noise’ requirement section of MIL-STD-1474, ‘Noise Limits.’

This inactivation notice follows on the heels of the cancellation notice for the MIL-STD-740B, which we discussed in a previous blog.

All current and many obsolete Military specs and standards are available from Document Center Inc. at 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 here to help you with your standards requirements and questions.

MIL-STD-740 Revision B canceled for Airborne and Structureborne Noise Measurements and Acceptance Criteria of Shipboard Equipment

MIL-STD-740B, “Airborne and Structureborne Noise Measurements and Acceptance Criteria of Shipboard Equipment,” has recently been canceled.  The standard covered acceptable instrumentation and procedures for the measurement and acceptance criteria for airborne and structural noise of Naval shipboard equipment.  It has been replaced by three other standards, all of which are available from Document Center Inc. now.

MIL-STD-740-1, “Airborne Sound Measurements and Acceptance Criteria of Shipboard Equipment,” MIL-STD-740-2, “Structureborne Vibratory Acceleration Measurements and Acceptance Criteria of Shipboard Equipment,” and the “Shipboard Equipment Noise” Requirement of MIL-STD-1474, “Noise Limits,” supersede MIL-STD-740.

Standards on acceptable noise levels provide criteria for designing materiel that:

a. minimize noise induced hearing loss,
b. permit acceptable speech communication in a noisy environment,
c. minimize aural detection by an enemy,
d. minimize community annoyance, and
e. provide acceptable habitability of personnel quarters.

All current and many obsolete military specifications and standards are available from Document Center Inc. at our website, www.document-center.com.   We’ve been selling mil specs and standards since the early 1980’s.  We not only provide the documents themselves, but providing updating services so that you don’t need to worry about keeping your standards collection current when you purchase them from Document Center.
