Organization: NPFC
Publication Date: 30 December 1986
Status: active
Page Count: 30
scope:

This standard prescribes instrumentation and procedures for the measurement and analysis of, and maximum acceptable level criteria for structureborne vibratory acceleration generated by shipboard equipment.

Structureborne sound testing is conducted to demonstrate that equipment levels are within the limits specified herein.

This standard supplements specifications and similar documents applicable to shipboard equipment.

Implementation guidance is provided in section 6.

The basic method used in this standard to determine equipment acceptance is the measurement of the structureborne vibratory acceleration level (La) in decibels (dB). Measurements are required at the locations of 5.3.2 for use in guiding maintenance.

Structureborne acceptance criteria are specified in 5.1.

Equipment is acceptable when none of the structureborne vibratory acceleration levels measured using accelerometers at the designated location exceed the applicable structureborne acceptance criteria.

intended Use:

This standard is intended for use for equipment acquisition testing.

This standard also prescribes certain warning plate requirements and drawing and manual information requirements for... View More
