(Practice)Standard Practice for Inspection Procedure for Use of Anaerobic Thread Locking Compounds with Studs (Withdrawn 2020)
Standard Practice for Inspection Procedure for Use of Anaerobic Thread Locking Compounds with Studs (Withdrawn 2020)
ABSTRACT
This practice covers an inspection procedure to ensure that studs installed with an anaerobic thread locking compound have achieved the necessary backout resistance. Verification of fastener locking effectiveness of anaerobic compounds shall be done. After inspection, the joint assembly shall be completed and final torque applied.
SCOPE
1.1 This practice covers an inspection procedure to ensure that studs installed with an anaerobic thread locking compound have achieved the necessary backout resistance.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
WITHDRAWN RATIONALE
This practice covers an inspection procedure to ensure that studs installed with an anaerobic thread locking compound have achieved the necessary backout resistance.
Formerly under the jurisdiction of Committee F25 on Ships and Marine Technology, this practice was withdrawn in December 2020. This standard is being withdrawn without replacement due to its limited use by industry.
