This practice may be used to determine the viability of an RTV sealant to withstand pressure leak testing before cure at maximum gap conditions of a system. This practice may be used to indicate an RTV’s acceptability to undergo an assembly line leak check without causing a leak path due to material blow out.

1.1 This practice provides a means to determine the blowout resistance of a room-temperature vulcanized elastomer system (RTV) using a standard fixture.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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.
