(Practice)Standard Practice for Sealing Rigid Wall Tactical Shelters with Polysulfide Based Sealants
Standard Practice for Sealing Rigid Wall Tactical Shelters with Polysulfide Based Sealants
SIGNIFICANCE AND USE
This recommended practice is intended to provide information on the storage, mixing, handling, and application of polysulfide based sealants. Tooling and equipment requirements for the satisfactory application of the sealants to joints in tactical shelters are also provided.
SCOPE
1.1 This practice covers the procedures for sealing rigid wall tactical shelters. It outlines the techniques for the storage, mixing, handling, and application of polysulfide based sealants.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 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.
