Standard Practice for Sealing Rigid Wall Tactical Shelters with Polysulfide Based Sealants
SIGNIFICANCE AND USE
4.1 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3.2.3.1 Discussion—
Acceptability limits for Class B extrudable sealants are expressed in terms of the extrusion rate of a sealant from a 6 fl oz (180
mL) cartridge through a nozzle with a 0.125 in. (3.2 mm) diameter orifice, using air pressure of 90 6 5 psi (620 6 34 kPa) in a
pneumatic sealant gun. The extrusion rate is expressed in grams per minute or on cc per minute. A minimum extrusion rate after
the stated application time is given as the acceptable limit. Sealant applied after the application time is exceeded tends not to wet
the surface well and thus not to form a good bond. This term should not be used
