This specification covers fuel-resistant polysulfide (T) sealing compounds supplied as a two-component system.
Five year Review. Viscosity of Curing Agent, Air Content, and Radiographic Density properties were eliminated as technical requirements in accordance with Committee vote. The Thermal Expansion shrinkage requirement changed as a result of a Committee vote. Standard Cure Time hardness requirement was changed to align with other AMS polysufide sealant specifications. For the Accelerated Storage Requirements, Standard Cure Time was added due to a deletion error and Assembly Time was removed because it is only performed on Class C materials and will not be performed for qualification tests. Clarifications were made to align with AS5502. Additional editorial corrections and clarifications were offered.
