The producer is permitted awide latitude in choice of raw materials for making theseproducts. Con

9、sequently, there is no implication that the com-pounds are equivalent in all physical properties.4.3 The manufacturing process shall be such as will ensurea homogeneous mix, free of defects that would affectserviceability, and of a consistency suitable for immediateapplication.5. General Requirement

10、s5.1 Standard ConditionsPerform all of the tests in acontrolled environment at standard conditions. Condition seal-ant samples for at least5hatthese conditions before any testsare performed.5.2 The sealant in the original container shall be suitable foruse for at least 12 months from the date of man

11、ufacture whenstored at a temperature neither below 5C (41.0F) norexceeding 27C (80.6F).5.3 The color of the sealant shall be as agreed upon betweenthe purchaser and the manufacturer.5.4 The sealant shall be intended for use only on clean, drysurfaces. When a primer is recommended by a manufacturerfo

12、r a specific substrate, all tests on that substrate shall includethe primer. The proper use of primers (or surface conditioners)with the application of sealants is described in detail in GuideC1193. This guide also describes proper methods for jointdesign, backup materials, surface preparation, tool
