ASTM C834-14

Standard Specification for Latex Sealants

ABSTRACT
This specification covers latex sealants used for sealing joints in building construction. The following are the type and grade of sealant under this specification: Type OP, Type C, Grade 18°C, Grade 0°C, and Grade NF. The sealant shall be composed of latex formulated with appropriate fillers, pigments, and chemical additives. The physical properties of the sealant shall conform to the specified requirements according to type and grade. The following tests shall be done: extrudability after aging, artificial weathering, volume shrinkage, low-temperature flexibility, extension-recovery and adhesion, slump, staining, and tack-free time.
SIGNIFICANCE AND USE
8.1 This specification covers two types and three grades of latex sealants as described in Section 4 that are formulated for general caulking and sealing operations in building construction. It should be recognized by the user that not all sealants meeting this specification are suitable for all applications and all substrates. It is essential, therefore, that the type and grade be specified for proper description of a sealant. Test methods relate to special standard substrates of glass, wood and aluminum. If tests are required using substrates in addition to or other than standard, they should be so specified for testing.  
8.2 Refer to Guide C1193 for information on the proper use of sealants meeting this specification.
SCOPE
1.1 This specification covers one component latex sealants used for sealing joints in building construction.  
1.2 A sealant meeting the requirements of this specification shall be classified by the manufacturer to be one of the types and grades defined in Section 4.  
1.3 The values stated in SI units are to be regarded as the standard. The inch-pound in parenthesis are provided for information purposes only.  
1.4 The following precautionary caveat pertains only to the test method portion, Section 10, of this Specification: 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.
Note 1: Currently, there is no ISO standard similar to this specification.
