Standard Test Method for Low-Temperature Flexibility and Tenacity of One-Part, Elastomeric, Solvent-Release Type Sealants

SIGNIFICANCE AND USE
This test method is not intended to simulate an actual use condition but it will give some indication of the elastomeric properties or flexibility of a building joint sealant at low temperature. It can serve to differentiate between elastomer-based sealants and sealants based on nonelastic binders that can harden or embrittle on aging and crack or lose adhesion when flexed at low temperature. In addition, it can aid in identifying sealants that have poor flexibility because they are overextended and contain a very low level of elastomeric binder as well as those sealants having binders that will embrittle at low temperature.
  (a) Complete Cracking and Adhesive Failure(b) Severe Cracking  ( c) No Cracking or Adhesive FailureFIG. 1 Low-Temperature Flexibility (Tenacity)
SCOPE
1.1 This test method covers determination of the low-temperature flexibility and tenacity of one-part, elastomeric, solvent-release type sealants after cyclic high- and low-temperature aging.  
1.2 The subcommittee with jurisdiction is not aware of any similar ISO 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.
