Specifications for Test Substrates

ISO 13640 specifies the procedures for producing substrates of mortar, glass and anodized aluminium used for testing sealants.

The purpose of these requirements is to ensure the reproducibility of the standardized tests conducted on sealants through the precise definition of both

the composition and the method of preparation of the test substrates.

*** Before conducting this ISO standard  , it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
