ISO 8339 Test Fixture Building Construction — Sealants
Determination of Tensile Properties (Extension to Break)
ISO 8339 specifies a method for the determination of the tensile properties of sealants used in joints in building construction.
NOTE : A method for the determination of tensile properties at maintained extension is specified in ISO 8340.
Substrate materials, used for the preparation of test specimens as defined in ISO 13640.
The substrate materials shall be selected from mortar and/or anodized aluminium and/or glass.
Other substrate materials may be used as agreed by the parties concerned.
For each test specimen two substrate pieces of the same material are required with a cross section of dimensions
Test substrates of other dimensions may be used, but then the dimensions of the sealant bead and the area of adhesion shall be the same
Spacers, of cross section (12 mm × 12 mm) with anti-adherent surface.
*** Before conducting ISO 8339 , it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
