ISO 11432 Building Construction - Sealants - Determination of Compression Resistance

EUROLAB, together with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 11432 testing. The principle of the specified method is to prepare test specimens in which the sealant to be tested adheres to two parallel contact surfaces, compress the test specimens to a defined value under defined conditions, and record the stress produced by the applied force.

ISO 11432 Building Construction - Sealants - Determination of Compression Resistance

Test specimens in which the sealant to be tested is adhered to two parallel substrate surfaces are compressed with a defined percentage of the original width and the recorded force.

The substrate material used for the preparation of test specimens as defined in ISO 13640 shall be selected from mortar or anodized aluminum or glass. Other substrate materials may be used as agreed by the parties concerned.

The sealant manufacturer's instructions, for example, a primer and mixing procedure will be used for multi-component sealants. The hollow volume will be filled with the sealant created by the surfaces.

The following measures will be taken:

  • The formation of air bubbles will be prevented;
  • The sealant must be pressed into the contact surfaces of the substrates;
  • The infill surface should be leveled so that it is flush with the faces of the substrates and substrates.
