ASTM C920-18 Specification for Elastomeric Joint Sealants

ASTM C920-18 test method covers the properties of a cured single-or multicomponent cold-applied elastomeric joint sealan t for sealing, caulking, or glazing operations on buildings, plazas, and decks for vehicular or pedestrian use, as well as types of construction other than highway and airfield pavements and bridge. The final results of this method are displayed keeping in view the international standards and inch-pound units.... Read More

    ASTM C920-18 test method determines the characteristics of sealants and helps specify their use on the basis of their type, grade, and class. Not all sealants have the same applications and properties; therefore, they must be tested for their specifications. The results obtained from this method help in quality assurance, performance evaluation, and research. 


    The specimen is manufactured as per the specified measurements, and limits are specified for the chemical composition of the material. The hardness, effects of heat aging, adhesion, cohesion, stain and color change, track-free time, rheological properties, and extrusion rates are determined. The extrusion rate is also determined, and the applications of the sealants are specified. The method also covers the packaging, marking, and certification. 

    Specimen Size:

    Specimen size should be as per the requirements. In this case, the specimen abiding by the international standards is taken for efficient testing.


    The method covers the certification, sampling, testing, and inspection of the specimen within the set limits. 


    ASTM C920-18 test method is specifically important for the quality assurance and durability check of sealants.
