ISO 1926Rigid cellular plastics -- Determination of tensile properties
ISO 1926 specifies a method of determining the behaviour of rigid cellular plastics materials when they are subjected to a tensile stress.
It applies primarily to cellular materials having a compression resistance sufficient to permit suitable gripping of the test specimens. If it is impossible to grip the test specimen, the method is modified so that the ends of the specimen are reinforced with metal plates.
Before conducting ISO 1926, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
