BS EN ISO 527-1:1996 pdf free.Plastics – Determination of tensile properties – Part1.General principles.
1.1 This part of ISO 527 specIfies the general principles for determining the tensile properties of plastics and plastic composites under defined conditions.
Sever& dIfferent types of test specimen are defined to suit different types of material which are detailed in subsequent parts of ISO 527.
1.2 The methods are used to investigate the tensile behaviour of the test specimens end for determining the tensile strength, tensile modulus end other aspects of the tensile stress/strain relationship under the conditions defined.

The test specimen is extended along its major longitudirial axis at constant speed until the specimen fractures or until the stress (load) or the strain (elongation) reacl’ies some predetermined v&ue. During this procedure the load sustained by the specimen and the elongation are measured.
