GB/T 1040.3-2006Plastics -- Determination of tensile properties -- Part 3: Test conditions for films and sheets (English PDF)

1 Scope

1.1 This Part of GB/T 1040 specifies the test conditions for determining the tensile properties of plastic films or sheets less than 1mm thick, based upon the general principles given in Part 1.

Note: For sheets greater than 1mm thick, the user is referred to GB/T 1040.2.

1.2 SEE Subclause 1.2 in GB/T 1040.1-2006.

1.3 This Part is not normally suitable for determining the tensile properties of:

a) cellular materials;

b) plastics reinforced by textile fibres.

1.4 SEE Subclause 1.5 in GB/T 1040.1-2006.
