1.1 This test method describes two procedures for measuring the rigidity of polyolefin film and sheeting.

1.2 Procedure A prescribes a procedure using high-voltage static eliminators and the use of TFE-fluorocarbon-coated plates to overcome the spurious effects of static electricity and friction.

1.3 Procedure B prescribes the use of a fine powder on uncoated plates to achieve a similar effect.

Note 1

Although the two procedures are designed to achieve similar effect, they may not achieve the same results.

1.4 The values stated in SI units are to be regarded as standard. The values given in brackets are for information only.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Note 2

There is no known ISO equivalent to this standard.


The rigidity of a polyolefin web can affect its machinability, particularly on those packaging machines where a cut portion of a web is required to remain flat momentarily without being supported on all sides.

Rigidity is not a simple property since it depends on two other properties of the sample: the thickness (gauge), and the stiffness which is an inherent property of the material of which the film or sheet is made. The combined effect of these two factors is the rigidity that influences performance on converting machines.
