Scope

1.1 This test method covers the measurement of thickness of any nonmagnetic material by means of a digital magnetic intensity instrument.

The instrument on which this test method is based is no longer sold or serviced.

1.2 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.

1.2 There is no similar or equivalent ISO standard.

Significance and Use

This test method is useful for measuring the wall thickness of plastic vessels and other plastic structures where the geometry of the equipment does not permit direct measurement by conventional methods, such as micrometers, calipers, and rulers. This test method is not limited to plastics and can be used for all nonmagnetic materials. It provides for a rapid and accurate thickness measurement, without the need for drilling and repair of holes.

Accuracies are not affected by density variations, permitting the measurement of composites made up of a variety of materials of varying densities. By placement of the magnetic source on the mold surface, thickness measurements can be made during and after fabrication of plastic products to verify thickness and adherence to specifications.
