Organization: ASTM International
Publication Date: 1 March 2007
Status: inactive
Page Count: 9
ICS Code (Plastics in general): 83.080.01
significance And Use:

Data obtained by this test method may be used to compare the heat-softening qualities of thermoplastic materials.

This test method is useful in the areas of quality control, development,... View More

scope:

1.1 This test method covers determination of the temperature at which a specified needle penetration occurs when specimens are subjected to specified controlled test conditions.

1.2 This test method is not recommended for ethyl cellulose, nonrigid poly(vinyl chloride), poly(vinylidene chloride), or other materials having a wide Vicat softening range.

1.3 The values stated in SI units are to be regarded as standard.

1.4 Due to the potential safety and environmental hazards associated with mercury-filled thermometers, the use of alternative temperature measuring devices (such as thermocouples and RTDs) is encouraged.

1.5 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 1-This test method and ISO 306:1987(E) are technically equivalent, with the exception of the allowance for creep, prior to beginning the test, in this test method.
