Standard Test Method forASTM_D2583-13a.png

Indentation Hardness of Rigid Plastics by Means of a Barcol

Impressor


1. Scope

1.1 This test method covers the determination of indentation

hardness of both reinforced and nonreinforced rigid plastics

using a Barcol Impressor, Model No. 934-1 and Model No.

935.

1.2 The values stated in SI units are to be regarded as

standard. The values given in parentheses are for information

only.

1.3 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.

3. Terminology

3.1 Definitions—For definitions of technical terms pertaining

to plastics used in this test method, see Terminology D883.


4. Summary of Test Method

4.1 A material’s surface hardness is determined through the

use of a Barcol Impressor. The relative depth of penetration of

the Impressor’s indentor provides a comparative measure of

the material’s hardness. The Model No. 934-1 and Model No.

935 Barcol Impressors are designated for use with plastics.

Within the range of hardness measured by these Impressors the

Model No. 934-1 is used for measuring harder materials and

the Model No. 935 is used for measuring softer materials.


5. Significance and Use

5.1 The Barcol Impressor is portable and therefore suitable

for testing the hardness of fabricated parts and individual test

specimens for production control purposes.

5.2 Before proceeding with this test method, reference shall

be made to the specification of the material being tested. Table

1 of Classification System D4000 lists the ASTM material

standards that currently exist. Any test specimen preparation,

conditioning, dimensions, or testing parameters or combination

thereof covered in the relevant ASTM material specification

shall take precedence over those mentioned in this test method.

If there are no relevant ASTM material specifications, then the

default conditions apply.
