ASTM C773

Standard Test Method for Compressive (Crushing) Strength of Fired Whiteware Materials

The compressive strength is determined on a right cylinder. Testing of at least ten specimens per type/brand is recommended by ASTM.

$260 per test of 5 specimens

SIGNIFICANCE AND USE

Resistance to compression is the measure of the greatest strength of a ceramic material. Ideally, ceramics should be stressed this way in use. This test is a measure of the potential load-bearing usefulness of a ceramic.

1. SCOPE

1.1 This test method covers two test procedures (A and B) for the determination of the compressive strength of fired whiteware materials.

1.2 Procedure A is generally applicable to whiteware products of low- to moderately high-strength levels (up to 150 000 psi or 1030 MPa).

1.3 Procedure B is specifically devised for testing of high-strength ceramics (over 100 000 psi or 690 MPa).

1.4 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.
