ASTM D774/D774M-97(2007)

Bursting strength is widely used as a measure of the resistance to rupture in many kinds of paper. The test is relatively easy and inexpensive to make and appears to simulate some use requirements.

1.1 This test method covers measurements of the bursting strength of paper and paper products occurring as single or laminated flat sheets not over 0.6 mm [0.025 in.] in thickness having a bursting strength of 30 kPa up to 1400 kPa [4 psi up to 200 psi].

1.2 This test method is not intended for use in testing corrugated boxboard, liner board, or hardboards that tend to cut the thin rubber diaphragm.

Note 1—Similar procedures for making bursting strength measurements are found in ISO 2758 and TAPPI 403.

1.3 The values stated in either SI units or in other units shall be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way.

1.4This 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.
