Standard Test Method for Surface Strength of Paper (Wax Pick Method) (Withdrawn 2010)

Significance and Use

Many printing and converting operations require the surfaces of the paper to have sufficient transverse strength to give satisfactory results. Since no absolute values are obtained with this test method, test results should be correlated with actual performance of the material during the subsequent coating, converting, printing, or packaging operation.4

For coated paper, where a significant portion of the casein or starch coating adhesive has been replaced with a thermoplastic resin, there is very little, if any, correlation between printing press performance and wax test results. The molten wax forms a stronger bond with the coating containing thermoplastic resin and the resulting pick causes the paper to appear weak, when in fact it is not.

5.2.1 For those sheets containing latex and similar substances, a more direct method employing the actual medium to be applied is recommended.

Scope

1.1 This test method covers uncoated and coated papers. It is designed to measure the surface strength of paper or its resistance to picking. It is not applicable to loosely felted papers such as blotters or roofing felts, nor to some coated papers containing thermoplastic resins in the coating adhesive.

1.2 This test method is technically similar to TAPPI T 459.

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.
