Standard Test Method for
Abrasion Resistance of Petroleum Wax Coatings1

This standard is issued under the fixed designation D 3234; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This test method covers determination of the abrasion
resistance of glossy smooth coatings of petroleum wax or
wax-based blends applied to paper and paperboard.

1.2 The values stated in SI units are to be regarded as the
standard. The values given in parentheses are provided 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.

2. Referenced Documents

2.1 ASTM Standards:
C 190 Test Method for Tensile Strength of Hydraulic Cement Mortars2
D 1834 Test Method for 20° Specular Gloss of Waxed

3. Terminology

3.1 Definitions of Terms Specific to This Standard:

3.2 abrasion resistance of a wax coating—the resistance to
change in gloss when that coating has been subjected to an
abrading action by a hard external object.

4. Summary of Test Method

4.1 Sixty grams of sand are dropped at a controlled rate on
a very small area of a coating under fixed conditions. Gloss is
measured with a 20° specular glossmeter before and after this
abrading action by the falling sand.

5. Significance and Use

5.1 A test method to measure the abrasion resistance of
petroleum wax coatings on paper and paperboard helps predict
the resistance to change in gloss that coatings may undergo. An
example of a critical wax coated material is a waxed frozen
food carton, which must resist change in gloss when the
