1. Scope | ||||||||||||||
1.1 This test method covers the empirical estimation of the consistency of waxes derived from petroleum by measurement of the extent of penetration of a standard needle. This test method is applicable to waxes having a penetration of not greater than 250. Note 1: This test method is similar to the needle method for
determining the penetration of bituminous material, Test Method
D5. Cone methods applicable
to greases and to petrolatum are described in Test Methods
D217 and Test Method
D937,
respectively.
