Scope

This standard specifies a method for evaluating the hardness of petroleum wax by measuring the depth of penetration of a standard needle.
This standard is applicable to petroleum wax with a penetration value not exceeding 250.
Note: This method is similar to the GB/T 4509 method for determining the penetration of asphalt. The cone penetration method for lubricating grease and petroleum grease is described in GB/T 269.
This standard uses units of the International System of Units (SI).
This standard involves certain hazardous materials, operations, and equipment, but it does not intentionally address all safety issues related to them. Therefore, users should establish appropriate safety and protective measures and determine applicable management systems before using this standard.
