5 Wax Lab Tests

Posted: August 11, 2017

Throughout the wax blending process, we perform tests to ensure consistent, high-quality products with the desired properties, characteristics and results. Our on-site laboratory team uses a variety of scientifically proven wax quality control tests, including:

Wax lab testing

1. D938-05

This test measures the congealing point of petrolatums and waxes. The congealing point is the temperature where a liquid starts to harden. It is important to know the congealing point of waxes because, for different applications, the wax may need to stay liquid for a longer period of time.

2. D87-09

The D87-09 test is the standard test method for the melting point of petroleum waxes. Petroleum waxes include paraffin and microcrystalline wax. It is important for the wax to have a higher or lower melt point for different applications.

3. D1833-87

This lab test is standard for the odor of petroleum waxes. In some applications, like food packaging, the smell of the wax is an important property to test. This test uses a universal numerical scale to rate odor intensity of petroleum waxes.

4. D1500-07

The D1500-07 test measures the color of petroleum products, including petroleum waxes, lubricating oils, heating oils and diesel fuel oils. This test measures colors ranging from white to black. It can also measure for tint and depth of color in the product.

5. D1321-10

This test measures the needle penetration of petroleum waxes. It tests the consistency of the wax blend by penetrating a needle into the wax. The needle penetration amount is measured on a scale to determine hardness.
