Compliance with following International Standards:
- ASTM D3954
Purpose:
- This instrument is suitable for detecting the dropping point of all non-liquid waxes including paraffin wax, microcrystalline wax, polyethylene wax, blended wax and natural wax.
Summary of test method:
In this test method, the dropping point is defined as the temperature at which the wax suspended in a cylindrical cup. with a 2.8-mm diometer hole in the bottom, flows downward a distance of 19 mm to interrupt a light beam as the sample is heated at a constant rate in air.
Apparatus Details:
The complete test assembly consists of following parts & accessories
1) Grease Cup:
- A chromium-plated brass cup conforming to ASTM Standard D566
