Lube suppliers should provide you with a document confirming the quality of the lubricant. What is this document called?

The document confirming the quality of the lubricant is known as the Certificate of Analysis. This document serves a crucial role in the lubrication process, as it provides detailed information about the lubricant's composition, including tests and analyses that verify its properties such as viscosity, purity, and performance characteristics. The Certificate of Analysis is typically issued by the lubricant manufacturer or supplier and ensures that the product meets the specified criteria and standards, thereby ensuring that it is suitable for its intended application.

The other documents mentioned serve different purposes. The MSDS (Material Safety Data Sheet) primarily focuses on the safety and handling of chemicals but does not provide specific quality analysis. A Haz/Mat Code refers to codes related to hazardous materials and is not a document that verifies the quality of lubricants. Instructions may provide guidance on the application and use of the lubricant but do not confirm its quality or composition. Therefore, the Certificate of Analysis is specifically designed to certify the quality and attributes of the lubricant in question.
