Comprehensive Test List

Comprehensive Test List

TestOil has written work instructions for all testing procedures represented in the comprehensive test list below. Work instructions are controlled documents, and only the current revisions are available to laboratory staff. Where possible, test methods conform to ASTM standards.

TestOil participates in interlaboratory proficiency testing programs - statistical quality assurance programs that enable laboratories to assess their performance in conducting test methods within their own laboratories when their data are compared against other laboratories that participate worldwide in the same program.

Test methods are also developed in-house by our team of experts. These tests are fully developed, documented and validated before being put into use.
