CLS CERTIFICATION, 10 YEARS AND COUNTING FOR ANGUS…
Angus Macdonald, Sales Director and Co-Founder of A&S International started 2022 by undertaking the recertification of his qualifications as a Certified Lubrication Specialist. Thereby continuing his certification and ongoing membership of the Society of Tribologists and Lubrication Engineers (STLE), since November 2012.

A Certified Lubrication Specialist, though often designated as a “Lubrication Engineer” is not limited to this, as many industry individuals from varied backgrounds, recognise the value in becoming CLS certified to increase their credibility/standards. And particularly with the esteem and acknowledgement of high standards that STLE certification holds within the lubrication industry.
A Lubrication Specialist’s Core Responsibilities
- Evaluates and selects lubricants to use and their purchases.
- Conducts lube surveys.
- Trains lubricators and assembles work list.
- Develops quality assurance and used lubricant analysis programs. Troubleshoots and problem solves lubrication issues.
- Maintains records of all application, as well as waste collection or disposal.
As part of our recognition in the value of this important accreditation within the industry we are partnered with the world acclaimed Michael D Holloway of 5th Order Industry, to offer training and competency development via his online courses.
“I can’t speak highly enough of the CLS qualification, the lubrication knowledge and understanding it has empowered me with through my career to date has been invaluable. For those colleagues within the industry not yet certified I’d thoroughly recommend looking into obtaining certification.”
Angus Macdonald, January 2022
