If your laboratory performs Pensky-Martens flash point testing, the latest ASTM D93-25 revision introduces a critical new requirement – mandatory verification using Certified Reference Materials.
This article explains what’s changed, why it matters and how to stay compliant.
What the ASTM D93 update means for laboratories
The revised standard now mandates that laboratories:
- Verify instrument performance using a Certified Reference Material at least annually
- Use materials with traceable, certified flash point values
- The Certified Reference Material should be close to the expected test range
This change strengthens data reliability and ensures traceability across laboratories. Internal checks or non-certified materials are no longer enough.
The risk of not using a Certified Reference Material (CRM)
Historically, some laboratories relied on internal checks or secondary standards. Without CRM verification, results may not meet regulatory or audit expectations and can lead to:
- Increased risk of product safety or regulatory issuesudits.
- Non-compliance with ASTM D95-25
- Failed or delayed ISO 17025 audits
- Questionable or non-defensible test results
The simplest way to stay compliant
The most effective way to meet the new requirements is to introduce a dedicated Pensky-Martens Certified Reference Material into your verification routine. This ensures traceability to recognised standards, confidence in instrument verification, consistent, repeatable verification and clear audit evidence.
