Why Purafil’s Lab Certification Goes Further Than the Competition

You may have seen recent announcements about competitors receiving ISO/IEC 17025:2017 accreditation for their labs. While this is a recognized certification, it’s important to understand the scope behind it.

Purafil’s ISO/IEC 17025:2017 accreditation is broader and more rigorous, covering the critical procedures required for new media production, quality assurance, and long-term performance validation. Purafil’s accreditation certifies that our testing procedures have been validated throughout all stages of the life cycle of the media from manufacturing to final application, therefore our Certificates of Conformance, Certificate of Analysis and Media Life Analysis (MLA) are ISO/IEC 17025:2017 accredited.

In comparison, the competitor’s scope is more limited and targeted primarily toward MLA testing. Their certified procedures include permanganate content, sodium hydroxide, sodium thiosulfate, bulk density, phosphoric acid, and corrosion coupon analysis. However, they do not cover the most essential procedures that ensure ongoing performance and physical durability:

Abrasion loss & crush strength (media integrity under real-world use)

Moisture content analysis (water is used to maintain the impregnation chemicals in solution to provide higher gas capacity)

Permanganate content for new media production (ensuring the purple media will meet or exceed the published gas removal capacity by verifying that enough chemicals are present on the pellets)

Carbon pH testing (ensuring the carbon media will meet or exceed the published gas removal capacity by verifying that enough chemicals are present on the pellets)

Purafil’s accreditation demonstrates our commitment to the highest level of testing rigor, product reliability, and customer trust.
