PTL’s Capillary Flow and Technical Cleanliness Test Receive NEW ISO/IEC 17025: 2017 Accreditation

In addition to a recent ISO/IEC accreditation extension, PTL received a new accreditation for two highly sought-after tests. “Our latest tests garnering ISO compliance are the standard test method for pore size characteristics of geotextiles by capillary flow and the standard test method for technical cleanliness,” reports Amy Ganden, Manager of Quality Assurance and Methods Compliance.

These accreditations provide clients with an even deeper level of confidence in Particle Technology Labs’ processes and standards set by the International Standards Organization.

Capillary Flow ASTM D6767 Accreditation Standard

Capillary flow porometry (CFP) is a technique used to evaluate the through pore size distribution and permeability characteristics of a variety of materials used as membranes and filtration media. These materials include paper, synthetic polymers, cotton, ceramics, foams, and hollow fibers.

ASTM D6767 Standard Test Method for Pore Size Characteristics of Geotextiles by Capillary Flow Test was applied to this pore size distribution and porosity test.  The technique has a pore size range of 0.013 pm to 500 pm. This parameter can be invaluable where 100% rejection of particles above a certain size is required, as well as potential detection of defects.

ISO/IEC 17025: 2017 accreditation applies to testing and calibration laboratories. This accreditation allows PTL to show new and returning clients that our laboratory is competent and provides quality results as verified by a third party through a multi-faceted evaluation process. ISO/IEC standards are used in a growing a variety of industries—from automotive and aerospace to food and beverage—and are recognized internationally. 

With the broadening of our accreditation to include ASTM D6767 and ISO 16232, PTL adds to a growing list of included methods to better serve our client’s needs for reliable, quality results. 

Technical Cleanliness ISO 16232 Standard

The level of technical cleanliness is determined by the amount of contamination within components. Contaminates, foreign and minute particles can influence the quality, strength, and safety of products. Automotive, aerospace, and medical device industries require their contract lab adheres to the highest testing standards to meet the requirements placed upon them. Contamination can result in components breaking and thus having a direct impact on human lives. Clearly, technical cleanliness is a non-negotiable.

Adding Technical Cleanliness per ISO 16232 to PTL service offerings allows us to support mid-size parts manufacturer whom may not have the internal resources to comply with the ISO standard.  Working with PTL, mid-size part manufacturers will achieve quality testing and allow for broader market access within their industry.  PTL believes this is an area of growth and looks forward to continued development of small and mid-size parts manufacturers as we partner with them for Technical Cleanliness.

“Achieving these accreditations requires Particle Technology Labs to undergo highly rigorous and thorough assessments from an independent, outside third party,” explains Janna Stahl, PTL’s Business Development Manager, “I am pleased with  our team as PTL continues to set the standard for particle characterization across industries.”

Technical Cleanliness Testing

PTL offers technical cleanliness testing conforming to ISO 16232—Cleanliness of Automotive Components, as well as the Association of German Automotive Industry’s VDA 19. Through light optical analysis with the JOMESA HFD Cleanliness Analysis System, the size and counts of captured particulate are provided along with classification of metallic, non-metallic, and fiber particles.
