To complement our popular film proficiency service, Smithers Pira has now launched a new service tailored to the needs of laboratories routinely carrying out transmission rate testing on packs.
Smithers Pira has nearly 40 years’ experience in permeability testing and providing comparative testing services - Proficiency and Site Quality Manager Geoff Collis expands on the benefits for customers:
"Measuring the permeability of packs requires good control of external parameters such as temperature, relative humidity and the permeability measurement is often difficult to verify in the absence of published data.
Proficiency testing in general is an excellent way of verifying that all aspects of the laboratory measurement are sound. It can be used to validate the participating laboratory’s measurement methods, operator training and uncertainty budgets."
These proficiency services are ideal for manufacturers, converters and printers – many of whom use it as the foundation for their own ISO accreditation. Subscribers receive a full data report and personalised trend charts. Each laboratory is allocated a personalised laboratory number, so that they can compare their performance against other subscribers.
At Smithers Pira we can offer customised inter-laboratory comparative testing for specific company groups and indicative value sample packs for a range of tests.
