In order to provide reliable and accurate test data verification service, Labthink organized The 2014 Spring Permeability Proficiency Service. The event, guided and supervised by authoritative experts of domestic packaging industry, was widely supported and participated by testing organizations and laboratories.
By June 30th 2014, more than 120 organizations and laboratories submitted the test data. Participants involved quality inspection organizations of national, provincial and municipal level, company laboratories, third-party testing centers, and 10 laboratories from seven countries.
The event employed many different test methods and obtained abundant test data. Test methods for water vapor transmission rate (WVTR) included gravimetric method, electrolytic method, infrared method; while differential pressure method and equal pressure method were for test of oxygen transmission rate (OTR). Instruments applied were from different manufacturers, and of different models even from same manufacturers, such as Labthink, Mocon, etc. Test data thus obtained could objectively represent the domestic or even global testing capability and current testing level relating to permeability of materials.
The event came to a successful conclusion on July 10th 2014. We owed greatly the success to support from participants and elaborate guidance of experts. Labthink sincerely invites you for The 2014 Autumn Permeability Proficiency Service to be held soon.
