Labthink Permeability Proficiency Service Spring 2014 was Officially Opened
2014-03-12 05:00:00| Industrial Newsroom - All News for Today
Currently various standards and test methods are applied in the permeability testing of films. However, there is no uniform standard for the accuracy of the test data. As a result, it is hard to evaluate the competency of the testing organizations or laboratories, which has become an obstacle in quality control for the film manufacturers and users. In order to provide a valuable reference for the data accuracy, Labthink launched the permeability proficiency service, which was officially opened ...This story is related to the following:Test and Measuring InstrumentsSearch for suppliers of: Permeability Testers | Testers

Labthink Permeability Proficiency Service
2014-03-04 06:00:00| Industrial Newsroom - All News for Today
1. Background and Introduction<br /> <br /> Scientific data is usually obtained through measurements. The competency of a laboratory is evaluated by the accuracy of its testing data. For the same test item, distinct test principles or test methods may be used by the test operators. However there is no one uniform standard by which the accuracy of the test results can be evaluated. Some laboratories which own the testing instruments to test OTR and WVTR of the films also face this problem. It ...This story is related to the following:Testing Services |

The Influence of Vacuum Degree on Gas Permeability Test with Differential Pressure ...
2013-09-02 06:00:00| Industrial Newsroom - All News for Today
Abstract<br /> <br /> The vacuumizing time and the vacuum degree reached by the system should be paid much attention when performing gas transmission tests with vacuum method. The vacuum degree would be reduced if the vacuumizing time is not sufficient, which would cause inaccuracy of the test results.<br /> <br /> Gas permeability of the materials is mainly tested with differential pressure method or equal pressure method, of which the former one is the most widely used and the most ...This story is related to the following:Sensors, Monitors and TransducersSearch for suppliers of: Vacuum Testers
