Labthink C130H Gas Permeability Tester is based on manometric method and conforms to ASTM D1434, while C206H Oxygen Transmission Rate Test System is based on the coulometric sensor method and conforms to ASTM D3985 Two primary methods are employed for gas permeability measurement: the manometric method and the equal pressure method. Washington — New fact sheets from NIOSH are intended to help workers at gas stations and convenience stores – and their employers – reduce the risk of violence on the job.. Workers in these settings face a greater risk of violence than others in the retail sector and the overall workforce, the agency says.Base ring: One base ring that can isolate a test area of 50mm diameter (Fig. 1b) is supplied, which can be bonded to the test surface. Additional rings can be ordered separately and are available with a variety of test areas. Special bases (Fig 1c) for clamping to the test area rather than using adhesive are available.
