Testing Services

NGC Testing Services has a range of advanced equipment for the analysis, identification, and measurement of a wide range of materials. We offer the following facilities for analytical and physical property testing.


Analytical / Physical Test Standards

ASTM C518 - Steady-State Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus (R-Value)

This test method provides a rapid means of determining the steady-state thermal transmission properties of thermal insulations and other materials.

ASTM E96 - Water Vapor Transmission

These test methods cover the determination of water vapor transmission (WVT) of materials through which the passage of water vapor may be of importance, such as paper, plastic films, other sheet materials, fiberboards, gypsum and plaster products, wood products, and plastics.
