Construction and Building Materials. Send us a request Wilton UK: The test complements the measurement of glass transition temperatureas an indirect measure of the degree prlcedure cure of a composite. The specimen is placed under the indentor of the Barcol hardness tester and a uniform pressure is applied to the specimen until the dial indication reaches a maximum.
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Data is expressed as Barcol numbers given by the instrument.
The depth of the penetration is converted into absolute Barcol numbers. Originally called the Barber-Colman Impressor, the Barcol impressor was developed by Walter Colman as a hand-held, portable means of assessing the hardness of a material during World War II. Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards procsdure virtually any market around the world.
Standards can be obtained from appropriate standards authorities.
