BARCOL HARDNESS TEST PROCEDURE PDF

The Barcol hardness test is generally used on soft materials such as rigid plastics. Qualitests Analog and Digital models are designed for accurate hardness measurement on fiber-glass glass-reinforced plastics, duro plastics, hard thermo plastics, aluminum, semi finished and finished products, according to the Barcol method. Barcol Hardness Tester - Impressor. The test is performed using a similar method and indentation device as that used to measure Shore D hardness however the Shore D indentor has a round tip.

The Barcol hardness test characterizes the indentation hardness of materials through the depth of penetration of an indentor, loaded on a material sample and compared to the penetration in a reference material. The method is most often used for composite materials such as reinforced thermosetting resins or to determine how much a resin or plastic has cured. The test complements the measurement of glass transition temperature , as an indirect measure of the degree of cure of a composite.

It is inexpensive and quick, and provides information on the cure throughout a part. 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. The Barcol hardness test is generally used on soft materials such as rigid plastics. It measures hardness based on indentation of a sharp point with a flat tip.

The test is performed using a similar method and indentation device as that used to measure Shore D hardness , however the Shore D indentor has a round tip. From Wikipedia, the free encyclopedia.
