1. lntroduction
Barcol lmpressor is an indentation hardness tester originally made in the USA. It has 3 models in series. 934-1 is the typical model which is in widest application.
Barcol lmpressor is mainly applied in two areas: One is aluminum fabrication industry, to test pure aluminum, soft aluminum alloys, thick aluminum alloys, aluminum belts, aluminum alloys extrusions, bars, castings, forgings and assembled aluminum alloy parts (e.g. Al-alloy door &window, curtain wall etc.) Relevant standard is American standard ASTM 8648-00 《Test Method for Indentation Hardness of Aluminum Alloys by Means of a Barcol lmpressor》;the other is fiber reinforced plastics industry, most of the domestic and abroad fiber reinforced rlastics products are required to test Barcol hardness. Relevant standard is American standard ASTM D2583-07 《Test Method for Indentation Hardness of Rigid Plastics by Means of a Barcol lmpressor》.

934-1 barcol hardness tester is a kind of portable hardness tester, it is the typical model which is in widest application mainly used for rapid hardness test for aluminum and aluminum alloy, as well as fiberglass reinforced plastic. Barcol hardness tester has the simple operation by just single hand and wide measuring range, no experience to be needed. It can be applied to all the aluminum and aluminum alloy, only need to contact one side to finish the test. |
