Barcol Impressor is a kind of indention hardness tester. It uses a special shape indenter impressed into the specimen by a standard string pressure and measures the indentation depth to obtain hardness value. It has 3 models in series. 934-1 is the typical model which is in widest application. Barcol Impressor is mainly applied in two areas: One is Aluminum fabrication industry, to test pure Aluminum, soft Aluminum alloys, thick Aluminum alloys, Aluminum belts, and Aluminum alloys extrusions, bars, castings, forgings and assembled Aluminum alloys parts (e.g. al-alloy door &window, curtain wall etc.) Relevant standard is American standard ASTM B648-00 (Test Method for Indentation Hardness of Aluminum Alloys by Means of a Barcol Impressor); the other is Fiber Reinforced Plastics industry, most domestic and abroad Fiber Reinforced Plastics 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 Impressor).
It is Used to test the hardness of all kinds of Aluminum, from very soft Aluminum to very hard Aluminum alloys. Extended application. Model 934-1 is applied to test the hardness of Aluminum, Aluminum alloys, Copper, Copper alloys, Fiber Reinforced Plastics and rigid plastics etc. The improved model of it is available to test very soft metals such as lead and tin and other soft materials such as soft plastics, rubber, felt and leather etc. High sensitivity. Featured with 100 scales, much more sensitive than Webster hardness testers applied in Aluminum alloys industry. No supporting required. Can test from only one side of the workpiece. No need to move or support the workpiece. Used to test super large and thick worpieces and assembly parts. Easy conversion. The test results can be converted to HB, HR, HV and HW easily through conversion table.
Features of Barcol Hardness Tester 1.Easy to Use: Single hand operation; easy to use high efficiency able to make test at any site. 2.High Sensitivity: Barcol Impressor has 100 graduations. Its sensitivity is much higher than the Webster hardness tester. 3.Wide Testing Range: Used to test from very soft pure aluminum to very hard aluminum alloys. 4.Less Thickness Requirement: It can test on any workpieces with thickness greater than 0.8 mm. 5.No Supporting Required: It can test from only one side of the workpiece. It is unnecessary to move or support the workpiece. It is used to test very large and thick worpieces and assembly parts. 6.Easy Conversion: The test results can be converted to HB, HR, HV and HW easily through the conversion table. 7.High Quality Indenter: The indenter has very high hardness, long service life and good interchangeability Technical Parameter of Barcol Hardness Tester Testing Range: 0 - 100 HBa (equivalent to 25 - 145 HBW) Resolution: 0.5 HBa Indication Error: ±2 HBa (42 ~ 48 HBa) ±1 HBa (81 ~ 88 HBa) Repeatability Error: ±2 HBa (42 ~ 48 HBa) ±1 HBa (81 ~ 88 HBa) Net Weight: 0.5 kg
