Barcol Hardness Tester Barcol Impressor 934-1
Barcol Impressor is a kind of indention hardness tester originally made in the USA. 934-1 is the typical model which is in widest application.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) As a measuring instrument, Barcol Impressor has its relevant verification regulation JJG-1989 (Barcol Impressor). This regulation is used for verification of Barcol Impressor newly manufactured, under used and after maintenance.
Key feature
·Smar t and por table, can be used by single hand operation
·Wide valid testing range equivalent to Brinell hardness
25-150HBW
·Used to test the hardness of all kinds of Aluminum, from ver y
sof t Aluminum to very hard Aluminum alloys
·934-1 is applied to test the hardness of Aluminum, Aluminum
alloys, Copper, Copper alloys, Fiber Reinforced Plastics and rigid plastics etc.
·High sensitivity - Featured with 100 scales, much more sensitive
than Webster hardness testers applied in Aluminum alloys industry.
·No suppor ting 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
