Hardness Conversion Digital Rockwell Hardness Tester of Plastics Conform ASTM D785
1, iqualitrol XHRS-150A Digital Plastic Rockwell Hardness Tester has novel appearance interface menu, can test plastic and metal, measuring device adopts grating sensor and computer control, hardness indication directly displays on the LCD screen is the mechanical and electrical integration hardness testing machine.
2, The hardness testing of plastics is most often measured by the Rockwell hardness test or Shore (durometer) hardness test. Both methods measure the resistance of the plastic toward indentation, thereby providing an empirical hardness value.
3, These hardness values do not necessarily correlate to other properties or fundamental characteristics.
Rockwell hardness is generally chosen for 'harder' plastics such as nylon, polycarbonate, polystyrene, and acetal where the resiliency or creep of the polymer is less likely to affect the results.
4, The Ball Indentation Hardness test (ISO 2039-1; DIN 53456) is used in Europe much more often than in North America. The Barcol hardness test is sometimes chosen for thermoset polymers.
ASTM D785 - 08(2015) Standard Test Method for Rockwell Hardness of Plastics and Electrical Insulating Materials.
Main functions and features:
1. Directly display the test hardness value through the large LCD screen;
2. The shell is made by a special sandblasting process with a one-step casting process. The structure is stable without deformation and can work in a relatively harsh environment. The car has a high-grade paint and a strong anti-scratch ability. It is still bright as a new product for many years.
3, We have our own R & D design, production and processing capabilities, machine life to provide parts replacement and maintenance upgrades;
