ISO 48-9 Rubber - Vulcanized or Thermoplastic - Determination of Hardness - Part 9: Calibration and Verification Test of Hardness Testers

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 48-9 testing. This standard covers type A, D, AO and AM durometers, IRHD pocket meters, IRHD constant load devices and dead load instruments using the very low rubber hardness scale.

ISO 48-9 Rubber - Vulcanized or Thermoplastic - Determination of Hardness - Part 9: Calibration and Verification Test of Hardness Testers

ISO/TC 45/SC 2 has established the principle that it will help users to group standards on the same subject, but covering different aspects or methods, preferably together with an introductory guide standard, rather than dispersing them into the numbering system. This has been achieved in some subjects such as spherometers (ISO 6502) and dynamic properties (ISO 4664).

The ambient temperature of the measuring chamber where the calibration or verification is carried out should be between 18°C ​​and 25°C.

The measurement uncertainty of the measuring instruments used in call vibration and reinforcement methods shall not be more than 0,2 times the specified tolerances. Alternative devices may be used provided that the required measurement uncertainty is respected and that these devices allow the calibration or verification methods to be carried out effectively.

A coordinate measuring device (for example, a measuring microscope) or a profile projector is suitable for measuring indentations.

The durometer is mounted on an indentation depth measuring device consisting of a length measuring system with a measuring range of 0 mm to 2,5 mm and a displacement device. For example, a digital micrometer can be used as a length measuring system. The measuring axes of the length measuring system and the hardness tester to be calibrated must be aligned and placed vertically.
