Durometer Test Block Hardness Standards

Since type “A” durometers test rubber and other softer non-metallics, it is possible for the user to imbed the foot of the durometer into the test specimen and obtain false readings.

The TBK-A kit consists of seven color-coded test blocks each of which measure 1/4" x 2" x 2". The blocks are calibrated and correspond to durometer values of 30 pts. to 90 pts. in increments of 10. The kit comes to you in a sturdy magnetic-latching carrying case with the true readings for each block on the inside cover of the case. A certificate of calibration is also included for users who need documentation of traceability to NIST. Single test blocks for other durometer scales are also available.

The Type D durometer tests the hardness of hard rubber and plastics. While not to be used for calibration purposes, the TBK-D Kit also enables the user to perform a quick check for the proper operation of the durometer.

This kit consists of three color-coded test blocks each measuring 1/4" x 2" x 2". The Kit is furnished with a sturdy magnetic-latching carrying case with the true readings for each block on the inside cover of the case. A certificate of calibration is also included for users who need documentation of traceability to NIST.

Since type OOO durometers test soft rubber, foams, gels and other very soft non-metallics, it is possible for the user to imbed the foot of the gauge into the test specimen and obtain false readings.
