ElasTek Type A Test Block Kit

ElasTek Type A Test Block Kit (71430-A)

This kit gives durometer operators a fast, reliable way to confirm an instrument is still reading accurately between full calibration cycles — seven Type A blocks compounded to nominal hardness values of 30, 40, 50, 60, 70, 80, and 90 under ASTM D2240. Type A is the standard scale for general-purpose rubber and elastomer hardness, so this is typically the first kit a lab reaches for.

Each block is color coded, making it quick to identify the right reference value without checking a label every time, and the full set ships in a latching case built to protect the blocks from the kind of bench damage that would throw off a reading. Individual blocks can be reordered separately if one gets damaged or worn rather than needing a whole new set.

ISO-17025 calibration comes included with every kit, and CCSi recommends recalibrating annually to keep the reference values trustworthy — a service CCSi also provides directly. If your lab runs both A-scale and Micro/M-scale durometers, the Type A & M kit covers both from a single set of blocks rather than requiring two separate kits.
