Shore D Scale Durometers Test the Hardness of Pipeline Coating, Hard Rubber, Acrylic, Delrin, Kevlar, PVC, Nylon, Lexan, and Epoxies.
A Type D Durometer is designed to measure ASTM (American Society for Testing and Materials) D2240 Type D hardness. It can be used with a test stand or hand-held.
Model 307L is the industry standard for the oil, gas, and coatings industry.
Meets standards like NACE, ASTM D2240, or ISO 868
Pipeline Coating Hardness Testing — What You Need to Know
Pipeline coatings are essential for protecting pipes against corrosion, abrasion, and mechanical damage. Measuring the hardness of these coatings ensures they meet durability and performance standards, especially for buried pipelines, subsea infrastructure, or high-pressure systems.
Recommended Use Cases
Rigid thermoplastics (e.g., ABS, polycarbonate, nylon)
Hard elastomers
Ebonite and hard rubbers
Epoxy resins
Plastic casings and structural parts

CALIBRATION CHECK
For a complete calibration check of mainspring, and visual and mechanical check of indenter, the instrument should be returned to PTC® (see Guarantee &Calibration Service) or refer to ASTM D2240 Specifications. PTC® recommends the unit be returned at least every 12 months for this check. For a quick field check, follow the guideline below. Under no circumstance should a test block be used as a standard to calibrate a durometer.
1. The pointer should read zero when no force is applied to the indenter of the durometer.
2. Hand hold the durometer and insert the indenter into the hole of the calibrated test block. Apply enough force to make firm contact between the top surface of the test block and the base of the durometer. The dial reading should agree with the value stamped on the check block (±1). Several tests should be made and the results averaged.
3. The indenter must protrude 0.098 to 0.100 inches below the base of the durometer.
4. When the indenter is fully displaced, the durometer should read 100 points. Use care as to not damage the tip of the indenter.
