2.5mm 1HD Shore Hardness Gauge IEC 60335-2-80 Clause.20.101

Shore Hardness' gauge IEC 60335-2-80-clause.20.101

20.101 Fan blades, other than those of fans for mounting at high level, shall be guarded unless their leading edges and tips are rounded and
– they have a hardness less than D 60 Shore

Shore Hardness' gauge Type D: applicable to hard rubber, hard resin, acrylic, glass, cushiony plastic cement, printing plates, fiber, etc.

Using methods
When using single pointer models, one should place the sample in the solid plane, hold the hardness gauge, keep the pressure needle at a distance of at least 12 mm from the edge of the sample, smooth enough pressure in the pressure on the sample, and smoothly press on the
sample to a full extent. One should press the pressure needle vertically to the sample, and until pressed to a full extent and contact the sample completely, then read the calibration value within one second.
At measuring points which are at least 6 mm away from each other, measure hardness values for five times, and calculate the average value(for microporous material, the distance between the measuring points should be at least 15 mm)
. In order to keep the stability of conditions and improve the accuracy of determination, one should install the hardness gauge on the same type
of the measuring shelf from a complete production network. When using double pointer models to do measurement, one should rotate the supporting pointer to the wax, etc.
