Sponge Hardness Tester
SHORE F Durometer /SHORE F (Peak hold) Durometer
In order to measure the hardness of foam, we special tailor-Made the F type sponge durometer to facilitate our customers. It is suitable for the determination of soft foam, polyurethane foam rubber products'hardness. And itwill be different with the other hardness tester In the aspects of using. When using, the presser foot directly contact to the sample, and see it sown weight as force measuremen tload.
Main parameters:
Scope of pressure needle route: 0~2.5millimeters.
The scale value: 0-100 degrees.
The force of pressure needle end: 550mN~4300mN(56~438.5g).
Second, the method of using:
Held the middle of the instrument, located the hardness tester gently on the plane Specimens which is bigger than presser foot(orspecimen). Reading out the value in 1 second when durometers'presser foot contact with the samples moothly. And the tick of pointers is the hardness value of sample (specimen). In order to improve the
Accuracy of measurement, you should putthe sample on a flat plate glass or plate.
Each measuring point should be measured only on
Forth, Attention:
1 When the durometer presser foot is in the free state, it points "0". The pressure
Needle end and the pressure foot flat is in close contact with the glass surface, the
Indication should be "100" If the Durometers' pointer can notshow "0' and "100"
Whenchecking, adjustitto"0'and"100
2, The sample and adjustments
The specimen thicknesss houldbe in 25mm to 30mm, when insufficient thickness Of 25mm, you can stack 2 pieces. But you need to ensure the flat surface smooth, The whole thicknesss tills hould conform to the sample thickness. The sample size should satisfy thel ength and the width are larger than100mm, The distance between the measuring point and sample edge is not less than 40mm, All measuring point are less than between 25mm, each sample pointsi s not less Than five points.
Take out the skin of both sides of the specimen, the thickness should be uniform, smooth surface, micro-hole distribution uniformity, no mechanical damage and impurities. SampletestconditionsaccordingtoGB/T2941-91provisions.
