II overview

The digital Shore rubber hardness tester is an instrument used to measure the hardness of vulcanized rubber and plastic products,This instrument hasATypeDTypeCType 3 Various forms.AType andDThe types are suitable for testing the hardness of low to medium hardness and high hardness rubber materials.CType is suitable for compression ratios of50%At that time, stress0.049MPaWhen using the above, rubber and plastic are used together, and the plastic contains foaming agent to make the microporous material hardness for shoes
The testing. This hardness tester performsGB/T531、GB2411、HG/T2489、JB6148Regarding regulations.

III Technical Parameter

1. Measurement range:0-100Degree.

2. Measurement error: in20-90Within the degree,error≤±1Degree.

3. divide distinguish Rate:0.5Degree.

4. Needle stroke:0-2.5mm.

5. 5.Pressure at the end of the pressure needle:
ATypeCtype0.55N-8.05N
Dtype0-44.5N

4 Usage

Place the sample on a sturdy surface,Hold the hardness tester,The distance between the pressure needle and the edge of the specimen should be at least12mmstable Pressing the foot firmly onto the specimen means that the pressure needle is pressed vertically into the specimen until the foot is in complete contact with the specimen1sInternal reading. At the measuring point At least a distance apart6mmMeasure hardness values at different locations5Next, take the average value (the distance between the measuring points of the microporous material should be at least15mm）. For stability To determine the measurement conditions and improve the measurement accuracy, the hardness tester device should be tested on the same type of measuring rack produced in conjunction with it.

FiveInstructions for use

Before use, check that the pointer of the hardness tester should display zero in the free state. If it does not display zero, use the reset buttonZEROReset to zero). When pressing the hardness tester onto a glass plate, it should display100±1Degree (tight contact between the end face of the pressure needle and the bottom face of the pressure foot and the glass plate). If not instructed0and100±1When pressing the pressure needle lightly, it can be pressed a few times, but if it still does not display0and100±1When the temperature is high, it cannot be used. When used on a fixed load rack, the handle can be pressed to make the hardness tester fully contact the pressure foot of the hardness tester and the test bench under the gravity of the weight. At this time, the numerical display should100±1The degree can be fine tuned using the two adjustment handwheels under the test bench, if it still cannot be adjusted100±1The degree cannot be used either, it is advisable to send it to the factory for adjustment.DWhen the hardness tester is held and pressed on glass to check the zero position, the cargo device must place a hard specialized measuring block under the pressure foot of the hardness tester when adjusting the zero position on the fixed load measuring rack. Otherwise, the hardness tester pressure head will damage the glass plate and it is difficult to accurately indicate the value. Rubber samples should be tested according toGB/T531-99The preparation of plastic samples should comply with the requirementsGB2411-80The preparation of rubber microporous material samples should comply with the requirementsGB2489-93If possible, the preparation of rubber and plastic samples should be carried out according to the requirements before measurementGB0T2941/GB/T2918The regulation is to adjust it at the laboratory standard temperature before measurement. When using the sampleAThe measured value of the hardness tester exceeds90When using it, it is recommended to useDType hardness tester, whenDThe measured value of the hardness tester is lower than20When measuring, it is recommended to useAType hardness tester.AThe reading of the hardness tester is lower than10The measurement results are inaccurate and cannot be used. After use, the hardness tester should be wiped clean and placed in the instrument box in a dry place to prevent moisture.
