Overview
LX-A Shore A hardness gauge is an instrument of LEEB brand suitable for testing the hardness of materials such as medium and low hardness plastics, leather, various types of rubber, polygrease, wax, etc. This product meets the requirements of the national GB/T531-1999 standard and other related standards, and is equipped with a special test frame to improve the test accuracy.
Features
1. Suitable for medium and low hardness plastics, leather, all kinds of rubber, multi-fat, wax and other materials.
2. Comply with relevant national standards such as GB/T531-1999.
3. Equipped with a special test rack, stability testing conditions, improve test accuracy.
4. Test frame is equipped with pressing handle, fixed load weight, adjustable Glass table, hardness gauge clamping arm and lifting column, easy to operate.
Principle
The hardness gauge characterizes the hardness of a material by pressing the pin vertically into the specimen and measuring the depth of indentation. When the pressing foot is in full contact with the specimen, the hardness value on the dial is read within 1 second. For accurate results, it is recommended to install the hardness gauge on a matching test rack to ensure that the applied force is stable and vertical.
Applications
Medium and low hardness plastics, leather, various types of rubber, polygrease, wax and other materials hardness testing
Steps
1. Place the specimen on a solid surface.
2. Hold the hardness gauge and make sure that the crimp is at least 12mm away from the edge of the sample.
3. Press the pressure foot firmly on the sample, so that the pressure needle is pressed vertically into the sample.
4. When the pressure foot is in complete contact with the sample, read the hardness value within 1 second.
5. Test 5 times at different locations with measuring points at least 6mm apart (microporous material at least 15mm), and take the average value.
6. In order to improve the accuracy, it is recommended to measure the hardness gauge device on the matching test rack of the same type.
Notice
• The needle should be at least 12mm away from the edge of the specimen.
• The reading should be completed within one second of full contact with the specimen.
• Average measurements should be taken at least 5 times at different positions, with a spacing of at least 6mm between measuring points (at least 15mm for microporous materials).
For more stable and accurate results, a dedicated test rack is recommended.
Do not exceed the recommended measurement range (10~ 90HA).
