Overview
SUNDOO LXB-D Rubber and Plastic Shore Shore Durometer is a double-pointer D-type Shore Shore Durometer designed according to GB/T531 and JJG1039-2008 standards, specially designed to test the Hardness of vulcanized rubber and plastic products. The hardness gauge can not only be equipped with a bracket test, the measurement is more stable, but also can be hand-held directly on the equipment for rubber or sponge surface hardness testing.
Features
1. Dual pointer design, including tracking pointer (black) and peak pointer (silver)
2. Can be equipped with bracket test, stable measurement
3. Handheld direct surface hardness testing
4. Dedicated to hardness testing of vulcanized rubber and plastic products
5. Complies with a number of national standards and verification procedures
Principle
LXB-D rubber and plastic Shore Shore Durometer applies pressure to the sample by pressing, the pressure needle Travel range is 0~ 2.5mm, the pressure at the end of the pressure needle is F = 445HD (mN), HD is the Shore D hardness gauge reading, and the Hardness value of the material is determined by measurement of the depth of pressing.
Applications
Vulcanized rubber, plastic products, sponge materials
Standards
GB/T531.1-2008、ISO 7619-1:2004、JJG1039-2008、GB2411-80
Steps
1. Prepare samples that meet the requirements according to the sample type
2. Store hardness gauge at room temperature 23 ℃ +/- 5 ℃ environment for at least 1 hour
3. Optional bracket test or handheld direct test
4. Align the crimp to the specimen surface for measurement
5. Read the Hardness value displayed by the double pointer
Notice
• The thickness of the rubber sample is not less than 6mm, the width is not less than 25mm, and the length is not less than 50mm.
• When the thickness of the sample is less than 6mm, no more than 3 layers of the same film can be used to overlap the measurement
• The film needs to be kept parallel up and down
• The plastic sample is square, with a side length of 50mm and a thickness of not less than 5mm
• The surface of the rubber and sponge specimens should be smooth and flat, free from mechanical damage and impurities
• The room temperature during verification is 23 ° C +/- 5 ° C. The hardness gauge should be stored at this temperature for at least 1 hour before verification
