Classification of universal material testing machines

HD-B604-S

According to the capacity, it can be divided into: single column (within 2000N) and double column (above 2000N);

According to the method, it is divided into two types: vertical and horizontal;

According to the control method, it is divided into two types: motor control (below 100KN) and hydraulic control (above 100KN);

The use of universal material testing machine

It can be applied to various industries such as hardware, metal, rubber and plastic, textiles, shoes and clothing, electronic wires, adhesive products and other industries. The tension and compression cycle and other test methods.

Each test standard

1. Peel off GB/T2790, 2791, 2792 and other test standards

It is mainly used to perform 90-degree or 180-degree peel force test on composite film, artificial leather, woven bag, film, paper, adhesive, tape, self-adhesive and other materials

Sensor used for self-adhesive test: 50N (but for adhesive, the corresponding sensor needs to be configured according to customer samples)

Selected fixtures: generally aluminum plane fixtures

Test speed: 300mm/min

Material width: 25mm

Roller weight: 2000g

The precision of the force value of the pulling machine is required to be level 1 (1/10000)

Test results: generally find the average value of the peeling interval

2. Metal stretching (GB/T228-2002)

Mainly suitable for testing the tensile strength, elongation, yield strength (yield strength), tensile maximum force, elastic modulus and other test results of metal materials;

Test capacity: generally more than 2T

Select fixture: generally a wedge-shaped fixture (the jaws of the sheet and the bar are different)

Specimen requirements: The test sample is required to be in the shape of a dumbbell (Figure 6-2-1)

Test rate requirements (Figure 6-2-2)

3. Shear test (GB/T 7124)

This standard is mainly for the shear test method of adhesive rigidity to rigidity

Suitable for special products within 2T up to 5T

Sample test size 12.5*25±0.25mm

Test rate: generally within 65±20s

Test result: Shear strength Mpa=maximum force/paste area

4. Bursting test (GB/T 19976)

This standard specifies the method for measuring the bursting strength of fabrics by using a spherical ejector, including the bursting strength test of samples in two states of conditioning in the standard atmosphere for testing and soaking in water.

The inner diameter of the ring holder is 45±0.5mm

The diameter of the ball is 25±0.02mm or 38±0.02mm

The speed of the testing machine is 300±10mm/min

5. Puncture test (GB 20655)

This standard applies to the determination methods of protective clothing materials

Test speed: 100±10mm/min

The hardness of the test needle is 60HRC,

Center diameter of test ring: 20±5mm

6. Tear (GB/T 529 pants type, right angle type, crescent type tear)

This standard applies to vulcanized or thermoplastic rubber tearing methods

Test speed: trousers tear: 100±10mm/min right angle tear and crescent tear: 500±50mm/min

Test thickness: 2mm
