Product Description

Introduction:
Application of Grips and Fixtures
Grips and fixtures are key components for material testing. If you use the wrong grips and fixtures, it may affect the test results. SINOTEST provides various grips and fixtures. This catalog includes common products that are compatible with samples defined by commonly used testing standards (such as ASTM, ISO, DN, GB, BS, JIS, GOST, etc.).

Product Compatibility
This scissor action grip can be directly used for DF series Universal Testing Machine. If there are special requirements, you will need grip adapters to achieve your targets.


Selection of Grips and Fixtures
Selecting grips and fixtures are very complex, but the main focus is on the following three aspects:

1. Test load

It is recommended that the grips be subjected to a force greater than 1.25 times the expected maximum test load, which means that the grips can be operated at 80% of its capacity. The capacity of the load cell should match that of the grip (i.e. a 50 kN grip should use a load cell with a rated value of 50 kN). This can effectively ensure the accuracy of the results and a long-lasting service life.

2. Test standard

Test standards define sample size and shape. Usually, various grips & fixtures can be selected. If you are unsure, please provide specific test standard code.
3. Specimen and test method
Except sample size and shape, surface texture is also an important factor to consider when selecting fixtures. In a tensile test, improper grip selection often leads to fixture sliding, premature damage, and rupture. To help determine the correct fixture, please send us sample details and test methods.

Scissor Action Grip
The scissor action grip produced by SINOTEST adopts a lever self-locking clamping method with simple structure and firm clamping.

Standards
ISO 527-3:1995      Plastics-Determination of tensile properties-Part 3: Test conditions for films and sheets
ASTM D882-10      Standard Test Method for Tensile Properties of Thin Plastic Sheeting
GB/T 1040.3-2006    Plastics - Determination of tensile properties -Part 3. Test conditions for films and sheets
GB/T 528-2009      Rubber, vulcanized or thermoplastic -- Determination of tensile stress-strain properties
......

Features
1. Adopting lever self-locking clamping method, the clamping is convenient and reliable;
2. The clamping force is moderate, suitable for tensile testing of rubber, plastic sheets and other samples;
3. Reliable clamping without slipping.
