Testing machine standards updated! Covering 300+ varieties, tension, compression, bending and shear testing is more accurate

Recently, the National Standardization Administration Committee released the latest version of testing machine technical standards, covering the mechanical property testing of more than 300 materials and products, involving key test items such as tension, compression, bending, and shear. This update aims to improve testing accuracy and industry standardization levels, and provide a more reliable technical basis for manufacturing, scientific research institutions and testing laboratories.

1. Core changes in the new standards

Testing machine standards updated! Covering 300+ varieties, tension, compression, bending and shear testing is more accurate

The new version of the standard has been optimized mainly from three dimensions: test methods, equipment calibration, and data collection. The specific adjustments are as follows:

projectold standardnew standardUpgrade meaning
Tensile test accuracy±1%±0.5%Reduce misjudgment of material strength
Compression test range50-1000kN10-5000kNCovering super soft/super hard materials
Data sampling frequency100Hz500HzCapture transient deformation data

2. Statistics on covering material types

For the first time, the new standards include emerging fields such as composite materials and biomedical materials into the scope of mandatory testing:

Material categoriesSpecific number of varietiesAdd new items
metal material112High entropy alloy testing specifications
Polymer materials89Creep testing of 3D printing materials
building materials45Low carbon concrete durability
Other special materials54Artificial bone compression modulus

3. Industry Impact Analysis

This standard update will directly affect three major areas:

1.Testing agency: Equipment upgrades need to be completed before the end of 2024, and it is expected that there will be an additional 230 million yuan in testing equipment procurement demand across the country.

2.manufacturing companies: The cost of material certification in the automotive, aerospace and other fields may increase by 15%, but the product qualification rate is expected to increase by 8%.

3.Research schools: 47 university materials laboratories have launched special research projects on new standards.

4. Key points of technology upgrade

In order to meet the requirements of the new standards, testing machine manufacturers have focused on optimizing the following technologies:

• Use AI real-time compensation algorithm to eliminate system errors

• Upgraded high-rigidity frame structure (rigidity increased by 40%)

• Equipped with modular test tooling (switching efficiency increased by 60%)

5. Implementation Timetable

This standard update is the largest upgrade in my country's testing technology field in the past five years, and will significantly enhance the quality voice of "Made in China". Relevant companies should carry out technical adaptation as early as possible to avoid affecting the progress of product certification.
