New energy car battery which tests need to do?
In our life, new energy vehicles is the universal travel transportation, greatly reduce air pollution to our environment. But the important question, an important part of a new energy vehicles is how to choose a good battery? A good car battery, need to go through a layer of a layer of inspection and test, test to detect all the process, to know whether the battery is installed in the car is safe. Battery safety in new energy vehicles is very important, so to control strictly. The battery must be high temperature resistant, crushing, explosion-proof, short circuit. Below for everyone to explain the battery inspection where some equipment need to use them? 1, battery extrusion prick test: choose the battery extrusion needle machine, this machine is mainly used for simulation of batteries or batteries in by external extrusion deformation or sharp puncture after the safety and reliability of detection. By extrusion/acupuncture trials of laboratory simulation cell induced by outside force collision deformation or after piercing, at the same time get the test data ( Such as extrusion, acupuncture, battery voltage drop, the highest surface temperature and deformation of the battery, the battery extrusion/acupuncture video data, etc. ) And provide the experimental data and basis for product design optimization, as well as safety risk assessment and validation. Battery with no explosion, not as a qualified fire. 2, battery short circuit test: choose the battery short circuit testing machine, this equipment integrated a variety of battery short circuit test standard requirements and design, according to the requirements of standard short circuit device must conform to the scope of internal resistance & le; 80± 20mΩ And 5 m & Omega; To achieve maximum short-circuit current test requirements; In the circuit design of the short circuit devices also must be able to withstand the impact of high current, so we choose the industrial-grade dc electromagnetic contactor and copper wiring terminal and internal copper diversion, generous COINS, effectively increase the cooling effect of the large current short circuit devices are safer and reduce the wastage of the testing equipment, to ensure the accuracy of the test data. 3, battery impact test: choose the battery weight impact testing machine, the machine is suitable for batteries, battery ( Or battery pack) Under different quality of heavy objects from different heights through free-fall impact in batteries, battery ( Or battery pack) Products, lead to internal short circuit of destructive test, through the observation period test results for evaluation of batteries, battery ( Or battery pack) Safety performance. Batteries or battery in accordance with the relevant provisions of test method, on the surface of the platform, the diameter of 15. 8毫米± 0. 1 mm stainless steel rod cross in the center of the batteries or battery geometry on the surface, the weight of 9. ±1公斤 0. A weight of 1 kg from 610 mm & plusmn; 6 mm high hit the battery with our metal surface freefall, automatic reset after the impact, and observed for 6 h. 4, battery burning jet experiment: choose battery burning testing machine, the machine is suitable for lithium battery, Or battery pack) Flame resistance test. We manufacture a full range of battery testing equipment, manufacturing standards to meet the domestic and international test standard, not only have a single device, and rich in the design of the overall battery safety testing lab planning experience, our company successfully for many large battery production and new energy automobile enterprise installation planning, has accumulated rich experience, if you have any needs, can contact consulting, our company will provide one-on-one service and technical solutions.

Choosing the right abrasion testing equipment is essential for obtaining accurate and repeatable wear resistance results. DIN Abrasion Tester and Taber Abrasion Tester are two widely used abrasion testing machines, but they are designed for different material types and testing purposes.
This article provides a detailed comparison between DIN Abrasion Tester and Taber Abraser, covering their working principles, specimen requirements, industry applications, standard compliance, technical characteristics, operation features and practical advantages. DIN Abrasion Tester is mainly designed for rubber, elastic materials, tires, conveyor belts and footwear soles, while Taber Abrasion Tester is suitable for flat materials such as coatings, textiles, plastics, leather, metals and decorative surfaces.
By understanding the differences between these two abrasion testing methods, laboratories can select the most suitable abrasion tester based on sample geometry, testing standards and production quality control requirements.
The air permeability tester is a high-precision testing instrument designed to evaluate the breathability of PPE materials, textile fabrics, non-woven fabrics, woven fabrics, and industrial filter media. It plays a critical role in quality control, product development, and laboratory research across multiple industries including PPE, textiles, automotive interiors, and filtration systems.
Modern instruments such as the GT-C27 Air Permeability Tester are developed with advanced sensor systems, automated control logic, and multi-standard compatibility to ensure reliable and repeatable results. Complying with global standards such as ISO 9237, ASTM D737, DIN 53887, and GB/T 5453, it guarantees internationally recognized testing performance.
With high automation, accurate pressure sensing, and flexible unit conversion systems, air permeability testing equipment significantly improves testing efficiency while reducing human error. It is widely used in PPE manufacturing, textile engineering, non-woven product development, and industrial filtration quality inspection.
Personal protective equipment must meet specific performance requirements before it can be used in demanding workplace environments. ISO, EN, and ASTM standards provide important test methods and performance requirements for different PPE categories. However, the applicable standard depends on the product, intended application, target market, and specific protection requirements.
This guide explains the role of ISO, EN, and ASTM standards in PPE testing and introduces common requirements for safety footwear, protective gloves, protective clothing, masks, and safety helmets. It also explains how laboratories can select suitable PPE testing equipment according to the applicable test method.
