Instruments for the testing of air traveler bag in automobiles
An air traveler bag should be rigorously tested before use in vehicles and automobiles, as explained in this article.
Automobile air traveler bag testing ensures more accurate, responsive, and reliable airbag performance. One of the passive safety systems for autos is the airbag, which is directly linked to passenger safety.
As a result of traffic accident analysis, two-thirds of car crush accidents occur in front of cars; therefore, front airbags are used more widely.
A great deal of importance is placed on the design, development, and manufacturing of airbags in order to achieve better performance. Contents:
1. Testing of airbag permeation in automobiles
The material of an automotive airbag is a laminated film of rubber and nylon. A working airbag is filled with helium.
It is essential that the airbag fills rapidly. Passengers must be stopped by the fast-filled bag that can also exhaust quickly. Hence, the excellent and proper permeation performance of airbags is very important.
The Labthink DM 2/330 Differential and Equal Pressure Method Gas Permeability Tester can test film and laminated materials including airbag laminated materials. This tester can perform differential pressure and equal pressure measurements simultaneously. It can test three specimens simultaneously in three chambers. Gases such as poisonous, explosive, and others are also tested. During storage and when triggered by heat, the temperature control range of this device is 5C to 95C, which is very convenient for testing permeability.
2. Smoothness and Ease of Opening Automotive Air traveler bag
The smoothness and ease of operation of automotive airbags are important factors for backup airbags and quick reaction when a passenger is in danger. Airbags are made from rubber-coated nylon. In order to test airbag smoothness and ease of opening, Labthink Instruments Co. has developed the following airbag testers:
The kinetic and static coefficient of friction tests can be conducted on plastic films, foils, sheets, and papers using the MDX Series of Coefficient of Friction Testers. Airbag safety can be assured by testing the smoothness of the materials. The MDX-01, MDX-01A, and MDX-02 products are included in this series.
It can test the coefficient of friction between room temperature and 99.9 Centigrade, as well as the peeling strength of laminated films and adhesive products, which is essential for airbag testing.
4. Testing Instruments for Air traveler bag Seals and Leaks.
When the sensor receives an emergency signal, the airbag should be filled instantly with burning helium. As a result, automotive airbag integrated seal and leak testing is an important indicator of airbag quality. Test airbag seal and leak performance with PARAM Leak Tester from Labthink Instruments.
Observation of the emergent airbag in distilled water with inside-out pressure difference determines whether Labthink PARAM MFY-01 Leak Tester meets the requirements. The tester is easy to operate and controlled by a microprocessor. The device provides accurate data in compliance with ASTM D3078 and GB/T 15171.
5. Instruments to test the peeling of automobile airbags.
It consists of outer nylon material and inner rubber material. As a result of long-term storage for emergency purposes, a long period of aging, a good peeling resistance strength of the nylon and rubber layers is very important to avoid insufficient gas filling caused by rubber layer peeling.
Laboratory Instruments Co., Ltd. has introduced the PARAM XLW series of auto tensile testers to meet airbag peeling testing demand. A laminated film or adhesive tape can be tested for tensile, peeling, deformation, tearing, and adhesive strength using this tester. XLW Series Auto Tensile Testers are mini-computer controlled and capable of testing multiple data points with high accuracy and reliability. These testers are equipped with professional software. Also, they are complying with ASTM, ISO, JIS, and GB standards.
