Automotive air bag testing could be a economical guarantee for a lot of correct, reactive and reliable performance of air bag. Air bag is one among the passive protection systems for automotives, that is directly linked to passenger safety.
According to traffic accident analysis, 2 thirds of automotive crush accidents are happening in front of cars; so, front air bag system is a lot of broadly applied.
In order to possess higher performance, air bag style, development and manufacture are all vital. The contents are as follows:
1. Automotive Air Bag Permeation Testing
The material of automotive air bag could be a laminated film of rubber and nylon. Air bag is crammed with helium when operating.
The speedy filling of air bag is of nice importance. it's a requirement for the passenger
to be stopped by the quick crammed bag which may conjointly exhaust promptly. Therefore, wonderful and correct permeation performance of air bag is extremely necessary.
Labthink DM 2/330 Differential and Equal Pressure technique Gas Permeability Tester will check film and laminated materials together with air bag laminated material. This tester will execute differential pressure and equal pressure within the same chamber. 3 specimens will be tested simultaneously in three chambers. Poisonous, explosive and alternative gases will be tested in addition. The temperature management vary is 5C-95C, that is extremely convenient to check the permeability performance of airbag throughout storage and when triggered by heat.
2. Automotive Air Bag Smoothness and Open Easiness Tests
Good smoothness and open easiness of automotive air bag are very important to backup air luggage and fast reaction when the passenger is in peril. the fabric of air bag is rubber coated nylon. so as to check air bag smoothness and open easiness, Labthink Instruments Co. Ltd introduces airbag testers as follows:
A. MXD Series of Coefficient of Friction Tester is applicable in static and kinetic coefficient of friction check to plastic film, foils, sheets and paper. Through testing the smoothness of the materials, airbag safety will be absolute to meet the strain. This series of product includes MXD-01, MXD-01A and MXD-02.
B. FTP-F1 Friction/Peel Tester: is pc management, and may check the fabric coefficient of friction between space temperature and ninety nine.9 Centigrade in addition as peeling strength of laminated films and adhesive product, that is extremely necessary to air bag testing.
3. Automotive Air Bag Tensile Testing and Impact Testing
Automotive air bag receives the signal from the sensor, and turns open at intervals some seconds therefore on shield passenger. Since the open speed to its full is during a restricted time of zero.3 seconds therefore on resist shock and attack from the skin. Therefore, it's a requirement for air bag with smart tensile performance.
In order to ensure wonderful tensile performance, Labthink Instruments Co. Ltd. introduces new series of tensile and impact testers in line with international laws and standards.
A. Labthink PARAM XLW Series Auto Tensile Testers will check tensile, deformation, tearing, pierce, peeling and alternative things for films, laminated films and versatile packaging materials, etc. place the air bag specimen onto the clamps, set the testing speed and begin testing.
B. Automotive Air Bag Impact Resistance Testing
At the terribly moment of air bag gap, it'll build an area to unharness the forward strength of the passenger. Air bag impact performance management will forestall air bag breakage owing to low flexibility therefore on effectively avoid protection failure of low air bag quality. Usually, impact is tested with falling dart impact tester.
Labthink introduces new BMC-B1 Falling Dart Impact Tester to check air bag impact resistance by falling dart technique. it's to check the relevant strength required to tear the air bag material in line with ASTM D 1709, JIS K 7124 and GB 9639, etc. the complete testing method is automatic; testing knowledge are processed by minicomputer.
4. Automotive Air Bag Seal and Leak Testing Instruments
Automotive air bag ought to be crammed instantly by the burning helium when the sensor got the emergency signal. Therefore, automotive air bag integrated seal and leak testing is a very important index for automotive air bag quality. Labthink Instruments Co., Ltd. introduces PARAM Leak Tester to check air bag seal and leak performance.
Labthink PARAM MFY-01 Leak Tester determines whether or not the air bag meets the wants through observation of emerged air bag in distilled water with inside-out pressure distinction. This tester is of easy operation and micro-computer management. It complies with ASTM D3078 and GB/T 15171 and provides correct knowledge.
5. Automotive Air Bag Peeling Testing Instruments
Automotive air bag is created of the outer nylon material and therefore the inner rubber. attributable to the long-term storage for emergency, an extended amount of aging, smart peeling resistance strength of the nylon and rubber layers is extremely necessary therefore on avoid insufficient gas filling caused by rubber layer peeling.
Labthink Instruments Co. Ltd. introduces PARAM XLW series of auto tensile testers therefore on meet the testing demand for air bag peeling. This tester is applicable to check tensile, peeling, deformation, tearing and adhesive strength of laminated films and adhesive tapes. PARAM XLW Series Auto Tensile Testers are mini-computer management, and may check multiple knowledge with reliable and correct results. These testers are equipped with skilled software. Also, they're complying with ASTM, ISO, JIS and GB standards.
