The Auto LPG containers are subjected to a series of vigorous tests and consistent quality is successfully demonstrated through the tests mentioned below:

BONFIRE TEST
It is the most critical test and is designed to demonstrate that a container complete with all accessories as specified in the design, will not burst when tested under the specified fire conditions such as direct impingement of fire on the container filled with LPG,etc. This safe guards the end users in the event of a fire in the automobile.
 
■ Designed to demonstrate that a container complete with the fire protection system specified in the design qualifies the test requirements
■ CCOE Approved site in strict compliance to Explosive Rules to conduct Bonfire test as per safety Norms
■ Zero Failure on about 30 Occasions of Type Tests conducted in the presence of BIS,CCOE
■ A uniform fire source of 1.65 m long is provided by a Diesel Burner
■ Uniform heating is maintained throughout the test
■ Provision to Measure Temperature at 4 specified locations & at intervals of 30 sec is made
■ Qualified technicians conduct the test


CRASH TEST
It is the most stringent test and designed for ensuring the leak proof quality of the container when it is subjected to crash/collision against deformable wedge at a speed of Min.50 KM/H. Further after completion of the test the container shall show no leakage at a test pressure of 1.1Mpa.
 
■ A Horizontal & Un deformable Wedge defined by two faces of a dihedron of 90 Deg. Apex is used
■ Length of wedge > Container Length
■ Wedge is located perpendicular to drive direction of vehicle
■ Arrangement of the container to make a collision with the wedge at a min. speed of 50Km/hr existing
■ Manpower with technical know-how perform the test


FATIGUE TEST
It guarantees the minimum thickness of the container set by the design. During this test the container is filled with water and subjected to successive reversal of hydraulic pressure under specified cycles. The container is then subjected to burst test for conformity
 
■ Successive reversals of upper & lower cyclic pressures are given by hydro Pneumatic Pumps
■ Frequency of reversals of pressure < 0.25 Hz
■ Temperature measurement on outer surface at regular intervals done
■ Trained manpower conduct test


BURST TEST
■ Hydro Pneumatic Pump which enables the pressure to be increased at an even rate
■ Max Flow rate is ensured < 3% of the capacity of the container per minute
■ Measurement of Volumetric expansion of the container is made
■ Measurement of pressure is done at regular intervals


MECHANICAL TEST
■ Universal Testing Machine for Mechanical testing to find yield strength, UTS and elongation on test specimens of container along with attachment for bend test is used
■ Examination of full transverse section of weld by Macro etching is done
■ In-house Hardness testing facility existing


LEAK PROOF TEST
■ 100% Containers are inspected for leak proof


RADIOGRAPHY TEST
■ Radiography on 2% of Containers production in consideration of weld joint factor 0.85
■ Radiography on 10% of Containers production in consideration of weld joint factor 1
