fatigue life testing	automobile pipeline performance
automobile coating performance

 

test significance:

as the basis for vehicle production, the quality of automotive vehicle production materials is a prerequisite for success. with a variety of new models of increasingly sophisticated functions and people feel the constant pursuit car, auto makers must be the source of the material to monitor quality and safety, maxim automotive business unit can detect for metals, polymers, leather, textiles, etc. include a variety of mechanical properties and reliability analysis, including all aspects of monitoring.

 

testing purposes:

the physical properties including electrical properties, mechanical properties, optical properties, thermal properties, elastic and anelastic and other related, these performance parameters support the quality of the entire material. physical testing of materials is one of the longest life control means see quality, by specific numerical values to determine whether the material consistent with its requirements, basic components of detection technology.
