Automotive parts | Components

The high quality and safety of materials and components of motor vehicles are the main priorities and goals of their manufacturers, as well as justified requirements of the end users. The supervision procedures during the development and production of automotive parts, all the way from raw material to the final product, requires close cooperation between qualified independent testing laboratories and the component distributers. The current principles of quality systems in the automotive sector place icreasingly greater demands on testing rooms and certification bodies. Besides the essential accreditation they are also the succesful interlaboratory comparisons and tests and lately also the frequent client audits, which require compliance with individual requlations, often beyond ITC's accreditation. ITC concentrates expert knowledge from many industrial branches and offers services to its clients from one place, thanks to the accredited testing laboratory ATL No. 1004 1004.3. From this view ITC is a significant provider of professional services that support the quality and safety in the automotive industry.

TESTING, MEASUREMENT

Common physical tests	Mechanical tests
identification of materials and their composition viscosity density weight additive content dimension, dimension change thermal properties transport phenomena of liquids and fluids optical characteristics (sheen, colour changes)	static and dynamic strength characteristic (traction, pressure, bending) Impact testing (Charpy, Izod) hardness (Shore A, D, IRHD normal a micro, plastic hardness by ball imprint) permanent deformation (traction, pressure) creep testing endurance and tire testing testing by sinus and accidental vibration resonance searching with possibility of combination with climatic influences
Ageing, climatic and corrosion testing	Testing of electrical components
temperature ageing oxygen ageing ozone ageing weather ageing colourfastness temperature chocks tests with cyclic change of climate salt fog resistant to liquids, fluids, and chemicals	EMC electromagnetic compatibility feeder influence electric strength insulation resistivity electrical parameter monitoring
Emission tests	Colourfastness, colorimetry
fooging (gravimetric, reflektometric) emission tests (total organic carbon TOC, individual substances) Formaldehyde emmision emission VOC a FOG by gas chromatography (VDA 278)	shine measurement colour measurement (L,a,b, XYZ ...for geometry 0°/45°, 7°/R) yellowness index opacity measurement colourfulness measurement
Defectoscopy	Tear, abrasion, rubbing
Identification defects reasons infrared microscopy, electron microscopy with EDS detection thermal desorption with GCMS detection, direct-inlet MS elements analysis (ultra trace analysis, analysis ICP-MS, XRF, AAS analysis of efflorescence reasons on a product surface and its prevention	rubbing by Krokmetr method abrasion by Taber test method (rotary, linear) scrape resistance cleanness, wickedness test abrasion of textile materials by Martindale Shopper method
Flammability	Sensory testing
flame temperature fire temperature burning speed match, cigarette test	sensory tests according to different automotive standards odour tests identification of an odour kind

SPECIAL TESTING METHODS

Mechanical testing of automotive seats
Mechanical testing of doors, armrests, operating equipments
Tests by the static inside overpressure of pressure circles (cooling system, brake system, fuel system)
Tests by dynamic pressure (pressure impact, pulsation + combination with mechanical vibration and temperature strain)
Expansion container – inside overpressure
Simulation of a clean box operation

STANDARDS, TESTING METHODS

Database of concern standards	VW Group Supply - Online-Normentete
ITC registers approximately 1000 automotive test methods, which are used for quick orientation in inquiries of clients. Database is not updated regularly and therefore this one has informative character only.	ITC has the contracted a registered access to system VW Group Supply.com (the information services for suppliers of Volkswagen concern). ITC is users of the „Online-Normentexte“ application, that is the tool for receiving of current version of VW standards and other technical documents.

List of automotive groups, according to their standards ITC provides testing, measurements and evaluations.
