Aging
Interior emissions
Fire testing
Thermal Analysis
Appearance testing
Cleanliness of components and protection of systems by filtration
Mechanical testing
Non-destructive testing
To ensure safety and performance compliance, SGS’s wide testing scope includes all types of materials including plastics and polymers, rubbers, composites, metals, paints, coatings and varnishes. Assessments can be made on aging, interior emissions, fogging and odor/smells. We conduct physical and filtration testing and also mechanical and non-destructive testing.
AGING
• Carbon arc lamp (more dedicated to Japanese OEMs) Test chambers are programmable for temperature and humidity, as well as water spraying (simulating a cycle of morning dew and graining). Chambers for sun simulation testing of parts vary from 1 m³ to 14 m³. Interior parts can be tested with or without snow-white coffin. We assess visual aspects like color change, the gloss, the sticky effect, orange peel effect and changes in dimension and clearance of the mechanical resistance as well before and after aging. Applicable standards: ISO 4892, ISO16474, ISO 105-B02, VW PV3929, BMW AA-0236, FCA 50451, Toyota TSH 1585. under extreme conditions (humidity, temperature, sunlight exposure, thermal shocks) in order to check resistance and behavior. SGS provide test chambers from a few liters up to walk-in chambers, which are programmable in temperature and humidity, rapid temperature variation, vacuum option, ozone aging or thermal shocks (air/air or by immersion) for small samples as well as for complex and large vehicle parts. We assess visual aspects like color change, gloss, changes in dimension and clearance by using an optical laser 3D scanner (GOM) as well as mechanical resistance before and after aging. Applicable standards: ISO188, ISO1431, VW PV1200, Ford BI106-03, Nissan M0132, GMW14124, PSA D451139. CLIMATIC AGING TESTING Climatic tests are used for simulating ageing
CORROSION TESTING • Constant humid corrosion (up to 10 m 3 ) • Neutral Salt Spray (NSS) • Acetic Acid Salt Spray (AASS) • Copper Accelerated Salt Spray (CASS) • Condensation and immersion
• Cycled corrosion testing (CCT, alternating salt spray cycle, temperature and humidity cycle and drying cycle): 3C corrosion, SWAAT test, Renault ECC1, PSA TCAC, Herel test, Dr Diehl, Volvo ACT, C4S, ECC2, CCT-1, NVDA After corrosion testing, SGS can conduct pitting analysis, brazing quality analysis, filiform corrosion, weld bead analysis, coating thickness measurements. Applicable standards: ISO9227, ASTM B117, Daimler DBL7392, RNES-G-00005 (ECC1, CCT1), VW PV1210, Toyota TSH1552. HOT LIGHT FASTNESS/HOT LIGHT AGING AND SUN SIMULATION SGS provides several weathering testing equipment: • Weatherometer, fadeometer, sunshine weatherometer, sunshine simulation with xenon arc lamps (hot temperature, aspersion and freeze) • Fluorescent lamp (UV-A, UV-B with temperature and humidity conditions)
