Chemical resistance testing evaluates the resistance of materials to chemical media. In automotive applications, materials come into contact with various fluids \u2013 from cleaning agents and fuels to bodily fluids. <\/p>\n
Samples are exposed to various test media for defined periods at elevated temperature:<\/p>\n
\u2022 Application method:<\/strong> Drop application, immersion, or cotton swab contact Evaluation:<\/strong> Gloss change, color change \u0394E*, swelling, softening, cracking, surface alteration.<\/p>\n The following table shows all OEM-specific standards for chemical resistance covered by ASO Laboratory:<\/p>\n Typical test media in the automotive sector: sunscreen, insect spray, hand cream, disinfectant, fuel (gasoline, diesel), brake fluid, antifreeze, engine oil, and various cleaning agents.<\/p>\n According to defined criteria: gloss change (ISO 2813), color difference \u0394E* (CIE Lab), softening (Shore hardness), swelling (mass increase), cracking, and visual evaluation on a grading scale.<\/p>\n Vehicle surfaces come into daily contact with aggressive substances: sunscreen on steering wheels and gear knobs, cleaning agents during vehicle cleaning, body perspiration on seats. Material failure leads to complaints and warranty claims. <\/p>\n ASO Laboratory performs chemical resistance testing according to all common OEM standards. Our DAkkS accreditation to DIN EN ISO\/IEC 17025 guarantees standards-compliant results. <\/p>\n Contact us<\/strong> for a quote \u2013 we will advise you on optimal sample planning and test scope.<\/p>\n","protected":false},"excerpt":{"rendered":" What is Chemical Resistance?
