GMW 14162 Artificial Weather Color Fastness

The GMW 14162 standard, developed by the General Motors company, describes test methods for detecting the effects of weather conditions using a xenon arc lamp source (artificial sunlight) to simulate the extreme environmental conditions encountered inside a vehicle with the effect of sunlight, heat and humidity. These test methods are used to assess color fastness as well as being an artificial aging method to assess deterioration.

Four possible exposure cycles are defined under this standard:

• Light and dark exposure cycle (at 100 degrees, 420 nm) (method A). The cycle here alternates between light and dark periods. This cycle is based on exposure condition three described in the ISO 105-B06 standard.
• Light exposure cycle only (100 degrees, 300 nm to 400 nm) (method B). This cycle is based on exposure condition three described in the ISO 105-B06 standard.
• Light exposure cycle only (115 degrees, 300 nm to 400 nm) (method C). This cycle is based on exposure condition number one described in the ISO 105-B06 standard.
• Light and dark exposure (at 89 degrees, 340 nm) (method D). This cycle alternates between light and dark periods. This cycle is based on exposure condition five described in the ISO 105-B06 standard. This method is also equivalent to the following standards developed by the Society of Automotive Engineers (SAE): SAE J1885, SAE J2412, and SAE J2413.

This test procedure was developed to establish a common method for assessing color fastness to artificial weathering. The test methods described are for testing textile materials to simulate extreme environmental conditions inside the vehicle.

In principle, nothing in this standard is a substitute for the legal regulations in force.

Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides color fastness testing services against artificial bad weather conditions, within the scope of GMW 14162 standard, with its trained and expert staff and advanced technological equipment.
