VW PV 1303 Non-Metallic Materials - Light Exposure Test of Passenger Compartment Components

The VW PV 1303 standard, developed by the Volkswagen automobile company, describes the requirements for testing planar fabrics, plastic parts, rubber parts, paints, leathers, decorative wood parts, as well as textile and film laminated components of vehicle interior trim, for color fastness and resistance to light and heat. . With the method described in this standard, parts exposed to light are evaluated for sample and standard production monitoring. During testing, samples are exposed to a filtered xenon arc lamp in the test device. The exposed samples are also used to determine residual tear strength, residual elongation at tear, and residual abrasion resistance.

For the purposes of this standard,

• In non-rotational mode, the samples and lightfastness scales are constantly facing the light source during testing, meaning there is no light-dark variation (rotational mode) during this test.
• During this test, the samples are not sprayed with water, ie dry exposure is applied.

In this standard, exposure to high temperature light is applied to non-metallic vehicle interior materials. The number of required periods is specified in the technical supply specification, depending on the location of the component. Additional testing may be required during interim checks and after completion of light exposure to evaluate the light fastness of the material (for example, brushing or the Martindale abrasion test).

Samples are irradiated subject to non-turning and dry exposure instrument conditions. High heat stress on equipment materials inside the vehicle is simultaneously taken into account (exposure to high temperature light). Each of the specified test conditions defines an exposure time. For this period, the DIN 75202 standard is taken into account (DIN 75202 Determination of color fastness of interior materials in motor vehicles - Xenon arc lamp test).

Xenon arc lamps produce light by passing electricity through ionized xenon gas at high pressure. Widely used in the daylight simulation industries, these lamps produce a bright white light that closely mimics natural sunlight.

Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides light exposure testing services for non-metallic materials, passenger compartment components, within the scope of VW PV 1303 standard, with its trained and expert staff and advanced technological equipment.
