The “PSA B62 0030 Thermoplastics, thermoset materials, thermoplastic elastomers and rubbers - Specifications” standard, developed by PSA, a French multinational automotive company, describes material requirements in the form of a code. This standard applies to thermoplastic and thermoset materials, thermoplastic elastomers, and rubbers. These materials can be rigid or flexible, solid or low-density, reinforced or unreinforced. Cellular materials, yarns, and fibers are subject to specific norms. This standard does not include the chemical composition of the materials.
Material-specific functional requirements are coded according to 5 main criteria:
This coding is then completed according to specific criteria.
In terms of heavy metal compliance, any material must meet the PSA B20 0250 standard, which requires mandatory compliance with regard to heavy metals for all products and parts applied to and mounted on the vehicle.
The criterion for exposure to light or chemical medium is coded as follows:
The heat exposure criterion is coded as follows:
The impact properties of materials are related to the type of fracture (brittle or ductile) at a given temperature. For legal or standard requirements, the impact response criterion is codified as follows:
Ductility specifications are provided only for materials used in parts that must meet legal or standard requirements at a specific temperature. Ductility specifications should not be confused with impact resistance requirements, which must be defined in the functional requirements of the part.
The surface coating criterion is coded as follows:
When surface coating is required, the coating requirement must be specified in the technical specifications. “Others” encompasses various surface coating processes: chrome plating, hot foiling, vacuum metallic coating, varnishing, co-extruded surface coating, etc.
The criterion for exposure to ambient air is coded as follows:
In addition to the main criteria, specific criteria can also complement the specifications. These are coded as follows:
In the complex world of automotive manufacturing, material selection is paramount in ensuring vehicle safety, durability, and performance. The PSA B62 0030 standard addresses the increasing complexity of modern automobiles, where plastics and elastomers are an integral part of everything from interior trim and gaskets to under-hood components. By defining precise coding systems and test protocols, this standard ensures materials can withstand extreme conditions such as heat, chemicals, and mechanical stress, while also complying with global regulations regarding heavy metals and recyclability.
The PSA B62 0030 standard essentially establishes a coding system for material identification. This alphanumeric code summarizes critical attributes, allowing engineers to quickly assess suitability for specific applications. The code is broken down as follows:
Materials must pass the following tests in order to receive approval:
If there are any discrepancies in any area, the application will be rejected, and a detailed fault analysis will be required for resubmission.
The PSA B62 0030 standard is widely used in PSA vehicle manufacturing and affects the following components:
For many years, our organization, with its competent and experienced staff, has been understanding the needs of its clients, providing the advanced testing services they require, and assisting them in the establishment, implementation, and improvement of management systems. Within this framework, we also provide testing services compliant with the PSA B62 0030 standard.
