Daimler DBL 5307 Flame Retardant Properties, Interior Trim Parts, Requirements and Test Specifications

The DBL 5307 standard published by the Daimler automobile company describes the requirements for the flame retardant properties of interior trim parts and defines test methods.

The DBL 5307 standard mainly consists of the following parts:

• The DBL 5307.10 standard covers all interior materials of passenger cars, multi-purpose passenger cars, trucks and buses. For buses with more than 22 seats, seat accessories, side and rear panel coverings, materials with thermal or acoustic function, floor coverings, luggage racks, heating and ventilation hoses, floor panels, lighting systems are included.
• The DBL 5307.11 standard covers as product version 10, however, the danger of incompatibility due to aging as a result of thermal stress.
• The DBL 5307.12 standard, as product version 10, covers the situation where there is a danger of incompatibility due to aging as a result of thermal stress due to moisture.
• The DBL 5307.13 standard covers as product version 10, however, the danger of incompatibility due to aging as a result of slight thermal stress.
• The DBL 5307.20 standard covers interior trim materials on the vehicle roof in buses with more than 22 seats.
• The DBL 5307.21 standard covers curtains or roller blinds on buses with more than 22 seats.
• The DBL 5307.22 standard covers electrical conductors in buses with more than 22 seats.
• The DBL 5307.40 standard covers textile tarps and the like, for example for fire engines, rescue vehicles and similar special vehicles.
• The DBL 5307.41 standard covers water treatment conditions for products defined in the DBL 5307.40 standard, only if there is a danger of non-compliance due to aging.
• The DBL 5307.45 standard covers coated tarpaulins and nets for special vehicles.

This standard describes the requirements and test methods for the flame retardant properties of materials and fabrics used in the driver's cabin, passenger compartment and all adjacent areas of motor vehicles and buses. The purpose of this standard is to evaluate a fire load to prevent a fire from developing or to allow a fire to spread very slowly.

This standard covers all materials used in the passenger compartment in the form of fiber materials, coatings, adhesives, foams, compressed materials, impregnations, panels, leather, deep drawn and injection molded components, such as thermoplastics, thermoset plastics, elastomers and combinations thereof.

In addition, the following components must meet the criteria listed in this standard: seat cushions, backrests, seat belts, headliner, sunroofs, armrests, all floor panels, including door, front, rear and side panels, bulkheads, headrests, floor coverings , sun visors, curtains, sun visors, wheel hood covers, mattress covers and all other interior materials designed to absorb energy upon occupant contact in the event of a collision, including cushioning and impact-activated elements. Any material that does not adhere to other materials at each point of contact must meet the requirements when tested separately. Any material that adheres to other materials at each point of contact must meet the requirements when tested as composite with other materials.
