Renault 37-00-081H Passenger Compartment - Material and Component Emissions

The “Renault 37-00-081H Passenger compartment – ​​Material and component emissions” standard, developed by the French automobile company Renault, is designed to:

• Notify suppliers of lists of controlled substances in the passenger compartment and associated measurement methods
• Determine the requirements to be followed for emitted substances and odors
• Define the conditions for suppliers to declare material emissions to Renault

This standard covers all materials and parts located inside the vehicle (interior and luggage compartment) with a total weight greater than 100 grams. This standard focuses specifically on:

• Dashboard
• Seats (linings, foams), including armrests, storage compartments under the seats and shelves
• Interior trim parts including headliner, door panels, floor liners, hard floor, trunk floor
• Instrument panel insulators
• Polymer drop panels
• Background
• Luggage tray
• Decorative parts such as console, gear lever, bars (paint, chrome, wood, film)
• Body seals (gaskets, weather strips, skids)
• Ducts of air conditioning systems (all elements in direct contact with the air entering the cabin)

It can also be applied to pasty or liquid products such as:

• Sealing mastics
  • Adhesives
• Damping products
• Anti-corrosion wax in cavities
• Expanding sealant

The provisions of standard "Renault 00-10-415 Manufacture and supply of products - General requirements" are fully applicable to this standard, unless express written indications to the contrary are given. The provisions defined in the standards relevant to each of the relevant parts may be applied.

The requirements for volatile organic compounds are specified in this standard as follows:

• Materials: items to be checked and relevant measurement methods

The list of all compounds to be measured and all elements that must be presented in the test report is included in the annex of the standard (Annex 1).

Only original test reports from a Renault accredited laboratory are accepted.

Sampling protocols (sample preparation, conditions, storage time, etc.) by material family are available in the following Renault methods. However, the samples must be representative of vehicle parts:

• Plastics: Injected plates according to a standard process
• Reticulated polyurethane foam: A representative material of the final part
• Sandwich thickness at least 0,5 mm: Each layer of the sandwich must be analyzed
• Sandwich thickness up to 0,5 mm: The entire sandwich is analyzed
• Paint sealant for interior: The sealant should be previously baked according to the protocol recommended by the paint engineer.

Samples should be prepared as follows:

• Samples should be taken immediately after production
• Exactly 7 days after production, it should be ventilated in a place free from light, heat and all kinds of pollution (recommended temperature 20 degrees plus/minus 3 degrees, humidity rate 45 percent plus/minus 5 percent) on a suitable support.
• Outside the ventilation period and until analysis, it should be stored hermetically packaged in a heat-sealed bag or, by default, in aluminium foil.
• Tests should be performed between days 7 and 42 after production samples.

Tests must be carried out in laboratories accredited by Renault.

Methods for measuring the concentrations of these compounds are listed in the table titled “List of test methods used for VOCs.”

• Complete parts or function: items to be checked and relevant measurement methods

The main families of volatile organic compounds (VOCs) are: aldehydes, ketones, amines, nitrosamines, glycol ethers, phthalates, phenols, alcohols, esters, halogenated hydrocarbons and aromatic hydrocarbons BTEXS (benzene, toluene, ethylbenzene, xylene, and styrene) and total VOCs.

Testing is carried out on a complete part or a full function according to methods recognised by Renault (see table entitled List of test methods recognised by Renault for VOCs). The term full function refers to a batch of several parts that provide the same service (e.g., boot lining with right and left linings, floor lining with front and rear linings).

The parts must be representative of what will equip the final vehicle. Additionally, the parts must be prepared as follows:

• -Must be taken immediately after production
• Exactly 7 days after production, it should be ventilated in a place without light, heat and any pollution (recommended temperature 20 degrees plus/minus 3 degrees, humidity rate 45 percent) on a suitable support.
• Outside the ventilation period and until analysis, it should be stored hermetically packaged in a heat-sealed bag or, by default, in aluminium foil.
• Tests should be performed between days 7 and 42 after production samples.

These parts must then be forwarded to Renault-accredited laboratories, which will perform the analysis. Validation plans are consulted to determine the level of the parts to be analyzed. By default, the highest-selling level is selected.

Total VOC, formaldehyde, and odor emission levels for each trim material must meet the requirements shown in the table within the standard in µg/g. The term "material" refers to all materials used for passenger compartment functions, such as thermoplastics, sheet molding compound, fabrics, foam, natural leather, synthetic leather, wood, and paint.

Measurements are required for materials used outside the cabin (gaskets, weather strips, slides, wax, adhesives, PVC mastics).

The concentration limit levels for each family of compounds, as well as for the odor, are defined in the table provided within the standard for each part or function.

Our organization, which has been supporting businesses across all sectors for years through a wide range of testing, measurement, analysis, and evaluation activities, has a strong team of employees who closely follow global developments in science and technology and are constantly improving themselves. In this context, we also provide testing services in accordance with the "Renault 37-00-081H Passenger compartment - Material and component emissions" standard.
