Ford BZ 108-01: 10-L Bag Method for Measuring VOC Emissions from Vehicle Interior Materials

The “Ford BZ 108-01 10-liter bag method for measuring VOC emissions from vehicle interior materials” standard, developed by Ford Motor Company (Ford), describes a material-level screening method for emissions of selected volatile organic compounds (VOCs) and total volatile organic compounds (TVOCs).

The Ford BZ 108-01 standard includes a test procedure used to assess volatile organic compound (VOC) emissions from automotive interior materials. This standard uses a 10-liter sampling bag method to measure both individual VOCs and total VOCs released from materials used in vehicle cabins.

As vehicle manufacturers place increasing emphasis on cabin air quality, passenger comfort, and regulatory compliance, this standard serves as a crucial screening tool to assess emissions from non-metallic interior components before they are approved for production.

The primary purpose of the Ford BZ 108-01 standard is as follows:

• To measure volatile organic compound emissions from automotive interior materials.
• Screening materials in product development and supplier qualification processes.
• Controlling cabin air quality by limiting the release of potentially harmful or odorous compounds.
• Supporting compliance with Ford material specifications and environmental requirements.

This standard applies especially to the following materials:

• Plastics
• Textile
• Carpets
• foams
• Adhesives
• Leather and synthetic leather
• Flooring components and interior fittings

In applying the described test method, a representative sample of the material is placed inside a 10-liter inert sampling bag under controlled environmental conditions. During conditioning, volatile organic compounds emitted by the material accumulate in the bag's atmosphere. The collected air is then analyzed using laboratory techniques such as thermal desorption and gas chromatography-mass spectrometry (GC-MS) to identify and quantify the emitted compounds.

This test provides the following:

• Concentrations of individual volatile organic compound species
• Total volatile organic compound values
• Comparative emission performance among materials.

This method can be used to evaluate compounds such as those listed below:

• Toluene
• Xylene
• Ethylbenzene
• styrene
• aldehydes
• ketones
• Other volatile organic compounds released from polymers, coatings, and adhesives.

The specific compounds reported depend on Ford's material requirements and laboratory analytical protocols.

The Ford BZ 108-01 standard belongs to a broader family of automotive interior air quality testing methods. Similar procedures used by other manufacturers include:

• ISO 12219-2
• VDA 278
• GMW 15634
• NES M0402
• TSM 0508G

These standards share the common goal of reducing exposure to chemical emissions from vehicle interiors.

The advantages of the 10-liter bag method are as follows:

• Rapid material screening: This method allows for a relatively quick assessment of emission performance before full vehicle testing.
• Cost effectiveness: Compared to large environmental chambers, the 10-liter bag approach requires less equipment and shorter test setup times.
• Supplier quality control: Automotive suppliers can use this method to verify that materials meet Ford emission requirements prior to shipment.
• Early detection of problems: Materials with excessive volatile organic compound (VOC) emissions can be identified during the development phase, reducing the risk of costly redesigns later in the vehicle program.

The Ford BZ 108-01 standard is commonly used by the following industries:

• Automotive original equipment manufacturers
• First-tier suppliers
• Second-tier material manufacturers
• Testing laboratories
• Interior component developers
• Chemical and polymer manufacturers

Accredited automotive testing laboratories frequently use the Ford BZ 108-01 standard among their VOC emission testing capabilities.

The Ford BZ 108-01 standard is necessary because modern vehicles contain numerous polymer-based materials such as plastics, foams, adhesives, textiles, carpets, coatings, and sealants that can release volatile organic compounds into the passenger compartment. Failure to effectively control these emissions can lead to air quality, odor, and regulatory compliance issues in vehicle interiors. This standard is considered important for the following reasons:

• Maintaining cabin air quality: New vehicle interiors often contain hundreds of chemicals originating from interior materials. Some volatile organic compounds (VOCs) can accumulate inside the cabin, especially when vehicles are exposed to sunlight and high temperatures. This standard contributes to improving cabin air quality by helping to identify materials emitting excessive VOCs before they are approved for production.
• Reducing car odor: One of the most common customer complaints about new cars is the new car smell, largely caused by VOC emissions from interior components. Excessive emissions can create unpleasant odors and negatively impact perceived vehicle quality. This standard allows for the following:
  • To compare the materials objectively.
  • Choosing lower-emission alternatives.
  • Minimizing unwanted indoor odors.
• Ensuring consistent material quality: Automotive manufacturers source materials from numerous suppliers worldwide. This standard provides a testing method that enables all suppliers to assess VOC emissions using the same procedure.
• Supporting compliance with regulations: Many countries and regions have introduced guidelines or regulations regarding in-vehicle air quality and chemical emissions. This standard helps manufacturers identify potential compliance issues early in product development.
• Supporting environmental and sustainability goals: Many low-emission materials have been developed with environmental considerations in mind. By encouraging suppliers to reduce VOC emissions, Ford supports the following:
  • Cleaner material formulations.
  • Reducing the use of highly volatile chemicals.
  • Improving sustainability across the automotive supply chain.

In summary, the Ford BZ 108-01 standard incorporates a specific automotive testing method to determine volatile organic compound (VOC) emissions from vehicle interior materials using a 10-liter sampling bag. This standard provides an efficient screening technique to evaluate cabin air quality performance, support material adequacy, supplier approval, and vehicle development activities. As automotive manufacturers continue to focus on healthier and more comfortable vehicle interiors, the Ford BZ 108-01 standard remains a vital tool in controlling VOC emissions throughout the supply chain.
