How BMW's inclusion of Brain of Materials in its process for HC emissions and odour data enables suppliers to build BMW-compliant test plans, commission qualified testing institutes, verify VOC and odour results against BMW limit values, and generate the expected result documents – in one continuous digital process.
BMW has included Brain of Materials in its process for securing HC emissions and odour data. Suppliers can now map the previously heavily manual sequence – from determining the relevant testing requirements, through commissioning qualified testing laboratories, to preparing and submitting the results to BMW – as a fully digital process.
In BMW's current information on HC emission measurements of materials and components, Brain of Materials is listed in the overview of the BMW-qualified process.
What this means in practice:
One boundary matters and is stated plainly: Brain of Materials does not carry out these tests itself. On behalf of the component supplier, the semi-finished product supplier or the raw material supplier, the platform takes over the digital control, processing and documentation of the required specifications and test data – connecting suppliers, qualified testing laboratories and the OEM in one continuous digital process.
Emission and odour behaviour is not assessed at vehicle level alone – it is built up from the contribution of every single material and component. To evaluate that contribution to the VOC emissions and the odour of the vehicle as a whole, BMW requires testing by appropriately qualified external testing institutes.
BMW's current information provides that emissions testing is commissioned at a testing institute that is accredited in accordance with ISO 17025 and qualified for the respective BMW test methods. Both conditions apply together: accreditation alone is not sufficient, and method qualification alone is not sufficient either.
For the supplier, this turns a laboratory decision into an approval decision. A test placed with an institute that does not meet both criteria produces data that cannot be used in the BMW approval chain – regardless of how technically sound the measurement itself may be.
BMW HC emissions and odour testing is the qualified determination of hydrocarbon emissions and odour behaviour of materials, semi-finished products and components, carried out by external testing institutes and evaluated against BMW's delivery specifications so that the contribution of each part to the emission and odour profile of the complete vehicle can be assessed.
The methods used sit within a family of OEM and industry procedures rather than within a single standard. BMW describes the process from test commissioning through to the feedback of test results, taking into account, among others, BMW GS 97014-2, GS 97014-3 and GS 97014-4, VDA 278, VDA 270, and BMW AA-0061
In scope are materials, semi-finished products and components whose emission and odour behaviour contributes measurably to the vehicle as a whole – supplied by raw material manufacturers, semi-finished product manufacturers and component suppliers along the approval chain.
The testing scope combines emission measurement and odour assessment. Which of the listed procedures applies, in which combination and with which acceptance criteria, is not a free choice – it follows from the applicable BMW delivery specification and the product in question. Determining that scope correctly is the first, and most error-prone, step of the entire process.
A written requirement is not the same as an executable test instruction. A reference to a test procedure alone leaves open which specimen preparation applies, what sample quantity is required, how the specimen is stored and transported before testing, which characteristic value is decisive for the assessment, and which limit value applies to the product version actually being supplied.
Each of these open points is resolved today by an iterative clarification cycle – supplier to laboratory, laboratory to supplier, supplier to OEM. The friction is structural, not accidental:
The consequence chain is short and expensive. An incorrect testing scope means the wrong measurement. A laboratory that is not qualified for the respective BMW test method means data that cannot be used. In both cases, the consequence is repeat testing, delayed sampling, and missed PPF / PPAP milestones.
The starting point of the digital process is the specification itself, held as data rather than as text. A digital specification, in the Brain of Materials sense, is much more than a digitised PDF. It is a semantically complete, machine-readable description of every relevant testing requirement, parameter and condition – encoded in a way that can be processed automatically across systems, suppliers and OEMs without interpretative leeway.
The distinction is not cosmetic: a scanned document still requires a human being to read, interpret and transfer it, while a structured specification can be evaluated by a system. Brain of Materials maintains the widest range of digital delivery specifications available on the market and applies the same principle to the requirements relevant to HC emissions and odour.
Every individual testing requirement is addressed through one identifier. The TestID (TID) is a unique, machine-readable identifier developed and maintained by Brain of Materials. It encodes the applicable test methodology, all relevant parameters (specimen geometry, strain rate, temperature, conditioning), acceptance criteria and result structures, as well as references to the underlying specification and product version.
Applied to emissions and odour, the TestID removes exactly the questions that generate clarification cycles today. Supplier, laboratory and OEM no longer discuss what was meant by a requirement – they reference the same identifier, and the parameterisation travels with it.
Once specifications are structured, the applicable scope of testing can be derived instead of researched. The platform resolves which requirements apply to a given material, semi-finished product or component, and assembles them into a requirement plan that is complete, traceable and free of interpretation.
For technical decision-makers, this means that the testing scope is derived from the specification rather than reconstructed from documents. For management decision-makers, it means accelerated approval timelines, reduced coordination costs, lower risk of rework – with up to 45 % efficiency gains in the initial digitalisation phase.
Test orders are placed from within the same environment in which the test plan was built. Brain of Materials operates a network of over 50 accredited testing laboratories that can be addressed directly from the platform; laboratory participation in the network is free of charge for the laboratories themselves.
For the BMW process, the selection is narrowed accordingly: enquiries are directed to suitable, BMW-accepted testing institutes, in line with BMW's requirement for ISO 17025 accreditation and qualification for the respective BMW test methods. The sequence is short and repeatable:
The effect is a time contrast rather than a marginal improvement: from weeks of manual coordination to a structured digital process, eliminating media discontinuities between supplier, laboratory, and OEM.
Results do not arrive as an attachment to be processed by hand. The results generated by the laboratories are fed back digitally and assigned in structured form to the respective material, semi-finished product or component. Brain of Materials processes this data and generates from it the documents and templates required for further communication with BMW.
That closes the gap where most of the manual effort sits today. Test data no longer has to be transferred manually several times or converted into different formats between OEM specifications, laboratory reports, result files and BMW documentation.
The most valuable check is the one that happens before submission. Suppliers can evaluate their VOC and odour results on Brain of Materials against the relevant OEM delivery specifications and limit values while the data is still in their own hands
Beyond the pass/fail view, results can be compared at the push of a button with other materials, raw materials, semi-finished products or components in the supplier's own portfolio. Deviations become visible early and can be assessed before formal submission – rather than after a rejection has already cost a sampling milestone.
Existing test data does not have to be left behind in PDF and Excel archives. Brain of Materials applies a hybrid methodology combining AI-based text and structural analysis, algorithmic mapping of extracted data elements, systematic TestID assignment, and domain-specific validation through continuous feedback loops with Brain of Materials subject matter experts.
Converted historical results become usable again – as evidence, as a comparison basis for new measurements, and as the starting point for benchmarking within the portfolio.
Emission and odour behaviour is decided at material level long before a component exists. Structured results allow formulations to be compared against one another and against BMW limit values across the portfolio, so that unsuitable candidates are identified before they enter a component development programme.
Tier suppliers carry the coordination burden between OEM requirements, sub-suppliers and laboratories. A structured requirement plan, direct commissioning and automatically generated BMW documents remove a substantial share of that coordination overhead – and make the approval status of each part visible at any point in time.
Laboratories receive unambiguous, TestID-referenced orders instead of free-text requests that require clarification before work can start. Result delivery is structured rather than document-based, which reduces query volume on both sides.
BMW has taken Brain of Materials into its process for securing HC emissions and odour data. In BMW's current information on HC emission measurements of materials and components, Brain of Materials is listed in the overview of the BMW-qualified process. Suppliers can therefore organise the sequence from testing requirement to result submission digitally rather than manually.
No. Brain of Materials does not perform testing. On behalf of the component supplier, the semi-finished product supplier or the raw material supplier, the platform handles the digital control, processing and documentation of the required specifications and test data, and connects suppliers, qualified testing laboratories and the OEM within one continuous digital process.
BMW describes the process from test commissioning through to result feedback and takes into account, among others, BMW GS 97014-2, GS 97014-3 and GS 97014-4, VDA 278, VDA 270, and BMW AA-0061. Which procedures apply to a specific material or component follows from the applicable BMW delivery specification rather than from free selection by the supplier.
BMW's current information provides that emissions testing is commissioned at a testing institute accredited in accordance with ISO 17025 and qualified for the respective BMW test methods. Within the platform, enquiries are directed to suitable and BMW-accepted testing laboratories, so that the qualification question is resolved before the order is placed rather than afterwards.
Results generated by the laboratories are fed back digitally and assigned in structured form to the respective material, semi-finished product or component. They are mapped to the TestIDs used in the test plan, which makes them directly comparable, reusable for benchmarking, and available for downstream systems without manual re-entry.
Yes. Before submission, suppliers can evaluate their VOC and odour results against the relevant OEM delivery specifications and limit values within the platform. Results can additionally be compared with other materials, raw materials, semi-finished products or components in the supplier's own portfolio, so that deviations become visible before formal submission.
Brain of Materials processes the returned test data and generates from it the result documents and templates expected by BMW for further communication. This removes the manual assembly of documentation from laboratory reports and result files, and with it a frequent source of transfer errors and version confusion.
Manufacturers of raw materials, semi-finished products and components can organise their BMW-relevant HC emissions and odour testing digitally. The platform acts on behalf of the respective supplier, which means the same structured process is available to a raw material producer, a semi-finished product manufacturer and a Tier component supplier.
Legacy data is converted using a hybrid methodology combining AI-based text and structural analysis, algorithmic mapping of extracted data elements, systematic TestID assignment, and domain-specific validation through continuous feedback loops with Brain of Materials subject matter experts. Converted results become available for comparison, benchmarking and evidence purposes alongside newly generated data.
Brain of Materials is an active participant in the development of VDA 231-301, the recommendation of the Verband der Automobilindustrie for the standardised, machine-readable exchange of material test data. Within this framework, the TestID functions as a BusinessKey that enhances the data model with unambiguous references – bridging the gap between normative text and operational testing practice.
With its inclusion in the BMW process for HC emissions and odour data, Brain of Materials extends its role as the operational infrastructure between OEM requirements, suppliers and qualified testing laboratories. The capabilities available to suppliers are:
The outcome is measurable rather than atmospheric: less manual effort, fewer media discontinuities, higher data transparency, and materially faster material and component approvals – supported by TISAX-certified and ISO 9001-compliant data handling throughout. The same principles already underpin the platform's support for BMW GS 93016 approval.
