Sound Familiar?

WHERE MATERIAL TESTING DELAYS USUALLY START

Material testing issues rarely come from bad data. They come from mismatched methods, missing accreditation, or assumptions made too early in the project.

A test runs successfully, then the OEM rejects the report because the exact method variant wasn’t accredited.

A late OEM requirement surfaces and triggers unexpected retesting that blows your timeline.

Turnaround takes weeks longer than promised because no one asked the right questions upfront.

You don’t find out there’s a problem until it’s already a delay, not a warning.

A different test path would’ve saved three weeks and a resubmission, but no one flagged it at quoting.

Conditioning requirements aren’t surfaced until samples arrive, stalling the start date entirely.

You request a quote from a lab and wait days, only to get a vague estimate with no method confirmation attached. At GPTesting, most quotes are returned within 1 business day, scoped to your exact methods.

Before You Book

COMMON QUESTIONS

An automotive material testing consultation is a technical discussion between your engineering or quality team and a testing laboratory to scope the right methods, confirm availability, and plan your testing timeline before samples are submitted. GPTesting is an independent materials testing lab in Harper Woods, Michigan, serving the automotive supply chain since 1971. The free 30-minute consultation covers method identification, accreditation verification where required, retest and rejection risk review, conditioning and timeline planning, and a custom quote within 1 business day. No purchase order or commitment required.
GPTesting tests a wide range of automotive materials, not just plastics. While the lab’s name reflects its roots, GPTesting regularly performs testing on foams, textiles, coatings, adhesives, rubber, composites, and other materials common throughout the automotive supply chain. If your project involves automotive material testing of any kind, the free consultation is the fastest way to find out what GPTesting can do for you, and how quickly.
Not every project requires accredited testing, and the difference is simpler than you might think.

It is not about quality — it is about scope: At GPTesting, every test is performed to the same rigorous standards, regardless of accreditation status. The only distinction is whether a given test method has been formally listed on our A2LA scope of accreditation (ISO/IEC 17025:2017, Certificate #79.01). The process, the precision, and the people behind the results are exactly the same.

When accredited testing is required: Accredited results are necessary when an OEM, customer, or specification explicitly calls for them. Common examples include:

  • PPAP submissions for automotive suppliers
  • Formal supplier qualification programs
  • Regulatory compliance documentation
  • Contractual requirements specifying accredited results
Not sure which you need? During your consultation, GPTesting will help you identify exactly what your project requires, so you’re never over-scoping or leaving gaps in your testing program.
GPTesting performs a broad range of automotive material testing for Tier I and Tier II suppliers, OEM-directed programs, industrial manufacturers, and specialty product companies. Test categories include mechanical properties (tensile, flexural, impact, hardness), thermal analysis (DSC, TGA, HDT, Vicat), flammability and burn testing (FMVSS 302, UL 94), weathering and UV exposure (Xenon arc, UV-B fluorescent), FT-IR spectroscopy and material identification, color and appearance, chemical resistance, dimensional analysis, and OEM-specific automotive material specifications from Ford, GM, Stellantis, and others. The free consultation identifies which methods apply to your project and clarifies what falls within the accredited scope vs. what can be run as general testing.
Most standard automotive material tests return formal reports within 1–3 business days after testing is completed. The full timeline depends on conditioning requirements (some tests require 40–88 hours before testing can begin), test complexity, and current lab volume. GPTesting provides a realistic timeline estimate during the free consultation so you can plan around your program milestones. Rush and expedited options are available for time-sensitive projects at an additional cost. Mention your deadline on the call.
Bring any specification documents, OEM method IDs, PPAP requirements, sample photos, target dates, and known shipping constraints. A draft test plan or a previous test report with method references is especially helpful for scoping. If you’re unsure what’s needed, that is what the consultation is for. GPTesting’s technical team will help identify the right methods and flag anything that could cause a delay or rejection before samples are ever shipped.
Yes. Rush testing and prioritized report turnaround are available for an additional cost. Expedited options depend on current lab capacity and the conditioning requirements of your specific methods. Some tests have fixed conditioning windows that can’t be shortened regardless of priority. Mention your deadline during the free consultation and GPTesting’s team will tell you exactly what’s achievable.
GPTesting is located at 20450 Harper Avenue in Harper Woods, Michigan — part of the greater Detroit metropolitan area. The lab accepts samples shipped from anywhere in the United States, Canada, and internationally. Most clients ship samples via FedEx, UPS, or freight depending on quantity. During the free material testing consultation, GPTesting will confirm the best shipping method for your project and provide a shipping address. Results are delivered as formal PDF reports regardless of where samples originate.
Yes, completely free, no obligation, no purchase order required. A formal written quote follows within 1 business day for most standard projects. GPTesting offers the free consultation because a well-scoped project means faster turnaround, fewer surprises, and better outcomes for everyone. New customers are also welcome to ask about a 10% first-invoice discount when they book the call.
