Ghesquiere Plastic Testing renews A2LA accreditation through 2027: ISO/IEC 17025:2017 mechanical testing you can build on

Let’s start with what we know. Ghesquiere Plastic Testing, Inc. in Harper Woods, Michigan has successfully renewed its A2LA Accreditation for ISO/IEC 17025:2017 compliance in mechanical testing. Our accreditation remains in effect through December 31, 2027 under A2LA Certificate No. 0079.01.

For current and prospective automotive clients, this is not a ceremonial badge. It’s independent confirmation that our testing work is performed under a globally recognized framework for technical competence and laboratory quality. In practical terms, it supports the outcomes you care about most: defensible data, fewer audit headaches, and decisions you can make without second-guessing the test report.

We are proud of the renewal. We’re also clear-eyed about what it represents: consistent performance under scrutiny, and the discipline to keep improving even when the schedule is tight and the stakes are high.

A2LA accreditation renewed through December 31, 2027

A2LA (American Association for Laboratory Accreditation) has renewed Ghesquiere Plastic Testing’s accreditation through December 31, 2027. The renewal confirms our conformance to ISO/IEC 17025:2017 for mechanical testing under Certificate No. 0079.01.

If you are a quality manager, engineering lead, or program owner in the automotive supply chain, you already know why this matters. OEM and Tier requirements do not just ask for “test results.” They ask for results produced under controlled methods, calibrated equipment, trained staff, traceable records, and a quality system that can be audited. This renewal verifies that those elements are in place, and working.

What A2LA accreditation and ISO/IEC 17025:2017 actually mean

The standard in plain terms: competence plus a working quality system

ISO/IEC 17025:2017 is the international standard for the competence of testing and calibration laboratories. It covers two essentials that automotive organizations care about:

• Technical competence: the lab can perform the test correctly, using suitable methods, validated processes, calibrated equipment, and trained personnel.
• Quality management: the lab controls documentation, records, data integrity, nonconforming work, corrective actions, and continual improvement so results are consistent and auditable.

In short, ISO/IEC 17025 is built to answer the question your customers and auditors will ask: “Can we trust this data, and can you prove it?”

Why ISO/IEC 17025 matters in the automotive supply chain

Automotive programs live on a timeline, and timelines live or die by decisions. Material selection, supplier approval, launch readiness, and corrective actions all depend on reliable test data. ISO/IEC 17025 matters because it reduces uncertainty at the decision point.

When your material test results are generated by an accredited laboratory, you are better positioned to:

• Support OEM and Tier customer requirements for accredited or third-party testing.
• Strengthen documentation packages for validations, submissions, and supplier reviews.
• Respond with confidence when test results are questioned during an audit or escalation.

How accredited results support audits, launches, and documentation

Accreditation does not replace your internal quality system. It complements it. An accredited report gives your team an external anchor: standardized practices, controlled records, and traceability that stand up when scrutiny increases.

That is useful during routine supplier management. It is even more useful when an issue becomes urgent, such as a launch window tightening, a customer raising a concern, or a spec interpretation turning contentious.

The renewal process: what is evaluated, and why it is rigorous

Accreditation renewal is earned, not assumed. A2LA evaluates laboratories against ISO/IEC 17025 requirements using assessments that are designed to be thorough and evidence-based.

Technical competence: methods, equipment, and traceability

Testing is only as strong as the chain behind it. Renewal includes review of how methods are selected, controlled, and executed, and how measurement systems are maintained. That includes calibration programs, traceability, equipment maintenance, and method controls that keep results consistent over time.

People and proficiency: training, supervision, and performance checks

Automotive testing is not “set it and forget it.” It requires technicians and analysts who understand the method, recognize anomalies, and follow documented procedures even when the schedule is unforgiving. Renewal evaluates competency, training, and proficiency practices that demonstrate the work is repeatable and dependable.

Quality management: records, controls, and corrective actions

ISO/IEC 17025 expects a laboratory to operate with strong process control: document management, record retention, review of results, handling of nonconforming work, and corrective actions that address root causes. That discipline is not paperwork for its own sake. It is how a lab protects your project from avoidable errors and delays.

Impartiality and consistency: confidence that results hold up under scrutiny

ISO/IEC 17025 also emphasizes impartiality and consistent operations. For clients, that translates to results you can treat as stable inputs to engineering decisions, not variables to argue about later.

Automotive testing excellence: accredited capabilities that match OEM reality

Our day-to-day work supports the practical needs of automotive suppliers: qualifying materials, verifying performance against specifications, investigating changes, and documenting compliance. We maintain accredited capabilities aligned with the kinds of methods and categories that show up in real validation plans.

Coverage across major OEM methods (select highlights)

Within our accredited scope, we support a wide range of automotive OEM and manufacturer test methods. That includes major method families used throughout the supply chain, such as:

• Ford test methods (FLTM).
• General Motors test methods (GMW and GM9000 series).
• Honda Engineering Standards (HES).
• Toyota methods (including BSDM and TSM series).
• Nissan Engineering Standards (NES).

We are selective here on purpose. The point is not to bury you in method numbers. The point is that our accredited capabilities map to the OEM ecosystem your teams work inside every day.

Mechanical and physical performance: tensile, tear, abrasion, hardness, impact

Mechanical testing is often the backbone of material approval, process change evaluation, and ongoing quality checks. Depending on the material and application, that can include tensile properties, tear resistance, abrasion performance, hardness, and impact-related behavior.

For automotive suppliers, these tests become decision tools. They help answer questions such as:

• Will this resin or compound meet the performance window in the spec?
• Did a supplier change or process shift alter key properties?
• Is the field issue consistent with a material performance change?

Weathering and aging: accelerated exposure and performance retention

Materials do not perform in a vacuum. UV, humidity, temperature cycling, and time can change appearance and properties. Weathering and aging evaluations help clients predict performance retention and reduce surprises once a part is in service.

Flammability: meeting interior and component safety expectations

Flammability testing remains a non-negotiable requirement for many interior and underhood materials. Automotive teams need fast, defensible answers here because flammability outcomes can halt approvals and delay shipments. Accredited testing helps keep these results credible, traceable, and easier to defend.

Chemical resistance: fluids, cleaners, and real-world contamination

Fuel, oil, coolants, cleaners, and incidental exposures can degrade polymers and elastomers. Chemical resistance testing helps validate that a material can handle the environments it will face, and it supports root-cause work when parts show unexpected change after exposure.

Thermal analysis and temperature performance: material behavior under heat and cold

Temperature is a constant variable in automotive performance. Thermal analysis and temperature-focused evaluations help characterize material behavior across conditions, supporting material selection and troubleshooting where heat history or operating temperature may be part of the story.

What this renewal means for you: practical client benefits and competitive advantage

Accreditation is not just about what a lab can do. It is about what you can do with the results. Our A2LA renewal helps clients in the automotive supply chain move faster with less risk.

Confidence you can document: results accepted and defensible

When you submit data to an OEM customer or a higher-tier organization, you want the discussion to be about engineering decisions, not whether the lab was credible. A2LA-accredited, ISO/IEC 17025:2017 compliant testing provides a recognized basis for confidence.

Fewer surprises in audits and supplier reviews

Audits reward consistency. Accreditation renewal signals that our competence and quality system have been independently evaluated and found to meet a standard used worldwide. That can help reduce the “prove it again” cycle that drains time during supplier reviews, launches, and escalations.

Less risk, less rework: catching issues earlier with reliable data

Bad data is expensive. It causes re-tests, reruns, delays, and sometimes incorrect decisions that ripple into tooling, production, and customer confidence. Accredited testing reduces the odds of those missteps by enforcing method control, traceability, and documented review.

Faster decisions: clear reports and direct access to experts

Speed matters, but speed without clarity is just motion. Our goal is to deliver both: responsive turnaround supported by reports that are easy to interpret and ready to file. When questions come up, you can speak directly with people who understand the method and the data.

Global credibility: smoother acceptance across organizations and locations

ISO/IEC 17025 is recognized internationally, and A2LA is a well-established accreditation body. For clients with multi-site operations, global customers, or cross-border supply chains, that recognition helps results travel farther with fewer obstacles.

Continuous improvement is the job, not the slogan

Renewing accreditation is a milestone. Maintaining it is the daily work. ISO/IEC 17025 is designed to keep laboratories honest by requiring continual attention to process performance and technical competence.

Maintaining ISO/IEC 17025:2017 day to day

Accreditation is sustained through a disciplined routine: controlled procedures, documented reviews, traceable calibrations, and systematic handling of nonconformities. It is not glamorous. It is effective.

Investing in equipment, calibration, and method control

Mechanical testing depends on the integrity of the measurement system. We maintain calibration and verification practices that keep instruments reliable and data defensible. When methods evolve or client needs shift, we control changes carefully so your historical comparisons remain meaningful.

Ongoing training and cross-checks that keep results consistent

People produce results. We keep competencies current through training, performance checks, and internal reviews that support repeatability and consistency across projects and timeframes.

Process discipline that protects your timeline

Automotive timelines do not care about excuses. Our quality system is built to reduce avoidable friction: fewer unclear handoffs, fewer preventable questions mid-test, and less chance of rework because something was not documented correctly the first time.

A partnership approach built for automotive timelines

Automotive clients do not need a lab that simply runs a method. They need a lab that understands the environment: last-minute engineering changes, shifting build schedules, unclear spec language, and the pressure of an external customer waiting for documentation.

How we support engineering and quality teams under deadline pressure

We are structured to be responsive and practical. That means clear scoping, fast answers on feasibility, and direct communication with people who can solve problems, not just route emails.

Working through unclear specs without slowing you down

OEM and customer specifications can be precise, and they can also be frustratingly vague. When requirements are unclear, we help clients interpret what is needed, confirm the correct method family, and define sample preparation and conditioning expectations. The goal is simple: reduce ambiguity early so you do not pay for it later.

Communication that stays concrete: scope, sample needs, and turnaround

Good testing starts before the first specimen is cut. We emphasize practical alignment at the start of the job:

• Clear definition of test scope and acceptance needs.
• Sample requirements, labeling, and conditioning expectations.
• Realistic turnaround commitments tied to your deadline.

This is the part most labs treat as administrative. In our experience, it is where projects are won or lost.

A note of thanks to the clients who trust our work

We appreciate the automotive clients who place their validation work, troubleshooting investigations, and compliance needs in our hands. Accreditation renewal reflects internal discipline, but it is also a response to client expectations. You keep the bar high. We intend to keep clearing it.

Looking ahead: ready for what the next program cycle requires

The automotive industry does not stand still, and neither do test expectations. Materials evolve, sustainability pressures change formulations, and OEM requirements continue to tighten. Our renewed accreditation positions us to keep serving as a stable, audit-ready testing partner through the next cycle of programs and launches.

Staying aligned with evolving OEM requirements and industry standards

We monitor method updates and industry expectations so the work you receive stays aligned with current requirements. When a method revision or customer requirement changes what “good” looks like, we adapt deliberately and document the change correctly.

Scaling support for new materials and tighter validation windows

Modern programs ask materials to do more, with less time to prove it. We focus on the fundamentals that help clients move with confidence: accurate results, controlled methods, and responsive communication that keeps your validation plan on track.

How to engage our team for your next validation or troubleshooting need

If you have a new program quote, a last-minute customer request, a material change, or a field issue that needs data quickly, we are ready to scope the work and get it moving. Let us know your deadline, and we will work backward from it.
