of Testing Equipment
ISO/IEC 17025 · ASTM E4 / ISO 7500-1 · ASTM E1012 · NADCAP
Calibration, force-measurement, frame-alignment and NADCAP certification for TensileMill CNC and third-party testing equipment.
Scope of Accreditation
In material testing, particularly tensile testing, consistent and reliable results depend on calibrated equipment and well-defined procedures. TensileMill CNC collaborates with ISO 17025 accredited calibration labs to certify testing machines, load cells, extensometers and specimen preparation equipment according to recognized industry standards. Our certification support covers ASTM, ISO and related frameworks, including projects that require compliance for aerospace, automotive and general industrial applications.
Certification is performed using accepted technical protocols such as ASTM E4 and ISO 7500-1 for force verification, ASTM E1012 for frame alignment, ASTM E83 and ISO 9513 for extensometer calibration, as well as ASTM E8 and ISO 6892-1 for tensile testing of metals. These standards define the preparation of specimens, the loading rate used during testing and the format of recorded results. This allows data to be reproduced across different facilities and accepted by customers, auditors and regulatory bodies.
Beyond calibration and method-based testing, we also support accreditation under ISO/IEC 17025:2017. This framework outlines how laboratories manage quality systems, maintain measurement traceability, evaluate uncertainty and demonstrate technical competence, which is critical when certifying results for external review.
Whether you operate TensileMill CNC machines or equipment from another manufacturer, we coordinate the full certification process and provide traceable documentation through our accredited partners. If certification is required for an upcoming audit or project, you can submit a request and our team will guide you through the next steps.
ISO/IEC 17025:2017 Certification
TensileMill CNC works directly with ISO 17025 accredited calibration providers to help testing facilities meet ISO/IEC 17025:2017 requirements. The standard outlines how a laboratory must demonstrate technical capability, maintain measurement traceability, document uncertainty, and operate under a controlled quality system, all of which form the foundation for credible test results.
We coordinate ISO 17025-compliant calibration and certification for tensile testers, load cells, extensometers, and alignment verification equipment, regardless of whether the system was supplied by TensileMill CNC or another manufacturer. Clients receive calibration reports and documentation that meet the expectations of auditors, customers, and internal quality teams.
Our process follows the same accreditation scope used by ISO 17025 laboratories such as Cal-Rite, giving facilities access to valid, traceable certification packages for audits, equipment validation, or onboarding of new machines. If your facility is preparing for compliance, we can connect you with the appropriate accreditation pathway and manage the certification workflow on your behalf.
ASTM E4 / ISO 7500-1 Force-Measurement Certification
If you test force-measurement equipment and need certification according to ASTM E4 (Class A) or ISO 7500-1 (Class 0.5 or 1), we handle the full process, whether the system came from us or from a third-party supplier.
These standards set out how a testing machine’s force-measuring system must perform. For example, ISO 7500-1 defines calibration and verification of static uniaxial testing machines, specifying that calibration must cover the full operating range, and that the machine must meet the assigned accuracy class after a general inspection and force-proving verification.
ASTM E4 describes accepted procedures for verifying force-measuring systems in both tension and compression machines, requiring that indicated force values stay within ±1 % of the applied load across the verified range and that repeatability meets strict criteria.
Our certified process includes multi-point calibration: applying known reference forces at various levels (from low loads up to full capacity), checking the machine’s responsiveness in both increasing and decreasing load cycles, and assessing repeatability and reversibility. After calibration, we issue traceable documentation that records actual performance, error margins, and measurement uncertainty, documentation that auditors, customers, or regulatory bodies will accept without questions.
With this certification in place, universal testing machines, load frames, force sensors or load cells operated in metallurgical, aerospace, automotive or industrial labs produce data you can rely on. This minimizes risk of challenge or data rejection during contract reviews, quality audits or certification procedures.
Request certification to start: we coordinate with our ISO 17025-accredited partners, manage all logistics, and deliver a full compliance report with your equipment.
ASTM E1012 / ASTM E2309 / ASTM E2658 – Frame Alignment & Displacement-Verification Certification
If your lab needs to verify alignment or displacement-measurement systems for tensile, compression, or fatigue testing, we can help. We support calibration and certification not only for equipment supplied by TensileMill CNC, but also for third-party machines and accessories under these standards.
- ASTM E1012 deals with alignment verification of testing frames. It requires use of a strain-gauged alignment specimen to check if the applied load is truly axial, without unintended bending or eccentricity. This is particularly important when precision counts, as misalignment can skew tensile or compression results.
- ASTM E2309 governs calibration of displacement-measuring devices (such as cable-extension transducers or digital indicators) used in material testing machines, ensuring accurate displacement data during tests.
- ASTM E2658 covers verification of the machine’s speed or displacement-measuring system (when using cable-extension + time-based displacement), confirming that indicated displacement vs. actual matches within defined tolerances.
These checks – frame alignment, calibration of displacement sensors, displacement-vs-time verification – help labs maintain measurement integrity. With properly aligned frames and calibrated displacement systems, test results are more reliable, repeatable, and defensible during audits or third-party reviews.
We coordinate the full certification cycle via ISO-accredited partners: setup, calibration, verification, documentation. If you need to equip a lab or bring existing equipment into compliance, request certification and we’ll manage the process end to end.
UL Certification for U.S. Compliance and Equipment Approval
When tensile testing machines are installed in the United States, electrical and safety conformity is commonly evaluated according to UL standards. UL certification confirms that equipment has undergone independent safety review through an OSHA-recognized NRTL and is accepted by inspectors and facility engineers responsible for commissioning. This makes UL compliance an important step for laboratories, manufacturers, and research centers planning to operate tensile systems within U.S. regulatory environments.
TensileMill CNC can supply tensile testing machines and supporting equipment in UL-certified configurations upon request. Certification may include review of electrical architecture, wiring and grounding methods, operator safety controls, labeling, and panel design to confirm that the system meets UL requirements and aligns with local electrical codes. This helps reduce installation delays and streamlines approval during facility inspections and commissioning.
If your project specifications, customers, or internal quality policy require UL Listed or UL Recognized equipment, we can help initiate certification for both newly purchased machines and third-party systems already in use. Request certification to begin the UL approval process, or contact our team for guidance on U.S. compliance requirements for tensile testing equipment.
CSA-Certified Systems for the Canadian Testing Market
Operating a tensile testing facility in Canada typically requires equipment that is approved under CSA safety and electrical regulations. TensileMill CNC offers testing systems that can be supplied with CSA certification, verifying that the equipment has been reviewed and qualified through independent safety evaluation to meet Canadian compliance expectations. This leads to smoother installation, faster commissioning, and better acceptance during inspections or facility audits.
For Canadian clients, CSA certification is available for tensile testing machines, force measurement frames, extensometer-ready systems, electrical panels, and integrated safety controls. Customers who require documentation for internal validation or regulatory verification receive full certification paperwork alongside their machine, supporting readiness for quality reviews and audit conditions.
International laboratories with Canadian compliance requirements can also obtain CSA-certified equipment upon request, including certification for new systems or for existing third-party tensile machines that require approval before operation. Request certification to begin the process, or contact our team if you need support selecting the appropriate CSA compliance path.
NADCAP Accreditation for Aerospace and Defense Testing
NADCAP is an accreditation system for critical processes used in aerospace, defense, and related industries. The program is managed by the Performance Review Institute (PRI) with oversight from major OEMs, suppliers, and regulatory representatives. NADCAP accreditation is widely recognized across the global aerospace sector and is often required for participation in approved supply chains.
The program covers key special processes such as mechanical and materials testing, heat treatment, coatings, non-destructive examination, and other controlled procedures.
What NADCAP Accreditation Provides
NADCAP reduces audit workload by replacing multiple customer audits with one unified review. This cuts waiting time, frees staff, and lowers the cost of compliance.
Accreditation gives confidence to OEMs, contractors, and auditors. It shows that equipment, procedures, and personnel follow aerospace-level requirements.
Standardized quality procedures and controlled documentation help maintain stable test results, avoid nonconformities, and simplify future inspections.
In aerospace and defense programs NADCAP is often mandatory. Accredited suppliers receive access to contracts that are closed to non-approved facilities, strengthening their position in the supply chain.
How NADCAP Audit Works Step by Step
The accreditation process follows a structured sequence. Each stage confirms that equipment, procedures, documentation, and personnel meet aerospace-level quality expectations. Below is a simplified step-by-step overview of how a typical audit progresses:
Step 1: Registration and Application
Companies submit a request to PRI and select the scope of accreditation, such as Materials Testing Laboratory (MTL) or other special process categories.
Step 2: Audit Scheduling and Preparation
A qualified auditor is assigned, and the facility performs an internal readiness review. Documentation, calibration records, quality procedures, and traceability systems must be checked in advance.
Step 3: On-Site Audit
The auditor evaluates equipment setup, operator qualification, process control, documentation practices, calibration certificates, and quality-management execution.
Step 4: Corrective Actions if Required
Any non-conformance identified during the audit must be corrected and documented. Evidence of corrective action is reviewed before the process moves forward.
Step 5: Review and Certification Decision
A PRI task group reviews the audit report and issues a certification decision based on compliance level and submitted evidence.
Step 6: Ongoing Surveillance
Periodic follow-up audits and monitoring are required to keep accreditation active and demonstrate continuous adherence to NADCAP expectations.
Industries and Processes Recognized Under NADCAP
NADCAP applies to processes that require controlled testing, traceability and consistent results. The program is used in:
- materials and mechanical testing
- non-destructive examination
- heat treatment and coatings
- welding and fabrication work
- chemical processing and metallurgy
- additive and precision manufacturing
What NADCAP Certification Means for Suppliers
Accredited suppliers operate under standardized quality controls, maintain traceable calibration records and pass a single unified audit accepted across OEM chains. For many aerospace and defense contracts NADCAP approval is a requirement, not an option.
Accreditation reduces repeated customer audits, lowers internal compliance cost and improves acceptance of test data. It also provides access to programs closed to non-approved labs and strengthens supplier credibility during procurement evaluations.

What is ISO 17025?
ISO 17025 is the international standard for the competence of testing and calibration laboratories. When a lab is ISO 17025 accredited, it has demonstrated that its methods, equipment, and staff produce reliable, traceable measurements.
Accreditation is what gives a calibration certificate its weight. Learn more about our tensile testing equipment.
What do ASTM E4 and ISO 7500-1 verify?
Both standards define how the force accuracy of a testing machine is verified against traceable references and then classified. In practice, a calibration lab applies known forces and confirms the machine reads them within the allowed tolerance.
Verified force is the basis of every valid strength result. See how it fits our tensile testing equipment.
What does ISO 7500-1 class 1 versus class 0.5 mean?
The class describes how tightly the machine's force reading must match the applied reference force. Class 1 allows up to one percent error, while Class 0.5 is twice as strict at half a percent, suited to more demanding work.
The class you need depends on your specifications. To match a class to your work, request a personal quote.
How often should a testing machine be calibrated?
Most labs calibrate their testing machines at least once a year, and more often for heavy use, after a move, or when a standard or customer requires it. Regular calibration keeps the machine inside its accuracy class between checks.
A consistent schedule keeps you audit-ready. To plan calibration, talk to a specialist.
Why is calibration important?
Calibration confirms that the force, and often the extension, your machine reports are accurate and traceable. Without it, results can drift out of tolerance, putting both compliance and product decisions at risk.
Traceable calibration is the foundation of credible data. Learn more about our standards and certification.
What is NADCAP?
NADCAP is an industry-managed accreditation program for special processes in aerospace and defense, including materials testing. Suppliers to those industries are often required to hold NADCAP accreditation for their testing and related processes.
If you serve aerospace, NADCAP may drive your requirements. To discuss compliance, talk to a specialist.
