Quality System & Standards
The standards, traceability and management arrangements that govern the work described on this site.
Overview
Calibration is performed under ISO/IEC 17025:2017 by accredited partner laboratories. Certificates are issued under the performing laboratory's accredited scope, with method, reference standard and reported uncertainty stated for each parameter checked.
Standards Referenced
Work described on this site is performed under ISO/IEC 17025:2017.
Accreditation named anywhere here is the performing laboratory's, and its limits are the limits of that laboratory's published scope. Measurements outside the scope are reported as non-accredited and identified on the certificate rather than quietly included. Each accreditation statement names the laboratory that holds it.
What is included with a quotation is explained on the accreditation documentation page.
Metrological Traceability
Measurements are traceable to the SI through NIST. Each certificate records the reference standards used and the measurement uncertainty reported for the specific parameter, whether that is volumetric length error on a CMM, flatness on a surface plate, or diameter on a ring gauge. Where a result falls outside the stated tolerance, the as-found value is reported alongside the as-left value if adjustment is authorized. Deviation findings are documented at the request review and result review stages of the quality system, consistent with the complaints-and-appeals process maintained alongside them.
The traceability statement belongs to the measurement, not to the building. On the certificate you will find the reference standard used, its calibration status at the time, and the chain by which it reaches the SI unit. Should that reference later fail its own calibration, the intervening work is reviewed and affected customers are contacted.
Equipment and Maintenance
Supported equipment includes bridge, gantry and cantilever coordinate measuring machines, portable articulated arms, granite surface plates, gage blocks, and ring and plug gauges. Requests are reviewed before a method is selected, so the laboratory assigned to a submission holds accredited scope matching the instrument type and the parameters requiring verification. If a customer disputes a reported result, a documented complaints-and-appeals process is available to address it.
Reference equipment is uniquely identified, held under controlled conditions, and recalibrated on a defined interval that is shortened when drift data justifies it. Equipment that is damaged, overloaded, or shown to give suspect results is removed from service and labeled until it has been checked and returned to use in writing.
Management System
The work sits inside a documented management system:
Controlled documents
Procedures carry issue and revision status.
Retained records
Retained for a defined period and retrievable against a certificate number.
Audit and review
Internal audit and management review run on a schedule.
Corrective action
Nonconforming work and improvement actions are tracked to closure, and their effectiveness is checked afterwards.
Impartiality and Complaints
Risks to impartiality are identified and controlled, and results are reported on their merits regardless of the commercial outcome. Complaints and appeals are a formal input to that system — the process, including the response commitment, is set out on the complaints policy page. How results should and should not be read is covered on the disclaimer page.
