The ISO/IEC 17025 Management System has been adopted in the United States as the standard for testing and calibration laboratories for quality and competence. In addition, this standard has been recognized worldwide since 1990. ISO/IEC 17025 expands upon the requirements of ISO 900X.

Yes, not only must an ISO/IEC 17025 accredited lab pass the initial in-depth audit and assessment by the accreditation body, it is also fully re-audited every two years to determine that the lab continues to meet the requirements of accreditation. Additionally, ISO/IEC 17025 accredited labs must partake in proficiency tests every year. This assures you of continuity of competency and performance. Non-accredited labs are free to maintain or modify their procedures, processes, and competency level as they decide.

A Certificate of Accreditation and Scope outlining the labs accredited calibration disciplines and best measurement capabilities is awarded after the successful completion of an in depth audit. The labs Certificate and Scope should be available for review.

All of our calibration equipment is traceable to NIST. We do not supply NIST numbers in accordance with NCSLI Position Statement 96-1: "test report numbers should not be used nor required as proof of the adequacy or traceability of a test or measurement". NIST, NVLAP and A2LA have concurred with this position. NCSLI also notes that international standards ISO 900X, ISO Guide 25 (ISO/IEC 17025), ISO 10012 and ANSI/NCSL Z540-1 do not require the use or reporting of NIST test report numbers.

It is a calculated numerical value outlined (where requested) on our Calibration Certificates, associated with the results of the measurement(s). The measurement uncertainty value defines the range of the values that could reasonably be attributed to the measured quantity. We calculate measurement uncertainty in accordance with the ISO GUM (Guide to the Expression of Uncertainty in Measurement) expressed at a 95% level of confidence with a coverage factor of K=2.

When our Calibration Certificate notates that the instrument calibrated either passed or failed its specified tolerance, the measurement uncertainty was not taken into account. This method has been the predominant requested practice from our client base and therefore was chosen as our default practice. If you would prefer to have measurement uncertainty taken into account when we assess pass/fail compliance on your calibration certificate, please notify us and we will be happy to comply.

If measurement uncertainty is accounted for in determining pass/fail compliance, and the calibration result of an instrument is above or below the tolerance limits by less than the measurement uncertainty, it is not possible to state that the instrument either passed or failed its tolerance limits, and therefore will be noted on the Calibration Certificate as such. For additional guidance, see ILAC G8:1996 Guidelines on Assessment & Reporting Compliance with Specifications.

Please be advised that the quality system standard for calibration, ISO/IEC 17025, which we are accredited to, states “a calibration certificate or calibration label shall not contain any recommendation on the calibration interval except where it has been agreed upon with the client. This requirement may be superseded by legal regulations”.

This clause was added to ensure that quality personnel setting the intervals for their own instrumentation are determining their calibration intervals based upon their own quality system requirements and tolerances, which may not concur with the independent calibration laboratory which performs the calibration.

We will provide the calibration due dates on your certificates and labels based on the calibration intervals you provide us.

For guidance on what an appropriate calibration interval should be, see NCSLI – Recommended Practice 1 (RP-1 Establishment and Adjustment of Calibration Intervals). This publication can be purchased directly from www.ncsli.org.

Typical turnaround time ranges from 1 to 2 weeks, but expedited service is available.

We offer 24 and 48 hour expedited service for most instrument calibration service, however scheduling in advance with our Customer Service Department is required. Instrument repairs cannot consistently be turned around within 24 to 48 hours, as repair parts may need to be procured.

We will contact you with a price quote for approval prior to performing repair service.

No, but we do require a purchase order number or the credit card information prior to us servicing your instrument(s). The purchase order or credit card information can be outlined on the Calibration Work Order, or provided to us via fax or email, or simply included with the instrument shipment.

Yes, we do require a purchase order number or the credit card information prior to us servicing your instruments. The purchase order or credit card information can be outlined on the Calibration Work Order, or provided to us via fax or email, or simply included with the instrument shipment.

When using Purchase Orders, our payment terms are net 30 days. We also accept American Express, Visa and Master Card.

We have a minimum on-site service charge of $250.00

For the most common instruments sent in to us for calibration, prices are outlined on the Calibration Work Orders. Additionally, our Customer Service Department can be reached at 781-982-7125.

If you loose a Calibration Certificate, contact our Customer Service Department at 781-982-7125 and we will provide you a replacement free of charge. Alternatively, Calibration Certificates and Instrument Cal-Due Reports are available via the internet using DATAVIEW free of charge.

All customers are faxed and/or emailed with a Cal-Due Report at least 2 weeks prior to the calibration due date. Our customers can also access their Cal-Due Reports and Calibration Certificates free of charge via the internet using DATAVIEW.
