Calibration Certificate Comparison     |     Calibration Lab Certificates

Depending on the quality policy requirements of your company and the required industry standards, Transcat offers a choice of non-accredited and 17025 accredited calibration service levels. Click here for a detailed description of Transcat's new calibration service levels.

• Calibration Without Data (Non-accredited)
• Calibration With Data  (Non-accredited) 
• Accredited Calibration With Data & Uncertainties (Simple Acceptance) 
  • With Optional Guard Banding 
  • With Optional Probability of Compliance to the Specifications (PCS) 
  • With Optional Guard Banding and PCS 

No matter which calibration service option you choose, when you calibrate with Transcat, you can expect prompt and responsive service including five to seven business day turnaround on most instruments.

Note: Per ILAC P14, Calibrations that do not include reported measurement uncertainties prevent the respective instrument from propagating traceability.  Visit our resource page for more information on ILAC P14, Z540.3 and other quality requirements.

Calibration without Data (Non-accredited)

This level of service provides you with a calibration certificate and sticker for your instrument.  We will evaluate it to a Pass/Fail criterion and no as-found or as-left data will be recorded or provided.  This level is unaccredited and not traceable to a national standard.  This level of calibration will not have an accreditation logo.

Calibration with Data (Non-accredited)

This level of service provides you with a calibration in which the as found and as left data will be recorded and provided along with your calibration certificate and sticker for your instrument.  We will also provide you a separate out of tolerance (OOT) report, as well as Test Uncertainty Ratios (TUR) when the TUR’s are < 4:1.  This level is unaccredited and not traceable to a national standard.  This level of calibration will not have an accreditation logo.

Accredited Calibration With Data & Uncertainties (Simple Acceptance)

This level of service provides you with a calibration in which the as found and as left data with measurement uncertainties and test uncertainty ratios (TUR) will be recorded and provided along with your calibration certificate and sticker for your instrument.  This level fully complies with ISO 17025, and meets NIST Traceability requirements. Transcat’s default Guard Banding method will be Simple Acceptance (ASME B89.7.3.1) to be applied as your Decision Rule unless you select one of the Guard Band methods below. This level of calibration will have an accreditation logo.

With Optional Guard Banding

This level of service provides you with a calibration in which the as-found and as left data with measurement uncertainties, test uncertainty ratios (TUR) and Guard Banding will be recorded and provided along with your calibration certificate and sticker for your instrument.  This level fully complies with ISO 17025 and Z540.3 standards and meets NIST Traceability requirements. This level of calibration will have an accreditation logo.

Customers may also choose an alternate Guard Banding Decision Rule. This must be specified at the time of placing their order

• ANSI/NCSL Z540.3: 2006, Method 5
• ANSI/NCSL Z540.3: 2006 Method 6
• ILAC G8:2019, Table 1
• ASME B89.7.3.1, clause 5.2, Stringent Acceptance
• ASME B89.7.3.1, clause 5.3, Relaxed Acceptance

With Optional Probability of Compliance to the Specifications (PCS)

This level of service provides you with a calibration in which the as-found and as left data with full test uncertainty ratios (TUR) and Transcat’s PCS measurement risk feature will be recorded and provided along with your calibration certificate and sticker for your instrument.  This level fully complies with ISO 17025 and Z540.3 standards, and meets NIST Traceability requirements.  Transcat’s PCS feature quantifies the measurement risk with a threshold level of 98% PCS (equivalent to 2% PFA); you may set this threshold to a different level, depending on your quality requirements and risk management policy.  For more information on Transcat’s PCS tool, check out our white paper. This level of calibration will have an accreditation logo.

With Optional Guard Banding and PCS

This level of service provides you with a calibration in which the as-found and as left data with measurement uncertainties, test uncertainty ratios (TUR) and Guard Banding and Transcat’s PCS feature will be recorded and provided along with your calibration certificate and sticker for your instrument.  This level fully complies with ISO 17025 and Z540.3 standards, and meets NIST Traceability requirements.  With this service level, the Guard Band method selected will be used to identify Pass/Fail for the Guard Band Acceptance Limits while Transcat’s PCS feature will simply quantify the exact measurement risk that exists for each measurement result.  This level of calibration will have an accreditation logo.

Customers may also choose an alternate Guard Banding Decision Rule. This must be specified at the time of placing their order
