Standards calibration — Fluid volume

Volumetric standards and hydrometers used by Measurement Canada inspectors and authorized service providers are calibrated for use in the field.


Method:

Gravimetric calibration of "to deliver" liquid volume of:

  • Open neck provers and test measures: 1 to 40 L; sight glass or slicker plate design
  • Graduated glass cylinders 10 to 2000 mL
  • Level 1 open neck provers: 40 to 500 L with sight glass design and bottom drain assembly

Gravimetric calibration of "to contain" liquid volume of:

  • Steel stoppered pycnometers: 100 to 1000 mL

Volumetric calibration of "to deliver" liquid volume of:

  • Level 2 and 3 open neck provers: 20 to 2500 L

Hydrostatic weighing of:

  • Pressure hydrometers (0.470 to 0.510 ×0.0005 g/cm³ or 0.500 to 0.550 × 0.0005 g/cm³, stem diameter up to 17 mm, length up to 370 mm) is performed by the National Research Council (NRC) and corrections for liquefied propane gas are performed by Measurement Canada

Calibration location:

  • Level 2 and level 3 volume standards are calibrated by Measurement Canada regional offices.
  • All other devices are calibrated by Measurement Canada's Approval and Calibration Services Laboratory (ACSL) in Ottawa.
    • Pressure hydrometers measurements are performed the NRC and corrections performed by Measurement Canada's ACSL. These devices must first be submitted to the ACSL.

Fees:

  • N/A for devices used under the application of the Weights and Measures Act.
  • 60$/h for devices used under the application of the Electricity and Gas Inspection Act.

Only standards used by Measurement Canada inspectors and authorized service providers are calibrated by Measurement Canada's laboratories. Standards and apparatus must be authorized and registered with Measurement Canada to qualify for this service.

ISO/IEC 17025 accreditation

Many of the calibration services offered by Measurement Canada's Approval and Calibration Services Laboratory (ACSL) are accredited to international standard ISO/IEC 17025—General Requirements for the Competence of Testing and Calibration Laboratories. This accreditation is granted by the Standards Council of Canada, Canada's accreditation body for calibration and testing laboratories via the Calibration Laboratory Assessment Service (CLAS) program of the National Research Council of Canada. Measurement Canada's ACSL is accredited to perform calibrations listed on its CLAS certificate, number 2009-03. All accredited calibrations are traceable to the International System of Units or to standards acceptable to the CLAS program. The certificate of calibration and designation created by Measurement Canada for each calibration of a standard that falls under this scope bears the CLAS logo.

The ISO/IEC 17025 standard requires that certain information be reported on the certificates issued for calibrations by accredited laboratories or be made available to clients if they request it. In its role as a regulator, Measurement Canada chooses what information is relevant to report on the certificates that it issues for calibrations. The ACSL keeps any information not presented on the certificate, but required under ISO/IEC 17025, and makes it available to its clients upon request. In accordance with Government of Canada privacy policies, this information is only provided to the requestor of the calibration service for the certificate in question. To request this information, add a comment on the Calibration Services Request form or contact the ACSL.

Request calibration services

To request calibration services, complete the Calibration Services Request form for each standard. If you encounter any difficulties filling out the form, please contact the ACSL.

You may wish to notify the volume laboratory of when it can expect to receive your standard(s) in order to help expedite the calibration process.

Shipping requirements

Applicants are responsible for shipping arrangements and charges.

Level 2 and 3 open neck provers (20 to 2500 L) are to be sent to a regional Measurement Canada office.

All other volumetric standards, including pressure hydrometers, are to be sent to:

Measurement Canada, ACSL
Standards Building
151 Tunney's Pasture Driveway
Ottawa, Ontario
K1Y 1G9

A completed copy of the Calibration services request (CSR) form must accompany each device shipped. Ensure that an active/valid shipping account number for return shipping is identified on the form.

Packaging

Packages not meeting these requirements listed below may not be accepted.

  • Standards must be in a reusable container.
  • Containers must not be sealed with nails. Crates or boxes with a hinged door or cover fastened with screws are acceptable.
  • Provisions for re-packaging and the return of standards must be made before delivery. See Return of standards for more details.

International shipments and importing requirements

It is your responsibility to ensure that:

  • Your shipment complies with all customs and importation requirements.
  • You have pre-paid all applicable customs and importation fees and charges.
  • All brokerage, import, transportation, insurance and any other incidental fees and forms must be prepaid and accompany the shipment.

Consult the Canada Border Services Agency to ensure you are aware of all customs and importation requirements and fees and charges that apply to your shipment.

Return of standards

Return of standards — International

Measurement Canada will provide you with the weight and dimensions of the package. It is advisable to wait for this information prior to making further arrangements for the return shipping of your standards.

All paperwork (waybill, commercial invoice and any other related forms) must be submitted and faxed to the attention of Shipping and Receiving at 613-952-8170.

Any cost associated with the re-packaging of a device is the customer's responsibility.

Return of standards — National

Arrangements for the return of your standards are your responsibility. However, Shipping and Receiving can also make the arrangements provided that an account number and waybill are provided in advance.

Any cost associated with the re-packaging of a device is the customer's responsibility.
