1.0 Purpose

The purpose of this bulletin is to specify Measurement Canada's policy for the issuance of certificates, and the recording of test results and reverification periods when performing initial verifications and reverifications of electricity and gas meters under the Electricity and Gas Inspection Act.

2.0 Scope

The policy requirements specified in this bulletin apply to Measurement Canada inspectors and accredited organizations.

3.0 Definitions

The key terms used in this bulletin are defined as follows:

Certificate

An official document issued pursuant to section 14 of the Act which certifies that the meters have been inspected and indicates the verification results.

Verification

All the operations carried out by an inspector or accredited meter verifier having the object of ascertaining and confirming that a meter entirely satisfies specified requirements. Any reference to "verification" includes both the initial verification and reverification of meters, whether by 100% inspection or through the use of statistical sampling methods authorized by Measurement Canada. It also includes the application of a verification mark.

4.0 Background

In accordance with paragraph 21(h) of the Electricity and Gas Inspection Regulations (Regulations), the certificate issued following the verification of an electricity or gas meter must contain the results of the tests on that meter at all points tested.

The policies contained in this bulletin respond to several questions received by Measurement Canada on certain fundamental areas in the preparation of inspection certificates. Additional clarifications have also been included as a result of questions pertaining to the implementation of new requirements pertaining to the lengthening of initial verification periods for electricity and gas meters. Following the review of inspection information requirements and the need for possible amendments to section 21 of the Regulations, this bulletin may be revised to include further directives on the preparation of inspection certificates.

5.0 Administrative requirements for the issuance of certificate

5.1 Inspector

Pursuant to section 14 of the Act, the inspector shall issue a certificate upon the verification or reverification of a meter(s).

5.2 Accredited organizations that own the meter

Where an accredited organization verifies or reverifies a meter which they own, the accredited organization is not required to issue a certificate as prescribed by section 14 of the Act. In such cases, the accredited organization may instead choose to maintain all of the information prescribed by section 21 of the Regulations in records that are required to be kept pursuant to sections 11 and 28 of the Regulations.

5.3 Accredited organizations that do not own the meter (meter service organization)

Pursuant to section 14 of the Act, an accredited organization shall issue a certificate upon the verification or reverification of a meter(s). In addition, the accredited organization shall maintain records pursuant to section 28 of the Regulations. In the case of meters that do not achieve a verified status, the accredited organization shall record the information prescribed by section 21 of the Regulations on either the certificate, or on records which are authorized and controlled under the organization's quality assurance program.

5.4 Information location

5.4.1 The information required on the certificate issued pursuant to section 14 of the Act, may be recorded on an accompanying work document(s) contiguous to the certificate, under the condition that the work document(s) contains the following:

  1. identification number of the certificate;
  2. original handwritten signature of the inspector or the accredited meter verifier;
  3. date of the verification or reverification; and,
  4. page number.

5.4.2 The total number of work documents shall be recorded on the host certificate.

6.0 Recording test results

6.1 Accuracy tests

The results of each specified accuracy test which is subject to a maximum permissible error shall be recorded on the inspection certificate.

Note: In addition, in situations where test results incorporate a bias which has been authorized by Measurement Canada, the bias value applied to the test result shall be recorded.

6.2 Functionality tests

The results of each specified functionality test not subject to a maximum permissible error (e.g. coil association test or no load test in an electricity meter) may be indicated with a mark or symbol to indicate pass or failure. Where all devices on a certificate have the same test result for a given functionality test, one record per certificate is acceptable for all meters named on the same certificate.

6.3 Recording of initial reverification periods

6.3.1 Where a particular make/model or class of electricity or gas meter is granted a conditionally lengthened initial reverification period, the initial reverification period recorded on the inspection certificate shall be the one corresponding to the meter's base initial reverification period prescribed in electricity bulletin E-26 (section 5.2) or gas bulletin G-18 (section 5.2). A meter owner's records shall also indicate the base initial reverification period for the duration that the conditionally lengthened status applies.

6.3.2 Where a conditionally lengthened initial reverification period is recognized as unconditional (i.e. compliance with S-S-05 has been demonstrated), meter owners shall update their meter records for the subject make, model, or class of electricity or gas meter, to reflect the lengthened initial reverification period.

6.3.3 Inspection certificates are not required to be re-issued if the initial reverification period changes.

7.0 Revision

The purpose of this revision is to clarify:

  1. the initial reverification period that is to be recorded on the certificate, or kept in the records for electricity and gas meters with regards to lengthened initial reverification periods; and
  2. that an original hand-written signature be used on the inspection certificates.
