Regulation 5 Testing of meters
Where a meter has been submitted to the Director under regulation 4, a meter examiner shall carry out, or procure the carrying out of, such tests as he considers are necessary to determine whether the pattern or construction of the meter is such that any meter of that pattern or construction will be capable of accurately recording the quantity of electricity for which the meter is intended to operate.
In carrying out his functions under paragraph (1), a meter examiner shall have due regard to any national or international technical standards relating to meters of that or a similar pattern or construction.
In relation to any one or more of the tests which the meter examiner considers necessary, he may require the person applying for approval to procure the carrying out of specified tests at any premises approved by the Director for carrying out tests of the type specified.
A test referred to in paragraph (3) shall, if the meter examiner so requires—
not be carried out until the meters have been sealed by him for identification purposes; and
be carried out in his presence,
and the meters shall on completion of the test be delivered to the meter examiner.
A meter which has been submitted to the Director under regulation 4 shall not be repaired or modified by any person, other than by a meter examiner for the purpose of carrying out tests in accordance with this regulation, until a notification has been issued under regulation 6 or 7.
