Paragraph 7 Test purchases
An enforcement authority shall have power, for the purpose of ascertaining whether any provision of these Regulations has been contravened, to purchase, or to authorise an officer of the authority to purchase, any regulated appliance.
Where—
a regulated appliance purchased under this paragraph on behalf of an enforcement authority is submitted to a test;
the test leads to the bringing of proceedings in respect of an offence under these Regulations; and
the authority is requested to do so and it is practicable for the authority to comply with the request,
the authority shall allow the person from whom the regulated appliance was purchased or any person who is a party to the proceedings or has an interest in the regulated appliance to have that appliance tested.
A test of a regulated appliance purchased under this paragraph, or seized or detained under paragraph 8 (power to enter premises and inspect, seize and detain a regulated appliance etc), shall be carried out in accordance with the test procedures of the harmonised standard.
