Interpretation

A2—(1) In these regulations—

(2) For the purposes of these regulations any of the following operations shall be deemed to be the erection of a building—

(a)the re-erection of any building or part of a building when an outer wall of that building or (as the case may be) that part of a building has been pulled down or burnt down to within 3 metres of the surface of the ground adjoining the lowest storey of the building or of that part of the building;

(b)the re-erection of any frame building or part of a frame building when that building or part of a building has been so far pulled down or burnt down as to leave only the framework of the lowest storey of the building or of that part of the building; and

(c)the roofing over of any open space between walls or buildings.

(3) For the purpose of these regulations, the installation of a cesspool, septic tank or similar structure shall be treated as the provision of a service and not as the erection of a building.

(4) In these regulations any reference to a building shall extend to and include any part of a building, and any reference to the purpose for which a building is used shall extend to, include or mean the purpose for which it is intended to be used.

(5) Where in relation to a specific purpose, a European Council Directive prescribes a requirement in relation to a particular characteristic of a material, component or other manufactured product, or part thereof, then where that characteristic complies with that requirement, it shall be deemed to satisfy any requirement of these regulations insofar as it relates to that purpose.

(6) In these regulations any reference to a British Standard or British Standard Code of Practice shall be construed as a reference to an appropriate British Standard or British Standard Code of Practice issued by the British Standards Institution and also to—

(a)a relevant harmonised standard or a relevant standard or code of practice of a national standards body, or equivalent body, of any European Economic State;

(b)any relevant international standard recognised for use in any EEA State;

(c)any appropriate, traditional procedures of manufacture of an EEA State where these are the subject of a written technical description sufficiently detailed to permit assessment of the goods or materials for the use specified; or

(d)a European Technical Approval issued in accordance with the Construction Products Directive (or, until procedures are available for the issue of such approvals, a specification sufficiently detailed to permit assessment):

(7) For the purposes of these regulations, any construction product (within the meaning of the Construction Products Directive) which bears a CE marking shall be treated as if it satisfied the requirements of any appropriate British Board of Agrément Certificate, British Standard or British Standard Code of Practice relating to such a product, where the CE marking relates to the same characteristic and specific purpose as the Certificate, Standard or Code of Practice.

(8) Where for the purposes of these regulations testing is carried out, it shall be carried out by an appropriate organisation offering suitable and satisfactory evidence of technical and professional competence and independence and such condition shall be satisfied where the testing organisation is accredited in an EEA State in accordance with the relevant parts of the EN 45000 series of standards for the tests carried out.

(9) Any note in a Table or Schedule shall be treated for all purposes as a substantive provision.

(10) Any reference in these Regulations to a Table identified only by a letter shall be construed as a reference to the Table so identified in Schedule 5.

(11) Any reference in these regulations, other than in paragraphs (6)(a) to (d), to a publication shall be construed as follows—

(a)in any case where no date is included in the reference, the reference is to the edition thereof current at 22nd November 2000 together with any amendments, supplements or addenda thereto published at that date;

(b)in any case where a date is included in the reference, the reference is to the edition of that date, together with such amendments to the publication, as are mentioned in Schedules 4, 5 and 6; and

(c)any reference to any publication is a reference to so much only thereof as is relevant in the context in which such publication is quoted.

A3  Where any provision (in these regulations called a deemed-to-satisfy provision) states that the use of a particular material, method of construction or specification shall be deemed to satisfy the requirement of any regulation or part thereof, that provision shall not be construed so as to require any person necessarily to use such material, method of construction or specification.
