This British Standard gives recommendations for the system design, installation, use, maintenance and inspection of anchor systems incorporating anchor devices conforming to BS EN 795, PD CEN/TS 16415 and/or anchor systems conforming to BS 8610.

This British Standard also gives recommendations for the inspection of anchor systems installed prior to this edition of the British Standard.

NOTE 1 Anchor systems installed prior to this edition of the British Standard, but which have been inspected in accordance with Section 4, can only be certified as meeting the inspection recommendations of Section 4. The inspector can only claim that the anchor system conforms to the British Standard to which it was originally installed, e.g. ā€œthe anchor system was installed in accordance with BS 7883:2005 and the inspection has been carried out in accordance with BS 7883:2019, Section 4ā€.

This British Standard is only applicable to anchor systems for the direct attachment of PFPE for use in the workplace.

This British Standard is not applicable to:

  1. the lifting of equipment;

  2. anchor points comprising holes formed in the base material for the direct attachment of personal fall protection equipment (PFPE), e.g. hole drilled through steel girder;

  3. anchor points formed by the welded attachment of bars or plates to steel structures for the direct attachment of the PFPE, e.g. loops of steel bar or flat plates incorporating a hole, welded to a steel structure, unless:

    1. such anchor points form part of a manufactured product which has been successfully tested in accordance with BS 8610; or

    2. the manufacturer, installer or inspector of such anchor points can demonstrate that the anchor point conforms to all relevant requirements of BS 8610, BS EN 795 or PD CEN/TS 16415, in which case the documentation certifying conformity to BS 8610, BS EN 795 or PD CEN/TS 16415 becomes part of the documentation provided to the duty holder;

  4. anchor systems for attachment of collective protection systems, e.g. work positioning platforms and fall arrest nets; and

  5. personal fall protection systems (PFPS) and equipment for use in leisure activities or in professional and private sports activities.

This British Standard is intended for use by system designers, installers, inspectors and users of anchor systems, including other interested parties, e.g. architects and structural engineers, and those who are responsible for the design of safe access and egress on buildings and structures.

NOTE 2 Advice on the selection, use and maintenance of PFPS and equipment for use in the workplace is given in BS 8437 and recommendations and guidance on the use of rope access methods for industrial purposes are given in BS 7985.
