BS 8610:2017 download.Personal fall protection equipment Anchor systems-Specification.
BS 8610 is intended for the type testing of anchor systems and gives only minimum performance requirements. It is essential that anchor systems are designed and manufactured so that, in the foreseeable conditions of use for which they are intended, the user is able to perform the risk-related activity while being appropriately protected at the highest possible level.
BS 8610 presumes that the manufacturer of the relevant parts of the anchor system, for the sake of consistency and traceability, operates a quality management system which complies with regulations in force at the time. Guidance on the form this quality management system could take can be found in BS EN ISO 9001.
0.2 Advice on using this British Standard
It is recommended that BS 8610 is read in the following order to ensure the correct category of anchor system is selected and tested.
a) Clause 0. Table 1 and Table 2: depending on which category of anchor system has been chosen, select:
1) the category of anchor system, i.e. non-load-limiting or load-limiting;
2) the type of anchor system, i.e. type A, type C or type D; and
3) an application or applications that apply (application codes 1 to 7).
3.8 energy-dissipating element
element of an anchor system that dissipates the kinetic energy developed during a fall from a height NOTE Wire rope used in type C anchor systems is not considered to be an energy-dissipating element.
3.9 evacuation

3.10 evacuation system
personal fall protection system by which a person or persons can transfer themselves, or be transferred, from a place of danger to a place of safety, in such a way that a free fall is prevented
3.11 extremity anchor

4.1 General requirements
4.1,1 Anchor systems shall be tested In the base materials that the manufacturer permits, unless otherwise specified In the relevant test methods (see C1iue S). When tests are earned out in such base materials. they shall be carried out In base materials of suitable strength and dimensions so as to validate the structural limitations to be provided In 2.3 d).
4.1.2 Anchor systems shall be tested in each relevant salety-critical direction. e.g in tension, in shear, or a combination of the two (see 5.4.3 and Figure 10).
by the manufacturer and test laborator) shall be tested. ensuring the limit Is set for the configuration that could be offered. e.g. the tallest post, each type of base plate.
4.2.4 lIthe geonwtr) configuration or material of an anchor device, including the structural anchor, diflers from the one that has been tested as part of the anchor system, the anchor system shall be verified by testing In accordance with Clause 5, or proven by cakubtion with the results recorded.
4.1.5 DurIng deformation tests, cracks, ruptures or unintended tears of any part of the anchor system. visible with normal or corrected vision, shall not be permitted.
4.1.6 Where deformation tests and static strength tests are carried out simultaneously, (i.e. for type Al and type Dl anchor systems), cracks, ruptures or unintended tears of any part of the anchor system, visible with normal or corrected vision, shall not be permitted.
4.1.7 During dynamic performance tests and static strength tests, any sign or evidence of partial (allure of the anchor system. e.g. cracks, ruptures or unintended tears, visible with normal or corrected vision, shall not be classed as a failure, but shall be detailed in the test report (see Annex A).
4.2 Pee-testIng verification and recordIng requirements
4.2.1 Prior to testing, elements of the anchor system, when appropriate, shall be verified by
a) confirming appropriate documentation;
bJ visual and/or tactile examination;
c) weighing elements: and
d) measuring.
in order to ensure conformity to 413 to 4,Z.B, 4,3 and £4. with the exception of 4,3,L1 which shall be checked upon completion of the corrosion resistance test (see 5,$).

4.2.3 If an element of the anchor system can be removed, it shall be designed such that It can only be detached after carrying out two separate, consecutive and deliberate manual actions.
4.2.4 For anchor systems Which Include removable elements, those elements shall be such that they cannot appear to be positively locked together when they are not, due to incorrect assembly.
4.2.5 Anchor points shall be so designed to ensure easy engagement and disengagement of the connector or connectors supplied or recommended by the manufacturer. Gales or other dosing mechanisms of the connector shall he able to close and be locked without interference when engaged In the anchor point. Connectors shall be able to rotate freely around the anchor point in such a way that they can selI’align Ithe directions of use and In the principal safety-critical directions when under load, Rotation and alignment under load shall not be so Impeded to allow loading on the gale or other closing mechanism.
