BS 8539:2012 pdf download – Code of practice for the selection and installation of post-installed anchors in concrete and masonry Suppliers of anchors should take care to supply anchors as ordered by customers. Specifications of anchors that have been ordered should not be changed unless the change management procedure in Clause 10 has been followed and the proposed change has been approved by the specifier. 4.2 Designer The designer should take into account the preliminary design considerations listed in 5.2. The designer should also supply all necessary information to the specifier as required to complete the selection process as outlined in 6.3. 4.3 Specifier The specifier should determine the most appropriate anchor for the particular application, by following the selection process given in Clause 5 and using the appropriate design method for that anchor. NOTE 1 Guidance on design methods is given in Annex A. The specifier should seek technical assistance from the manufacturer/supplier where necessary and, if the specifier is not the designer, should seek information from the designer as recommended in 6.3. The selection process should take into account the most onerous loads to which the anchor might be subjected, and the direction of the loads, including temporary loading applied during the erection phase. Once the selection and design processes are completed, the specifier should specify the anchor explicitly and completely, so that the anchor installed on site fulfils the design criteria (see 5.5 and 6.4). If any party proposes an alternative anchor to that specified, the specifier should ensure that the change management procedure outlined in Clause 10 is carried out. If for any reason the specifier determines that site tests of anchors are needed, then the need for such tests should be communicated to all relevant parties, e.g. the contractor and tester, so that they know the objective of such tests and when they are to be carried out, and that they have all the necessary data to carry out such tests (see 6.6). The specifier should then ensure that any actions consequent on the results of such tests are put in hand. NOTE 2 In the case of tests to determine the allowable resistance, this might mean that the proposed anchor is confirmed as the specified anchor, or that it is not suitable and an alternative anchor is to be proposed and, possibly, tested. In the case of proof tests, it might mean confirmation to...
