BS 8298-1-2010 pdf free download.Code of practice for the design and installation of natural stone cladding and lining — Part 1: General.
Test regime 1: Limited testing to verify that the current production is consistent with past results, e.g. density and porosity, water absorption, flexural strength of specimens at “project” thickness.
Test regime 2: Limited testing as in test regime 1 but with additional testing of particular areas of concern, e.g. strength test for a novel fixing system or freeze/thaw tests, and other relevant durability tests if in a susceptible location.
Test regime 3: Extensive additional testing and FPC testing, including a complete initial type test in accordance with BS EN 1469 and regular FPC tests (such as density and porosity, water absorption, flexural strength with additional tests relevant to the particular use/location, e.g. strength test for a novel fixing system or freeze/thaw tests, and other relevant durability tests if in a susceptible location).
5.2 Fixings
NOTE This subclause refers to alloys readily available in the UK. This does
not preclude the use of other alloys if their suitability can be demonstrated.
5.2.1 Stainless steel fixings
NOTE Stainless steel is the name give to a group of corrosion-resistant alloys that contain varying percentages of chromium and nickel. The group includes austenitiç martensitic ferritic duplex and super duplex alloys. It is only the austenitic range of alloys that are currently used for the manufacture of fixings for cladding.
All stainless steel fixings selected for use, i.e. cramps, ties, angles and other fabrications, should be of austenitic stainless steel sheet, strip and plate conforming to 85 EN 10088-2, and stainless steel rod and bar conforming to BS EN 10088-3.
The grade of stainless steel should be selected in accordance with its application, as given in Table 4 taking into account the working stresses required, the location of the building and level of exposure.
It is essential that welding is undertaken only where the necessary facilities, expert knowledge, inspection and testing facilities and skills are available. Scaling and discoloration caused by welding, hot working and heat treatment operations should be removed by suitable cleaning methods in order to maintain the intrinsic corrosion resistance of the material. Advice should be obtained from the steel supplier/manufacturer.BS 8298-1-2010 pdf free download.
