41、for which they are designed can slide freely through them. It shall not be possible for gutters to be lifted out of a bracket by strong wind. This shall be achieved either through the design of integral lugs or nibs on the bracket itself or by providing separate clips or springs to attach the gutter

42、 to the bracket. Clips and springs are not required to be of the same material as the bracket to which they are attached, but shall have a corrosion resistance of Class A, as given in Table 2, if attached to a gutter bracket of corrosion resistance Class A. Clips and springs shall be manufactured fr

43、om one of the following materials: any of the materials specified in Clause 4; polyamide plastic; galvanized and prepainted steel sheet having an average coating mass of not less than 275 g/m2.Where both the clip or spring and the gutter bracket are manufactured from metal, care shall be taken to av

44、oid contact between incompatible metals, thereby reducing the risk of electrolytic corrosion. 6.2 Load bearing capacity Gutter brackets shall be divided into three classes according to their load bearing capacity. When tested in accordance with Annex B, brackets of 80 mm or greater top opening width

45、 (i.e. brackets of Classes H and L) shall support the loads given in Table 3 without collapse and without causing permanent deflection exceeding 5 mm at the outer end of the bracket.

46、H Brackets for light duty 500 L Brackets for gutters below 80 mm top opening width O6.3 Holes for fastenings Rafter brackets shall have not less than two holes for fastenings. Where these brackets are designed to be fixed either by nails or screws, the holes shall not be less than 12 x (hole diamete

47、r) apart. Where the bracket is designed to be fixed only by screws, the holes shall not be less than seven diameters apart and the bracket shall be marked “S”. Fascia brackets of the heavy-duty load-bearing Class H shall have not less than two holes for fastenings. When these holes are one above the

48、 other on the vertical centre line of the bracket, they shall be not less than four diameters apart. When the holes are on each side of the centre line and in the same horizontal plane, they shall be not less than seven diameters apart. When the holes are on each side of the centre line but at diffe

49、rent levels, they shall be not less than five diameters apart. Fascia brackets of the light duty load-bearing Class L shall either have a single hole on the vertical centre line of the bracket or have the same arrangement and spacing of holes for fastenings as for fascia brackets of load-bearing Class H. All holes shall have a minimum diameter of 5 mm, after application of any corrosion resistance coating. Minimum diameter spacings between holes shall be measu
