19、12:2005 (E) 3 Foreword This document (EN 612:2005) has been prepared by Technical Committee CEN/TC 128 “Roof covering products for discontinuous laying and products for wall cladding”, the secretariat of which is held by IBN. This European Standard shall be given the status of a national standard, e

20、ither by publication of an identical text or by endorsement, at the latest by August 2005, and conflicting national standards shall be withdrawn at the latest by August 2005. This document supersedes EN 612:1995. According to the CEN/CENELEC Internal Regulations, the national standards organizations

21、 of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia,

EN 612:2005 (E) 4 Introduction This document specifies product requirements, derived from performance requirements established for various applications and is supported by separate standards for specific and common test methods in the framework of respe

23、ctive material standards. The performance of a gutter and drainage system made with these products depends not only on the properties of the products as they are defined by this document. The design, construction and behaviour of the relevant parts of the building also have an effect on the performa

24、nce of the system. EN 612:2005 (E) 5 1 Scope This document specifies requirements for eaves gutters and rainwater down-pipes made from metal sheet. It establishes the general characteristics, designation system, classification, marking and quality requirements for the products. The document applies

25、to eaves gutters and external rainwater down-pipes that are supported by metal brackets and used to drain away rainwater. The shape and dimensions of a gutter are defined by the quantity of water to be drained away from the roof to the down-pipes and by architectural design requirements. The documen

26、t specifies the requirements for gutters and rainwater down-pipes which enable these products to meet all usual service conditions such as catching and draining away rainwater, melted snow or ice water from a building to a drainage system or a sewer outside the building. Requirements for fixings, su

27、pporting construction, flashings or the method of making joints between the different components are not included in this document. This document does not specify requirements for eaves gutters handmade on site. 2 Normative references The following referenced documents are indispensable for the appl

35、t metal sheet (see Figure 3) 4 Shapes 4.1 Gutters 4.1.1 Components A gutter, formed from one piece of metal sheet, shall consist of the following four main parts: bead; front; bottom and back. EN 612:2005 (E) 7 Together, these parts form a trough-shape with an opening at the top to admit rainwater.

36、The most commonly used shapes are shown in Figure 1. The shape of the gutter is described by bead dimensions; height of the front; outside width of the bottom; height of the back; upper opening width and developed width. 4.1.2 General requirements on the main parts 4.1.2.1 Bead The bead has to fulfi

37、l two functions, a) to give stiffness to the gutter in both the horizontal and the vertical direction, b) to form a fixing point for the gutter brackets. The shape of the bead shall meet an agreed drawing within the tolerances given in 7.1.2. Three of the most widely used shapes of bead are shown in

38、 Figure 2. The diameter of the bead, dimension d in Figure 2, shall be not smaller than the corresponding value in Table 1. The load bearing capacity and stiffness of other beads shall be not less than that of a bead of a circular type, Figure 2, shape I, of the same material in both the horizontal

39、and the vertical direction. This shall be proved by calculation of the modulus of section. 4.1.2.2 Front The shape and dimensions of the front shall meet an agreed drawing within the tolerances given in 7.1.2. The vertical height of the front, dimension a in Figure 1, or the sum of bead diameter plu

40、s vertical height if the front, dimensions a + d in Figure 1 or Figure 2b, shall be not less than the corresponding value given in Table 1. 4.1.2.3 Bottom The shape and dimensions of the bottom are dependent upon the type of gutter. The shape and dimensions of the bottom, together with those of the

41、front and the back, control the upper opening width, dimension e of Figure 1. If the outside width of the bottom, dimension b of Figure 1, is defined, the tolerances given in 7.1.2 apply. 4.1.2.4 Back The shape and dimensions of the back shall meet an agreed drawing within the tolerances given in 7.

42、1.2. The vertical height of the back, dimension c of Figure 1, shall be greater than the vertical height of the front by not less than 6 mm when a water check is formed on the back, or 15 mm when there is no water check. EN 612:2005 (E) 8 4.2 Down-pipes The shape and dimensions of down-pipes are def

43、ined by the quantity of rainwater to be drained away and by architectural design requirements. Preferred shapes are circular and square. Other shapes shall be in accordance with an agreed drawing supplied by the purchaser. Key a front height b bottom width c back height d bead dimension (diameter or

46、 or class Y according to their bead diameter or equivalent modulus (see Table 1). If a product is identified as class X it will also comply with the requirements of class Y.
