A note regarding hazard symbols and hazard pictograms in Annex A: Preferably a symbol shall be chosen which complies with the Regulation (EC) No. 1272/
8、2008 (Classification, Labelling and Packaging Regulation) (CLP) or according to the transitional provisions of this regulation one which complies with the Directive 67/548/EEC or Directive 1999/45/EC. Attention is drawn to the possibility that some of the elements of this document may be the subject
9、 of patent rights. DIN and/or DKE shall not be held responsible for identifying any or all such patent rights. Amendments The standard differs from DIN 2403:2007-05 as follows: a) explanatory notes regarding safe viewing distance have been included; b) the standard has been brought in line with the
10、changes in the identification of hazardous substances in Regulation (EC) No. 1272/2008 (CLP); c) the standard has been editorially revised. Previous editions DIN 2403: 1926-10, 1927-04, 1932-05, 1953x-12, 1965-03, 1984-03, 2007-05 DIN 2403:2014-06 4 1 Scope This standard specifies the identification
11、 of pipelines in aboveground installations according to the fluid conveyed. The identification of piping systems on ships and marine installations as specified in DIN ISO 14726, as well as pipeline identification specifications for other applications are not dealt with in this standard. A clear iden
12、tification of pipelines according to the fluid conveyed is essential for ensuring safety, correct maintenance operations, and effective firefighting, and is intended to bring attention to hazards in order to avoid accidents and damage to health. 2 Normative references The following documents, in who

17、 short text - or “hazard statement” - warns against the hazardous characteristics of materials 3.2 hazard statement a hazardousness characteristic attributed to a hazard symbol 3.3 hazard pictogram graphical composition that includes a symbol plus other graphic elements, such as a border, background
18、 pattern or colour, and is intended to convey specific information on the hazard concerned CLP-Regulation:2008, Article 2, Clause 3 DIN 2403:2014-06 5 4 Identification requirements 4.1 General Pipelines shall be clearly, legibly and permanently identified, according to the hazard estimation, at adeq
19、uate intervals along the pipe length and at points crucial to operation, e.g. at pipe ends and junctions, where the pipe passes through walls or floors, or near valves. In some cases, e.g. at pipe bends or where there is a close proximity of pipelines for conveying different fluids, adjustments may
20、need to be made to suit the ambient conditions. The requirements of this standard are based upon the simplified identification according to TRGS 201. The identification shall include: the basic colour and supplementary colour indicating the fluid conveyed, obtained from Table 1; the direction of flo
21、w, indicated by means of an arrow. Where the flow changes direction, both directions are to be indicated by arrows. Arrows for indicating direction of flow shall be in the lettering colour specified in Table 1; the fluid being conveyed expressed as text, a code or abbreviation, or chemical formula (
22、referred to below as the “legend”). This information shall be in the lettering colour specified in Table 1. When using codes or abbreviations, an explanation of the code or abbreviation used shall be posted or otherwise displayed at locations crucial to operation; if the fluids conveyed are deemed h
23、azardous substances in accordance with the Chemikaliengesetz (ChemG - German Act on the Protection Against Hazardous Substances (German Chemicals Act): the hazard symbols and hazard statements or hazard pictograms as in Annex A. The identification can be further supplemented (e.g. with the pressure,
24、 temperature or other characteristics by means of letter symbols as in DIN 1304-1). 4.2 Allocation of colours to pipe contents The fluids conveyed through pipelines are divided into 10 groups according to their general properties; the relevant colours for each group are given in Table 1.

28、, or plastic, metal or enamel plates). The alternative most suitable to ambient conditions, particularly as regards the safe viewing distance, shall be selected. The identification shall always be clearly and permanently applied or marked. It shall be made of materials that are resistant to the ambi
29、ent conditions at the location at which it is applied or marked. 5.2 Arrangement of information within the identification 5.2.1 Arrangement of general information The basic and supplementary colours form the basis of each identification. The legend and the flow direction arrow shall only be presente
30、d in the basic colour section, centred, either one below the other or side by side. For clearer presentation, the legend and flow direction arrow can be separated, either by a vertical line (when placed side by side, see Figures 5 to 7) or a horizontal line (when placed one below the other, see Figu
31、re 8); the line shall be in the lettering colour. DIN 2403:2014-06 7 5.2.2 Arrangement of supplemental information Hazard symbols or hazard pictograms shall be placed beside the flat side of the arrow which is not pointing in the direction of flow (i.e. they shall not be placed beside the point of t
32、he arrow). For clearer presentation, the hazard symbols and hazard pictograms may be separated from the legend by means of a vertical line in the lettering colour (see Figures 6 and 7). Any additional texts, graphical symbols or formulas are to be placed directly after or directly underneath the leg
33、end, in the latter case centred. 5.3 Identification by means of painting and lettering or tapes/bands The identification shall encompass the entire circumference of the pipe. The ends of self-adhesive bands or tapes shall overlap to secure them. If identification across the entire circumference of t
34、he pipe is not possible, the marking may be shortened. The layout of information is determined by the required safe viewing distance and the associated size of lettering (see 5.5). 5.4 Identification by means of labels, signs or plates Labels, signs and plates may have a border in the relevant lette
35、ring colour given in Table 1. The size of the identification is determined by the required safe viewing distance and the associated size of lettering (see 5.5). 5.5 Design principles, dimensions, safe viewing distance and size of lettering The size of the identification is determined by the required
36、 safe viewing distance and the resulting size of lettering, and on the length of the legend. To determine the safe viewing distance, use the following equation: ZhE = where E is the safe viewing distance; h is the size of lettering; Z is the factor of distance. For letters and numbers Z = 300, for h
37、azard symbols and hazard pictograms Z = 40 (see DIN 1450). The equation applies to an illuminated surface and for reading distances up to 25 m. To determine the safe viewing distance for the hazard symbols and hazard pictograms, the lateral length “a” is to be used. Lettering as in DIN 1451-1 and DI
38、N 1451-2 shall be used. DIN 2403:2014-06 8 When determining the size of the identification, the following requirements shall be taken into consideration: the ratio of the width of the basic colour panel to that of the supplementary colour panel(s) should be 2 : 1; the identification shall be at leas
39、t 75 mm wide; lettering shall be at least 5 mm high; the flow direction shall either be indicated by a pointed end of the label or as a symbol as in Figure 1 in accordance with ISO 7000. When using the arrow symbol as in ISO 7000, the point of the arrow shall be at least at 1/3 the lettering height;
40、 Figure 1 Arrow showing flow direction (ISO 7000-0251, functional arrow; group select) arrows may be either the basic colour or lettering colour; the width of any borders shall be 0,025 b (b = height of the marking or label/sign); when applying markings directly to the pipe, the maximum area of the
41、marking shall be 79,57 % of the pipe diameter, which means that when applying the marking to the entire pipe circumference the information is repeated at least 4 times, so that the marking is legible from all points of observation; when using hazard symbols and hazard pictograms, the safe viewing di
42、stance of the entire identification will always be determined based on the safe viewing distance for the hazard symbols and hazard pictograms. For explanatory notes regarding safe viewing distance, see Figures 2 to 4. Figure 2 Identification with text h = 17 mm This results in the safe viewing dista

44、ults in the safe viewing distance (E): E = 2,7 mm 300 = 0,81 m The safe viewing distance for the entire identification is equal to the safe viewing distance for the smallest element within the identification and therefore amounts to 0,8 m. Figure 4 Identification with hazard pictogram and text h1= 1
45、7 mm This results in the safe viewing distance (E): E = 17 mm 300 = 5,1 m a = 20 mm This results in the safe viewing distance (E): E = 20 mm 40 = 0,8 m The safe viewing distance for the entire identification is equal to the safe viewing distance for the smallest element within the identification and
46、 therefore amounts to 0,8 m. The safe viewing distance for the arrow indicating the flow direction is the same as the safe viewing distance of the text, based upon the premise that the point of the arrow is at least 1/3 the lettering height.
