34、re.For the purposes of this standard, components are pipes, fittings, joints and seals.This standard is for components used for the discharge of: domestic waste water; surface water; and groundwater.This standard is also for components discharging other waste water (e.g. industrial waste water), as
35、long as it does not damage the components or endanger the health and safety of personnel.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the pub

42、ngs are made of precision steel tube of austenitic stainless steels, manufactured generally of material No. 11 ISO 683-13:1986, No. 19a ISO 683-13:1986 and No. 21 ISO 683-13:1986. Comparable materials are permissible.Until a European Standard for as-welded precision steel pipes is produced, national
43、 specifications remain available for the testing of steel pipe before finished into pipes and fittings for drainage.The choice of the material depends on the application (see ISO 683-13:1986, EN 10088-2). The steel tube from which the pipes and fittings are made shall be of the materials specified i
44、n the first paragraph.Prefabricated components are assembled at the manufacturers plant. They shall be designed so as to function permanently and be interchangeable.5 DimensionsThe dimensions shall comply with EN 1124-2 or EN 1124-3.5.1 Socket shapeThe socket shape shall comply with EN 1124-2 or EN
45、1124-3.5.2 Nominal sizesThe nominal sizes for pipes and fittings to EN 1124-2 shall be in the range of DN/OD 50, 75, 110 and 160. The nominal sizes for pipes and fittings to EN 1124-3 shall be in the range of DN/ID 40, 50, 70, 80, 100, 125, 150 and 200.6 Requirements of pipes and fittings6.1 Straigh
46、tnessThe pipes shall be straight. In the pipe axis, the bend over a length of 1 m shall not be more than 1,5 mm.6.2 Ends of pipes and fittingsThe pipes and fittings shall be cut perpendicular to the pipe axis. For fittings up to DN/OD 110 or DN/ID 100 a variation of the right angle of up to 3 is all
47、owed. For the ends of pipes and fittings with a nominal size larger than DN/ID 100 or DN/OD 110, the deviation of the right angle shall not be more than 1 45. All burrs shall be removed.6.3 Inner surface finishThe inner surface shall be smooth and free from cracks and defects affecting flow. The inn
48、er surface of sockets shall be free from sharp irregularities and shall meet the requirements given in 6.4. Both requirements also apply to the weld area.There shall be no visible annealing colour or material impurities.6.4 Outside surface finishThe outside surface shall be smooth and free from shar
49、p irregularities which could damage the seals during insertion.There shall be no visible annealing colour or material impurities.6.5 RoundnessThe permissible variations of the pipe diameter according to Table 4 of EN 1124-2:1999 or Table 5 of EN 1124-3:1999 shall be satisfied.EN 1124-1:1999 BSI 6 March 200676.6 WeldsBurrs, edges and lugs in the weld area shall be avoided. Welding burrs or inclusions shall be so small that acceptable post-treatment is possible by pickling.The inner burr of the lon
