24、iven the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2004, and conflicting national standards shall be withdrawn at the latest by February 2004. Annexes A, B, C, D, E and F are normative. According to the CEN/CENELEC Internal
25、 Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spai

27、e internal surface for the reduction of friction of tubes and pipeline fittings for conveyance of non-corrosive gas. Other paints or paint systems are not excluded provided they comply with the requirements given in this standard. The coating consist of one layer of liquid product, normally shop app
28、lied onto abrasive blast cleaned steel by airless spray or conventional spray techniques. Brush application may be used only for repairs. The coating qualified in accordance with this standard is considered suitable for operating temperatures between 20 C and + 110 C. In this European Standard the w
29、ord “components“ is used for tubes and fittings. 2 Normative references This 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 publications are listed hereafter. For da

40、marks 3.5 roughness roughness parameter, Ry5 (roughness depth average of 5 successive evaluation areas), in micrometres EN ISO 8503-4:1995 4 Coating material 4.1 General The coating material is generally composed of two packs: base and hardener. The coating material shall not contain any substances
41、that will be released from the paint film after it is cured and are proven to be detrimental to the operations of the pipeline. The coating material shall be qualified in accordance with 4.2 and shall not be changed after qualification. The applied and cured paint film shall be smooth to obtain a re
42、duction in the friction. Unless otherwise agreed, the applied coating should provide a corrosion protection during storage and transport for a period of one year without significant breakdown of the paint film. 4.2 Qualification of coating materials 4.2.1 General This subclause describes the laborat
43、ory tests required for qualification of coating materials by the coating material manufacturer.

44、 and the tests reported shall be carried out on coating material and test panels (steel panels) that, unless otherwise specified, have been prepared and coated according to EN ISO 1513 and EN ISO 1514 and the requirements of the coating material manufacturer. The dry film thickness of the coating on
45、 the panels shall be measured in accordance with 4.2.8. Coating applied to glass and steel panels shall be conditioned in accordance with one of the following cycles, depending on the test method: cycle A; sample: glass panel; at (23 2) C with a relative humidity 80 %, until the coating is at least
46、“tack free“ (see 3.4); heat for 30 min in a circulating air oven at (75 5) C. cycle B sample: steel panel; at (23 2) C with a relative humidity 80 %, until the coating is at least “tack free“ (see 3.4); heat for 30 min in a circulating air oven at (150 5) C. Other conditioning cycles are allowed by
47、agreement.
