by endorsement at the latest by June 2003 and confliting national standards shall be withdrawn at the latest by June 2003.
When transforming the European Prestandard ENV 10220 into this European Standard EN 10220. ECISS/TC 29regarded it as necessary to avoid any conflict with and to deviate as little as possible from ISO 4200:1991 because of the international trade in steel tubes and tubular products.
Table 2 of EN 10220 contains dimensions for heavy wall tubes that are not covered by ISO 4200:1991.
All parts of the European Standard series EN 10305 on steel tubes for precision applications contain tables withprefered dimensions that are specific for the various parts of the standards series and the products and fields of precision applications has bee unnecessary and has not been included in this standard.
This document supersedes ENV 10220:1993.
According to the CEN/CENELEC Internal Regulations the national standards organizations of the followingcountries are bound to impiement this European Standard:AustriaBelgium CzechRepublic Denmark FinlandSweden Switzerland and the United Kingdom.
1Scope
mechanical pressure and structural applications) the following:
- preferred dimensions for outside diameter and wall thickness in millimetres and
Technical Committees of ECISS and CEN should select these preferred dimensions for their product or functional standards where appropriate.
The outside diameters are classified into three series reflecting the availability of accessories for piping systems(see Clause 4). This classiication of outside diameters into different series and of preferred wall thicknesses indicates the range of steel tubes usually produced.
NOTEInformation ondimensions for steel tubes for special applications can be found in other European Standards e.g. prEN 10255 EN 10305 series EN ISO 11960 and EN ISO 11961 information on dimensions forstainless steel tubes in EN ISO 1127.

For the purpose of this European Standard the terms and definitions in prEN 10266 apply.
4Classification of outside diameters
The outside diameters given in Tables 1 and 2 are classified into three series which may be described in the following way:
standardized;- series 2: outside diameters for which not all accessories are standardized;
series 1: outside diameters for which all the accessories needed for the construction of piping systems are
--series 3: outside diameters for which very few standardized accessories exist.
NOTE 1 It is remended to select for tubes intended to be used as ponents of piping systems outside diameters from series 1 in Table 1. Tubes with outside diameters in aocordanoe with series 2 and 3 may not or not easily be available.
NOTE 2Acessories forheavy walltubes withdmensions inaocordance withTabie 2may not be available regardless of thoseries in Table 1 to which the relevant outside diameter is allocated.
