Foreword
This document EN 13349:2002 has been prepared by Technical Committee CEN/TC 133 "Copper and copper
alloys", the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by February 2003, and conflicting national standards shall be withdrawn at the latest
by February 2003.
Within its programme of work, Technical Committee CEN/TC 133 requested CEN/TC 133/WG 3.1 "Copper tubes"
to prepare the following standard:
EN 13349, Copper and copper alloys — Pre-insulated copper tubes with solid covering.
This is one of a series of European Standards for copper and copper alloy tubes. Other products are specified as
follows:
EN 1057, Copper and copper alloys — Seamless, round copper tubes for water and gas in sanitary and heating
applications.
EN 12449, Copper and copper alloys — Seamless, round tubes for general purposes.
EN 12450, Copper and copper alloys — Seamless, round copper capillary tubes.
EN 12451, Copper and copper alloys — Seamless, round tubes for heat exchangers.
EN 12452, Copper and copper alloys — Rolled, finned, seamless tubes for heat exchangers.
EN 12735-1, Copper and copper alloys — Seamless, round copper tubes for air conditioning and refrigeration —
Part 1: Tubes for piping systems.
EN 12735-2, Copper and copper alloys — Seamless, round copper tubes for air conditioning and refrigeration —
Part 2: Tubes for equipment.
EN 13348, Copper and copper alloys — Seamless, round copper tubes for medical gases or vacuum.
EN 13600, Copper and copper alloys — Seamless copper tubes for electrical purposes.
Annex A is normative.
According to the CEN/CENELEC Internal 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, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden,
Switzerland and the United Kingdom.
Introduction
It is recommended that tubes manufactured to this standard are certified as conforming to the requirements of this
standard based on continuing survaillance which should be coupled with an assessment of a supplier's quality
system against the appropriate standard, i.e. EN ISO 9001.
1 Scope
This European Standard specifies the requirements, sampling, test methods and conditions of delivery for seamless
round copper tubes covered with solid plastics material.
It is applicable to tubes intended for:
– distributing networks for hot water and cold water;
– hot water heating systems (temperature not exceeding 95 °C) including underfloor heating systems;
– domestic gas and liquid fuel distribution.
NOTE  The primary purpose of the covering is to protect the copper tube against external corrosion in service. In addition, the
covering can give some protection against impact and mechanical loading during transportation, installation and operation.
Coverings whose primary objective is thermal insulation are not included in this standard.
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
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references, the latest edition of the
publication referred to applies (including amendments).
