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by endorsement, at the latest by February 2003, and conflicting national standards shall be withdrawn at the latest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).

applications.

3 Terms and definitions
For the purposes of this standard, the following terms and definitions apply.
3.1
seamless round copper tube
hollow semi-finished product, circular in cross-section, made of copper, having a uniform wall thickness, which at all
stages of production has a continuous periphery, supplied in straight lengths or in coils
3.2
solid plastics covering
seamless, continuous and externally smooth co-extruded layer of solid plastics material, fitting to the outer surface
of a seamless round copper tube. Solid plastics material includes expanded plastics covering material for which the
ratio of its specific mass to the specific mass of the basic plastics material is greater than 50 %
3.2.1
plain solid plastics covering
covering of non-expanded plastics material with uniform thickness
3.2.2
profiled solid plastics covering
covering of non-expanded plastics material profiled on its inner surface to provide channels which form gaps
between the plastics material and the copper tube
3.2.3
alveolar solid plastics covering
covering of expanded plastics material for which the ratio of its specific mass to the specific mass of the basic
plastics material is greater than 50 %, with uniform thickness
3.3 covering thickness
3.3.1
nominal overall thickness
half the difference between the nominal outside diameter of the covering and the nominal outside diameter of the
copper tube
3.3.2
bottom-wall thickness (profiled covering)
difference at any point between the overall thickness and the depth of the internal channels
3.4
production batch
definite quantity of products of the same form, the same temper and the same cross-sectional dimensions
manufactured during the same production sequence under uniform conditions
4 Designations
4.1 Temper
For the purposes of this standard, the following designation, which is in accordance with the system given in
EN 1173, applies for the temper of the copper tube which conforms to EN 1057:
R. Temper designated by the minimum value of tensile strength requirement for the copper tube with mandatory
tensile strength and elongation requirements.
4.2 Product
The product designation provides a standardized pattern of designation from which a rapid and unequivocal
description of a product is conveyed in communication. It provides mutual comprehension at the international level
with regard to products which meet the requirements of the relevant European Standard.
The product designation is no substitute for the full content of the standard.
The product designation for products to this standard shall consist of:
– denomination (Pre-insulated copper tube);
– number of this European Standard (EN 13349);
– copper tube temper designation (see EN 1057);
– copper tube nominal cross-sectional dimensions: outside diameter × wall thickness;
– covering type [plain solid plastics covering (PLN), profiled solid plastics covering (PRF), alveolar solid plastics
covering (ALV)].
EXAMPLE  Pre-insulated copper tube conforming to this standard, in temper R220 (annealed), copper tube nominal outside
diameter 12 mm, nominal wall thickness 1,0 mm, with profiled solid plastics covering, shall be designated as follows:
5 Ordering information
In order to facilitate the enquiry, order and confirmation of order procedures between the purchaser and the supplier,
the purchaser shall state on his enquiry and order the following information:
a) quantity of product required (in metres);
b) denomination (Pre-insulated copper tube);
c) number of this European Standard (EN 13349);
d) copper tube temper designation (see EN 1057);
e) copper tube nominal cross-sectional dimensions: outside diameter × wall-thickness (see EN 1057);
