Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 15877-3 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 155, Plastics piping systems and ducting systems, in collaboration with ISO Technical Committee
ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 2, Plastics pipes
and fittings for water supplies, in accordance with the Agreement on technical cooperation between ISO and
CEN (Vienna Agreement).
This part of ISO 15877 is part of a System Standard for plastics piping systems of a particular material for a
specified application. There are a number of such System Standards.
The System Standards are consistent with general standards on functional requirements and recommended
practices for installation.
This second edition cancels and replaces the first edition (ISO 15877-3:2003).

Introduction
The System Standard, of which this is Part 3, specifies the requirements for a piping system when made from
chlorinated poly(vinyl chloride) (PVC-C). The piping system is intended to be used for hot and cold water
installations and for heating system installations.
In respect of potential adverse effects on the quality of water intended for human consumption caused by the
product covered by this part of ISO 15877, the following are relevant.
a) This part of ISO 15877 provides no information as to whether the product may be used without restriction
in any of the Member States of the EU or EFTA.
b) It should be noted that, while awaiting the adoption of verifiable European criteria, existing national
regulations concerning the use and/or the characteristics of this product remain in force.
Requirements and test methods for materials and components, other than fittings, are specified in ISO 15877-
1 and ISO 15877-2. Characteristics for fitness for purpose (mainly for joints) are covered in ISO 15877-5.
ISO/TS 15877-7 gives guidance for the assessment of conformity.
This part of ISO 15877 specifies the characteristics of the fittings.

relevant requirements of ISO 15877-1.
4.2 Fitting material
The material from which the fittings are made shall be a chlorinated poly(vinyl chloride) (PVC-C) resin to which
are added those additives that are needed to facilitate the manufacture of fittings conforming to this part of
ISO 15877.

indicated parameters, test pieces shall withstand the hydrostatic (hoop) stress without bursting or leakage.
4.3 Evaluation of σ -values
LPL
The fitting material should be evaluated in accordance with ISO 9080 or equivalent, where an internal

NOTE 1 One equivalent way of evaluation is to calculate the σ -values for each temperature (e.g. for 20 °C, 60 °C
LPL
and 90 °C) individually.
Equation (1) and Equation (2) shall be used to determine the design stress, σ , in the fitting material (see
DF
Annex A of ISO 15877-2:2009), as well as the values of the hydrostatic stress, σ , of the fitting material

NOTE 2 The reference curves in Figure 1 for PVC-C Type I in the temperature range of 10 °C to 90 °C are derived
from Equation (1)
NOTE 3 The reference curves in Figure 2 for PVC-C Type II in the temperature range of 10 °C to 95 °C are derived
from Equation (2)
NOTE 4 Resistance to T of PVC-C Type I material is verified by testing in accordance with Annex A of
mal
ISO 15877-1:2009.
To demonstrate conformance to the reference lines, pipe samples shall be tested at the following
temperatures and at various hoop stresses such that, at each of the temperatures given, at least three failure
times fall in each of the following time intervals:
PVC-C Type I: Temperatures 20 °C; 60 °C to 70 °C; 90 °C;
PVC-C Type I: Time intervals 10 h to 100 h, 100 h to 1 000 h,1 000 h to 8 760 h and above 8 760 h;
PVC-C Type II: Temperatures 20 °C; 60 °C to 70 °C; 95 °C;
PVC-C Type II: Time intervals 10 h to 100 h, 100 h to 1 000 h, 1 000 h to 8 760 h and above 8 760 h;
In tests lasting more than 8 760 h, once no failure is reached at a stress and time at least on or above the
reference line, any time after that can be considered as the failure time. Testing should be carried out in
accordance with ISO 1167-1.
Design coefficients used for fitting materials are found in Annex A of ISO 15877-2:2009. Conformance to the
reference lines should be demonstrated by plotting the individual experimental results on the graph. At least
97,5 % of them should lie on or above the reference line.

No surface damage in the area of any injection point shall penetrate deeper than 20 % of the wall thickness, e, at any point. Outside
the area of any injection point, no surface damage shall occur. For sprue gating, the area of the injection point shall be calculated using
a radius R = 0,3d . For fittings moulded by end-gating techniques, e.g. ring or diaphragm methods, the gating area shall be a cylindrical
