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 3.

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 International Standard may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 15493 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport

of fluids, Subcommittee SC 3, Plastics pipes and fittings for industrial applications.

This document has been prepared under a mandate given by the European Commission and the European Free

Trade Association and supports essential requirements of EU Directives.

At the date of publication of this International Standard, the following standards had been published for piping

systems, used for industrial applications, made from other types of plastic:

ISO 10931 (all parts), Plastics piping systems for industrial applications — Poly(vinylidene fluoride) (PVDF)

ISO 15494, Plastics piping systems for industrial applications — Polybutene (PB), polyethylene (PE) and

polypropylene (PP) — Specifications for components and the system — Metric series.

3 Terms and definitions

For the purposes of this International Standard, the terms and definitions given in ISO 472 and ISO 1043-1 and the

following apply.
3.1 Geometrical definitions

NOTE The symbols d and e correspond to d and e given in other International Standards such as ISO 11922-1.

e ey y
3.1.1
nominal outside diameter

specified outside diameter of a component, which is identical to the minimum mean outside diameter, d , in

em,min
millimetres

NOTE The nominal inside diameter of a socket is equal to the nominal outside diameter of the corresponding pipe.

3.1.2
outside diameter at any point

outside diameter measured through the cross-section at any point on a pipe, or the spigot end of a fitting, rounded

up to the nearest 0,1 mm
3.1.3
mean outside diameter

measured length of the outer circumference of a pipe, or the spigot end of a fitting, divided by π (≈ 3,142), rounded

up to the nearest 0,1 mm
3.1.4
mean inside diameter of a socket
arithmetic mean of two measured inside diameters perpendicular to each other
3.1.5
nominal size of flange

numerical designation for the size of a flange for reference purposes, related to the manufactured dimension in

millimetres
3.1.6
out-of-roundness

difference between the measured maximum outside diameter and the measured minimum outside diameter in the

same cross-sectional plane of a pipe, or the spigot end of a fitting, or the difference between the measured

maximum inside diameter and the measured minimum inside diameter in the same cross-sectional plane of a

socket
3.1.7
nominal wall thickness
wall thickness, in millimetres, corresponding to the minimum wall thickness, e
min
3.1.8
wall thickness at any point

measured wall thickness at any point around the circumference of a component, rounded up to the nearest 0,1 mm

ISO 15493:2003(E)
3.1.9
pipe series

dimensionless number related to the nominal outside diameter, d , and the nominal wall thickness, e

n n

NOTE 1 The pipe series S is related to the pipe geometry as shown in equation (1):

de−
S = (1)
NOTE 2 Flanges are designated on the basis of PN.
3.1.10
standard dimension ratio
SDR

ratio of the nominal outside diameter, d , of a pipe to its nominal wall thickness, e

n n

NOTE In accordance with ISO 4065, the standard dimension ratio SDR and the pipe series S are related as shown in

equation (2):
SDR = 2S + 1 (2)
3.2 Definitions of materials
3.2.1
virgin material

material in a form such as granules or powder that has not been previously processed other than for compounding

and to which no reprocessable or recyclable materials have been added
3.2.2
reprocessable material

material prepared from clean unused rejected pipes, fittings or valves, produced in a manufacturer's plant by a

process such as moulding or extrusion, which will be reprocessed in the same plant and for which the complete

formulation or material specification is known

NOTE 1 Such material may include trimmings from the production of such pipes, fittings and valves.

NOTE 2 In the case of valves, only those thermoplastics parts which are made from material conforming to this International

Standard may be considered as reprocessable material.
3.3 Definitions related to material characteristics
3.3.1
lower confidence limit
LCL

quantity with the dimensions of stress, expressed in megapascals, which can be considered as a property of the

material and represents the 97,5 % lower confidence limit of the predicted long-term hydrostatic strength at a given

temperature, T, and time, t, determined by pressurizing internally with water
3.3.2
minimum required strength
MRS

value of σ at 20 °C and 50 years, rounded down to the next lower value in the R 10 series when σ is less

LCL LCL

than 10 MPa, or to the next lower value in the R 20 series when σ is greater than or equal to 10 MPa

LCL

NOTE The R 10 and R 20 series are the Renard number series as defined in ISO 3 and ISO 497.
