(ABS) —

Part 1: Specifications for pipes, fittings

and the system

The European Standard EN 1455-1:1999 has the status of a

British Standard

ICS 23.040.01; 83.140.30; 91.140.80

This British Standard, having

been prepared under the

direction of the Materials and

Chemicals Sector Policy and

Strategy Committee, was

published under the authority

of the Standards Policy and

BS 5255:1989 will be declared obsolescent with effect from 2001-06-30

NOTE In the UK this date is being applied to coordinate the change-over to European Standards for plastics piping systems for this application and any consequent revision, declaration of obsolescence or withdrawal of the corresponding British Standards which are being superseded.

Products conforming to BS EN 1455-1 will be compatible with those of the same size in accordance with BS 5255:1989 The nominal sizes DN/OD 36, 43 and 55 correspond exactly with the 1¼, 1½ and 2 sizes respectively in BS 5255:1989

Since EN 1455-1:1999 does not cover all the piping components covered by or used in conjunction with products conforming to BS 5255, see BS 4514:1983 and its planned revision for the UK requirements for the minimum opening dimensions of access fittings, design of swept fittings, for connectors to WC pans and stand-off dimensions of pipe and fitting clips

The UK participation in the preparation of EN 1455-1:1999 was entrusted by Technical Committee PRI/61, Plastics piping systems and components, to Subcommittee PRI/61/1, Thermoplastics piping systems and components for non-pressure applications, which has the responsibility to:

A list of organizations represented on this committee can be obtained on request to its secretary

The responsible UK committee gives the following advice concerning the selection of alternative test conditions provided in this standard

a) Table 17, as referred to in 8.1, appears to present two alternative test conditions,

i.e method A or method B of EN 743:1994, without identifying where they apply or which is the reference method in case of dispute Since these alternative test conditions might lead to conflicting results, users of this standard should declare or agree on a contractual basis which condition is to be the reference condition in case of dispute

b) In Table 21, reference is made to a specific point of detail in the current edition of

EN 921, i.e “types a or b” end caps, and therefore:

1) the reference should be construed as relating to the current (1995) edition, as

though the reference in Table 21 and hence also in clause 2, was dated accordingly;

2) since alternative test conditions are permitted which might lead to conflicting results, depending on the choice of end caps, users of this standard should declare

or agree on a contractual basis which condition is to be the reference condition in case of dispute

The responsible UK committee gives the following advice concerning the specification of piping components used with piping systems conforming to this British Standard but not detailed in EN 1455-1:1999

— aid enquirers to understand the text;

— present to the responsible international/European committee any enquiries

on the interpretation, or proposals for change, and keep the UK interests informed;

— monitor related international and European developments and promulgate them in the UK

Amendments issued since publication

13818 Corrigendum No 1 30 October 2002 Revision of national foreword

c) See BS 4514:2001 for the UK requirements for the minimum opening dimensions of access fittings, design of swept fittings, connectors to WC pans, stand-off dimensions of pipe and fitting brackets and requirements for adaptors and plugs Reference should

also be made to the following design requirements of BS 4514:2001, 5.3.1, 5.3.3, 5.3.5,

5.3.7, 5.3.8, 5.3.9, and Figures 6, 8 and 9.

Analogous provisions apply in Scotland and Northern Ireland

d) For external installation, which is commonplace and remains allowed in the UK,

EN 1455-1:1999 only requires that additional requirements depending on the climate

be agreed between the manufacturer and the user (in clause 14: otherwise, in line with

European practice, EN 1455-1:1999 only gives specific requirements for products for discharge systems intended to be installed within buildings.) If the product is to be installed externally, it may require protection by painting or some other means.The responsible UK committee gives the following advice concerning the selection and installation of piping systems and components conforming to this British Standard.e) The products should only be used in application area B, i.e suspended from brackets above ground and installed in accordance with BS 5572 using the N socket variants as specified

For external installation, see item d) of this foreword The advice of the manufacturer

of products conforming to BS EN 1455-1 should be sought accordingly

f) In respect of fire regulations (see 4.4), for England and Wales The Building Regulations 1991, Approved Document B3, Section 10 requires that where ABS pipe

with an internal diameter greater than 40 mm (1½”) penetrates a fire wall, floor or enclosure the point of penetration is protected by a proprietary fire seal This seal must

be certificated by third party testing to show that it is effective with ABS pipes.Analogous provisions apply in Scotland and Northern Ireland respectively

Editorial note: Reference to regulations

In 4.4 the only “requirement” is that “pipes and fittings shall conform to any relevant requirements

on fire regulations” Since the authority for such requirements lies with national regulators and not with standards organizations, which do not have the power to waive regulations even should they so wish, this type of information in standards should be presented as a note, or as a statement in a foreword or introduction As information it can refer in general or specific terms to the existence of current regulations/legislation/directives applicable to the products or the conditions of their use The expression here as part of the normative text is inappropriate and should not be considered an acceptable precedent for other standards to follow.

Warning This British Standard, which is identical with EN 1455-1:1999, does not

necessarily detail all the precautions necessary to meet the requirements of the Health and Safety at Work etc Act 1974 Attention should be paid to any appropriate safety precautions and the test methods referred to in EN 1455-1 should be operated only by trained personnel

6.4 Dimensions of sockets and pipe ends

6.4.1 Classification and designation of sockets

The sockets shall be classified according to the joint type where they are intended to be used for The types

of sockets are ring seal sockets, solvent cement sockets or sockets for dual purpose

6.4.1.1 Ring seal sockets

The lengths of ring seal sockets of type S, type N and type L and of spigot ends are designed for differentpipe lengths

- Type S (short): This socket type may be used as an expansion joint system where the length of a pipe

does not exceed 2 m When this socket form is part of a fixed-joint system (i.e systems which do not inthemselves allow for expansion and contraction), it shall be used in conjunction with a type L (long)socket, as specified in this standard

- Type N (normal): This socket type may be used as an expansion joint system When this socket form is

part of a fixed-joint system (i.e systems which do not in themselves allow for expansion and contraction),

it shall be used in conjunction with a type L (long) socket, as specified in this standard The values for the

length of engagement, A, given in Table 6 or Table 7, as applicable, are related to a pipe length of 3 m for

use inside buildings

- Type L (long): This socket type may be used as an expansion joint in fixed-joint systems (i.e systems

which do not in themselves allow for expansion and contraction) whether jointed by ring seal or solventcement or for use with type S and type N sockets, as applicable where the length of pipe exceeds thegiven maximum for those types

6.4.1.2 Solvent cement sockets

- Type CS (short type for solvent cement joints): This socket type may be used where jointing is carriedout by an approved manufacturer under controlled conditions

6.4.1.3 Dual purpose sockets

This socket is intended to be used for a connection either made by means of a sealing ring or by solventcement which has to be applied after removal of the sealing ring, if any

Type S and type N sockets (see 6.4.1.1) may be used for dual purpose configuration.

EN 1455-1:1999

6.4.2 Dimensions of ring seal sockets and spigot ends

6.4.2.1 Diameters and lengths

The diameters and lengths of ring seal sockets and spigot ends (see Figure 3, Figure 4, Figure 5 or Figure 6)shall conform to

- Table 5 for type S and dual purpose (see Figure 4), or to

- Table 6 or Table 7, as applicable, for type N and dual purpose (see Figure 4), or to

- Table 8 for type L (see Figure 5)

and shall be in accordance with the following conditions:

a) where sealing rings are firmly retained, the dimensions for the minimum value for A and the maximum value for C shall be measured to the effective sealing point (see Figure 6 as an example) This point

shall give a full sealing action;

b) where sealing rings are firmly retained, requirements for dimension B (see Figure 4 or Figure 5) do

not apply

Different designs of ring seal sockets (see Figure 4 or Figure 5) are permitted, provided the joints conform to

the requirements given in clause 9.
