Out of roundness (ovality) is calculated in accordance with ISO 11922-1.
7.3 Wall thicknesses and their tolerances
Table 2 provides maximum allowable pressure (PS) values for pipes with and without integral socket.
Pipes with integral sockets are derated to account for the socket strength. Minimum wall thicknesses
shall be in accordance with Table 2. Values shown in Table 2 do not include a non-glass-filled layer
of outer and inner polyethylene, minimum 1,5 mm each, for protecting against UV and chemical
degradation (see also Annex C).
Alternatively, other diameters and pressures may be used; the corresponding wall thickness is then
calculated according to the national requirements.
The PS values in Table 2 are based on the value C = 1,60, where C is the design coefficient. Higher design
coefficients may be agreed upon between the manufacturer and the purchaser. See Annex A.

Introduction
The pipe systems which consist of pipes produced by adding short glass fibres into high density
polyethylene resins are called polyethylene reinforced with short glass fibres (PE-sGF) piping systems.
The physical and mechanical properties are influenced by short glass fibre orientation. This document
is applicable to pipe inside diameter from 200 mm to 2000 mm with integrated socket and spigot fusion
joint. The PE-sGF system is intended to be used for general purpose fluids supply (e.g.: chemical plants,
industrial sewerage engineering, power plants, agricultural production plants, water treatment).
For the material subject of this document the mechanical performances are obtained on the basis of
standards dedicated to thermoplastics, the geometrical characteristics are defined exclusively for this

5 Material
The material from which the pipe is made shall be in accordance with ISO/CD 22101-1.
6 General characteristics
6.1 Appearance
When viewed without magnification the internal surfaces of pipes, sockets and spigots shall be

The dimensions of the pipe, of the socket length of the pipe for welding, and of the integrated spigot
length shall be measured in accordance with ISO 3126, where applicable. In the case of dispute the
measurements of dimensions shall be made not less than 24 h after manufacture after being conditioned
for at least 4 h at (23±2 ) °C.

Tolerances for intermediate are calculated based on the following formula, rounding calculated values down to the
nearest 1 mm: d =d +(d ∙ 0,017) but ≧d + 8 mm.
im,max in in in
b
Out of roundness (ovality) is calculated according to ISO 11922-1.
7.3 Wall thicknesses and their tolerances
Minimum wall thicknesses, listed in Table 2, are not including non-structural layer of outer and inner
polyethylene, minimum 1,5 mm each for colouring, protection against UV and chemical degradation.
Alternatively other diameters and pressures may be used; the corresponding wall thickness is then
calculated according to the applicable formula.
The PN values in Table 2 are based on C=1,60. Higher safety coefficients may be agreed upon between
the manufacturer and the purchaser, see also Annex B.
