4.2 Long term regression testing
The manufacturer shall provide at least one full regression curve as per ASTM D2992 as modified in
this subclause and in 5.1. The regression curve shall be at 65 °C or higher for GRE and 21 °C or higher for
GRUP or GRVE.
The manufacturer’s gradient from the full regression curve shall be compared with the values in
Table A.1 and a gradient can be selected per the process in Annex A.
NOTE 1 The one full regression curve does not have to be at or above the design temperature of the project.
For example, the enquiry sheet specifies a design temperature of 93 °C and the manufacturer has a full regression
curve at 85 °C for GRE-Aliphatic Amine. Since the resin matrix is GRE and the temperature of the full regression
curve is above 65 °C, the data are acceptable. On the other hand, validation of the long term envelope via survial
tests would have to be performed at the design temperature of the project.
The manufacturer shall conduct the long term regression on either a plain pipe or a pipe+joint, for one
pipe diameter only, the diameter to be determined by the manufacturer.
NOTE 2 For economical and practical reasons, long term regression testing is typically conducted on small
diameters. The recommended minimum pipe size is DN50. Data seems to be more consistent as the size increases
(i.e. DN100 test results seem to be more consistent than DN50 test results).
4 © ISO 2017 – All rights reserved

ISO 14692-2:2017(E)
The D /t ratio of the pipe size shall be within the range of published D /t ratios that are
r,min r,min r,min r,min
to be qualified. Ideally, the D /t ratio of the pipe size should be close to the average D /t
r,min r,min r,min r,min
ratio of all of the pipe sizes to be qualified. It is not desirable to have the D /t ratio of the pipe
r,min r,min
size at either extreme.
The test fluid shall be potable water. For testing completed prior to the publication of this document,
the test fluid may be salt water. In this case, the salt content shall be specified and shall not be greater
than 35 g/L. The intention of this requirement is to allow validation of existing test data, but to require
potable water for future testing. Potable water is a more aggressive test medium than salt water. Test
data using mineral oil should be rejected since mineral oil is not a degrading agent to the bond between
the glass fibres and the resin matrix.
All tests shall be conducted with unrestrained (i.e. "free") ends.
4.3 Gradient, G
xx
The manufacturer shall declare gradient, G , in accordance with Annex A.
xx
4.4 MPR
xx
MPR shall be defined in accordance with ISO 14692-1:2017, 4.1.
xx
For design temperatures in excess of 65 °C for GRE and 21 °C for GRUP and GRVE, the manufacturer
shall also publish MPR at the design temperature or higher.
xx
The following shall be taken into account:
a) Default temperatures are 65 °C (MPR ) for GRE and 21 °C (MPR ) for GRVE and GRUP. For clarity,
65 21
MPR shall always be published with a temperature subscript (e.g. MPR or MPR , not MPR).
65 21
b) The default temperature for GRE is established at 65 °C since this temperature is at or above
the design temperature for many typical GRE applications and since many manufacturers have
conducted qualification testing for pressure at this temperature.
c) The default temperature for GRUP is established at 21 °C since there are many applications for GRUP
near ambient temperature and the amount of qualification testing for pressure by manufacturers
at 65 °C is less than that at 21 °C to 50 °C.
d) GRVE can be suitable for applications at temperatures above 65 °C. However, the amount of
qualification testing for pressure above 65 °C by manufacturers is very small. Like GRUP, there is
more qualification data between 21 °C to 50 °C, thus the default temperature for GRVE is established
at 21 °C.
e) The manufacturer uses the survival tests to validate MPR (see 5.3.1).
xx
4.5 Partial factors
4.5.1 Partial factor for design lifetime, A
The partial factor for design lifetime, A , is specified in ISO 14692-3:2017, 6.1.1.
4.5.2 Partial factor for chemical degradation, A
The partial factor for chemical degradation, A , shall be 1,0.
NOTE 1 It is the resin rich liner, not the structural cage, that is designed to prevent chemical degradation. A
partial factor applied to the reinforced wall thickness would provide little to no value in preventing chemical
degradation.
ISO 14692-2:2017(E)
NOTE 2 Water permeates thermoset resins quite quickly. The silane coupling agent is the key component
providing resistance to breakdown from water attack. Without the silane coupling agent, water permeation
would occur followed by a breakdown of the bond between the glass and resin followed by etching of the fibers
and finally fiber failure.
NOTE 3 While the silane coupling agent provides resistance to breakdown from water attack, other chemicals
can attack the bond between the resin and the glass reinforcement. Some of these chemicals include strong acids
and bases such as sodium hydroxide. It is these chemicals that require a resin-rich, reinforced liner of sufficient
thickness to protect the structural layers from permeation of these chemicals and attack of the bond between
the glass and the resin. Most of these chemicals do not permeate quickly, so practical liners are possible. Other
standards, such as ASTM D3681 or EN 13121-2, can be suitable as a qualification programme to predict the
thickness of the liner based on exposure to various chemicals in a stressed condition.
4.5.3 Partial factor for cyclic loading, A
The partial factor for cyclic loading, A , is specified in ISO 14692-3:2017, 6.1.3.
4.6 Long term envelope data points
The manufacturer shall declare and demonstrate the long term envelope data points (σ ,
h,LT,2:1,xx
σ , σ , σ , σ , σ , σ and σ ) and the threshold
a,LT,2:1,xx h,LT,0:1,xx a,LT,0:1,xx h,LT,Rtest,xx a,LT,Rtest,xx a,LT,0:-1,xx h,LT,1:0,xx
envelope data points (σ , σ , σ , σ , σ and σ ) by testing in
h,thr,2:1, a,thr,2:1, h,thr,Rtest, a,thr,Rtest, a,thr,0:-1, h,thr,1:0
accordance with Annex B. The threshold envelope data points do not have a temperature subscript as
the threshold is defined, by default, at 65 °C for GRE and 21 °C for GRUP and GRVE.
Long term envelope data points are defined at temperatures. To calculate a long term envelope data
point, survival tests on pipe(s), joint(s) and fitting(s) are required at the design temperature (or higher)
in accordance with Annex C.
4.7 Dimensions
The manufacturer shall declare the following dimensions:
a) DN;
b) ID;
c) D and t ;
r,min r,min
d) t ;
l
e) laying lengths;
f) bend radii (for elbows).
The nominal diameter should be agreed between the manufacturer and principal.
4.8 Baseline values
The manufacturer shall declare basline values for quality control puposes for the following:
a) degree of cure;
b) barcol hardness (GRUP and GRVE only);
c) glass content.
The manufacturer shall select samples from standard production to determine the baseline values.
Samples for baseline testing should be taken from standard production to ensure that results are being
obtained across the entire standard deviation of the population. Samples for baseline testing should

ISO 14692-2:2017(E)
not be limited to the 1 000 h qualification samples since these samples can be anywhere within the
standard deviation of the population.
4.9 Flexibility factors and SIFs
The manufacturer shall declare flexibility factors for bends in accordance with ISO 14692-3:2017, 7.4.
The manufacturer shall declare SIFs for bends and tees in accordance with ISO 14692-3:2017, 7.5.
4.10 Production processes and jointing instructions
The manufacturer shall declare general production processes and jointing instructions sufficient to
verify that the scaling rules in Annex F have been met. Proprietary processes need not be disclosed.
5 Qualification programme
5.1 General
The qualification programme is a one-time process. If the manufacturer has test data from a previous
project, the manufacturer may have the option to use this data on other projects. However, the
principal may also have the option to require one or more of the tests in Table 1 to be conducted for
their particular project. These tests shall be specified on the enquiry sheet (refer to ISO 14692-1:2017,
Annex D). The principal may also have the option, via the enquiry sheet in ISO 14692-1:2017, Annex D, to
specify which tests, if any, shall be conducted by a laboratory that meets ISO/IEC 17025.
The qualification programme shall be based on a standard design life of 20 years. A shall be used to
scale the design envelope to other design lives. A shall not be greater than 1,0.
The test fluid for the qualification procedure for pressure and temperature shall be potable water. See
also 4.2 for a clarification of the test fluid.
All tests involving internal pressure shall be conducted with unrestrained (i.e. "free") ends.
Table 1 provides a summary of the qualification programme. Figure 2 shows a flowchart of the
procedure for product qualification. Figure 3 shows a flowchart of the procedure for determining
elastic properties.
Permanent repair procedures shall be qualified according to this qualification programme.
NOTE The manufacturer's repair procedures that only involve qualified components may not need any
additional qualification.
When joints are qualified, the joint shall be made in accordance with the manufacturer's declared joint
instructions. This qualifies both the joint and its joint instructions.
ISO 14692-2:2017(E)
Continued from Figure 1, Clause 4
Manufacturer selects pipe sizes and
pressure classes to validate the long
term envelopes (Annex E)
Manufacturer conducts survival
tests to validate the long term
envelopes (5.3.1 and Annex C) at or
above the design temperature
required for the piping system
This option allows the manufacturer to validate
the long term envelope at other temperatures. If
Optional: Manufacturer conducts this option was not performed, then the long
survival tests at other temperatures term envelope at ambient temperature would be
the same as the long term envelope at the design
temperature.
Manufacturer uses scaling rules to
qualify sizes/pressure classes that
are not tested (6.2 and Annex D)
Manufacturer conducts tests for
density (5.3.2) and thermal
expansion coeficient (5.3.3).
Manufacturer calculates external
pressure capability (5.3.4)
