Figure 1 (continued) – Procedure for declaring manufacturer's data
3.1 Long term regression testing
The manufacturer shall provide at least one full regression curve (as per ASTM D2992 as modified in this
clause and in clause 4.1. The regression curve shall be at 65 °C or higher for GRE and 21 °C or higher for
GRUP or GRVE.
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 is acceptable. The manufacturer's gradient from the full regression curve can be compared to the values in
Table B.1 and a gradient can be selected per the process in Annex B. 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, in a single pipe
size, the size to be determined by the manufacturer.
NOTE 2 For economical and practical reasons, long term regression testing is typically conducted on small diameters.
The recomended 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).

The test fluid shall be potable water.
NOTE 4 For testing completed prior to the publication of this standard, the test fluid may be salt water. In this case, the
salt content must be specified and it must not be greater than 35 g/L. The intention of this requirement is to allow
validation of existing test data completed before the publication of this document, but to require potable water for future
testing. Potable water is a more aggressive test media 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.

o o
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 noted:
o o
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
o
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.
o
c) The default temperature for GRUP is established at 21 C since there are many applications for GRUP
o
near ambient temperature and the amount of qualification testing for pressure by manufacturers at 65 C
o o
is less than that at 21 C to 50 C.
o
d) While GRVE may be suitable for applications at temperatures above 65 C, the amount of qualification
o
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.

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.
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 may
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.
Fortunately, most of these chemicals do not permeate quickly, so practical liners are possible. Other standards, such as
ASTM D3681 or EN 13121-2, may be suitable as a qualification programme to predict the thickness of the liner based on
exposure to various chemicals in a stressed condition.
3.4.3 Partial factor for cyclic loading, A

A is specified in clause 5.1.3 of ISO 14692-3.

3.5 Long term envelope data points

h,LT,2:1,xx a,LT,2:1,xx
σ , σ , σ , σ , σ , and σ ) and the threshold envelope data points
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
(σ , σ , σ , σ , σ , and σ ) by testing in accordance with Annex D. The
h,thr,2:1, a,thr,2:1, h,thr,Rtest, a,thr,Rtest, a,thr,0:-1, h,thr,1:0,
threshold envelope data points do not have a temperature subscript as the threshold is defined, by default, at
o o
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). Refer to
Annex D for calculations.
3.6 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 chosen from the sizes listed in Table 1 of ISO 7370:1983 or should be
agreed between the manufacturer and principal.
3.7 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)

ISO/DIS 14692-2
c) glass content
The manufacturer shall select samples from standard production to determine the baseline values.
NOTE Samples for baseline testing should not be limited to the 1000 hr qualification samples since these samples
may be anywhere within the standard deviation of the population. Samples should be taken from standard production to
ensure that results are being obtained across the entire standard deviation of the population.
3.8 Flexibility factors and SIFs
The manufacturer shall declare flexibility factors for bends per clause 6.4 of Part 3. The manufacturer shall
declare SIFs for bends and tees per clause 6.5 of Part 3.
3.9 Production processes and jointing instructions
The manufacturer shall declare general production processes and jointing instructions sufficient to verify that
the scaling rules in Annex G have been met. Proprietary processes need not be disclosed.
4 Qualification programme
4.1 General
The qualification programme is a one-time process. If the manufacturer has test data from a previous project,
the manufacturer shall have the option to use this data on other projects. However, the principal shall 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 (ref. ISO 14692-1 Annex D). The principal shall also have
the option, via the Enquiry Sheet in ISO 14692-1 Annex D, to specify which tests, if any, shall be conducted by
an independent third party laboratory.
The qualification programme shall be based on a standard design life of 20 years. A shall be used to scale
0
the design envelope to other design lives. A shall not be greater than 1,0.
0
The test fluid for the qualification procedure for pressure and temperature shall be potable water.
NOTE 1 For testing completed prior to the publication of this standard, the test fluid may be salt water. In this case, the
salt content must be specified and it must not be greater than 35 g/L. The intention of this requirement is to allow
validation of existing test data completed before the publication of this document, but to require potable water for future
testing. Potable water is a more aggressive test media 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 involving internal pressure shall be conducted with unrestrained (i.e. "free") ends.
Refer to Table 1 for a summary of the qualification programme. Refer to Figure 2 for a flowchart of the
procedure for product qualification. Refer to Figure 3 for a flowchart of the procedure for determining elastic
properties.
Permanent repair procedures shall be qualified according to this qualification programme.
NOTE 2 Manufacturer's repair procedures that only involve qualified components would 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 it's joint instructions.
