3.1.1

abrasion layer

inner layer of composite of declared thickness provided as a sacrificial layer for anticipated abrasion of the CIPP product (3.1.3) in service

3.1.2

carrier material

porous component of the liner, which carries the liquid resin system (3.1.16) during insertion into the pipe being renovated and forms part of the installed lining system once the resin has been cured

3.1.3

CIPP product

cured-in-place pipe product

cured-in-place pipe of a particular design, produced from a liner of specified materials, with a wall structure which is uniquely defined for each diameter/wall thickness combination, and which is impregnated with a specific resin system (3.1.16) and installed by a specific process

3.1.4

CIPP unit

specific cured-in-place pipe produced from a continuous liner, which has been impregnated in one process and installed as a single length

3.1.5

close fit

situation of the outside of the installed liner relative to the inside of the existing pipeline, which can either be an interference fit or include a small annular gap resulting from shrinkage and tolerances only

3.1.6

composite

combination of cured resin system (3.1.16) , carrier material (3.1.2) and/or reinforcement (3.1.15) , excluding any internal or external membranes

3.1.7

curing

process of resin polymerization, which may be initiated or accelerated by the use of heat or exposure to light

3.1.8

design thickness

required wall thickness of the composite (3.1.6) , excluding any abrasion layer (3.1.1) , as determined by structural design

3.1.9

first break

elastic limit or first major discontinuity of the stress-strain curve associated with local failure of the resin matrix or reinforcing fibres

3.1.10

lateral connection collar

fitting for reconnecting a lined main pipe to an existing or renovated lateral pipe

3.1.11

lining tube

flexible tube, consisting of carrier material (3.1.2) , resin system (3.1.16) and any membranes and/or reinforcement (3.1.15) , as combined prior to insertion in the pipe to be lined

3.1.12

nominal CIPP wall thickness

one of a range of discrete lining tube wall thicknesses dictated by the sum of the thicknesses of the individual layers of materials used for tube construction at the “M” stage

3.1.13

permanent membrane

internal or external membrane designed to retain its integrity through the processes of lining tube insertion and resin system (3.1.16) cure, and to provide functions for the operational life of the CIPP liner

3.1.14

preliner

permanent or semi-permanent external membrane which is installed separately before the insertion of the resin-impregnated lining tube (3.1.11)

3.1.15

reinforcement

fibres incorporated in the liner which enhance the dimensional stability of the liner and/or the structural properties of the cured composite (3.1.6)

Note 1 to entry: The reinforcement can be incorporated in the carrier material (3.1.2) , constitute the carrier material, or can be a separate layer.

3.1.16

resin system

thermosetting resin including the curing (3.1.7) agent(s) and any fillers or other additives in specified proportions

3.1.17

semi-permanent membrane

internal or external membrane designed to retain its integrity through the processes of lining tube (3.1.11) insertion and resin system (3.1.16) cure, but not relied on to retain its integrity at the “I” stage

3.1.18

service temperature

maximum sustained temperature at which a system is expected to operate

Note 1 to entry: Service temperature is expressed in degrees Celsius (°C).

3.1.19

temporary membrane

membrane forming the internal or external surface of the pipe at the “M” stage, with functions at the “M” stage only

Note 1 to entry: It is removed during or after the installation.

3.1.20

total thickness

thickness of CIPP at the"I" stage comprising the composite (3.1.6) and any semi-permanent (3.1.17) and permanent membranes (3.1.13)

3.1.21

type testing

testing performed to prove that the material, product, joint or assembly is capable of conforming to the requirements given in the relevant standard

3.2.1

inversion

process of turning a flexible tube or hose inside out by the use of fluid (water or air) pressure

3.2.2

inverted-in-place insertion

method whereby the impregnated lining tube is introduced by inversion (3.2.1) to achieve simultaneous insertion and inflation

3.2.3

winched-in-place insertion

method whereby the flat impregnated lining tube is first pulled into the pipe to be lined and then inflated to bring it up to size

Note 1 to entry: With some techniques, inflation is achieved by inversion (3.2.1) through the pulled-in lining tube (3.1.11) of a separate impregnated tube or dry hose, which is either withdrawn after resin cure or left in place as a permanent internal membrane.
