Such collars can be an integral part of acomplete lining of a lateral pipe.

At bends and atirregularities in the host pipe, including local reductions of internal perimeter, folding will generally occur.7.3 Material characteristicsResin cure shall be demonstrated by conformity to 7.5.7.4 Geometric characteristicsNOTEWhen assessing minimum free bore attainable after CIPP installation at bends, changes of cross section or stepped joints in theexisting pipe, the likelihood of local folding should be taken into account (see 7.2).7.4.1 CIPP wall structureThe thicknesses and relative positions of each component layer of the CIPP wall, including tolerances, shall bespecified as declared values. The maximum proportional volume of any entrained air shall likewise be specified.The wall structure shall be verified by visual examination of the edge of a cut section of pipe, with magnification asnecessary, and use of a scale or caliper capable of measuring to within 0,1 mm.NOTEFor the purposes of verifying that any entrained air does not exceed the declared maximum proportional volume, microscopicexamination of a thin section can be necessary.7.4.2 Wall thicknessWhen measured in accordance with prEN ISO 3126 at a temperature of (23 ± 2) °C, the wall thickness of theinstalled pipe shall conform to Table 4.NOTEThe cut edge of the CIPP at manholes and lateral openings might possibly have not a thickness representative of the main body ofthe pipe.SIST EN 13566-4:2003

If however any one of the test pieces subject to strain of 0,9efb,mean fails within 1000 hours, the fullprocedure of EN 1120 shall be followed.If a test piece fails due to the imposition of ring deflection alone, before the test fluid is applied, this shall not beconsidered a strain corrosion failure.NOTE 1Where the carrier material/reinforcement consists entirely of fibres of PET, testing experience indicates that no strain corrosionfailure occurs.NOTE 2Where tests are carried out at high values of flexural strain, it is recommended that samples of pipe having the lowest availablevalue of diameter/thickness ratio are used in order to limit the imposed ring deflection, if possible to less than 10 %.Table 6 — Additional characteristicsTest parameterCharacteristicRequirementParameterValueTestmethodResistance tochemical attack in adeflected conditionMinimum extrapolatedfailure strain at 50 years:³ 0,45 %Composition of test liquidNumber of test piecesTest piece length for

Wherever possible such supportedsamples shall be formed at an intermediate manhole in preference to one or other end of the overall installation.For the purposes of three-point flexural testing to EN ISO 178 in accordance with Table 5 and annex C, theorientation of samples shall be as follows:a)
For CIPP products in which the mean hoop and longitudinal flexural properties can be shown by tests on flatplates to differ by no more than ± 10 %, either longitudinal or hoop samples may be used. The sampleorientation chosen for type testing shall however become the sample orientation requirement for all furtherflexural testing.b)
For CIPP products of anisotropic wall construction, hoop samples only shall be used.In all cases test pieces shall be placed in the testing machine such that the inside surface of the CIPP is in contactwith the supports and therefore subject to tension.SIST EN 13566-4:2003

Finishing equipment: manual or robotic cutters and/or grinders for trimming ends and reopening lateralconnections.8.4 Installation8.4.1 Environmental precautionsThe installation manual shall describe any measures necessary to prevent liquid resin from contaminating theenvironment and to reduce the accumulation of volatile materials in the atmosphere. Where hot processing fluidsare used they shall not be disposed of into the sewer network at temperatures and/or release rates which couldcause damage.NOTEAny local regulations specifying maximum fluid release temperatures should be taken into account.Any lubricant used to reduce friction during installation shall be declared. The installation manual shall describe anyprecautions necessary to prevent possible adverse effects of such lubricant on the CIPP or the environment.SIST EN 13566-4:2003

The temperature at the interface of the lining tube withthe existing pipeline shall be continuously monitored during the curing process by means of sensors located aroundthe invert of the pipe at the downstream end and at other appropriate locations.Where UV systems are used for curing, the light source shall be fitted with means for continuous monitoring of thespeed of advance inside the pipe, radiation intensity and/or electric power. Where electric heating systems areused for curing, the power delivered and temperature at the interface of the lining tube with the existing pipelinereally should likewise be monitored.All monitored process parameters shall be recorded at intervals of sufficient frequency to capture possible events ofshort duration, such as for example pressure surges or peak exotherm temperatures, which could have an impacton performance of the finished product.8.4.3 Simulated installationsSince the processing of CIPP, irrespective of curing system, is sensitive to heat loss to the existing pipeline andsurround, it is necessary to control the thermal environment of simulated installations used to producerepresentative samples for type testing.Unless otherwise prescribed, simulated installations shall be executed in clay or concrete pipe, which is completelysurrounded by at least 300 mm of wet sand, at an initial temperature of not greater than 15 °C.
