Designation:F299413Standard Practice forUtilization of Mobile,Automated Cured-In-Place Pipe(CIPP)Impregnation Systems1This standard is issued under the fixed designation F2994;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice describes the procedures for the impreg-nation of 4 to 48 in(100 to 1200 mm)diameter cured-in-placepipe utilizing mobile,automated systems.Temporary impreg-nation facilities set up at the jobsite(“over-the-hole”wet outs)are not covered under this standard.Once resin saturation iscomplete,the wet out liner is then used to rehabilitate existinggravity flow or pressure pipelines,process piping,electricalconduits or ventilation systems.1.2 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D1600 Terminology forAbbreviated Terms Relating to Plas-ticsD5813 Specification for Cured-In-Place ThermosettingResin Sewer Piping SystemsF412 Terminology Relating to Plastic Piping SystemsF1216 Practice for Rehabilitation of Existing Pipelines andConduits by the Inversion and Curing of a Resin-Impregnated Tube3.Terminology3.1 DefinitionsDefinitions are in accordance with Termi-nology F412 and abbreviations are in accordance with Termi-nology D1600,unless otherwise specified.3.2 Definitions of Terms Specific to This Standard:3.2.1 certificate of analysis(COA),nDocumented evi-dence of the quality control testing performed on the resin andcatalyst formulations.As a minimum,the COA shall includethe product name;batch number;date of manufacture;name,address and phone number of manufacturer;test methods;testlimits and actual results.3.2.2 CIPP automation,nThe use of PLCs and HMIs tocontrol the operation of a mobile impregnation unit.As aminimum,the following functions shall be controlled andmonitored by the CIPP automation process:Operating speedand pressure of resin and catalyst pumps;resin and catalysttemperature,mixing ratio,tank levels,utilization,recirculationand dispense;vacuum pump operation;calibration roller speed,direction and gap setting.Data from all installations shall beelectronically stored on an internal memory device integratedinto the HMI and shall be downloadable to an external storagedevice for project quality assurance recordkeeping.The datastored shall at a minimum include:project name,identificationnumber and location;date and time of processing wet out;CIPP liner diameter,thickness and length;and resin andcatalyst temperatures and volumes utilized.Additional datarecorded may include the calibration roller distance,gapsetting and roller speed.3.2.3 cured-in-place pipe(CIPP),na hollow cylindercontaining a nonwoven or a woven material,or a combinationof nonwoven and woven material surrounded by a curedthermosetting resin.Plastic coatings may be included.Thispipe is formed within an existing pipe.Therefore,it takes theshape of and fits tightly to the existing pipe.3.2.4 electric calibration roller,nElectrically driven orvariable speed hydraulic drive device used to assist with theimpregnation process.Resin saturated liners shall pass throughthe rollers at a set speed and gap setting.The gap setting shallbe adjustable and measurable via a mechanical scale or theelectronic display of the HMI.The linear rate of the CIPP linerprocessed through the roller shall be adjustable via a variablespeed drive or the electronic display of the HMI.3.2.5 impregnation module,nfully contained,insulatedsystem used in the production of CIPP on a mobile impregna-tion unit.3.2.5.1 DiscussionThe module shall operate through CIPP1This practice is under the jurisdiction of ASTM Committee F17 on PlasticPiping Systems and is the direct responsibility of Subcommittee F17.67 onTrenchless Plastic Pipeline Technology.Current edition approved Aug.1,2013.Published September 2013.DOI:10.1520/F2994-132For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 automation and as a minimum shall include the followingcomponents:precision pumps and metering devices,bulk resinand catalyst storage tanks with temperat
