Designation:C1306/C1306M08(Reapproved 2016)1Standard Test Method forHydrostatic Pressure Resistance of a Liquid-AppliedWaterproofing Membrane1This standard is issued under the fixed designation C1306/C1306M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1NOTEUnits information was editorially corrected in November 2016.1.Scope1.1 This test method describes a laboratory procedure fordetermining the resistance of a waterproofing membrane tohydrostatic pressure.1.2 The committee with jurisdiction over this standard is notaware of any comparable standards published by other orga-nizations.1.3 There are no ISO standards similar or equivalent to thisASTM standard.1.4 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.5 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:2C717 Terminology of Building Seals and SealantsC1375 Guide for Substrates Used in Testing Building Sealsand Sealants3.Terminology3.1 DefinitionsRefer to Terminology C717 for definitionsof technical terms used in this test method.4.Summary of Test Method4.1 This test method is conducted in two stages.In the firststage,the test membrane is subjected to hydrostatic pressurethat is increased steadily over an 8 h period until the specimenfails or the maximum pressure is achieved.In the second partof the test,three more specimens are subjected to hydrostaticpressure that is increased slowly from 50%of the failure valueto failure in 2.5 psi increments every two to three days.5.Significance and Use5.1 This test method is used as a screening tool to determinethe hydrostatic pressure to which a liquid-applied waterproof-ing membrane may be subjected without failing when stretchedover a crack in the substrate.This test method discriminatesbetween a membrane that is very resistant to hydrostaticpressure and one that is not.Because of the variability inherentin this test method,it is not recommended that this test methodbe used to set a numerical standard for hydrostatic pressureresistance.No prediction of durability at lower hydrostaticpressures can be made when using the results of this testmethod.6.Comparison to Other Standards6.1 The committee with jurisdiction over this standard is notaware of any comparable standards published by other orga-nizations.7.Apparatus and Materials7.1 Test Apparatus,made of Schedule 80 PVC pipe piecesand constructed as shown in Fig.1.7.2 Masking Tape.7.3 TFE-Fluorocarbon or Polyethylene Spacers,three,51by 19 by 3 mm 2 by 0.75 by 0.125 in.7.4 Circulating Hot-Air Oven.7.5 Source of Regulated Compressed Air,capable of at least45 psig.7.6 Epoxy Cement,with gap filling capability,or non-sagconstruction mastic.1This test method is under the jurisdiction ofASTM Committee D08 on Roofingand Waterproofing and is the direct responsibility of Subcommittee D08.22 onWaterproofing and Dampproofing Systems.Current edition approved Nov.1,2016.Published November 2016.Originallyapproved in 1995.Last previous edition approved in 2008 as C1306 08.DOI:10.1520/C1306_C1306M-08R16E01.2For 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 7.7 Sealing Gaskets,eight,102 mm 4 in.outside diameterby 57 mm 2.25 in.inside diameter by 6 mm 0.25 in.thickmade of very soft rubber.37.8 Vernier Calipers.8.Preparation of Substrates8.1 Prepare mortar substrates as described in Guide C1375.8.2Cut the blocks into matching pairs each measuringapproximately 100 by 50 by 12 mm 4 by 2 by 0.5 in.8.3 Other substrates may be used,and shall be prepared toprovide a clean,level test surface.Other preparation require-ments shall be as agreed upon between the supplier and thespecifier.9.Conditioning/Mixing9.1 Store all materials to be tested at standard conditions of23 6 2C 73.4 6 3.6F and 50 6 5%relative humidity forat least 24 h before any test specimens are prepared.9.2 Follow the manufacturers instructions for mixing andpreparing membrane materials for testing.9.3 Whenaprimerisrequiredbythemembranemanufacturer,use the primer as instructed
