Designation:D5635/D5635M18Standard Test Method forDynamic Puncture Resistance of Roofing MembraneSpecimens1This standard is issued under the fixed designation D5635/D5635M;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.1.Scope1.1 This test method covers the evaluation of the dynamicpuncture energy that roofing membrane specimens canwithstand,without allowing the passage of water,when sub-jected to impact from a rigid object having a sharp edge.1.2 This laboratory test can be conducted at any desiredtemperature using membrane specimens manufactured in afactory or prepared in a laboratory.1.3 Roof membrane specimens to which the test method isapplicable include bituminous built-up,polymer-modifiedbitumens,vulcanized rubbers,non-vulcanized polymeric,andthermoplastic materials.1.3.1 The applicability of this test method to these mem-brane specimens includes their use in vegetative roof systems.1.4 This test method is not applicable to aggregate-surfacedmembrane specimens;however,it is applicable to specimenshaving factory-applied granules.1.5 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.1.6 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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2C578 Specification for Rigid,Cellular Polystyrene ThermalInsulationD1079 Terminology Relating to Roofing and Waterproofing3.Terminology3.1 Definitions:3.1.1 For definitions of terms used in this test method,referto Terminology D1079.4.Summary of Test Method4.1 The roofing membrane test specimen,set on a thermalinsulation substrate,is subjected to a predetermined dynamicimpact energy created by a rigid falling puncture head.Thehead falls through a quarter-circle trajectory from a verticalposition to horizontal position under gravitational acceleration.4.2 The predetermined dynamic puncture energy is selectedas follows:4.2.1 In accordance with a performance requirement givenin a standard specification in which this test method is cited,or4.2.2 Through agreement between the party requesting thetest and the testing laboratory.4.3 Puncture of the test specimen is assessed by visualexamination and,if necessary,verified by conducting a water-tightness test.5.Significance and Use5.1 An important factor affecting the performance of mem-brane roofing systems is their ability to resist dynamic punctureimpacts.This test method provides a means to assess dynamicpuncture resistance.5.2 This test method can be used to compare the dynamicpuncture resistance of a single type of membrane as a functionof a variety of insulation substrates or,conversely,to compare1This test method is under the jurisdiction ofASTM Committee D08 on Roofingand Waterproofing and is the direct responsibility of Subcommittee D08.20 onRoofing Membrane Systems.Current edition approved July 1,2018.Published July 2018.Originally approvedin 1994.Last previous edition approved in 2011 as D5635/D5635M 11.DOI:10.1520/D5635_D5635M-18.2For 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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 the resistance of a number of membrane specimens set on asingle type of insulation.5.3 The effect of temperature on puncture resistance can bestudied by conducting the test under controlled conditionsusing such equipment as an environmental chamber,oven,orfreezer.5.4 The test method can be useful in developing perfor-mance criteria for membrane roofing systems.5.5
