Designation:D7367/D7367M22Standard Test Method forDetermining Water Holding Capacity of Fiber Mulches forHydraulic Planting1This standard is issued under the fixed designation D7367/D7367M;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.Scope*1.1 This quantitative test method determines the waterholding capacity of fiber mulches,including wood,paper,andagriculturally derived and blended fiber mulches that are usedfor hydraulic seeding and planting.Results from this testingcan be used as a quality assurance and/or quality control datafor manufacturing processes.1.2 There are no known limitations to this test method.1.3 UnitsThe values stated in either inch-pound units orSI units are to be regarded separately as standard.The valuesstated in each system may not be exact equivalents;therefore,each system shall be used independently of the other.Combin-ing values from the two systems may result in nonconformancewith the standard.Reporting of test results in units other thaninch-pound shall not be regarded as nonconformance with thisstandard.The amount of test water is presented in mL and noother unit of measurement is given.1.3.1 The gravitational system of inch-pound units is usedwhen dealing with inch-pound units.In the system,the pound(lbf)represents a unit of force(weight),while the units formass is slugs.The slug unit is not given,unless dynamic(F=ma)calculations are involved.This standard includes thegravitational system of inch-pound units and does not use/present the slug unit of mass.1.3.2 The slug unit of mass is typically not used in com-mercial practice;that is,density,balances,and so on.Therefore,the standard unit for mass in this standard is eitherkilogram(kg)or gram(g),or both.1.4 All observed and calculated values shall conform to theguidelines for significant digits and rounding established inPractice D6026.1.4.1 The procedures used to specify how data are collected/recorded or calculated in the standard are regarded as theindustry standard.In addition,they are representative of thesignificant digits that generally should be retained.The proce-dures used do not consider material variation,purpose forobtaining the data,special purpose studies,or any consider-ations for the users objectives;and it is common practice toincrease or reduce significant digits of reported data to becommensurate with these considerations.It is beyond the scopeof this standard to consider significant digits used in analysismethods for engineering data.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.6 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:2D653 Terminology Relating to Soil,Rock,and ContainedFluidsD3740 Practice for Minimum Requirements for AgenciesEngaged in Testing and/or Inspection of Soil and Rock asUsed in Engineering Design and ConstructionD4753 Guide for Evaluating,Selecting,and Specifying Bal-ances and Standard Masses for Use in Soil,Rock,andConstruction Materials TestingD6026 Practice for Using Significant Digits and Data Re-cords in Geotechnical DataE11 Specification for Woven Wire Test Sieve Cloth and TestSieves3.Terminology3.1 DefinitionsFor definitions of common technical termsused in this standard,refer to Terminology D653.1This test method is under the jurisdiction ofASTM Committee D18 on Soil andRock and is the direct responsibility of Subcommittee D18.25 on Erosion andSediment Control Technology.Current edition approved June 1,2022.Published June 2022.Originallyapproved in 2007.Last previous edition approved in 2019 as D7367 192.DOI:10.1520/D7367_D7367M-22.2For 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.*A Summary of Changes section appears at the end of this standardCopyright 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 Tr
