Designation:C1629/C1629M15Standard Classification forAbuse-Resistant Nondecorated Interior Gypsum PanelProducts and Fiber-Reinforced Cement Panels1This standard is issued under the fixed designation C1629/C1629M;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 standard establishes classifications of abuse resis-tance based on the abrasion resistance and impact resistanceperformance of nondecorated interior gypsum panel productsand fiber-reinforced cement panels(abuse resistant wall pan-els).1.1.1 This standard is a method of classifying gypsum panelproduct performance and is not intended to classify systems forabuse resistance.1.2 The values stated in inch-pound and SI(metric)units areto be regarded separately as standard.Within the text,the SIunits are shown in brackets.The values stated in each systemshall be used independent of the other.Values from the twosystems shall not be combined.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:2C11 Terminology Relating to Gypsum and Related BuildingMaterials and SystemsC473 Test Methods for Physical Testing of Gypsum PanelProductsC840 Specification forApplication and Finishing of GypsumBoardC1154 Terminology for Non-Asbestos Fiber-Reinforced Ce-ment ProductsD4977 Test Method for Granule Adhesion to Mineral Sur-faced Roofing by AbrasionD5420 Test Method for Impact Resistance of Flat,RigidPlastic Specimen by Means of a Striker Impacted by aFalling Weight(Gardner Impact)E695 Test Method of Measuring Relative Resistance ofWall,Floor,and Roof Construction to Impact Loading2.2 ISO Documents:ISO 6707-1 Building and Civil EngineeringVocabularyPart 1:General Terms3.Terminology3.1 Definitions of terms shall be in accordance with Termi-nologies C11 and C1154.3.2 Definitions of Terms Specific to This Standard:3.2.1 failure(hard body impact),ntest result constitutedby the penetration or deformation of the wall cavity by theimpact head establishing a residual deflection of the panelexceeding the nominal thickness of the test panel.3.2.2 structural failure(soft body impact),na test resultconstituted by the penetration or deformation of the wall cavityby the soft body impact bag establishing a residual deflectionof any area on the test panel that exceeds the nominal thicknessof the test panel.3.2.2.1 deformation,nchange of shape or dimension orboth.ISO 6707-13.2.2.2 surface damage,npulverization of the core of thetest panel at the point of impact,which is evidenced bycracking,creasing,or other visible damage short of failure asdefined in 3.2.2.3.2.3 residual deflection,npermanent deformation of abuilding element,component,or structure after removal ofapplied force.3.2.3.1 DiscussionAlso called permanent set or residualdeformation.4.Significance and Use4.1 Each abuse/impact property of abuse resistant wallpanels is divided into three classification levels.The threelevels of classification are:Level I,Level II,and Level III,withLevel I representing the lowest rating for any given property.The test methods specified are utilized to establish the abuse-resistance classification of an abuse resistant wall panel.Each1This classification is under the jurisdiction of ASTM Committee C11 onGypsum and Related Building Materials and Systems and is the direct responsibilityof Subcommittee C11.01 on Specifications and Test Methods for Gypsum Products.Current edition approved June 1,2015.Published July 2015.Originally approvedin 2005.Last previous edition approved in 2014 as C1629/C1629M 14a.DOI:10.1520/C1629_C1629M-15.2For 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 States1 classification level requires a minimum overall specified per-formance.Any classified abuse resistant wall panel can be usedat a classification level which is rated lower than the highestlevel qualified.5.Basis of Classification5.1 Abuse resistant wall panels are classified into one ofthree levels of abuse resistance based on minimum perfor-mance when tested in accordance with test methods thatevaluate surface abrasion,indentation,soft body impact,andhard body impact as specified in 6.1 6.4.5.2 Minimum requirements for each level are as shown inTables 1-
