Designation:D384197(Reapproved 2008)1An American National StandardStandard Specification forGlass-Fiber-Reinforced Polyester Plastic Panels1This standard is issued under the fixed designation D3841;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.This standard has been approved for use by agencies of the Department of Defense.1NOTEEditorial changes were made throughout in April 2008.1.Scope*1.1 This specification covers the classification,materials ofconstruction,workmanship,minimum physical requirements,and methods of testing glass-fiber reinforced polyester plasticpanels intended for use in construction.Panels for specializedor unique applications may require values significantly aboveor below those stated in this specification.Recommendedpractices for certain specific applications are included asAppendix X1.This specification is not intended to restrict orlimit technological changes affecting performance when thosechanges are agreed upon between the purchaser and the seller.1.2 Supplementary information on chemical resistance,re-sistance to heat,and installation practices are provided inAppendix X1.1.3 The classification of these plastic panels into typesbased on relative response to a laboratory test shall not beconsidered a fire hazard classification.1.4 The values stated in inch-pound units are to be regardedas the standard.The values given in parentheses are forinformation only.1.5 The text of this standard references notes and footnoteswhich provide explanatory material.These notes and footnotes(excluding those in Tables and Figures)shall not be consideredas requirements of this standard.1.6 Laboratory flammability tests(Test Methods D635,D1929,D2843,and E84)applicable to this standard should beused to measure and describe the properties of materials,products,or assemblies in response to heat and flame undercontrolled laboratory conditions and should not be used todescribe or appraise the fire hazard or fire risk of materials,products,or assemblies under actual fire conditions.However,results of these tests may be used as elements of a fire riskassessment which takes into account all of the factors whichare pertinent to an assessment of the fire hazard of a particularend use.1.7 The following precautionary caveat pertains only to thetest method portion,Section 8 of this specification.Thisspecification does not purport to address all of the safetyconcerns,if any,associated with its use.It is the responsibilityof the user of this specification to establish appropriate safetyand health practices and determine the applicability of regu-latory limitations prior to use.NOTE1There is no known ISO equivalent to this standard.2.Referenced Documents2.1 ASTM Standards:2D570 Test Method for Water Absorption of PlasticsD618 Practice for Conditioning Plastics for TestingD635 Test Method for Rate of Burning and/or Extent andTime of Burning of Plastics in a Horizontal PositionD638 Test Method for Tensile Properties of PlasticsD696 Test Method for Coefficient of Linear Thermal Expan-sion of Plastics Between 30C and 30C with a VitreousSilica DilatometerD790 Test Methods for Flexural Properties of Unreinforcedand Reinforced Plastics and Electrical Insulating Materi-alsD883 Terminology Relating to PlasticsD1435 Practice for Outdoor Weathering of PlasticsD1494 Test Method for Diffuse Light Transmission Factorof Reinforced Plastics PanelsD1600 Terminology forAbbreviated Terms Relating to Plas-ticsD1929 Test Method for Determining Ignition Temperatureof PlasticsD2843 Test Method for Density of Smoke from the Burningor Decomposition of Plastics1This specification is under the jurisdiction of ASTM Committee D20 onPlastics and is the direct responsibility of Subcommittee D20.24 on Plastic BuildingProducts.Current edition approved March 1,2008.Published April 2008.Originallyapproved in 1980.Last previous edition approved in 2001 as D3841 97(2001).DOI:10.1520/D3841-97R08E01.2For 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 D3892 Practice for Packaging/Packing of PlasticsD4364 Practice for Performing Outdoor Accelerated Weath-ering Tests of Plastics Using Concentrated SunlightD4968 Guide for Annual Review of Test Methods andSpecifications for PlasticsE72 Test Methods of Conducting Strength Tests of Panelsfor Building ConstructionE84 Test Method for Surface Burning Characteristics ofBuilding MaterialsE631 Terminology of Building Construc
