Designation:D384116An 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 U.S.Department of Defense.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 have the potential to require valuessignificantly above or below those stated in this specification.Recommended practices for certain specific applications areincluded as Appendix X1.This specification is not intended torestrict or limit technological changes affecting performancewhen those changes are agreed upon between the purchaserand 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 Fire properties are determined by using laboratoryflammability tests(Test Methods D635,D1929,and E84).1.6.1 This standard is used to measure and describe theresponse of materials,products,or assemblies to heat and flameunder controlled conditions,but does not by itself incorporateall factors required for fire hazard or fire risk assessment of thematerials,products or assemblies under actual fire conditions.1.6.2 Fire testing is inherently hazardous.Adequate safe-guards for personnel and property shall be employed inconducting these tests.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 PlasticsD3892 Practice for Packaging/Packing of PlasticsD4364 Practice for Performing Outdoor Accelerated Weath-ering Tests of Plastics Using Concentrated SunlightE72 Test Methods of Conducting Strength Tests of Panelsfor Building ConstructionE84 Test Method for Surface Burning Characteristics ofBuilding MaterialsE631 Terminology of Building Constructions1This 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 May 1,2016.Published May 2016.Originallyapproved in 1980.Last previous edition approved in 2008 as D3841 97(2008)1.DOI:10.1520/D3841-16.2For 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 E831 Test Method for Linear Thermal Expansion of SolidMaterials by Thermomechanical AnalysisE903 Test Method for Solar Absorptance,Reflectance,andTransmittance of Materials Using Integrating SpheresE972 Test Method for Solar Photometric Transmittance ofSheet Materials
