Designation:D 3879 91(Reapproved 2004)e1Standard Test Method forSampling Amphibole Asbestos1This standard is issued under the fixed designation D 3879;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(e)indicates an editorial change since the last revision or reapproval.e1NOTEAsbestos warning was moved from 7.1.1 to 1.5 in September 2004.1.Scope1.1 This test method describes the procedure for taking acomposite sample or a master composite sample(at the mine,at the factory,or from a consignment)from a lot of commercialmilled amphibole fibers,conditioning the sample,and reducingit in quantity so as to provide a series of relatively small testspecimens of loose asbestos fiber,each of which may beregarded as representative of the lot.(See Appendix X1 forsampling strategy.)1.2 This test method is suitable for taking test specimens ofamphibole asbestos for the following test methods:C 1119,C 1120,C 1121,C 1122,C 1123,C 1124,C 1125,C 1162,D 1118,D 2589,D 2752,D 2947,D 2985,D 2987,D 3639,D 3752,and D 3880.1.3 For sampling chrysotile asbestos,use Method D 2590.1.4 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.5 WarningBreathing of asbestos dust is hazardous.Asbestos and asbestos products present demonstrated healthrisks for users and for those with whom they come into contact.In addition to other precautions,when working with asbestos-cement products,minimize the dust that results.For informa-tion on the safe use of chrysoltile asbestos,refer to“Safe Useof Chrysotile Asbestos:A Manual on Preventive and ControlMeasures.”21.6 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 and health practices and determine the applica-bility of regulatory limitations prior to use.See 1.5 for aspecific hazard warning.2.Referenced Documents2.1 ASTM Standards:3C 1119 Test Method for Vacuum Drainage of Asbestos-Cement MixesC 1120 Test Method for Wash Test of AsbestosC 1121 Test Method for Turner and Newall(T and N)Wet-Length Classification of AsbestosC 1122 Test Method for Wet Volume of AsbestosC 1123 Test Method for Compressibility and Recovery ofAsbestosC 1124 Test Method for Kerosene Retention of AsbestosC 1125 Test Method for Penetration Index of AsbestosC 1162 Test Method for Loose Density of AsbestosD 1118 Test Method for Magnetic Rating of Asbestos Fiberand ProductsD 2589 Test Method for McNett Wet Classification ofAsbestos FibersD 2590 Test Method of Sampling Chrysotile AsbestosD 2752 Test Methods for Air Permeability of AsbestosFibersD 2946 Terminology Relating to Asbestos and Asbestos-Cement ProductsD 2947 Test Method for ScreenAnalysis ofAsbestos FibersD 2985 Test Method for Color of AsbestosD 2987 Test Method for Moisture Content of AsbestosFiberD 3639 Test Method for Classification of Asbestos Fibersby Quebec Standard TestD 3752 Test Method for Strength Imparted byAsbestos to aCement MatrixD 3880 Test Method for Asbestos Strength Units3.Terminology3.1 Definitions of Terms Specific to This Standard:1This test method is under the jurisdiction of ASTM Committee C17 onFiber-Reinforced Cement Products and is the direct responsibility of SubcommitteeC17.03 on Asbestos-Cement Sheet Products and Accessories.Current edition approved June 1,2004.Published August 2004.Originallyapproved in 1980.Last previous edition approved in 1999 as D 3879 91(1999).2Available from The Asbestos Institute,http:/ 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.1Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.3.1.1 accessible baga bag(in a pile of bags of asbestosfiber)of which at least one side or one end is fully exposed.3.1.2 accessible surfacein a pile of bags of asbestos fiber,a side(of the pile)in which all the bags are accessible bags.3.1.3 amphibole asbestos,nasbestiform amphibole sili-cate minerals including the orthorhombic anthophyllite seriesand the monoclinic cummingtonite grunerite asbestos(amosite)series,the tremolite-actinolite series,and the alkaliamphibole riebeckite asbestos(crocidolite)series amongothers.The amphiboles contain essential(OH)groups in theirstructure,and the Si:O ratio is 4:11.A considerable amount ofelemental substitution can take place in these varieties ofasbestos.The crystal structures are composed of strips orribbons of linked polyhedra that join to form fibrils.Theindividual strips are made up from three components;these aretwo double chains of linked(Si,Al)O4tetrahedra and a stripof linked MgO6,F
