Designation:E 1058 02Standard Practice for theToxic Contamination of the Environment in the OperatorEnclosure of Self-Propelled Agriculture Vehicles1This standard is issued under the fixed designation E 1058;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.1.Scope1.1 This practice may be used to determine the level ofspecific harmful airborne contaminants within a vehicle opera-tor enclosure under standardized test conditions.The airexchange rate,air pressure relative to ambient conditions,airtemperature,and relative humidity maintained within theenclosure during the test are also determined.Operator-introduced contaminants are not addressed by this practice.1.2 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 Documents2.1SAE Standards:SAEAir Cleaner Test Code(for Fine Dust)2SAE J1012 Recommended Practice Agricultural EquipmentEnclosure Pressurization System Test Procedure22.2NIOSH Standards:NIOSH 2549 Method for Xylene(Aromatic Hydrocar-bons)3NIOSH 2539 Method for Formaldehyde(Aldehydes)3NIOSH S340 Method for Carbon Monoxide3NIOSHMethod for Malathion(Organic Phosphates)3NIOSHManual of Analytical Methods32.3OSHA Standard:OSHA Instruction CPL 2-2.20,Standard Methods for Sam-pling Air Contaminants4SKC Guide to NIOSH/OSHA Air Sampling Standards53.Terminology3.1 Definitions:3.1.1 aerosols,nsmall droplets of a liquid or particles ofsolid matter suspended in air,for example,a mist,fog,orsmoke.3.1.2 air exchange rate,nthe rate at which the air in aspecific space is removed or replaced,or both.3.1.3 breathing zone,nthe zone surrounding and imme-diately in front of operators face.Assumed to be directlyabove front edge of operators seat and 1.2 m above floor ofenclosure.3.1.4 closed operator enclosure,na structure for enclos-ing or enveloping the operator that is sufficiently air-tight topermit modification of the environment within.3.1.5 contaminant,nan undesirable component in anymaterial or system.3.1.6 differential air pressure,ndifference in the pressureexerted by air at a specific location relative to another selectedlocation.3.1.7 dynamic test,na test conducted while the testsubject is undergoing specified motion.3.1.8 forced air ventilation,nair ventilation which iscreated or aided by a forced movement of air as by a fan orblower.3.1.9 gaseous,adjexisting in the state of a molecular gas(0.001 m particle size);containing no liquid droplets orsolid particles.3.1.10 mists,ncloud-like aggregation of liquid dropletshaving a diameter of 20 m which are temporarily suspendedin air.3.1.11 operator-introduced contaminant,nsubstancewhich is introduced by or as a result of actions of the operator(that is,as carried on operators hands or clothing).3.1.12 primary filter(also particulate filter or fresh-airfilter),na device used for filtering suspended mists andparticulate matter out of intake air.3.1.13 rated air flow,nrate of flow of air in or through asystem specified for designed performance.3.1.14 recirculating filter,nfilter used for filtering the airwhich is recirculated within the operator enclosure(see sec-ondary filter).1These test methods are under the jurisdiction of ASTM Committee E35 onPesticides and are the direct responsibility of Subcommittee E35.26 on Safety toMan.Current edition approved April 10,2002.Published June 2002.Originallypublished as E 105885.Last previous edition E105885(1997).2Available from Society of Automotive Engineers,400 Commonwealth Dr.,Warrendale,PA 15096.3Available from National Institute of Occupational Safety and Health,4676Columbia Parkway,Cincinnati,OH 45226.4Available from Occupational Safety and Health Administration,219 S.Dear-born,Chicago,IL.5Available from SKC,Inc.,863 Valley View Rd.,Eighty Four,PA 15330-9614.1Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.3.1.15 secondary filter,nfilter located in a system whereair in the enclosure is refiltered after passing through theprimary filter(usually for recirculated air)(see recirculatingfilter).3.1.16 self-propelled agricultural vehicle,nan agricul-tural vehicle that has the capability of providing its own motivepower.3.1.17 seat index point(SIP),nreference point relative tothe operators seat as determined by a SIPmeasurement device.3.1.18 static test,na test performed while the test subjectis stationary,in a fixed position.3.1.19 technical material,nthe chemically active ingre-dient of a chemical solution or formulation.3.1.20 test media,nthe materials being used to test theperformance of a
