Designation:D34502(Reapproved 2010)Standard Test Method forSampling and Testing Calcium Chloride for Roads andStructural Applications1This standard is issued under the fixed designation D345;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.1.Scope1.1 This test method covers sampling of solid and liquidforms of calcium chloride,and sieve analysis of solid formcalcium chloride.Referee procedures for chemical analysis arecovered in Test Methods E449.1.2 A rapid method of chemical analysis is shown inAppendix X1.This rapid method is not to be used fordetermining chemical compliance of calcium chloride withspecification requirements,such as in Specification D98.1.3 The values stated in SI units are to be regarded as thestandard.1.4 This standard does not purport to address the safetyconcerns,if any,associated with its use.It is the responsibilityof the user of this standard to establish appropriate safety andhealth practices and determine the applicability of regulatorylimitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C136 Test Method for Sieve Analysis of Fine and CoarseAggregatesD98 Specification for Calcium ChlorideD140 Practice for Sampling Bituminous MaterialsE11 Specification for Woven Wire Test Sieve Cloth and TestSievesE449 Test Methods for Analysis of Calcium Chloride3.Significance and Use3.1 This test method describes procedures to be used forsampling calcium chloride,and for determining grading ofsolid forms of calcium chloride for comparison with therequirements of a specification,such as Specification D98.4.Apparatus4.1 Sampling Equipment:4.1.1 Sampling TubeMetal tube,approximately 25 to 40mm(1 to 112in.)diameter,and of appropriate length(500 mm(20 in.),minimum)for sampling solid-form calcium chloride.4.1.2 Sampling BottleSampling devices such as describedin Practice D140 for sampling liquid calcium chloride.4.1.3 Sampling ContainersGlass bottles or semi-rigidplastic containers with covers with airtight seal for protectingthe samples from time of sampling until the samples ae used intesting.The containers for solid-form calcium chloride shallhave wide mouths or openings for solid-form calcium chloride.4.2 Sieves,with the size openings required for the test,shallconform to the requirements of Specification E11.4.3 Balances,having a capacity of at least 250 g,shall bereadable to 0.1 g,and shall be accurate to 0.1 g or 0.1%of thetest load,whichever is greater,at any point within the range ofuse.5.Sampling5.1 Solid-Form Calcium Chloride:5.1.1 Package ShipmentsSelect not less than three con-tainers at random from the shipment.For drums,sample eachof the containers by scraping aside the top layer to a depth ofapproximately 25 mm(1 in.)and taking 0.5 kg(1 lb)samplesby means of a sampling tube or other method that will ensurea sample that is representative of a cross section of thematerials in the container to a depth of at least 150 mm(6 in.).For bags,take 0.5 kg(1 lb)samples by means of a samplingtube penetrating at least 300 mm(1 ft)into the bag.For smallcontainers with capacity not more than 5 kg(10 lb),use theentire contents of the container.5.1.2 Bulk ShipmentsSelect samples from at least threelocations in the shipment.Scrape aside the top layer to a depthof approximately 300 mm(1 ft).Using a sampling tube,obtaina sample extending from the cleared surface to at least 50%ofthe depth of the material in the container,or a depth of1This test method is under the jurisdiction of ASTM Committee D04 on Roadand Paving Materials and is the direct responsibility of Subcommittee D04.31 onCalcium and Sodium Chlorides and Other Deicing Materials.Current edition approved Aug.15,2010.Published November 2010.Originallypublished as D345 32 T.Last previous edition approved in 2002 as D345 02.DOI:10.1520/D0345-02R10.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 approximately 1 m(3 ft),whichever is less.Each sample shallcontain at least 0.5 kg(1 lb)of material.5.1.3 Use caution during the sampling operation to avoidexposing the sample unduly to atmospheric moisture.Imme-diately and thoroughly mix the individual samples to form arepresentative composite sample of material and store in asealed glass or suitable plastic container.5.2 Liquid-Form Calcium Chloride,Bulk Shipments orStorageObtain a sample of at least 500 mL(1 pt)from thebulk shipping container or storage tank or during discharge.Recir
