Designation:D 1466 86(Reapproved 1995)e1Standard Test Method forSampling Liquid Oils and Fatty Acids Commonly Used inPaints,Varnishes,and Related Materials1This standard is issued under the fixed designation D 1466;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.e1NOTEUnit of measurement statement and Keywords were added editorially in May 1995.1.Scope1.1 This test method covers procedures for obtaining repre-sentative samples of oils,fatty acids,and polymerized fattyacids that are commonly used in paints,varnishes,and relatedmaterials,and that are in a liquid state when sampled.1.2 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of whoever uses this standard to consult andestablish appropriate safety and health practices and deter-mine the applicability of regulatory limitations prior to use.2.Summary of Test Method2.1 Samples of drying oils,fatty acids,and polymerizedfatty acids are subjected to various test methods for determin-ing physical and chemical characteristics.It is necessary toobtain a sample or a composite of several samples in suchmanner and from such locations in the container,that thesample or composite will be truly representative of the product.The precautions required to assure such a representativesample are numerous,depending on the type of product,thecontainer,the cleanliness of the sample container,and thesampling procedure that is to be used.3.Significance and Use3.1 Because precipitated saturated acids or oils containing ahigh proportion of saturated acids,foots,or other insolublematter may not be homogeneous,the sampling procedure mustbe designed so that the sample obtained is representative of theoverall composition of the material.Different sampling proce-dures are presented such that a representative sample may beobtained from material stored in different types of containers.4.Apparatus4.1 Oil Thief:4.1.1 Liquid Oils and Fatty AcidsAglass tube,9.5 to 12.7mm(39to12in.)in internal diameter and approximately 1 m(40 in.)in length.One end shall be constricted by a short taperto approximately 6 mm(14in.),and the other end shall beconstricted sufficiently so that it can be used as a finger valve.This thief is used for sampling casks,drums,etc.4.1.2 Polymerized Fatty AcidsA glass tube,20 to 25 mm(34to 1 in.)in internal diameter,and approximately 1 m(40in.)in length.One end shall be constricted so it can be used asa finger valve.This thief shall be used for sampling casks,drums,etc.4.2 Zone Sampler,305-mm(12-in.)oil thief,2consisting ofa graduated glass tube with either aluminum or cadmium-plated brass fittings.4.3 Compositing Pail,noncorrosive compositing pail,madeof stainless steel,aluminum,enamelware,polyethylene,orcomparable material.4.4 Graduated Cylinders:4.5 Sample Containers,clear glass or brown glass bottles,orcans(for other than fatty acids and polymerized fatty acids).The clear glass bottles are advantageous because they may beexamined visually for cleanliness,sediment,etc.The brownglass bottles afford some protection from light.Only cans thatdo not have any solder flux on the interior are permissible forstoring oils.Cans shall not be used for fatty acids or polymer-ized fatty acids.4.5.1 The closure for the glass bottles may be good qualitycorks,with or without tin or aluminum foil.Screw caps may beused for both bottles and cans.4.5.2 All sample containers shall be clean and free of water,lint,dirt,washing compounds,solvents,flux or acids,rust,oil,etc.1This test method is under the jurisdiction of ASTM Committee D-1 on Paintand Related Coatings,Materials,and Applications and is the direct responsibility ofD01.32 on Drying Oils.Current edition approved March 27,1986.Published May 1986.Originallypublished as D 1466 57.Last previous edition D 1466 67(1984)e1.2Samples manufactured by the W.H.Curtin Co.,Houston,TX,has been foundsuitable for this purpose.1Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.NOTICE:This standard has either been superceded and replaced by a new version or discontinued.Contact ASTM International(www.astm.org)for the latest information.5.Samples5.1 The size of the sample should be kept to a minimum.Inmost instances,0.9 L(1 qt)of material should suffice.However,in many tests,a minimum of 11 L(3 gal)isrequired3.8 L(1 gal)for the purchaser,3.8 L(1 gal)for theseller,and 3.8 L(1 gal)in reserve for a possible arbitrationumpire test.If refining or bleaching tests are required,theminimum quantity is approximately 3.8 L(1 gal).5.2 The oil shall be completely liquid for
