Designation:D402508a(Reapproved 2013)Standard Practice forReporting Results of Examination and Analysis of DepositsFormed from Water for Subsurface Injection1This standard is issued under the fixed designation D4025;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.1.Scope1.1 This practice covers the manner in which the variousresults of examination and analysis to determine the composi-tion of deposits formed from water for subsurface injection areto be reported.1.2 All analyses shall be made in accordance with the testmethods of ASTM,unless otherwise specified.NOTE1While reporting of inorganic constituents in water-formeddeposits as specified in Test Methods D4412 is sufficient for certainindustries,this practice provides for the reporting of organic and biologi-cal materials as well as inorganic constituents.NOTE2Consistent with practices in industries where subsurfaceinjection of water is practiced,reporting includes specifying of inorganicconstituents as probable molecular combinations of the species for whichanalyses are performed.1.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.4 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 Documents2.1 ASTM Standards:2D887 Practices for Sampling Water-Formed DepositsD932 Test Method for Iron Bacteria in Water and Water-Formed DepositsD933 Practice for Reporting Results of Examination andAnalysis of Water-Formed DepositsD1129 Terminology Relating to WaterD4412 Test Methods for Sulfate-Reducing Bacteria in Waterand Water-Formed DepositsE29 Practice for Using Significant Digits in Test Data toDetermine Conformance with Specifications3.Terminology3.1 DefinitionsFor definitions of terms used in thispractice,reference should be made to Terminology D1129 andPractice D887.4.History of Sample4.1 Information regarding the source and history of thesample shall be included in the report of the analysis.Thisinformation should be that supplied by the individual submit-ting the sample as follows:4.1.1 Name of company supplying the sample,4.1.2 Name of location of plant,facility,and well,4.1.3 Date and time of sampling,4.1.4 Number of sample,4.1.5 Name and other designation of equipment from whichsample was removed,4.1.6 Precise location from which sample was removed,4.1.7 Operating temperature and pressure of water or brineat location of deposit,4.1.8 Type of treatment applied to the water that formed thedeposit,4.1.9 An account of system operating conditions that mayhave contributed to deposition(for example,filter channeling,chemical pump outage,or increased system temperature),4.1.10 Appearance and extent of deposit prior to removal,4.1.11 Exact method that was used in removing the sampleand notes concerning any contamination that might haveoccurred during the process,4.1.12 Specific methods used for preservation of sampleprior to and subsequent to removal,4.1.13 Results of field tests made on the sample or relatedequipment,4.1.14 An analysis of the water from which the deposit wasformed,and4.1.15 Identity of sampler.1This practice is under the jurisdiction of ASTM Committee D19 on Water andis the direct responsibility of Subcommittee D19.05 on Inorganic Constituents inWater.Current edition approved June 1,2013.Published July 2013.Originally approvedin 1981.Last previous edition approved in 2008 as D4025 08a.DOI:10.1520/D4025-08AR13.2For 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 5.Significance and Use5.1 This practice sets down the manner in which dataobtained from other test methods should be reported.This isdone in an effort to standardize the report form used.6.Physical Characteristics6.1 The macroscopic characteristics of the sample,as ascer-tained by the analyst,including any peculiarities that may bepertinent to the results of the examination,shall be included inthe report.NOTE3Characteristics such as the following may be recorded:color,form(scaly,slimy,etc.),texture(oily,smooth,friable,gritty,etc.),magnetic properties(as determined by test with magnet),and apparentstructure(amorphous,crystalline,columnar crystals).NOTE4Any discrepancies between the physical characteristics ob-served by the analyst and those reported by the sa
