Designation: D8040 − 17Standard Test Method forCorrosion Test for Heat Transfer Fluids in Glassware 1This standard is issued under the f i xed designation D8040; 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 test method covers a simple beaker-type procedurefor evaluating the effects of heat transfer f l uids (HTF) on metalspecimens under controlled laboratory conditions. Fluids testedunder this method are specif i cally designed for heating and airconditioning (HVAC) systems.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 the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use. Specif i c hazardsstatements are given in 10.1.7.2, 10.1.7.3, 10.1.7.4, and A1.1.6.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade (TBT) Committee.2.

Summary of Test Method3.1 In this test method, specimens of metals typical of thosepresent in HVAC systems are totally immersed in aerated HTFsolutions for 336 h at 88 °C (190 °F). The corrosion-inhibitiveproperties of the test solution are evaluated on the basis of theweight changes incurred by the specimens. Each test is run intriplicate, and the average weight change is determined foreach metal.Asingle test may occasionally be completely out ofline (see 11.2).4. Signif i cance and Use4.1 This test method will generally distinguish betweenHTF’s that are def i nitely deleterious from the corrosion stand-point and those that are suitable for further evaluation.However, the results of this test method cannot stand alone asevidence of satisfactory corrosion inhibition. The actual ser-vice value of an HTF formulation can be determined by morecomprehensive evaluation and f i eld tests, agreed betweencustomer and supplier.5. Apparatus5.1 Container, a 1000-mL, tall-form, spoutless beaker, madeof heat-resistant glass, for containing the HTF solution and testspecimens. The beaker shall be tightly closed with a No. 15rubber stopper, having drill holes to accommodate a watercondenser, an aerator tube, and a thermometer as shown in Fig.1. Optionally, an all-glass apparatus may be used. 41 This test method is under the jurisdiction of ASTM Committee D15 on EngineCoolants and Related Fluids and is the direct responsibility of SubcommitteeD15.30 on Industrial Heat Transfer Fluids.Current edition approved May 1, 2017. Published June 2017. DOI: 10.1520/D8040-17.2 For referenced ASTM standards, visit the ASTM website, www.astm.org, orcontact ASTM Customer Service at service@astm.org. For Annual Book of ASTMStandards volume information, refer to the standard’s Document Summary page onthe ASTM website.3 Details available from ASTM International Headquarters. Order Adjunct No.ADJD1384. Original adjunct produced in 1980.4 The sole source of supply of the apparatus known to the committee at this timeis Corning Glass Works. Gas-dispersion tube No. 39533, manufactured by CorningGlass Works, 44-5 Crystal St., Corning, NY, has generally been found satisfactoryfor this purpose. Optionally, a capillary tip bleed tube with 0.28-in. (7-mm) bore and11.2-in. (280-mm) length may be used when consistent early plugging of gasdispersion tubes occurs. The tube, catalog No. 7815-19, may be obtained fromCorning Glass Works, Corning, NY 14830. If you are aware of alternative suppliers,please provide this information to ASTM International Headquarters. Your com-ments will receive careful consideration at a meeting of the responsible technicalcommittee, 1 which you may attend.Copyright © ASTM International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959.
