Designation:D331000(Reapproved 2014)Standard Test Method forDetermining Corrosivity of Adhesive Materials1This standard is issued under the fixed designation D3310;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 is intended to determine whether anadhesive material,cured or uncured,is corrosive to a metal.Itis a general test method intended to screen out those materialsthat give a visible sign of corrosion.1.2 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are provided forinformation purposes only.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.2.Referenced Documents2.1 ASTM Standards:2D907 Terminology of AdhesivesG15 Terminology Relating to Corrosion and Corrosion Test-ing(Withdrawn 2010)33.Terminology3.1 Definitions:3.1.1 Definitions of terms in this test method may be foundin Terminologies D907 and G15.3.1.2 corrosivity,nthe tendency to cause corrosion.4.Summary of Test Method4.1 The metal of interest is enclosed in a glass containerwith the adhesive material.The containers are stored intemperature-controlled ovens at various temperatures with andwithout water present.4.2 Controls,glass jars containing samples(strips)of thesame metal with and without water but no adhesive stored inthe same oven for comparison.5.Significance and Use5.1 This test method is a subjective test in that determina-tions of degree of corrosivity is based upon a visual inspectionfor a green discoloration or other evidence of corrosion.6.Apparatus6.1 Glass Jars,wide-mouth,with screw cap(8-oz size).Thecap liner shall be TFE-or FEP-fluorocarbon.6.2 Forced Draft Circulating Air Oven,capable of main-taining 71 6 2C(160 6 4F);93 6 2C(200 6 4F);12162C(250 6 4F).Other temperatures can be used withagreement of interested parties.6.3 Open Glass Jars or Cups,1-oz size.6.4 Metal or metals being checked for corrosion.7.Procedure7.1 Place 5 to 10 g of the adhesive in a small glass jar withthe metal being evaluated partly embedded in the adhesive.Place this small uncovered jar in a large jar.Screw the cap ofthe large jar tightly in place.Then place the jar in the oven ata temperature as specified in 6.2.NOTE1Here metal is exposed during cure rather than after cure.7.2 Same as 7.1,except place a small jar half filled withdistilled water in a large jar with the jar containing adhesiveand metal.However,do not use water above 71C.7.3 Same as 7.1 and 7.2,except cure the adhesive inaccordance with manufacturers instructions before placing itin the large jar.NOTE2Hot-melt or air-dried materials are considered to be in thecured state.8.Control8.1 Place a metal specimen similar to the specimen beingevaluated in a screw cap jar with no adhesive.Tighten thescrew cap in place,and place the jar in the same oven at thesame time as the specimen being evaluated.Store another largejar with a control metal specimen and including a small jar withwater in it in the oven in a similar manner.1This test method is under the jurisdiction of ASTM Committee D14 onAdhesives and is the direct responsibility of D14.80 on Metal Bonding Adhesives.Current edition approved March 1,2014.Published March 2014.Originallyapproved in 1974.Last previous edition approved in 2006 as D3310 00(2006).DOI:10.1520/D3310-00R14.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 9.Cleanliness9.1 Clean the jars and covers so that no foreign matter ispresent.9.2 Abrade the metal strips that are exposed with 600-gritmesh emery paper to achieve a shiny surface.9.3 Expose the metals with corrosion preventive treatmentsas treated.10.Observations10.1 Periodically,make observations of the control andexposed specimens.Note the following information on a scaleof five as follows:10.1.1(1)Exposed sample less tarnished than control,10.1.2(2)Exposed sample same as control,10.1.3(3)Exposed sample slightly worse than control,10.1.4(4)Exposed sample significantly worse than control,10.1.5(5)Exposed sample badly corroded,10.1.6 Where possible remove the adhesive so that thecorrosive condition in the embedded area may be reported.11.Report11.1 Report the following information:11.1.1 Identification of
