1、Designation: D 3310 00 (Reapproved 2006)Standard Test Method forDetermining Corrosivity of Adhesive Materials1This standard is issued under the fixed designation D 3310; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of l

2、ast revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) 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

3、 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 thesa

4、fety 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.

5、G15 Terminology Relating to Corrosion and CorrosionTesting3. Terminology3.1 DefinitionsDefinitions of terms in this test methodmay be found in Terminologies D 907 and G15.3.1.1 corrosivity, nthe tendency to cause corrosion.4. Summary of Test Method4.1 The metal of interest is enclosed in a glass con

6、tainerwith 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. Signi

7、ficance 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-fl

8、uorocarbon.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

9、.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.NOTE 1Here metal is

10、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 instruc

11、tions before placing itin the large jar.NOTE 2Hot-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 t

12、hesame 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 Meta

Cleanliness9.1 Clean the jars and covers so that no foreign matter ispresent.9.2

15、 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 scaleo

16、f 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

17、 adhesive so that thecorrosive condition in the embedded area may be reported.11. Report11.1 Report the following information:11.1.1 Identification of the adhesive evaluated and curecycle.11.1.2 Identification of the metal in detail (that is, specificalloy, temper and special treatment such as cold

18、working, etc).11.1.3 Description of the condition of test (that is, whetherexposure was during cure, after cure and with or without waterbeing present).11.1.4 Storage time and temperature.11.1.5 Degree of corrosion on scale of five after convenientintervals. (If corrosion is rapid and severe initial

19、 report may beafter 1 h. Otherwise, observations may be made and recordedafter 1, 3, and 7 days.)11.1.6 Any unusual aspect of corrosion such as pitting,cracking, and adhesive cure inhibition, etc.12. Precision and Bias12.1 Precision and bias statements can not be established,because the test is subj

20、ective. The degree of corrosion presenton the test specimen is determined by visual comparison tocontrols, a judgment evaluation. This is not a practical basis forstatements of this nature.13.
