1、Designation: D 4339 01 (Reapproved 2007)Standard Test Method forDetermination of the Odor of Adhesives1This standard is issued under the fixed designation D 4339; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last rev
2、ision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This test method describes a procedure for e
3、valuatingthe odor of adhesives. It is intended to replace FederalStandard 175A, Method 4051.1.2 This test method provides a means of comparing theodor of an adhesive sample to a reference sample. It is notintended to give an absolute value for the odor of a sample. Itcan be used for wet or dry sampl
4、es.1.3 The values stated in inch-pound units are to be regardedas the standard. The values given in parentheses are forinformation only.NOTE 1Warning: Do not use this test method with adhesives con-taining hazardous components such as solvent residues and unreactedmonomeric materials.1.4 This standa
5、rd 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.

7、 Specific to This Standard:3.2.1 odor, nthat property of a substance which affects thesense of smell.4. Significance and Use4.1 The results from this determination are useful in deter-mining the suitability of adhesives in applications where theodor level associated with the end use is critical.5. A
8、pparatus5.1 Glass Bottles, 1-qt (1-L), wide-mouth, straight sided,with screw caps.NOTE 2It is important that the bottles and caps be kept clean andodor-free. Discard any bottle which cannot be made visibly clean orodor-free. Wash bottles and caps with a suitable cleaning powder, rinsethoroughly with
9、 tap water, then rinse with distilled water, drain, and dryin an oven. Do all cleaning in an odor-free atmosphere.5.2 Oven or Incubator, for aging samples at elevatedtemperatures.5.3 Aluminum Foil.5.4 Balance, capable of measuring to nearest 0.1 g.6. Test Sample and Test Specimen6.1 Select a test sa
10、mple representative of the adhesive beingtested. It may be liquid or solid. Keep in a tightly closedcontainer until used (5.1).6.2 For the test specimen, place 20.0 6 0.1 g of the testsample into the glass bottle (5.1), cover with aluminum foil,place the cap on the bottle and tighten.NOTE 3Always us
11、e new aluminum foil, never reuse it.7. Reference Sample and Reference Specimen7.1 Select a reference sample, that from prior experience orknowledge, or by agreement between supplier and purchaser ofadhesive, has acceptable odor.7.1.1 Store the reference sample in a tightly closed con-tainer, specifi
12、ed in 5.1, in a reasonably odor-free atmosphere.7.1.2 Take care against contamination of the referencesample. If it is suspected that the reference sample has beencontaminated, discard it and obtain a new reference sample.1This test method is under the jurisdiction of ASTM Committee D14 onAdhesives

15、e specimen, transfer 20.0 6 0.1 g of thereference sample into the glass bottle (5.1), cover with alumi-num foil, place the cap on the bottle, and tighten.8. Conditioning8.1 Age the bottles containing the reference and test adhe-sive specimens for at least 24 h at ambient temperature andhumidity prio
16、r to testing.8.2 If the effect of elevated temperature aging on the odor ofthe adhesive is desired, place the capped bottles containing theadhesive specimens in an oven at the desired aging tempera-ture, and condition for 2 h. Allow the test specimens to cool toambient temperature before evaluating
17、odor.NOTE 4Bottles aged at elevated temperatures must be shielded withina suitable metal container to protect against bottle rupturing.NOTE 5Longer conditioning times may be used, if desired.8.2.1 Evaluate test specimens aged at elevated temperatureswithin a 2-h period after test specimens have retu
18、rned toambient temperature.9. Selection of Odor Panel9.1 Use the following criteria for selection of the membersof the odor panel:9.1.1 The panel is to consist of at least three people.9.1.2 Preferably, panel members are to be nonsmokers.9.1.3 Panel members are not allowed to smoke, eat, or drink(ot
19、her than water) for approximately 1 h prior to evaluatingsamples.9.1.4 No person with a cold or nasal congestion, or who hasbeen working with chemicals with strong odors, is allowed tobe a panel member.9.1.5 Panel members are to be free of odors from scentedcosmetics.10. Procedure10.1 Pair each adhe
20、sive test specimen to be tested with areference specimen that has undergone identical conditioning.10.2 Remove the cap and foil and immediately sniff theodor. Keep the bottle closed except for the short periodnecessary to sniff the specimen. (WarningSee Note 1.)10.3 Indicate for each pair of samples
21、 whether the odor ofthe adhesive specimen is less than, equal to, or greater than thereference specimen.10.4 Observe the following conditions when conducting thetests:10.4.1 All panel members are to conduct testing on the sameday and within a period of 4 h. See 8.2 for instructions forhandling speci
22、mens conditioned at elevated temperatures.10.4.2 Each panel member is to perform the odor testing ina room free of odors and evaluate all specimens in the sameroom at the same time. All panel members are to use the sameroom.NOTE 6Odor fatigue can occur if many samples are evaluated at onetime or if
23、many rechecks are required to reach a decision on the samesample. If this occurs, allow at least 5 min for the nose to regain its formersensitivity. Panel members may find that the sense of smell is sharpenedif specimens are rated with the eyes closed.11. Interpretation of Results11.1 Compile the od
24、or testing results from the panel mem-bers. Report the odor level receiving the majority of the votesas the odor level for the test sample.11.2 If no odor level receives a majority, then rate the testsample as having odor equal to the reference sample.12. Report12.1 Include in the report the followi
25、ng:12.1.1 Test sample identification,12.1.2 Reference sample identification,12.1.3 Conditioning procedure for test and reference speci-mens,12.1.4 Odor of test specimen as less than, equal to, orgreater than the odor of the reference specimen, and12.1.5 Date of evaluation.13. Precision and Bias13.1
26、No information is presented about either the precisionor bias of Test Method D 4339 for measuring odor since thetest result is nonquantitative.NOTE 7For a more complete treatment of odor testing by sensoryperception, see Method D 1391.14.
