Hazards5.1 Many paints, inks, and related materials contain sol-vents, diluents, and residual monomers that may be hazardousor toxic. For hazard information and guid
16、ance, see the suppli-ers Material Safety Data Sheet. Take special precautions whiledetermining the odor of these products. The tests should bemade only as frequently as is necessary for control and theevaluations should be conducted in a manner that provides theleast possible amount of exposure.5.2

Defi
18、ning the Approach6.1 A major consideration for the accomplishment of thetask being undertaken by the user of this guide is how tooperate with untrained people such as paint users, plantworkers, and community residents. The following resourcesare suggested as initial references for review (see also T
19、estMethods E 769 and Practice E 1207):(1) STP 682 (2)2Chapter 1, Background and Chapter 3,General Evaluation Factors,(2) STP 433 (3) Part I Test Method D 4339 is used todetermine the odor of a formulated product (adhesives).7.1.1 Annex A1 of Test Method D 1292 provides a sug-gested system for classi
20、fying odors.7.1.2 A general reference for odor character profiles is givenin DS 61 (6).8. Determining Odor Perception Threshold8.1 The first step is to determine at what concentration in theatmosphere a products odor is perceptible or at what concen-tration a specific odor is detectable over the pro
21、ducts baseodor. Because perception threshold can vary with the indi-vidual, a sufficiently large number of observers is necessary.(See STP 434 (2) Chapter I, Section B Test Subjects, 1bNumber of Panel Members.)8.2 Practice E 679 is used to determine the threshold whilePractice E 544 is used to calib
22、rate the threshold versus1-butanol to define the concentration reference.8.3 By defining the odor threshold, the investigator is able toconfirm that a difference in odor exists when comparing oneproduct to another product as used as a control. The presenceof a different odor is likely to result in a
23、 significantly lowerperception threshold. Practice E 1432 is used to define andcalculate individual and group sensory thresholds9. Isolation and Identification of the Chemical Nature ofthe Odor9.1 IsolationGas Chromatography (GC) and Mass Spec-trometry techniques such as those contained in Practices
24、D 3686, D 3687 and Test Method D 2650 can be used toseparate and identify the volatile fractions of the product, someof which are prime contributors to the products odor.9.1.1 Construction requirements for tests chambers arespecified in STP 433 (3) part II,“ Concentration of Odor Vaporsin Test Chamb
25、ers” and in Practice E 1593, Appendix X1.3.9.1.2 A sample can also be captured by trapping the odorusing carbon adsorption of a gas stream above the vapor spaceof a container of the product.9.2 IdentificationWhile the above methods are capable ofseparating and identifying the volatile components, th
26、ey do notestablish which compounds contribute to the odor. Eachseparated component needs to be evaluated by a trainedsensory panel using odor profiling methods such as thoseoutlined in MNL 13 (7) to determine what fraction or fractionscontribute to the odor. The component, or components, sus-pected
27、of causing differences in odor can be compared toreferenced materials in DS 48A (1). Preparative GC may beneeded to provide an identified fraction of sufficient size forfurther fractionation, identification, and odor profiling.10. Confirming the Results10.1 The product odor must be confirmed by usin
28、g theconclusions of the isolation and identification effort to recon-stitute the odor using the identified components and concen-tration. This reconstituted odor concentrate is then evaluatedby a trained sensory panel using the above methods, to confirmits similarity to the product under investigati
29、on.11. Follow Up Action11.1 Upon confirmation by Section 10, efforts should bemade to reduce or eliminate the main odor contributors fromuse, open storage, or open handling. If 10.1 does not producea positive confirmation, then the investigator must look forsurfaces, objects, etc. that could absorb
30、or chemically alter theobjectionable components in the handling, transport, andstorage phase of the investigation.12.
