3、c Interest Group for this Test Method TAPPI CAUTION: This Test Method may include safety precautions which are believed to be appropriate at the time of publication of the method. The intent of these is to alert the user of the method to safety issues related to such use. The user is responsible for

4、 determining that the safety precautions are complete and are appropriate to their use of the method, and for ensuring that suitable safety practices have not changed since publication of the method. This method may require the use, disposal, or both, of chemicals which may present serious health ha

5、zards to humans. Procedures for the handling of such substances are set forth on Material Safety Data Sheets which must be developed by all manufacturers and importers of potentially hazardous chemicals and maintained by all distributors of potentially hazardous chemicals. Prior to the use of this m

6、ethod, the user must determine whether any of the chemicals to be used or disposed of are potentially hazardous and, if so, must follow strictly the procedures specified by both the manufacturer, as well as local, state, and federal authorities for safe use and disposal of these chemicals. Test cond

7、itions for fiber glass mat test methods 1. ScopeThis practice defines the preconditioning and test conditions for testing fiber glass mats. 2. Significance Mat characteristics are sensitive to changes in ambient conditions; therefore, preconditioning and test conditions are defined to facilitate com

8、parison of results between different laboratories. 3. General preconditioning and test conditions Under normal conditions, specimens may be preconditioned and tested at ambient laboratory conditions within the temperature range of 65 to 80F (18 to 27C) and a relative humidity range of 30 to 75%, exc

9、ept as specifically noted in the individual test method. Test specimens should be preconditioned for four hours minimum at the ambient conditions prior to testing. 4. Referee test conditions For referee testing, the general test conditions should be as noted in the individual test method or, 77 2F (

10、25 1C) and 50 3% relative humidity. Test specimens should be preconditioned for four hours minimum prior to testing. 5. Alternate conditions Other test conditions may be employed if agreed upon by both buyer and seller. 6. Report Report that the preconditioning and test conditions specified in this

11、practice were employed in the generation of the test results, or, if different conditions were employed, report the conditions and the reason for the deviation.
