3、ndard Specific 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 re

4、sponsible for 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 seri

5、ous health hazards 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

7、ls. Sample location for fiber glass mat sheets 1. Scope This practice covers the location from which samples are taken from a sheet of fiber glass mat used as a sample test unit for physical property determination. 2. Summary of method This practice details the location of all samples in relation to

8、 the sheet of mat and to each other. 3. Significance This arrangement of sample locations is distributed in a manner designed to represent cross-web and down-web variations in the area covered by the sample of the fiber glass mat for each physical property to be tested. 4. Procedure 4.1 Remove all d

9、amaged layers of mat from the outside of the roll to be sampled. Once completed, obtain samples from the full width of the roll and of sufficient length (or number) to enable all samples to be cut from adjacent lengths (convolutions) of the roll. 4.2 Cut test specimens from the sample unit based on

10、an established pattern using 15 to 18 in. (38.1 to 45.7 cm) lanes which allow full testing across each roll. 5. Sample cutting template 5.1 A metal sample cutting template or a sample cutting die used with a punch press may be prepared to facilitate sample cutting from any specific web. Stainless st

11、eel sheet (10 gauge) has been found suitable for templates and the dimensions of openings should be cut to within 0.010 in. (0.25 mm). Slots, 0.25 in. (6.4 mm) long and 0.032 in. (0.8 mm) wide, should be cut at each corner of each opening to facilitate cutting of sharp corners by a standard utility

12、knife or single-edged razor blade. T 1007 sp-15 Sample location / 2 5.2 A typical template or die for sampling will allow samples to be cut in accordance with the 15 to 18 in. (38.1 to 45.7 cm) lane pattern across each roll to provide the size and number of samples specified in each test method. 6.

13、Report Report that sampling location complied with the requirements of this method, or, if different than specified, report the actual sample location and reason for deviation. 7. Precision A statement of precision is not applicable for this standard practice. 8. Keywords Fiber mats, Glass fibers, S

Additional information 9.1 Effective date of issue: April 21, 2015. 9.2 Changes in the 2015 edition included changes to the sampling sections, which eliminates the use of the template examples. Your comments and suggestions on this procedure are earnestly requested and should be sent to the TAPPI Standards Department.
