Terminology3.1 DefinitionsFor definitions of terms used in this stan-dard, refer to Terminology D 1711.4. Classification4.1 Four types of paper and paperboard are covered by thisspecification,
6、as shown in Table 1. The material is available insheets, pads, or rolls.5. Ordering Information5.1 Orders shall specify the type, including whether waterfinish or not (see Note 1), nominal thickness, form, width,length (for sheets), nominal outside diameter, and core insidediameter (for rolls).NOTE
7、1Water finish is not available with certain combinations ofKraft type and thickness. In general, water finish is restricted to paper andpaperboard in the higher density ranges, that is, Types III and IV.6. Materials6.1 The material shall be natural unbleached sulfate paper orpaperboard, free of dyes
8、, pigments, fillers, or sizing. It may befurnished either with water-finish or without.7. Detail Requirements7.1 The material shall conform to the chemical, physical,and electrical requirements specified in Tables 1-4, when testedin accordance with the methods prescribed in Section 11.8. Interpretat
9、ion of Numerical Requirements8.1 Unless otherwise stated, all specified limits in thisspecification apply to the average of determinations applicableto a sample as defined.9. Workmanship, Finish, and Appearance9.1 The material shall be uniform in thickness, density,formation, and texture. The materi
10、al shall be as free of welts,wrinkles, creases, holes, slime spots, stains, shives, weak spots,blisters, tears, cuts, and other defects; and from resin, dirt,carbon, rubber, metal particles, corrosive substances, or other1This specification is under the jurisdiction of ASTM Committee D09 onElectrica

Retest and Rejection13.1 If the results of any test do not conform to therequirements prescribed in this specification, at the option ofthe manufacturer that test shall be repeated on two additionalsets of specimens from the same batch or shipment, each ofwhich shall conform to the requirement
20、s specified. If either ofthese two additional sets of specimens fails, the material maybe rejected at the option of the purchaser.13.2 Notice of failure of material based on tests made inaccordance with this specification shall be reported to themanufacturer within 3 weeks from receipt of the materi
21、al bythe purchaser. Any portion of an accepted shipment of materialthat is subsequently shown not to have been in accordance withthis specification at the time of receipt may be rejected,provided the manufacturer is notified within 90 days from thedate of receipt of the material by the purchaser.14.
