GB/T 22814-2021Anti-rust base paper (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 22814-2008 "Anti-rust Base Paper". Compared with GB/T 22814-2008, the main technical changes are as follows.

---Added terms and definitions (see Chapter 3);

--- Adjusted the classification (see Chapter 4, Chapter 3 of the 2008 edition);

---Adjusted the quantitative range, according to plain paper and crepe paper respectively (see 5.1.1, 5.1.2, 2008 edition of 4.7);

---Adjusted the quantitative deviation (see 5.1.1, 4.7 of the 2008 edition);

---Deleted the transverse tensile strength and burst resistance indexes of crepe paper (see 4.7 of the 2008 edition);

---Revised the tightness and delivery moisture indicators (see 5.1.1, 5.1.2, 4.7 of the 2008 edition);

---I type anti-rust base paper increased the dust index (see 5.1.1, 5.1.2);

---Adjusted the sample handling requirements (see 6.1, 5.1 of the 2008 edition);

---Added the test methods for dustiness, appearance and paper roll requirements (see 6.11 and 6.14).

1 Scope

This standard specifies the terms and definitions, classification, requirements, test methods, inspection rules, marking, packaging, transportation and storage of anti-rust base paper.
