GB/T 2945-2017Ammonium nitrate (English PDF)

Foreword

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

This standard replaces GB/T 2945-1989 "ammonium nitrate", compared with GB/T 2945-1989 compared to the main technical changes are as follows.

--- Increasing the warning, the appearance of crystalline ammonium nitrate requirements (see 3.1.1), bulk product sampling (see 5.3.2), product quality standards Indicators of the decision (see 5.5.1), transport requirements (see 6.3);

--- Increasing the determination of ammonium nitrate content (reduction - distillation - titration), by calculating the total nitrogen calculation of ammonium nitrate as the arbitration method;

--- Modify the normative references (see Chapter 2), agricultural grade ammonium nitrate and technical indicators (see Chapter 4), packaging logo And packaging specifications (see 7.1, 7.2 and 7.4).

1 Scope

This standard specifies the requirements of ammonium nitrate, test methods, inspection rules, marking, packaging, transportation, storage and safety requirements.

This standard applies to ammonia and nitric acid and ammonium nitrate obtained.
