Foreword
GB/T 337 "nitric acid industry" is divided into two parts.
--- Part 1. Industrial nitrate concentrated nitric acid;
--- Part 2. Industrial dilute nitric acid nitric acid.
This section GB/T 337 - Part 1.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This Part replaces GB/T 337.1-2002 "industrial nitrate concentrated nitric acid." Compared with GB/T 337.1-2002, in addition to editorial changes
Outside the main technical changes are as follows.
--- Increasing the product type (see Chapter 4);
--- 97 nitrous acid content from 1.0% adjusted to 0.50% (see 52, 2002, version 3.2.);
--- Modify the content of nitrate measurement procedure (see 63, 2002 version 4.1.);
--- Revised measurement procedure nitrite content (see 64, 2002 version 4.2.);
--- Modified residue on ignition determining step (see 66, 2002 version 4.4.);
--- Modified products inspection rules (see Chapter 7, Chapter 5, 2002 edition).
This part is proposed by the China Petroleum and Chemical Industry Association.
This part of the National Standardization Technical Committee chemical inorganic chemicals Club (SAC/TC63/SC1) centralized.
This section is drafted. Hangzhou Longshan Chemical Co., Ltd., CNOOC Tianjin Chemical Research Institute, Hebei Jiheng Chemical Co. Seric
