GB/T 2599--1997
This standard is revised on the basis of GB2599-81 "Tri-Mixed Cresols". The name of the standard was changed from "Tri-Mixed Cresols" to "Industrial Cresols"; the standard content has been expanded to include scope, reference standards, marking packaging, transportation, storage and safety precautions; the technical content has been appropriately adjusted, and the first-grade product index of distillation test and moisture content has been cancelled; the second-grade product index of neutral oil content has been cancelled; and the moisture index has been revised to 1.0%. This standard will replace GB2599-81 from the date of its entry into force. This standard was proposed by the Ministry of Metallurgical Industry.
This standard is under the jurisdiction of the Information Standards Institute of the Ministry of Metallurgical Industry. The drafting units of this standard are: Shanghai Meishan (Group) Co., Ltd. and the Information Standards Institute of the Ministry of Metallurgical Industry. The main drafters of this standard are: Zhang Yi and Sun Wei. This standard was first issued in 1981.
