Foreword

This standard replaces GB/T 15512-1995 "Evaluation of Enterprise save steel Technical Guidelines." This standard compared with GB/T 15512-1995, the main changes are as follows:

--- Standard name was changed to "evaluate the enterprise to save steel materials Technical Guidelines";

--- Increased steel material savings, steel-related terms and definitions steel material consumption, etc;

--- Increased evaluation principles (Chapter 4) and evaluation (Chapter 5);

--- Combined the original standard first chapter 5,6,7,8, and modify the content (Chapter 6);

--- Modify the content management requirements (Chapter 7). This standard by the National Standardization Technical Committee for Energy Management and focal points. This standard drafting units.

1 Scope

GB/T 15512-2009 is the Chinese national standard on technical guides for evaluating the saving of iron and steel product in enterprise, in the field of metallurgy. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 8 April 2009 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 December 2009. Classification: ICS 77.020, CCS H01. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the evaluation of conservation principles ferrous materials, evaluation and calculation methods, technical and administrative requirements. This standard applies to the steel material production, processing, use, circulation and recycling of scrap iron and steel units.
