16、standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International

17、 organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules g

18、iven in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at leas

20、4, Industrial furnaces and associated thermal processing equipment. ISO 13579 consists of the following parts, under the general title Industrial furnaces and associated processing equipment Method of measuring energy balance and calculating efficiency: Part 1: General methodology Part 3: Reheating

21、furnaces for steel Part 2: Batch-type aluminium melting furnaces Part 4: Furnaces with protective or reactive atmosphere BS ISO 13579-1:2013ISO 13579-1:2013(E) vi ISO 2013 All rights reservedIntroduction Prevention of global warming is a significant issue which needs to be solved on the world scale.

22、 For this purpose, it is necessary not only to reduce energy consumption dramatically, but at the same time also ensure a convenient and comfortable daily life for everyone. It is critical to use energy as efficiently as possible to fulfil these requirements. Although industrial furnaces play an imp

23、ortant role in maintaining everyones life, on the other hand, they consume a great amount of energy. In order to tackle the above-mentioned issues, it is important to establish an International Standard (i.e. the ISO 13579 series), which specifies the energy efficiency of industrial furnaces in a re

24、asonable manner, control energy consumption by using the collected measurement data based on ISO 13579 (all parts), and improve efficiency. Furthermore, this part of ISO 13579 can be applied as a fair guideline for utilizing the Clean Development Mechanism (CDM), which was developed under the Kyoto

25、Protocol24for measures used to prevent global warming. All calculations within ISO 13579 (all parts) are based on the location of equipment under reference conditions. NOTE For equipment intended to be installed above or below sea level, it is expected that the impact of the elevation be calculated

26、for that location.

27、general methodology for measuring energy balance and calculating the efficiency of the process involving industrial furnaces and associated processing equipment as designed by furnace manufacturers. This general methodology includes: measurement methods; calculations (general calculation); an energy

28、 balance evaluation report. This part of ISO 13579 is not applicable to any efficiencies related to the process itself outside of industrial furnaces and associated processing equipment (e.g. in a rolling mill process, the reheating furnace is intended to be the only part covered by this part of ISO
