Industrial furnaces and associated processing equipment - Method of measuring energy balance and calculating efficiency - Part 4 : furnaces with protective or reactive atmosphere

ISO 13579-4:2013 specifies general methodology for measuring energy balance and calculating the efficiency of the process involving furnaces with protective or reactive atmosphere as designed by the furnace manufacturers. This general methodology includes measurement methods, calculations (general calculation), and evaluation report. part of ISO 13579-4:2013 is not applicable to any efficiencies related to the process itself outside of furnaces with protective or reactive atmosphere.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
