Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national 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
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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).

This document was prepared by Technical Committee ISO/TC 244, Industrial furnaces and associated
processing equipment, in collaboration with the European Committee for Standardization (CEN)
Technical Committee CEN/TC 186, Industrial thermoprocessing - Safety, in accordance with the
Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 13577-4:2014), which has been technically
revised.
The main changes are as follows:
— to provided better clarity methods B and C were combined to create a new method BC,
— Annex E was rewritten to provide several new examples to better reflect the intent for previously
misunderstood elements,
— Annex B was modified to include clearer language and examples of normative wiring. The original
Annex F was merged,
— created wording to provide a better alignment with IEC 62061, IEC 61511, and ISO 13849-1.

Introduction
This document was developed to specify the requirements of a protective system, which is a safety-
related control system (SCS) of industrial furnaces and associated processing equipment (TPE). It is
intended that in designing the protective system of TPE, manufacturers of TPE choose from the three
methods provided in this document. Requirements for safety-related control functions of TPE are
specified in ISO 13577-1, ISO 13577-2, and ISO 13577-3.
This document is intended to be used jointly with ISO 13577-1, ISO 13577-2 and ISO 13577-3. Since the
other parts of the ISO 13577 series are type-C stand
