This document specifies the safety, design, construction, performance requirements and testing of Temperature Control Functions (TCF) and Combustion Product Discharge Safety Devices (TTB) for gas and liquid fuel burners and appliances burning one or more gaseous or liquid fuels, hereafter referred to as ‘TCF’ or ‘TTB’. It also describes the test procedures for checking compliance with these requirements. This document is applicable to AC and DC supplied TCF and TTB (for TCF and TTB supplied by stand-alone battery system, battery systems for mobile applications or systems which are intended to be connected to DC supply networks, see Annex I). This document is applicable to electronically based TTB and TCF only. For both TTB and TCF, the requirements in this document are applicable to the combination of sensing element and control.
