  1. electrical heated elements as part of the appliance;

  2. outdoor appliances;

  3. appliances supplied at pressures greater than the maximum pressure of the test gases;

  4. cook stoves, covered by the standards being developed in ISO/TC 285

In general, it does not take into account children playing with the appliance.

NOTE 1

For requirements of electrical safety refer to the IEC 60335 standard series.

NOTE 2

Attention is drawn to the fact that

  1. ? for appliances intended to be used in vehicles or on board of ships or aircrafts, additional requirements could be necessary;

  2. ? in many countries additional requirements are specified by the national health authorities, the national water supply authorities and similar authorities

This document does not cover requirements relating to gas cylinders, their pressure regulators and their connections.

This document does not cover requirements for gas installation.
