To prepare standards related to the inherent and functional safety of the product and to the operating characteristics where such are associated with application safety. The scope covers the evaluation of automatic electrical control devices used in homes, buildings, appliances and other apparatus, electrical and non-electrical. The scope also covers products for industrial purposes when no dedicated product standards exist, such as that for central heating, air conditioning, process heating building automation, etc.
 

For clarity, electrical controls embody the aspects of initiation  (input), transmission (e.g. logic solver), and operation (e.g. switching device(s) or data output(s)) as defined in IEC 60730-1. There are two types of controls – closed-loop and open-loop controls, designed for various applications, as noted above. 

Additionally, the following products are also included under the scope:

1. Automatic electrical control devices, mechanically, electromechanically, electrically or electronically operated. These devices are responsive to or controlling parameters such as temperature, pressure, chemical, passage of time, humidity, light, electrostatic effect, flow or liquid level.
2. Automatic electrical control devices serving the starting of small motors that are used principally in appliances and apparatus for household and similar purposes. Such control devices may be built into, or are separate from, the motor.
3. Non-automatic control devices when such are associated with automatic control devices.
4. Automatic electrical controls used in application functions such as building automation for comfort living, energy management, photo-voltaic applications, battery management systems, alternate fuel applications, etc. Energy efficiency of the overall installation is not included within the scope. This is covered under the scope of TC23/SC23K.
5. Automatic electrical controls that use cloud-based technology to perform control functions.
6. Automatic electrical control devices that may be part of the gas train/path for alternate fuels such as hydrogen.
7. Sensors and sensing technology used on or in association with automatic electrical controls.

New or emerging trends in technology that may impact TC 72:

Cyber-security
 

Functional Safety
 

Expanded use of intelligence in products, and the linking of products by information technology & wireless solutions (“internet of things”). For example: AI, Machine learning, etc.
 

Products being made smaller and more compact
 

Wide band-gap semiconductors (WBGS) components

Following are several aspects of the business environment which influence the work of TC 72:

• electrical, EMC, functional safety and mechanical aspects
• the shorter life cycle of products

• IoT
  

  Cybersecurity issues

• products that communicate via the internet, wirelessly or other dedicated networks such as HBES/BACS networks
• the wide use of sensors in products for safety purposes and performance efficacy.
• the emerging trend of alternate fuels, DC technology, innovative materials for components, etc.

• Control and system manufacturers
• Test houses
• OEMs
• Regulators

Refer to section A above.

The table below illustrates various system approach aspects related to TC 72 (including relevance to ISO. It is not anticipated that an SEG or SyC will be required.

TC 72 publications are in line with clause 6.7 of Part 2 of the IEC/ISO directives, and with the requirements related to conformity assessment aspects.
 

TC72 publications will be used in IECEE.
 

TC72 standards include test specifications, reproducible test requirements, and test methods.
 

It is not likely that there will be special conformity assessment requirements generated by TC72 standards projects.
