Technical Specification for Intelligent Level of Household Range Hoods

The standard is published by the China Standardization Association (CAS) on October 10, 2019.
The standard is implemented by the CAS, which is a national social organization that organizes domestic and international standardization activities.

Smart Level Evaluation

The smart level of a household range hood is determined by its intelligent functions, which are evaluated based on the requirements and detection methods specified in the standard.
The smart level is represented by a smart index, which is a combination of letters and numbers (e.g., "5A0B" or "nB").

Intelligent Functions

There are 19 intelligent functions, including:
- Functional safety
- Information technology security
- Self-diagnostic function
- Running mode adaptation (smart mode)
- Network module OTA (over-the-air) update
- Appliance control function OTA update
- Health maintenance reminder
- Cleaning function
- User habit learning function
- Voice control function
- Remote control function
- Multimode interconnection function
- Smoke duct self-adaptation function
- Intelligent ventilation function
- Multi-platform interconnection function
- Smoke alarm interconnection function
- Gesture control function

Evaluation Criteria

Each intelligent function has a specific evaluation criterion, which includes a scoring rule and a passing score.
The scoring rule is based on the degree of implementation of the intelligent function, with a maximum score of 20-50 points depending on the function.
The passing score is 3B or above, which indicates a high level of smartness.

Safety and Security

The standard requires that the household range hood meets the safety and security requirements specified in the standard, including functional safety, information technology security, and health maintenance.
The standard also requires that the household range hood has a self-diagnostic function to detect and report any faults or errors.

OTA Update

The standard requires that the household range hood has an OTA update function, which allows the user to update the software and firmware remotely.
The OTA update function should be secure, reliable, and efficient, and should not affect the normal operation of the household range hood.

User Habit Learning

The standard requires that the household range hood has a user habit learning function, which can learn and adapt to the user's habits and preferences.
The user habit learning function should be able to learn the user's usage patterns, including the time, mode, and duration of use.

Voice Control

The standard requires that the household range hood has a voice control function, which can accept voice commands and execute corresponding actions.
The voice control function should be able to recognize and respond to voice commands accurately and efficiently, and should have a low error rate.
