4 Use environment
4.1 General principles
When fire electronic products (hereinafter referred to as "products") need to be classified according to the use environment, they should be classified according to the use environment conditions specified in this chapter.
4.2 Normal use environment
4.2.1 Temperature Environment
The temperature range of the surrounding air of products used indoors should cover -10℃~40℃.
The temperature range of the surrounding air of products used outdoors should cover -40℃~50℃.
Note: Ambient air temperature refers to the temperature of the air surrounding the product, usually measured without the direct influence of external heat sources.
4.2.2 Humidity environment
When the temperature of the surrounding air of the product used indoors is 40℃, the relative humidity should not exceed 93%.
When the surrounding air temperature of outdoor products is 25℃, the relative humidity reaches 100% in a short time.
4.2.3 No pollution environment
There are no pollution sources that intermittently or continuously affect the detection parameters of detector products, and the total current harmonic content within the 20th order of distribution lines is not higher than 5%.
4.2.4 Mechanical vibration environment
In industrial and civil buildings, the vibration conditions of mechanical equipment, structures or systems under operation or external excitation, including the frequency, amplitude, direction, time characteristics, etc. of vibration, and the dynamic response generated and its impact on the surrounding environment.
4.2.5 Electromagnetic environment
In industrial and civil buildings, the sum of all electromagnetic phenomena in a specific space is the basic physical environment for the operation of electronic systems.
4.3 Special use environment
4.3.1 Special temperature operating environment
Exceeds the temperature environment specified in 4.2.1.
4.3.2 Condensation and dripping use environment
An environment that causes condensation on or inside the product and dripping water to the product surface.
4.3.3 Pollute the environment
Environments with pollution sources that intermittently or continuously affect the detection parameters of detector products.
4.3.4 Microorganisms attack the environment
An environment in which microorganisms invade the internal structure of the product and multiply, resulting in abnormal function or decreased reliability of the product.
4.3.5 Mold attacks environment
An environment in which the performance of the product is reduced or functional failure is caused by the growth of mold and the degradation of the product materials by its metabolites.
