T/SAEPI 006-2021 Molecularly-dispersed formaldehyde monitoring device for indoor use in civil environments

Scope

Scope: This document specifies the terms and definitions, appearance, electrical strength, electromagnetic compatibility, response time, indication error, repeatability, anti-interference, and test methods, inspection rules, and markings for civil indoor formaldehyde concentration detection devices, as well as their user manuals, packaging, transportation, and storage. This document applies to civil indoor formaldehyde concentration detection devices (hereinafter referred to as detection devices). This document does not apply to formaldehyde concentration detection instruments and equipment used in fields such as metrology and environmental monitoring. Main technical contents: 1. Response time: The time required for the detection device's indicated value to rise to 90% of the target concentration. 2. Indication error: The difference between the detection device's indicated value and the value measured by the standard method. 3. Repeatability: The ability of the detection device to provide similar indicated values under the same measurement conditions, expressed as the relative standard deviation. 4. Anti-interference: The change in the output value of the detection device after it is exposed to a certain concentration of interfering gases. 5. Test mode: The mode of products with a digital display of formaldehyde concentration (such as air purifiers, fresh air units, and air conditioners, etc.) that only provide formaldehyde concentration detection without other functions.
