T/CAQI 160-2020 Household gas rapid water heater whole process silent classification evaluation specification
Basic Information
Scope
Scope: This document specifies the technical requirements and test methods for the full-range silent grading of household gas instantaneous water heaters. This document is applicable to household gas instantaneous water heaters with a rated heat load not exceeding 70kW; Main technical content: Conduct tests according to the method specified in 5.2 to measure the noise value of the appliance. The silent grading of the appliance is divided into three levels, with the noise level of Level 1 being the highest. The grading indicators are shown in Table 1. The noise values on the front and side of the appliance when it is operating at its rated load, as well as the noise value during the preheating process, should all meet the requirements of a certain level of silent performance grading. If the levels of the various individual indicators differ, the overall rating shall be determined as the lower level.
