YY/T 1309-2016 in English

Interpretation of the core content of the standard

As a special supplement to the YY/T 0734 series of standards, this standard proposes 21 technical indicators for the ultrasonic cleaning module of the cleaner-disinfector. The main specifications are:

Analysis of key technical requirements

4.1 Ultrasonic cavity design

The standard stipulates that the cavity must meet: 120℃ high temperature tolerance, ΔT≤35℃ temperature rise limit, and mandatory observation window/liquid level indicator. In practical applications, it is recommended to use sintering adhesive bonding process to ensure the reliability of transducer connection.

4.5-4.7 Power parameters

The power-to-volume ratio is calculated using the formula P_H=P_p/V, where:

• Input power measurement requires the use of a power meter with an accuracy of ≥1%
• The transducer efficiency η should be provided in writing by the manufacturer

Implementation recommendations

Key points for manufacturers’ compliance

1. A frequency-power correspondence curve must be provided
2. Glass instrument compatibility testing must include 20 cycle tests
3. Noise testing must be measured in four directions at a distance of 1m
