Introduction
Analysis of the core content of the standard
SN/T 3195.1-2012 specifies the energy consumption test method for imported and exported household electric ovens, focusing on the three functional modes of conventional heating, forced air circulation and hot steam.
Key Technical Points
| Test Items | Conventional Heating | Forced Circulation | Hot Steam |
|---|---|---|---|
| Target Temperature Rise(ΔT) | 180K | 155K | 155K |
| Standard Deviation Requirement | <0.050kW·h | ||
| Thermocouple Accuracy | ±1.5K(IEC 60584-2 Class 1) | ||
Standard load specifications
The standard load is made of Hipor material, key parameters:
- Dry mass: 920±75g
- Water absorption: 1050±50g
- Dimension tolerance: ±0.5mm
- Thermocouple insertion depth: 32mm
Note: Before each test, it needs to be soaked in 5±2℃ water for 8 hours to ensure consistency of moisture content.
Implementation recommendations
- The test environment should be maintained at 23±2℃ and avoid direct sunlight
- Multi-cavity ovens need to test each cavity separately
- Voltage fluctuations should be controlled within the range of ±1% of the rated value
- Standard load drying requires forced ventilation at 175℃ for 8 hours
Background of standard evolution
This standard is formulated with reference to IEC 60350:2009 and EN 50304:2009. The main differences are:
- Added hot steam function test requirements
- Strengthened standard load preparation specifications
- Introduced linear regression method for calculating energy consumption
