IEC 61215-2 Walk-in Climate Chamber of Heat-Cold-Humidity

1. Introduction:

The climate chamber of heat - cold - humidity (hereinafter referred to as the climate chamber) is intended for carrying out climatic tests of photovoltaic modules. The climatic chamber will be operated under the following conditions:

- Ambient air temperature, °C: +15 ... +30;

- Relative air humidity,%: 45 ... 80;

- Atmospheric pressure: 84.0 ... 106.7 kPa (630 ... 800 mm Hg).
