    Abstract - (Show below) - (Hide below)

    IEC 60721-2-2:2012 presents fundamental properties, quantities for characterization, and a classification of environmental conditions dependent on precipitation and wind relevant for electrotechnical products. This second edition cancels and replaces the first edition, published in 1988, and constitutes a technical revision. The main changes with regard to the previous edition are as follows:
    - subclause Precipitation: simplified;
    - data not possible to validate are removed;
    - subclause Wind: text rewritten;
    - Table 1 simplified and aligned with definition used by [1];
    - subclause Hail: data added;
    - formula changed;
    - formula for impact energy added;
    - subclause Snow: text changed and aligned with definitions used by [1];
    - Table 3 removed;
    - subclause Normal rain: text has been modified and numeric values removed;
    - subclause Driving rain: text has been modified and numeric values removed;
    - subclause Formation of ice: text has been modified and numeric values removed;
    - subclause Drifting snow: text added;
    - subclause Wind force: formula changed;
    - Figure 1 to 5 removed.
