IP protection Degrees

Most labs size their drip box using only the sample's base footprint — and that fails for two independent geometric reasons: the turntable's ≈100 mm eccentricity in IPX1, and the 15° tilt in IPX2. A 300×300 mm sample alone already requires a 750×750 mm box under IPX1. See the IEC 60529 geometry explained, and use Ormity and Dunel's free simulator to get the correct minimum drip box size for IPX1 and IPX2.
