■ IEC (International Electrotechnical Commission) Standards
IEC 60529: 2001
(A) First Digit: Degree of Protection from Solid Materials
(B) Second Digit: Degree of Protection Against Water
Degree Protection

No protection
1
Protects against penetration of any solid object such as a hand that is 50 mm or more in diameter.
2
Protects against penetration of any solid object, such as a finger, that is 12.5 mm or more in diame-
ter. Even if finger or other object 12 mm in diameter penetrates, it will not reach a hazardous part.

mum angle of 60 from verti-
cal towards the product.
