| IEC Numbering System |
The International Electrotechnical Commission (IEC) changed its numbering
system in 1997 by adding 60,000 to their existing numbers. For example,
the designation IEC 320 is the same as IEC 60320. The change was made to
harmonize the IEC system with the European Normalisation (EN) system.

| IP Numbering System |
The International or Ingress Protection Rating consists of the letters IP
followed by two digits and an optional letter defined in International
standard IEC 60529. The first digit indicates the level of protection against
solids. The second digit indicates the level of protection against liquids.
Letters A, B, C, and D can be appended to classify only the level of
protection against access to hazardous parts by persons.
The IP44 connector protects against solids greater than 1mm and splashing
liquids. The IP67 connector protects against dust and immersion in water to
a depth of 1 meter. IEC 60529 provides more details than marketing terms
such as Splashproof (IP44) and Watertight (IP67). |
