CLASSIFICATIONS &

STANDARDS

IP code classifies the degrees of protection provided

against the intrusion of solid objects (including body

parts like hands and fingers), dust,

ccidental

ontact, and

water in electrical enclosures. In the code IP43, for example,

the first digit (4) describes the protection level against dust,

and the second digit (3) describes the protection against

water. If second digit is high, meaning good protection, then

the first digit is considered irrelevant and is marked with

an X (example IPX6).

FIRST DIGIT:

0 No protection

1 Protection against objects larger than 50 mm

2 Protection against objects larger than 12 mm

3 Protection against objects larger than 2.5 mm

4 Protection against objects larger than 1 mm

5 Dust protected

6 Dust tight

SECOND DIGIT:

0 No protection

1 Dripping water

2 Dripping water when tilted up to 15°

3 Spraying water; maximum angle 60°

4 Splashing water from all angles

5 Water jets

6 Powerful water jets

7 Immersion up to 1 m

8 Immersion beyond 1 m

The CE symbol means that the manufacturer or

importer confirms that the compliance on the product

meets the safety level stipulated in the European

regulations for that particular product group. Toys,

electric home appliances, life jackets, helmets and

other personal protective equipment are among the

product groups covered by the CE safety regulation.

The products in these the product groups must be CE

marked and the Swedish authorities are responsible

for market surveillance and the monitoring of full com-

pliance with the provisions for CE-marked products.

ROHS

The Restriction of Hazardous Substances directive

2002/95/EC on the restriction of the use of certain hazard-

ous substances in electrical and electronic equipment is

designated RoHS. The directive bans the use of certain Haz-

ardous substances in electrical and electronic equipment

released into the market from 1 July 2006. The scope of the

RoHS directive is linked to directive 2002/96/EC regarding

waste of electrical and electronic equipment (WEEE), by

the WEEE directive Annex 1A, which contains the product

categories covered by the directives.

ATEX

Short for Appareils destinés à être utilisés en

Atmosphères EXplosibles, the ATEX directive is a

European standard for treating equipment and work

areas where there’s a risk for explosive mixtures (e.g.,

gas leaks). Products certified to be used in potentially

explosive environments are classified differently depending

on which type they are or the protection that they have,

which environment they’re intended for (e.g., gas or dust),

temperature class, and the expected explosiveness of the

mixture, etc.

Areas where there’s risk that the atmosphere will become

explosive are divided into three zones where Zone 0 carries

the highest risk of an atmosphere explosion and Zone 2

carries the lowest risk. Products intended to be used in

these zones are classified into three categories depending

on the amount of protection that the product has. Products in

Category 1 is intended for use in Zone 0, etc. (G = gas)

ZONES PRODUCT CATEGORY

Zone 0 Category 1G

Zone 1 Category 1G or 2G

Zone 2 Category 1G, 2G or 3G

IECEX

IECEX corresponds to ATEX but is more globally imple-

mented.
