COMMERCIAL

TECHNICAL EXPLANATIONS IP ( Ingress Protection ) ratings are used to define the sealing effectiveness of electrical products against intrusion from solids (fingers, tools, dust) and liquids. This is shown as a 2 digit code with each numeral shown below. The 1st numeral is for protection from solids and the 2nd from liquid.

SOLIDS

LIQUIDS

Protected against a solid object greater than 50mm such as a hand.

Protected against vertically falling droplets of water. Limited ingress permitted.

Protected against vertically falling drops of water with enclosure tilted up to 15 degrees from the vertical. Protected against sprays of water up to 60 degrees from the vertical. Limited ingress permitted for three minutes.

2 Protected against a solid object 3 Protected against a solid object 4 Protected against a solid object greater than 1mm such as a wire.

2 3 4 5 6

greater than 12.5mm such as a finger.

greater than 2.5mm such as a screwdriver.

Protected against water splashed from all directions. Limited ingress permitted.

5 Dust Protected. Limited ingress of dust permitted. Will not interfere with operation of the equipment. Two to eight hours.

Protected against jets of water. Limited ingress permitted.

Water from heavy seas or water projected in powerful jets shall not enter the enclosure in harmful quantities. 7 Protection against the effects of immersion in water between 15cm and 1m for 30 minutes. 8 Protection against the effects of immersion in water under pressure for long periods.

6 Dust tight. No ingress of dust. Two to eight hours.

TP(a) ( Thermal Protection ) ratings relate to thermoplastic diffusers. TP(a) diffusers must self-extinguish and any flaming and afterglow must not exceed five seconds once the source of flame is removed. This is to prevent the spread of fire. UGR (Unified Glare Rating ) is a value, commonly shown in steps of 3, that is used to calculate the level of glare in lighting applications. Glare, simplified, is the discomfort a user receives from lighting directly (field of vision) and indirectly (reflectances). UGR is a very elusive figure to estimate, as this is based on the application. Therefore UGR can only be calculated by doing lighting designs, values listed are to be used as a guide. The best way of reducing glare in lighting is to use a prismatic/reeded diffuser.
