Understanding IP Ratings

If you are familiar with scales or balances, you might have encountered ingress protection (IP) ratings at some point. You probably realize that an IP rating means some degree of dust and water protection for those devices. But you might be interested to find out a little more detail on the ratings and what they mean for weighing instruments.

Standards for defining these types of protection are set and regulated by the International Electrotechnical Commission. The IEC is the world's leading organization that prepares and publishes international standards for all electrical, electronic and related technologies.

When the internal mechanisms of these devices are protected against dust and water, they get an IP rating. The IP rating is a number that corresponds with a specific level of protection.

The degrees of protection are expressed as "IP" followed by a two-digit number. The numbers can vary depending on the amount of protection provided, but Adam's scales that feature IP ratings are manufactured specifically to meet the IP66 standard.

The rating's first digit (in Adam's case, it's a "6") provides a designation as to how well the product is protected against particulate matter, such as dust. A lower number signifies a lesser amount of protection. The chart below specifies the object size against which the device is protected.

 

Protection Against Solids

Index

Dust/Particle Protection

0

Not protected

1

Protected against solid objects greater than 50mm

2

Protected against solid objects greater than 12mm

3

Protected against solid objects greater than 2.5mm

4

Protected against solid objects greater than 1.0mm

5

Dust protected (small quantities OK)

6

Dust-tight

 

The second digit (another "6" for Adam) shows the extent to which the equipment is protected against water. Again, a lower number means less protection. The chart below specifies the amount of liquid against which the device is protected. When a product gets an IP66 rating, the device is not only dustproof, it is also waterproof to a certain extent.

 

Protection Against Liquids

Water Protection

0

No special protection

1

Water dripping/falling vertically

2

Water sprayed at an angle (up to 15 degrees from the vertical)

3

Spray water (any direction up to 60 degrees from the vertical)

4

Spray water from all directions (limited ingress OK)

5

Low-pressure water jets from all directions (limited ingress OK)

6

High-pressure jets from all directions (limited ingress OK)

 

Adam Equipment manufactures several products that offer dust and water protection. These products include Warrior washdown scales, WBZ washdown retail scales, and WBW washdown scales.
