IEC 60529-----IP Testing

IEC 60529 is an international standard designed to give products a determined International Protection Marking according to the IP Code rating. This standard tests the sealing effectiveness of enclosures of electrical equipment against the intrusion of solid particles and liquid.

 IPX1: This rating illustrates the item is protected against vertically-falling liquid drops, meaning any that fall on the item will have no harmful effect.
 IPX2: This rating extends IPX1 by ensuring protection against falling liquid drops at an angle up to 15 degrees.
 IPX3: This rating is given when an item is safe from ingress from spraying liquid. This is tested by spraying water at an angle up to 60 degrees of vertical and establishing that no harm came from this. The spray can come in an oscillating pattern with a flow rate that depends on the item tested.
 IPX4: This rating extends IPX3 to include protection against ingress from splashing liquids. It is tested by establishing that splashed water has no harmful effect on the item.
 IPX5: This rating applies to items that are protected against ingress from jets of liquid. It is given after testing with water jets, and it shows there were no harmful effects.
 IPX6: This rating is given for items that can provide protection against ingress from powerful jets of liquid. It’s an extended version of IPX5. The water pressure in this test can reach 14.5 pounds per square inch (PSI).
 IPX7: This rating goes further and indicates protection from temporary immersion in liquids. The rating is given after immersing an item in 1 meter of water for 30 minutes with no harmful effects.
 IPX8: This rating extends the IPX7 rating for water immersion to a greater depth and longer periods of time. The conditions of the water immersion are agreed upon between the manufacturer and the testing facility. The specifications have to be marked plainly on the product.

 IP5X: This rating applies to items in which hazardous parts cannot be accessed even with a wire, and protection against ingress from dust is also applicable. This is tested using a 1.0 mm access probe and by inspection to ensure any dust that enters would not interfere with the part’s functionality.
 IP6X: This rating is much like IP5X with the exception that the item is completely sealed off from dust. There can be no ingress of dust at all.

DIN 40050-9-----High Pressure Steam Jet Cleaning 
Covers degrees of protection of electrical equipment of road vehicles against foreign objects, water and access.
 

ASTM D951-----Water Resistance of Shipping Containers by Spray Method 
ASTM D951 is used to determine the water resistance of shipping containers and determines their ability to resist deterioration caused by water and the container’s ability to protect contents from water. Frequently used in conjunction with other tests such as drop test, inclined impact test, vibration or compression tests. 

ISO 20653 
ISO 20653:2013 applies to degrees of protection (IP code) provided by enclosures of the electrical equipment of road vehicles

MIL-STD-810F test standard – method 510.4
This method includes three test procedures, Procedure I (Blowing Dust), Procedure II (Blowing Sand), and Procedure III (Settling Dust). Determine the procedure(s) to be used.
