IEC 60529 IP CODE
IEC 60529 is the most commonly used international standard as the protection regulation of product case , so it is also called "International Protection Level, IP Code".
When designing most of electronic and electrical products, based on safety or reliability requirements, the following considerations are taken into account:
- Degrees of protection against foreign objects
- Degrees of protection against access
- Degrees of protection against water
The above improper product design or use may have an impact on the product itself (such as performance degradation or failure) or human safety hazards (such as electric shock, fire). Therefore, products that will be exposed to outdoor or humid environments are designed for use. Need to consider and evaluate the IP Code.
Recommended products for testing (applicable to products with rated voltage less than 72.5KV):
- Outdoor eletrical products and lamps: street lights, garden lights, power transmission and distribution control boxes, pumps, outdoor units of air conditioners, outdoor LED billboards and traffic signs, etc.
- Communication and surveillance equipment installed in a non-protected environment: antennas, broadcasting devices, surveillance cameras, etc.
- Portable devices used in military regulations, industrial regulations and outdoor operations: mobile phones and radios, GPS, PDA, Tablet PC, UMPC
- Equipment that may cause personal injury due to improper operation: mobile phones, laptops, due to the devices have lithium rechargeable batteries, and may infiltrate due to accidental liquid spills or rain, causing the battery to short-circuit and catch fire; or due to improper maintenance, the procedure causes the hand tool to contact with the charged body inside the power supply, etc.
JIS C0920 / CNS 14165
Evaluation after the test:
- Generally, if there is no special requirement in the product standard, the requirements of IP5X dust test are:
- Talcum powder must not accumulate or enter the product. When it is replaced by any other dust entering, it may cause harm to the normal operation of the product or product safety
- There must be no talcum powder entering, which may reduce the creeppage distances and does not meet the safety requirements
- Generally, if there is no special requirement in the product standard, the requirements of IP6X dust test are:
- Do not allow any dust to enter the case
- If there is no special regulation in the product standard, the requirements of IPX1 ~ IPX9 waterproof test are:
- Must not affect the operation of the product
- Do not harm the safety of the product
- Do not allow water enter the insulating surface, which shortens the creepage distances
- Do not allow water enter, contacting with live electrical parts or coils that are not waterproof
- Do not allow water to accumulate at the cable terminal or enter the cable
