| Table 2: The JIS Scale of Water Resistance | |
| The Japan Industrial Standards (JIS) for water resistance uses a scale from 0 to 8 to quantify the level of moisture protection built into each product. If a product has been tested against this standard, or according to the similar International Protection Code (IPX), its waterproofness designation is usually listed on the product spec sheet. | |
| JIS-0: | No special protection. |
| JIS-1: | Vertically dripping water shall have no harmful effect (drip-resistant 1). |
| JIS-2: | Dripping water at an angle up to 15 degrees from vertical shall have no harmful effect (drip-resistant 2). |
| JIS-3: | Falling rain at an angle up to 60 degrees from vertical shall have no harmful effect (rain resistant). |
| JIS-4: | Splashing water from any direction shall have no harmful effect (splash resistant). |
| JIS-5: | Direct jetting water from any direction shall have no harmful effect (jet resistant). |
| JIS-6: | Direct jetting water from any direction shall not enter the enclosure (watertight). |
| JIS-7: | Water shall not enter the enclosure when it’s immersed under defined conditions (immersion-resistant). |
| JIS-8: | The equipment is usable for continuous submersion in water under specified pressure (submersible). |
