IEC60884-1 Non-Metallic Material External Parts Ball Pressure Test Apparatus
Product information:
The ball pressure test apparatus conforms to many standard requirements, such as IEC60884-1, IEC60335-1, IEC60950 and so on.
Application: external parts of non-metallic material, parts of insulating material supporting live parts including connections and parts of thermoplastic material providing supplementary insulation or reinforced insulation shall withstand this ball pressure test.
Technical Parameters:
| Weights | 20N±0.2N |
| Pressure ball diameter | Ф5mm (R2.5mm), conforms to ISO 3290 |
| Pressure ball material | Hardening steel |
| Other parts material | Stainless steel |
| Support dimensions | Ф50 mm X100mm with an insertion hole for thermocouple |
Test Procedures:
A. Turn on the power supply of the oven (the oven is prepared by the operator).
B. Mount a separate thermocouple into the thermocouple hole, where is the centre of the test specimen support approximately 3mm below the surface, to check that the temperature of the test specimen support does not significantly deviate from the test temperature.
C. Set the required temperature on the controller of the oven. Conduct the test in air, within a tolerance of ±2°C. The heating oven, ball pressure test apparatus and test specimen support shall be maintained at the test temperature for 24 h or until thermal equilibrium is reached, whichever occurs sooner.
D. When thermal equilibrium conditions are reached, place the test specimen on the approximate centre of the test specimen support so that its upper surface is horizontal. Gently lower the pressure ball on to the approximate centre of the test specimen, ensure that no conditions exist that will cause the pressure ball to move other than in a downward direction during the test. The installation of the test specimen shall be performed in as short a time as practicable to ensure that there is no significant temperature drop of the heating oven and test specimen support. The ball pressure apparatus is pressed against this surface with a force of 20N
E. After the specimen has been heated at the required temperature for 60min+2min/0min, remove the pressure ball from the test specimen and within 10s immerse the test specimen in water maintained at 20°C±5°C. Following an immersion period of 6min±2min remove the test specimen from the water and eliminate all traces of water.
Notice
1. After each test, the ball pressure test apparatus shall be cleaned using a clean dry cloth.
2. R2.5 steel ball is ball bearing steels, pay attention to rust protection.
3. The support surface is kept bright, clean and smooth.
4. Prevent foreign bodies blocked the Ф 2.5 thermocouple hole.
5. Prevent balancing weight screws loosen.
