Test Procedure (Excerpted from IEC60335-2-2 Clause 21.102)
- Connect one end of the hose to the crank mechanism’s connecting rod as shown in Figure 101. The crank rotates at a speed of 30 RPM, causing horizontal back-and-forth movement within a distance of 300 mm.
- Support the hose with a rotating smooth roller covered by an abrasive cloth belt moving at a speed of 0.1 m/min. Use corundum particle size P100 abrasive as per ISO6344-2 standards, and hang a 1 kg weight at the other end of the hose while guiding it to prevent rotation.
- Conduct the test for 100 rotations, ensuring that basic insulation is not exposed post-test, followed by an electrical strength test as per clause 16.3 between connected conductors and saline solution.
Maintenance Notes
- Cleaning: Keep the machine clean at all times to ensure optimal performance.
- Rust Prevention: Regularly spray anti-rust oil on metal parts and standard interchangeable parts after use.
- Lubrication: Periodically add lubricating oil to all rotating parts of the machine.
