THREE RESISTANCE TESTS ON THE FOG LIGHTS IN THE CEVLAB LABORATORIES

We analyzed the resistance to vibrations, chemical agents and pressure washer.

RESISTANCE TO CHEMICAL AGENTS
This test checks the body and lens resistance to these substances: radiator fluid, 4T 10W 30 engine oil, petrol, E 10 petrol, DOT 4 brake oil and bodywork wax. In the photo, the laboratory technician Samuele Bertoni is applying the various substances with a soft cloth over the entire external surface. The agents are left to act for 24 hours, except the brake oil, which is only applied for one hour. At the end, any deposits are removed with water and dried with a soft cloth. The sample must not show any cracks, discolorations, swellings, bubbles, halos or other alterations.

HIGH PRESSURE WASHER RESISTANCE
This test is more severe than the waterproofing tests and simulates washing the motorcycle. The spotlight (not in operation) is fixed to the support through its hooking systems and is subjected to a jet of water at 60 °C, with a flow rate of 14÷16 l/min and a pressure between 80 and 100 Bar. The lance is placed 50 cm from the device under test. The duration is 30 s for each cardinal point, for a total of two minutes. At the end there should be no traces of water ingress. Immediately after the test, by switching it on for 30 minutes, any formation of internal condensation from infiltrations is verified. No deposits should appear even in the 20 minutes following switching off.

VIBRATORY BENCH
The 24-hour vibration resistance test is used to verify the resistance to breakage or alterations of the samples. The spotlights are fixed to the support through their own hooking systems, respecting the assembly instructions and to the prescribed tightening torque, if indicated. The machine vibrates at a frequency between 50 and 500 Hz, generating acceleration of up to 10g. The vibration occurs for 8 hours on each axis, in the last fraction the spotlight is powered and is switched on and off every 10 minutes.
