Y/T 0471.5-2017 is a newly updated standard, which specifies the experimental method for evaluating the bacteria-inhibiting performance of the contact wound materials claimed to have bacteria-inhibiting performance. The bacteria-inhibiting test device can simultaneously meet the four test methods of wet bacteria-inhibiting, dry bacteria-inhibiting, semi-wet (dry outside and wet inside) bacteria-inhibiting, and semi-wet (wet outside and dry inside) bacteria-inhibiting.
Standard:
EN 15194:Cycles - Electrically power assisted cycles - EPAC Bicycles
ISO 4210:Cycles - Safety requirements for bicycles
UL 2849:Standard for Electric Bicycles and Electric Scoooters
ECE R50:Uniform provisions concerning the approval of front position lamps, rear position lamps, stop lamps, direction indicators and rear-registration-plate illuminating devices for vehicles of category L
Principle:
The sample was placed between two collets of a hemispherical glassware, a certain amount of standard bacterial solution was added to one side of the ware, and liquid medium was added to the other side, and the turbidity in the liquid medium was checked after a certain period of time
Or scrape the liquid to check for bacterial growth.
Advantages:
Ensures compliance with critical safety and performance standards for e-bike lighting.
Provides accurate and repeatable measurements of photometric and electrical parameters.
Allows for comprehensive evaluation of light distribution and beam patterns.
Facilitates durability testing under simulated environmental and mechanical stresses.
Supports efficient research and development of innovative and reliable lighting solutions.
Contributes to enhanced rider safety and visibility in various conditions.
Helps in meeting regulatory requirements for market access and product certification.
