On January 5th CSA Group published the first edition of particular requirements for rechargeable battery-operated commercial robotic floor treatment machines with traction drives. CSA 22.2 - 336 is a National Standard of Canada.
Why Should I Care?
If you are a robotics engineer working for a company planning to sell floor treatment machines in North America (including sweeping, scrubbing, wet or dry pickup, polishing, application of wax, sealing products, and powder-based detergents or shampooing) then this standard contains important test requirements for you.
Is it a Legal Requirement?
It is not.
Why Should I Care Then?
Occupational Safety and Health Act in the USA and the Canadian Electric Code are legal requirements. All electrically controlled devices or systems in the USA must be approved.
