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.
What is in the Standard?
Many of the requirements apply to both manual and robotic machines including such things like electrical safety, battery safety, mechanical strength and construction.
How Do I Get a Copy?
The standard is available from the CSA Group website at or by searching for “336-17” on the CSA Group Store. Please support them and consider licensing a copy of this document. The price is very reasonable at ~100 USD and the CSA do valuable work.
I’ve bought a copy CSA 336, it references 26 other standards do I have to buy all of those too and how much will that cost?
This table lists the standards directly referenced by CSA 336. In North American they are available for purchase from ANSI for approximately $10,000[1].
