I am inquiring on any UL standard that specifies a maximum allowable force, or torque setting for a moving barrier that a machine operator can be exposed to. The only other application that quickly comes to mind is for automatic garage door openers, which provide for automatic retraction of door if it comes in contact with a person, car or other obstacle while closing.
Does UL have a directory listing approved " Remote Controlled Garage Doors & Safety Controls" ? If so what standard does UL approve them to. The only standard I have heard of is an Austrian Standard entitled "Garage Door and Industrial Door Driving Units; Controls and Safety Devices" , Std no. OE NOM B 1205, part 2, 1991; plus 1991appendix. If UL doesn't have a specific standard for the above subject, is there a related UL standard used, or is there a standard published by ANSI, Factory Mutual etc.? Please reply via this email request to the email address.................... [email protected]; phone number 508-486-1060, x616; or fax 508-486-0292. Thank you for your anticipated help.
