CHAPTER II--CONSUMER PRODUCT SAFETY COMMISSION
PART 1211--SAFETY STANDARD FOR AUTOMATIC RESIDENTIAL GARAGE DOOR
OPERATORS--Table of Contents
Subpart A--The Standard
Sec. 1211.10 Requirements for all entrapment protection devices.
(a) General requirements. (1) An external entrapment protection
device shall perform its intended function when tested in accordance
with paragraphs (a) (2) through (4) of this section.
(2) The device is to be installed in the intended manner and its
terminals connected to circuits of the door operator as indicated by the
installation instructions.
(3) The device is to be installed and tested at minimum and maximum
heights and widths representative of recommended ranges specified in the
installation instructions. For doors, if not specified, devices are to
be tested on a minimum 7 foot (2.1 m) wide door and maximum 20 foot (6.1
m) wide door.
(4) If powered by a separate source of power, the power-input supply
terminals are to be connected to supply circuits of rated voltage and
frequency.
(5) An external entrapment protection device requiring alignment,
such as a photoelectric sensor, shall be provided with a means, such as
a visual indicator, to show proper alignment and operation of the
device.
(b) Current protection test. (1) There shall be no damage to the
entrapment protection circuitry if low voltage field-wiring terminals or
leads are shortened or miswired to adjacent terminals.
(2) To determine compliance with paragraph (b)(1) of this section,
an external entrapment protection device is to be connected to a door
operator or other source of power in the intended manner, after which
all connections to low voltage terminals or leads are to be reversed as
pairs, reversed individually, or connected to any low voltage lead or
adjacent terminal.
(c) Splash test. (1) An external entrapment protection device
intended to be installed inside a garage 3 feet or less above the floor
shall withstand a water exposure as described in paragraph (c)(2) of
this section without resulting in a risk of electric shock and shall
function as intended. After exposure, the external surface of the device
may be dried before determining its functionality.
(2) External entrapment protection devices are to be indirectly
sprayed using a hose having the free end fitted with a nozzle as
illustrated in figure 2 and connected to a water supply capable of
maintaining a flow rate of 5 gallons (19 liters) per minute as measured
at the outlet orifice of the nozzle. The water from the hose is to be
played, from all sides and at any angle against the floor under the
device in such a manner most likely to cause water to splash the
enclosure of electric components. However, the nozzle is not to be
[[Page 328]]
brought closer than 10 feet (3.05 m) horizontally to the device. The
water is to be sprayed for 1 minute.

(d) Ultraviolet light exposure test. A polymeric material used as a
functional part of a device that is exposed to outdoor weather
conditions shall comply with the Ultraviolet Light Exposure Test
described in the Standard for Safety for Polymeric Materials--Use in
Electrical Equipment Evaluations, UL 746C, 4th ed., dated December 27,
1995. This incorporation by reference was approved by the Director of
the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part
51. Copies may be obtained from Global Engineering Documents, 15
Inverness Way East, Englewood, CO 80112, Telephone (800) 854-7179 or
Global Engineering Documents, 7730 Carondelet Ave., Suite 470, Clayton,
MO 63105, Telephone (800) 854-7179. Copies may be inspected at the
Consumer Product Safety Commission, Office of the Secretary, 4330 East
West Highway, Bethesda, Maryland or at the Office of the Federal
Register, 800 North Capitol Street, NW., suite 700, Washington, D.C.
(e) Resistance to impact test. (1) An external entrapment protection
device employing a polymeric or elastomeric material as a functional
part shall be subjected to the impact test specified in paragraph (e)(2)
of this section. As a result of the test:
(i) There shall be no cracking or breaking of the part, and
(ii) The part shall operate as intended or, if dislodged after the
test, is capable of being restored to its original condition.
[[Page 329]]
(2) Samples of the external entrapment protection device are to be
subjected to the Impact Test described in the Standard for Polymeric
Materials--Use in Electrical Equipment Evaluations, UL 746C, 4th ed.,
dated December 27, 1995, as incorporated by reference in paragraph (d)
of this section. The external entrapment protection device is to be
subjected to 5 foot-pound (6.8 J) impacts. Three samples are to be
tested, each sample being subjected to three impacts at different
points.
(3) Each of three additional samples of a device exposed to outdoor
weather when the door is the closed position are to be cooled to a
temperature of minus 31.03.6 F
(minus 35.02.0 C) and maintained at
this temperature for 3 hours. Three samples of a device employed inside
the garage are to be cooled to a temperature of 32.0 F
(0.0 C) and maintained at this temperature for 3 hours.
While the sample is still cold, the samples are to be subjected to the
impact test described in paragraph (e)(1) of this section.
