                     TITLE 16--COMMERCIAL PRACTICES
 
             CHAPTER II--CONSUMER PRODUCT SAFETY COMMISSION
 
PART 1211--SAFETY STANDARD FOR AUTOMATIC RESIDENTIAL GARAGE DOOR OPERATORS--Table of Contents
 
                         Subpart A--The Standard
 
Sec. 1211.5  General testing parameters.

    (a) The following test parameters are to be used in the 
investigation of the circuit covered by Sec. 1211.4(c) for compliance 
with the Standard for Safety for Tests for Safety-Related Controls 
Employing Solid-State Devices, UL 991, second edition, dated June 23, 
1995, as incorporated by reference in paragraph (b)(3) of this section:
    (1) With regard to electrical supervision of critical components, an 
operator being inoperative with respect to downward movement of the door 
meets the criteria for trouble indication.
    (2) A field strength of 3 volts per meter is to be used for the 
Radiated EMI Test.
    (3) The Composite Operational and Cycling Test is to be used for 14 
days at temperature extremes of minus 35  deg.Celsius (minus 31  deg.F) 
and 70  deg.C (158  deg.F).
    (4) Exposure Class H5 is to be used for the Humidity Test.
    (5) A vibration level of 5g is to be used for the Vibration Test.
    (6) When a Computational Investigation is conducted, 
[lgr]p shall not be greater than 6 failures/10\6\ hours for 
the entire system. For external secondary entrapment protection devices 
that are sold separately, [lgr]p shall not be greater than 0 
failures/10\6\ hours. For internal

[[Page 324]]

secondary entrapment protection devices whether or not they are sold 
separately, [lgr]p shall not be greater than 0 failures/10\6\ 
hours. The operational test is conducted for 14 days. An external 
secondary entrapment protection device that is sold separately, and that 
has a [lgr]p greater than 0 failures/10\6\ hours meets the 
intent of the requirement when for the combination of the operator and 
the specified external secondary entrapment protection device 
[lgr]p does not exceed 6 failures/10\6\ hours. See 
Sec. 1211.15(i) and (k).
    (7) When the Demonstrated Method Test is conducted, the multiplier 
is to be based on the continuous usage level, and a minimum of 24 units 
for a minimum of 24 hours per unit are to be tested.
    (8) The Endurance test is to be conducted concurrently with the 
Operational test. The control shall perform its intended function while 
being conditioned for fourteen days in an ambient air temperature of 60 
deg.C (140  deg.F), or 10  deg.C (18  deg.F) greater than the operating 
temperature of the control, whichever is higher. During the test, the 
control is to be operated in a manner representing the opening and 
closing of the door at a rate of one open-close operation per minute.
    (9) For the Electrical Fast Transient Burst Test, test level 3 is to 
be used for residential garage door operators.
    (b) In the evaluation of entrapment protection circuits used in 
residential garage door operators, the critical condition flow chart 
shown in figure 1 shall be used:
    (1) To conduct a failure-mode and effect analysis (FMEA);
    (2) In investigating the performance during the Environmental Stress 
Tests; and
    (3) During the Power Cycling Safety for Tests in accordance with the 
Standard for Safety for Tests for Safety-Related Controls Employing 
Solid-State Devices, UL 991, second edition, dated June 23, 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
