# §1211.5. General testing parameters.

- (a) The following test parameters are to be used in the investigation of the circuit covered by [§ 1211.4(c)](/cfr/16/1211.4.md?p=c) for compliance with either, UL 991, or Supplement SA of UL 325-2017 (incorporated by reference, see [§ 1211.40](/cfr/16/1211.40.md)):
  - (1) With regard to electrical supervision of critical components, an operator being inoperative with respect to closing 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 °Celsius (minus 31 °F) and 70 °C (158 °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, λp shall not be greater than 6 failures/10 6 hours for the entire system. For external secondary entrapment protection devices or systems that are sold separately, λp shall not be greater than 0 failures/10 6 hours. For internal secondary entrapment protection devices or systems whether or not they are sold separately, λp shall not be greater than 0 failures/10 6 hours. The operational test is conducted for 14 days. An external secondary entrapment protection device or system that is sold separately, and that has a λp 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 or system λp does not exceed 6 failures/10 6 hours. See [§ 1211.18(j) through (l)](/cfr/16/1211.18.md?p=j..l).
  - (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 °C (140 °F), or 10 °C (18 °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 to [subpart A](/cfr/16/subpartA.md) shall be used:
  - (1) To conduct a failure-mode and effect analysis (FMEA);
  - (2) In investigating the performance during the Environmental Stress Tests;
  - (3) During the Power Cycling Safety for Tests in accordance with UL 991 (incorporated by reference, see [§ 1211.40](/cfr/16/1211.40.md)); and
  - (4) During evaluation of the circuit to the requirements of Supplement SA of UL 325-2017 (incorporated by reference, see [§ 1211.40](/cfr/16/1211.40.md)).
