6、es intended to be mounted on the inside of the protected area. Security latches covered bythis outline do not have any exposed parts on the exterior side of the door.1.2 A security latch shall provide a degree of protection against:a) Static strength rating of 1500 pounds-force (6673 N). See 9.2.1.b

7、) Dynamic strength rating of 70 foot-pounds-force (95 J). See 9.3.1.2 Components2.1 Except as indicated in 2.2, a component of a product covered by this Outline of Investigation shallcomply with the requirements for that component.2.2 A component is not required to comply with a specific requirement

8、 that:a) Involves a feature or characteristic not required in the application of the component in theproduct covered by this Outline of Investigation; orb) Is superseded by a requirement in this Outline of Investigation.2.3 A component shall be used in accordance with its rating established for the

9、intended conditions ofuse.2.4 Specific components are incomplete in construction features or restricted in performance capabilities.Such components are intended for use only under limited conditions, such as certain temperatures notexceeding specified limits, and shall be used only under those speci

10、fic conditions.3 Units of Measurement3.1 Values stated without parentheses are the requirement.

12、any each product orcomponent is to be furnished with the sample submitted for investigation to be used as a guide in theexamination and test of the product or component. For this purpose, a final printed edition is not required.5.2 The instructions and drawings shall include at least the following:a

13、) Typical installation drawing layouts for the product indicating recommended locations whereinstallations are not recommended shall also be included.b) Concise description of the operation.c) Identification of replacement parts, by a part number, manufacturers model number, or othermeans that have

14、been determined to be equivalent.d) A description of any features provided to reduce the risk injury to persons and a warningagainst bypassing such features as applicable.5.3 The instructions may be incorporated on the inside of the product, on a separate sheet, or as part ofa manual. When not inclu

15、ded directly on the product, the instructions or manual shall be referenced in themarking information on the product.CONSTRUCTION6 Design Features6.1 Security features of a latch assembly shall be designed such that they do not result in the opening ofthe door.

17、ition to the following tests from the Standard for AntitheftAlarms and Devices, UL 1037: Section 26 Normal Operation Test, Section 38 Endurance Test,Section 39 Jarring Test, and Section 40 Road Shock and Vibration Tests, unless otherwise specified.8 Test Fixture8.1 A security latch device intended t

18、o be used in an ordinary door is to be mounted in the test fixturedescribed in 8.2 for all tests.8.2 The door used to test a security latch device intended for use in an ordinary door shall be solid wood,1-1/2 to 1-3/4 inches (38 to 44 mm) thick by 36 inches (0.91 m) wide and 72 to 84 inches (1.8 to

19、 2.1 m)high. The door is to be mounted in a sheet steel frame, which is mounted into a masonry wall or in aridged steel frame secured to the floor and braced on the side that would be the inside of the door. Thedoor is to be hung on three heavy-duty, five-knuckle, ball-bearing hinges.Exception: A se

20、curity latch device intended for use on a door or opening cover that differs from the testdoor described in this requirement is to be tested on the door that it is constructed for or on a test fixturerepresentative of the door as indicated in the installation instructions for the product.9 Forcing T

21、ests9.1 Static and dynamic strength tests9.1.1 When installed as intended in the test fixture described in Section 8, a security latch device is to besubjected to a static strength test followed by a dynamic strength test.9.1.2 The static and dynamic strength tests are to be conducted with the force

22、 or impact applied at a point40 inches (1 m) above the bottom edge of the door and 6 inches (152 mm) in from the unhinged edge.9.2 Static strength test9.2.1 With the security latch device in the locked condition, force is to be applied at the point specified in9.1.2 at a rate not slower than 10 poun

23、ds-force (44 N) nor faster than 20 pounds-force (90 N), per seconduntil the static strength is reached and is held for 1 minute. The rated static strength shall be 1500pounds-force (6673 N), as specified in 1.2. The force is to be measured at the point where the force isapplied.AUGUST 31, 2012UL 103

The dynamic strength shall be

25、70 foot-pounds-force (95 J), as specified in1.2.9.3.2 The ram used to apply the impact in the dynamic strength test is to be a solid steel cylinder, 60.008 inches (152 0.2 mm) in diameter and 13-1/4 inches (336 mm) long overall, with a rounded impactnose. The length of the ram is to consist of a mai

26、n portion measuring 11 0.11 inches (279 2.8 mm) withthe cone portion measuring 2.25 0.008 inches (57 0.2 mm). The total weight of the ram is to equal 100pounds (45.5 kg). See Figure 9.1.This is generated text for figtxt.9.3.3 The ram is to be suspended from four steel cables, with two attached to th

27、e front and two to therear of the ram. The cables are to be attached to a fixed overhead beam or the equivalent, 5.5 to 6 feet(1.7 to 1.8 m) above the center line of the ram. The two front and two rear cables are to be parallel toeach other and are to be 23 to 25 inches (58 to 63 cm) apart where the

28、y are attached to the beam. Whenthe ram is drawn back to deliver the impact, it is to remain level.

31、05 Nm) torque 150 pounds by 1.5 feet (667 N by 0.46 m) is to be applied tothe handle in the direction used for normal operation while the product is in the secure condition. Thetorque is to be applied gradually until the 225 pound-foot torque is reached and is to be held for 1 minute.9.4.3 The door
