10 Blade Strength Test
10.1 General
10.1.1 The blades of a receptacle closure shall withstand the application of the test forces described in
10.2, 10.3 and 10.4 without cracking or breakage. Permanent deflection of the closure blade or face upon completion of the testing meets the intent of this requirement.
10.2 Vertical blade orientation
10.2.1 Six receptacle closures are to be subjected to this test. Three closures are to be tested as received and three tested after being subjected to the Mold Stress Relief Test, Section 9. Each closure in turn is to be supported with its face fixed in a horizontal plane and its blades projecting downward in a vertical orientation as shown in Figure 10.1. A weight that exerts a force of 20 Ibf (89 N) is to be suspended from each blade in succession. The pull is to be gradually applied and held for one minute.
10.2.1 revised July 31, 2012
10.3 Horizontal blade orientation, flat of blade
10.3.1 Six receptacle closures are to be subjected to this test. Three closures are to be tested as received and three tested after being subjected to the Mold Stress Relief Test, Section 9. Each closure in turn is to be supported with its face fixed in a vertical plane and its blades projecting horizontally with the flat surface of the blade parallel to the ground as shown in Figure 10.1. A force of 20 lbf (89 N) is to be exerted on the flat surface of each blade in succession, within 3/16 inch (1 .9 mm) of the tip of the blade. The force is to be gradually applied and held for one minute.
11 Details
11 .1 A receptacle closure shall be legibly and permanently marked, where readily visible, with the manufacturer’s name, trade name, trademark or other descriptive marking by which the organization responsible for the device shall be identified. The manufacturer’s identification shall not be in a traceable code unless the device is identified by the brand or trademark owned by a private labeler.
11.2 If a manufacturer produces receptacle closures at more than one factory, each closure shall have a distinctive marking on the device, that may be in code, by which the device is able to be identified as the product of a particular factory.
11.3 The packaging of a receptacle closure shall be marked with the manufacturer’s identification as described in 11.1 and with a model number or equivalent designation.
11.4 The packaging of a receptacle closure that relies solely upon the closure blades to remain seated in a receptacle shall be marked with the following statement or an equivalent wording after the word “WARNING”: “WARNING: RISK OF FIRE OR ELECTRIC SHOCK. If the closure falls out of or fits loosely in the receptacle, the receptacle contacts may be worn or broken. To reduce the risk of fire or injury caused by overheating, arcing or exposure of live plug blades, do not use the receptacle until it has been examined by a licensed electrician to determine whether the outlet needs to be replaced.”
11.5 The packaging of a receptacle closure intended to restrict a child’s access to energized receptacle contacts shall be marked with the following statement or an equivalent wording after the word “WARNING”: “WARNING: RISK OF ELECTRIC SHOCK. This device is intended to make it difficult for children to gain access to energized outlets. Like any other child-resistant product, this device is not a substitute for adult supervision. An unsupervised child may be able to defeat this product. As with all electrical products, precautions should be observed during handling and use to prevent electric shock. Discourage children from playing with electrical equipment.”
11.6 The packaging of a receptacle closure that is intended to reduce drafts through a receptacle on an outside wall of a dwelling and that is not intended to restrict a child’s access to energized contacts shall be marked to describe its intended use and indicate that it is not intended to prevent a child from contacting energized receptacle contacts.
