Test Gauge with UL498 Figure 111.1
Retention of Blades Test
A flush or self-contained receptacle having a 5-15R,5-20R,6-15R, or 6-20R configuration shall be subjected to the retention of blades test described in this Section.
Exception: A receptacle having a 1-15R,5-15R,5-20R,6-15R, or 6-20R configuration and not of the flush or self-contained type may instead be subjected to the Retention of Plugs Test, Section 116.
Receptacles having the break-off tab, when provided, removed from one nonidentified terminal are to be subjected to ten conditioning cycles of manual insertion and withdrawal of a standard test gauge, see Figure 111.1. Each of six devices is to be tested. The gauge is to be configured as outlined in Table 111.1. The force applied to insert the gauge for any of the conditioning cycles is not to exceed 40 lbf (178 N). The gauge is to have the dimensions indicated in Figure 111.1 but is not to have holes in the outer ends of the blades.
Test Gauge with UL498 Figure 111.1
The standard test gauge is to be configured as shown in Table 111.2 using the line blades without holes and with the grounding blade removed. The gauge is then to be inserted in the receptacle and a static 3 lbf (13.3 N) (including the weight of the gauge), which tends to remove the gauge from the receptacle, is to be applied for a period of 1 minute in a direction normal to the plane of the face of the receptacle. There shall not be more than 0.079 inch (2 mm) displacement of the gauge.
The standard gauge is to be configured as shown in Table 111.3 using the line blades with holes in the end and with the grounding blade in place. The test is to be conducted using the apparatus as described in Figure111.1A. The test gauge is attached to the apparatus as shown. The apparatus consists of a principal mass, and a supplementary mass. The supplementary mass is 1.5 lbs (6.7 N). The principal mass, together with the supplementary mass, the Gage and any hardware equals 15 lbs (67 N) total. The gage is inserted fully into the device.
The principal mass and associated hardware is hung on the gage without jolting. The gage shall not remain in the receptacle. If the gage does not withdraw the supplementary mass is raised and allowed to fall from a height of 2 in (51 mm) onto the principal mass one time. The gage shall not remain in the receptacle. A test apparatus that does not incorporate a supplementary mass and equals the 15 lbs (67 N) total is permitted if agreeable to all parties.

What are the differences of FMVSS 302, UL94 and IEC60695 for flammability test?

Image
The flammability of different materials, such as plastics and other materials used in items such as automobile interiors, electronic devices, and electrical appliances, is evaluated using a number of different standards. Some of these standards are FMVSS 302, UL 94, and IEC 60695. Nevertheless, there are a number of important distinctions between these standards: FMVSS 302 is a specialized standard that was designed for the automotive industry to analyze the flammability of materials used in car interiors. Its purpose is to measure the combustibility of these materials. The UL 94 standard is a more comprehensive regulation that assesses the combustibility of a variety of materials, including plastics, and has applications in a number of different sectors. IEC 60695 is a global standard that is used in the process of assessing the potential for electronic and electrical equipment to catch fire. Testing Procedures The flammability of materials is determined using a variety of testing ...

125 Grounding Contact Test 125.1 Grounding receptacles having a 5-15R,5-20R，6-13R，6-20R，7-15R，14-15Ror 15-15R configuration are to be subjected to the tests in this section. 125.2 Previously untested devices are to be used. Each device is to be mounted in a flush device box, or as otherwise intended, with its face in a vertical plane. A nonmetallic faceplate is to be installed if intended. A solid 14 AWG (2.1 mm2) copper conductor is to be connected to the receptacle grounding terminal. GNGPL SB1610_AL 125.3 With the receptacle oriented to create the maximum contact displacement (possible distortion of contact affecting its contact ability), the test pin A. Figure 125.1 is to be fully inserted in the grounding contact. A 5 lb (2.27 kg) weight is to be gradually suspended form the test pin 6 inches (152 mm) from the face of the receptacle. The weight is to be applied for 1 minute, following which, the weight is to be removed. The application of the weight is to be repeated with the rece...

Accessible parts of equipment with standard IEC 62368 General An accessible part of an equipment is a part that can be touched by a body part. For the purposes of dctermining an accessible part, a body part is represented by one or more of the specified test probes. Accessible parts of an equipment can include parts behind a door, panel, removable cover, etc. that can be opened without the use of a tool. Accessible parts do not include those that become accessible when floor standing equipment having a mass exceeding 40 kg is tilted. For equipment intended for building-in or rack-mounting, or for subassemblies and the like for incorporation in larger equipment,accessible parts do not include those that are not accessible when the equipment or subassembly is installed according to the method of mounting or installation specified in the installation instructions. A part is considered accessible if the instructions or markings intended to be followed require that a person phys...
