Three-Pin Test Plug for Checking Three-Pin Flat-Pin 250 V Max. Socket-Outlets Against The Standard Test Finger with AS/NZS 3112 Figure C1
PREVENTION OF CONTACT WITH LIVE PINS
NOTE: Fully recessed socket-outlets that comply with Clause 3.6.4 are deemed to comply with Clauses 3.8.1 and 3.8.2.
During normal insertion
At any stage during normal insertion of a non-insulated pin plug into a socket-outlet, with the faces of the plug and socket-outlet in parallel planes, it shall not be possible to touch, with the standard test finger (see AS/NZS 3100), a pin that may become alive.
Socket-outlets, for use with two-pin flat-in plugs of the type shown in Figure 2.1(b), shall be checked for conformance with this requirement by means of an appropriate test plug having the minimum diameter of face and maximum length of live pins shown in
Figure 2(b).
Socket-outlets for use with three-pin flat pin plugs of the type shown in Figure 2.1(a) and Figure 2.1(d), and two-pin flat pin plugs of the type shown in Figure 2.1(c) and Figure 2.1(d), shall be checked for conformance with this requirement by means of an appropriate test plug having the dimensions shown in Figure C1 of Appendix C.
Three-Pin Test Plug for Checking Three-Pin Flat-Pin 250 V Max. Socket-Outlets Against The Standard Test Finger with AS/NZS 3112 Figure C1
Socket-outlets for use with three-pin plugs of the type having two flat live pins and one round earth pin, or two round live pins and one flat earth pin, as shown in Figure 2.1(f) and Figure 2.1(g), shall be checked for conformance with this requirement by means of the appropriate test plug having the dimensions shown in Figure G1(a) or Figure G1(b) of Appendix G, respectively.
For socket-outlets with covers that are intended to be removed for interchangeability, this test shall be conducted with and without the cover in position.
During other than normal insertion
The design and construction of a socket-outlet shall be such that it is not possible for any pin of a plug with which the socket-outlet may appropriately be used to touch a live contact except during normal insertion, i.e. with each pin entering or adjacent to the aperture for the appropriate contact.
Socket-outlets for use with two-pin flat pin plugs of the type shown in Figure 2.1(b) shall be checked for conformance with this requirement by means of an appropriate test plug having the minimum diameter of face and maximum length of live pins shown in Figure 2.1(b).
Socket-outlets for use with three-pin flat pin plugs of the type shown in Figure 2.1(a) and Figure 2.1(d), and two-pin flat pin plugs of the type shown in Figure 2.1(c) and Figure 2.1(d), shall be checked for conformance with this requirement by means of an appropriate test plug having the dimensions shown in Appendix D.
NOTE: This provision is intended to prevent the insertion of one pin of a plug while the other pin or pins are overhanging the socket-outlet, and to prevent the insertion of an earthing pin in a live contact.
For socket-outlets with covers that are intended to be removed for interchangeability, this test shall be conducted with and without the cover in position.
Alignment of faceplates
The socket-outlet shall incorporate positive means to preclude incorrect assembly and to ensure that the plug pin apertures in the socket-outlet faceplate will always be aligned with the appropriate contacts of the socket-outlet.

The ipx9k High Temperature Pressure Jet Waterproof Test Chamber is characterized by a waterproof grade of 9, indicating high temperature and high pressure water spraying, and spraying high temperature and high pressure water in various directions of the shell for water spraying test. In addition, k represents a function of pressurization, and under such strict conditions, its water pressure will become stronger. The ipx9 is currently a high level of waterproof protection. The IPx9 High Temperature Pressure Jet Waterproof Test Chamber is also widely used in fields such as LED lighting fixtures, display screens, household appliances industry, automobiles, and automotive accessories. At the same time, all dust and waterproof equipment can be customized according to user needs. The ipx9k High Temperature Pressure Jet Waterproof Test Chamber has four different vertical spray angles, namely 0 °, 30 °, 60 °, and 90 °, and the water pressure can reach 8000 to 10000 Kpa; Moreover, its testing r

Capacitance  refers to the ability to hold a charge. It is a medium for realizing the storage and release of static charges, with the characteristic of permanent charge storage. Capacitor components are widely used in power supply filtering, signal filtering, signal coupling, resonance, filtering, compensation, charging and discharging, energy storage, and power separation in circuits. According to its ability to accommodate charges, it is generally measured in Farads, and the international unit is Farads. Therefore, capacitors are essential components for electronics and power. The role of capacitors: Bypass capacitors and decoupling capacitors are two devices that provide energy storage for local devices. Bypass capacitors can reduce load demand, make the output of the voltage regulator smooth, similar to a small rechargeable battery, and can be discharged and charged. The decoupling capacitor can smooth the edge signals of the device, so as to prevent the input signal from being too

1 General 1.1 Scope and object This International Standard(IEC61032) specifies details and dimensions of test probes intended to verify the protection provided by enclosures with regard to: – protection of persons against access to hazardous parts inside the enclosure; – protection of the equipment inside the enclosure against ingress of solid foreign objects. SMT IP10T_AL The object of this International Standard is: – to bring together in one publication object probes and access probes currently specified in other standards, together with any necessary new probes;    – to guide technical committees in the selection of test sphere; – to encourage those concemed to specify test probes in accordance with those already specified in this International Standard rather than modify details and dimensions; – to limit the further proliferation of types of test probe. 1.2 General recommendations When selecting probes, priority should be given to IP code probes. The use of other probes, particul
