Argentina IRAM 2073 & 2071 (Argentinian 10 A/250 V) and compatible types (Type I)
The plug and socket used in Class 1 applications in Argentina is defined by IRAM. The applicable standards are: IRAM 2073 “Grounded bipolar plugs for residential use, 10 A and 20 A, 250 V AC” and IRAM 2071 “Grounded bipolar outlets for residential use, 10 A and 20 A, 250 V AC” It is similar in appearance to the Australasian and Chinese plugs. The pin length is same as the Chinese version. The most important difference from the Australian plug is that the Argentinian plug is wired with the line and neutral contacts reversed.
In Brazil, this kind of plug is still commonly found in high-power appliances like air conditioners, dishwashers, and household ovens. Since the adopted IEC 60906-1 standard prescribes a high-current plug version, the original motivation to use the “Argentinian” plug has ceased to exist.
Australian standard AS/NZS 3112 (Australasian 10 A/240 V)(Type I)

Australasian switched 3-pin dual power point (socket)
The plug used in Australia, New Zealand, Fiji, Tonga, Argentina, Solomon Islands, Papua New Guinea and China has an earthing pin and two flat current-carrying pins forming an upside down V-shape.The flat blades measure 6.5 by 1.6 mm (0.256 by 0.063 in) and are set at 30° to the vertical at a nominal pitch of 13.7 mm (0.539 in). Australian and New Zealand wall sockets almost always have switches on them for extra safety, as in the UK. An unearthed version of this plug with two angled power pins but no earthing pin is used with small double-insulated appliances, but the sockets always include an earth pin.
There are several AS/NZS 3112 plug variants, including ones with larger or differently shaped pins used for devices drawing 15, 20, 25 and 32 A. These sockets accept plugs of equal or of a lower current capacity, but not of higher capacity. For example, a 10 A plug will fit all sockets but a 20 A plug will fit only 20, 25 and 32 A sockets.
Australia’s standard plug/socket system was originally codified as standard C112 (floated provisionally in 1937, and adopted as a formal standard in 1938), which was superseded by AS 3112 in 1990. The requirement for insulated pins was introduced in the 2004 revision.The current version is AS/NZS 3112:2011, Approval and test specification – Plugs and socket-outlets.
