Similar International Standards
IEC 60884-1:2022IEC (International)
HighCurrent
Plugs and socket-outlets for household and similar purposes - Part 1: General requirements
Base international standard for general safety requirements and tests, on which IS 1293:2019 is based.
BS 546:1950+A3:2012BSI (UK)
HighCurrent
Two-pole and earthing-pin plugs, socket-outlets and socket-outlet adaptors
Defines the original dimensional standard for Type D and M plugs, from which the Indian system is directly derived.
SANS 164-1:2015SABS (South Africa)
HighCurrent
Plug and socket-outlet systems for household and similar purposes for use in South Africa - Part 1: Conventional systems
Specifies the Type M plug system (16 A), which is dimensionally identical to the Indian 16 A plug.
BS 1363-1:2016+A1:2018BSI (UK)
MediumCurrent
13 A plugs, socket-outlets, adaptors and connection units. Specification for rewirable and non-rewirable 13 A fused plugs
Covers household plugs/sockets with similar safety principles, but for a different system (Type G, fused plugs).
Key Differences
≠IS 1293 is a complete standard that specifies both general requirements and the dimensional standard sheets for Indian plugs and sockets (Types D and M). In contrast, IEC 60884-1 is a general requirements standard only and must be used with a country-specific Part 2 standard sheet that defines the plug/socket dimensions.
≠IS 1293:2019 makes protective shutters mandatory for all socket-outlets to prevent accidental contact with live parts. The base international standard, IEC 60884-1, treats shutters as an optional safety feature, leaving the decision to national committees.
≠A key national deviation in IS 1293 is the maximum permissible temperature rise for terminals, which is set at 50 K. The corresponding limit in IEC 60884-1 (2013 edition) is stricter, at 45 K.
≠IS 1293 specifies mandatory certification and marking with the Bureau of Indian Standards (BIS) Standard Mark (ISI Mark) for products sold in India. IEC 60884-1 defines general marking requirements but does not and cannot mandate a specific national certification mark.
Key Similarities
≈IS 1293:2019 is technically harmonized with IEC 60884-1:2013, adopting its structure, clause numbering, and definitions. This makes cross-referencing between the two standards straightforward.
≈Both standards are founded on identical fundamental safety principles, focusing on protection against electric shock, ensuring adequate thermal performance during use, preventing fire hazards, and guaranteeing mechanical strength and durability.
≈The majority of test procedures are directly adopted from the IEC standard. Key tests for safety and performance, such as the normal operation (endurance) test, withdrawal force measurement, insulation resistance, and dielectric strength tests, are identical in methodology.
≈Requirements for materials, particularly those concerning resistance to heat, fire, and tracking for insulating components, are harmonized. Both standards specify the same tests, such as the Glow-wire test (at 850°C for parts retaining live contacts) and the Ball Pressure test (at 125°C).
