Engineering Standards Lab

IEC 60083 Type A-O millimeter pin dimensions, appliance couplers C1-C20, and industrial plugs.

VoltTrip Standards Lab Mission Manifesto:

Following the official retirement of the IEC World Plugs tool, international travelers and electrical engineers lacked a unified, transparent authority. VoltTrip provides open-access, millimeter-accurate electrical specifications, laboratory-tested hardware benchmarks, and unbiased multi-merchant price intelligence to eliminate electrical fires and damaged electronics worldwide.
