Each member body interested in a subject for which a technical committee has been non-governmental, in liaison with isO, also take part in the work. IsO collaborates closely with the International Electrotechnical Commission (IEC)on all matters of electrotechnical standardization. adopted by the technical committees are circulated to the member bodies for voting.

It defines rules for the construction of device drivers and their behaviour in the contextofanautomation and/or measurement application. The main goal of ISO 20242 is to provide users with: .independence from the computer operating system; .independence from device suppliers; . the ability to certify device drivers with connected devices and their behaviour in the context of a given computer platform; . independence from the technological device development in the future. IsO 20242 will not involve
