The ITC says that although the new code is longer, it will be simpler to use although it does not include any major new rules.
It has made the revision because a growing number of smaller television channels are vetting their own advertising, rather than running it by the Broadcast Advertising Clearance Centre, which pre-vets ads for broadcasters.
The new code will also see restrictions lifted on advertising hair-loss clinics and pregnancy testing services, although both will still be subject to relevant rules governing the advertising of health services.
However, the code on advertising gambling has not been changed, with the ITC saying it will be up to the Gambling Commission, the body being set up by the government, to make advertising rules for the sector.
Sarah Thane, director of programmes and advertising at the ITC, said: "Our aim has been to seek views on the current rules and to incorporate best practice and recent developments into the code."
She added: "The basic policies remain very much as they were and as our research indicates viewers want them to be, but we have sought to put them into a more user-friendly format."
The new code comes into effect on Monday September 2. The ITC will offer industry seminars later this year to answer questions relating to the code and revisions.
