Paragraph 2 I1

providers of Part 3 services must be able to understand which provisions of the code of practice apply in relation to a particular service they provide;

the measures described in the code of practice must be sufficiently clear, and at a sufficiently detailed level, that providers understand what those measures entail in practice;

the measures described in the code of practice must be proportionate and technically feasible: measures that are proportionate or technically feasible for providers of a certain size or capacity, or for services of a certain kind or size, may not be proportionate or technically feasible for providers of a different size or capacity or for services of a different kind or size;

the measures described in the code of practice that apply in relation to Part 3 services of various kinds and sizes must be proportionate to OFCOM’s assessment (under section 98) of the risk of harm presented by services of that kind or size.
