This International Standard specifies minimum requirements for training organizations that offer introductory scuba experience training programmes to non-divers. This International Standard applies to programmes that include participants being taken into an open water environment. It does not apply to programmes that are exclusively conducted in a confined water environment (e.g. swimming pools). This International Standard also specifies the conditions under which this service is to be provided, which supplement the general requirements for recreational diving services specified in ISO 24803.
