The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technic

International organizations, governmental and 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 el

28、 a series of International Standards relating to recreational diving services, which have been prepared with the aim of establishing a set of specifications for safety practices and the provision of services.These International Standards specify: necessary levels of experience and competency of scub
29、a divers and scuba instructors; safety practices and requirements for recreational scuba diving service providers appropriate to the different diving levels.The requirements specified are minimal; they do not preclude the provision of additional training or the evaluation of additional competencies
30、by a service provider. These International Standards represent a tool for comparison of existing (or future) qualifications of scuba divers. They do not represent a course programme, nor do they imply that course programmes and scuba diver qualifications issued by different nations or training organ
31、izations are required to correspond to these levels.

44、 in accordance with Clause 10 they are deemed to have sufficient knowledge, skill and experience to dive with other scuba divers of at least the same level in open water without supervision of a scuba instructor.Scuba divers at level 2 are qualified to dive within the following parameters unless the
45、y have additional training or are accompanied by a dive leader: dive to a recommended maximum depth of 20 m with other scuba divers of the same level; make dives, which do not require in-water decompression stops; dive only when appropriate support (e.g. first aid kit, a dive leader, support vessel;
46、 as appropriate to the dive site and the divers experience) is available at the surface; dive under conditions that are equal or better than the conditions where they were trained.If diving conditions are significantly different from those previously experienced, a scuba diver at level 2 requires an
47、 appropriate orientation from a dive leader.2 ISO 2014 All rights reservedBS EN ISO 24801-2:2014ISO 24801-2:2014(E)Where further instruction is required this may only be provided by a suitably qualified scuba instructor of level 2.
