The work of prepa
11、ring International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in l
12、iaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task o
13、f technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention i

17、cope This International Standard specifies the level of competence required of a scuba diver in order to be awarded an enriched air nitrox (EAN) diver certification by a training organization. This International Standard also specifies the conditions under which training is to be provided, which sup
18、plement the general requirements for recreational diving services specified in ISO 24803. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition

24、gases at levels no higher than those found in normal air 4 Competences of a certified enriched air nitrox diver The training programme shall ensure that, when assessed in accordance with Clause 10, scuba divers are qualified to plan, conduct and log EAN open-water, no-decompression dives, when accom
25、panied by another scuba diver of at least level 2 “Autonomous diver”, in accordance with ISO 24801-2; procure EAN mixes, EAN equipment and other services to engage in recreational EAN diving without supervision. The training programme does not qualify divers to make dives which require mandatory in-
26、water decompression stops or dives using more than one breathing gas and/or rebreathers. Such dives are beyond the scope of this International Standard and require additional training. 5 Prerequisites for training 5.1 Minors Documented parental or legal guardian consent shall be obtained when the ap
27、plicant is a minor. 5.2 Health requirements If training dives are to be conducted as part of the training programme, documented evidence shall be obtained that the student has been medically screened as suitable for recreational diving, by means of an appropriate questionnaire or medical examination
28、. In case of doubt, or at the scuba instructors discretion, students shall be referred to proper medical resources. If the student is not examined by a physician, the student shall be obliged to confirm by signature that he or she has understood written information given by the scuba instructor on d
29、iseases and physical conditions which may pose risks in relation to diving. Students shall be advised of the importance of appropriate regular medical examinations. 6 Required theoretical knowledge 6.1 Equipment The training programme shall ensure that students have appropriate knowledge of the phys
30、ical characteristics, operating principles, maintenance requirements and use of EAN diving equipment. This shall include at least the following: how EAN use impact diving equipment (e.g. increased oxidation and wear); the suitability of scuba equipment for use with EAN, including national and/or reg
31、ional regulations; BS ISO 11107:2009ISO 11107:2009(E) ISO 2009 All rights reserved 3 the suitability of scuba cylinders for EAN (e.g. when oxygen service may be required); EAN cylinder markings. The students should be made aware of the importance of following the recommendations of equipment manufac
32、turers regarding the use of their equipment with EAN. 6.2 Physics of diving with EAN The training programme shall ensure that students have appropriate knowledge of the physical principles of EAN and its application to diving activities. This shall include at least the following: what EAN is; partia
33、l pressures; the benefits of reduced exposure to nitrogen on decompression, e.g. equivalent air depth (EAD); EAN use and bottom time. 6.3 EAN handling risks The training programme shall ensure that students have appropriate knowledge of risks related to the handling of EAN mixtures with elevated oxy
34、gen levels. This shall include at least knowledge about factors likely to increase the risk of fire or explosion. 6.4 Medical issues The training programme shall ensure that students have appropriate knowledge of the causes, symptoms, prevention, first-aid and proper handling of EAN-related diving m
35、edical problems. This shall include at least the following: EAN and narcosis; oxygen toxicity; decompression illness. Instructions shall include why buddy teams must plan their dive in accordance with: the limits of the diver with the most conservative maximum operating depth, no decompression limit
36、, or oxygen toxicity limit. 6.5 Use of dive tables and dive computers The training programme shall ensure that students have an appropriate knowledge of using dive tables, dive computers and/or dive planning software, including: how to determine oxygen partial pressure (PO2); managing exposure to ni
37、trogen, e.g. by using the equivalent air depth concept; how to determine the maximum operating depth for a particular EAN mixture, taking into consideration its oxygen content; how to use EAN dive tables and/or a EAN-programmable dive computer to plan and execute single and repetitive dives. BS ISO
38、11107:2009ISO 11107:2009(E) 4 ISO 2009 All rights reserved7 Practical skills The training programme shall ensure that students are able to perform the following practical skills: how to use an oxygen analyzer to determine the oxygen content in an EAN blend; how to fill out cylinder content tags/stic
39、kers; how to complete and sign a filling stations EAN fill log, including maximum operating depth and oxygen content. 8 Practical training parameters If the training programme includes open water dives using EAN as a breathing gas, the maximum PO2 shall not exceed 160 kPa (1,6 bar). 9 Scuba instruct
40、ors Scuba instructors teaching the training programme and assessing students in accordance with this International Standard shall have completed formal training for EAN training programmes. 10 Certification The training programme may be conducted in conjunction with scuba diver training in accordanc
41、e with ISO 24801-2, but the certification shall not be issued until such time as the student has finalized all certification requirements in accordance with ISO 24801-2. The student shall demonstrate EAN knowledge to a scuba instructor by taking and passing an oral or written examination. This exami
42、nation shall test EAN knowledge in accordance with Clause 6. The scuba instructor shall ensure that the student has the ability to analyze EAN and plan dives using EAN, prior to certification in accordance with Clause 7. NOTE Open water dives using EAN are not a requirement in order to complete the
43、training programme in accordance with this International Standard, but they are encouraged.
