15、ization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing 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

16、be represented on that committee. 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 electrotechnical standardization. International Stand

17、ards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. 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 ca

22、-943012002:1)E( ISO 2002 r llAithgs reservde v Introduction This part of ISO 10349 and subsequent parts deal with photographic-grade chemicals and their test methods which are cited in other International Standards for photographic-grade chemicals. Although the ultimate criterion for suitability of

23、a photographic-grade chemical is its successful performance in an appropriate use test, the shorter, more economical test methods described in subsequent parts of ISO 10349, used with those tests included in the specific chemical standards, are generally adequate. Over the past few years, great impr

24、ovements have been made in instrumentation for various analyses. Where such techniques have equivalent or greater precision, they may be used in place of the tests described in the appropriate part of ISO 10349 or in the International Standards for photographic-grade chemicals. Correlation of such a

25、lternative procedures with the given method is the responsibility of the user. Although ISO 10349 is intended for use by individuals with a knowledge of analytical techniques, this may not always be the case. Care has been taken to provide warnings for particularly hazardous materials. General hazar

26、d warnings for chemicals used in ISO 10349 and other associated International Standards are given in the text as a symbol code as a reminder in those steps detailing handling operations. More detailed information regarding hazards, handling and use of these chemicals may be available from the manufa

27、cturer. An index of the most current version of the International Standards dealing with photographic-grade chemicals and test methods is given in annex A. This annex will be updated on a regular basis upon the issue of any revision or addition to ISO 10349 or the chemical specification standards. B

36、l analysis Part 3: Specifications Second series 3 Term and definition For the purposes of this part of ISO 10349, the following term and definition apply. 3.1 photographic-grade chemicals chemicals commonly used in processing sensitized photographic materials, and more particularly those for which t

37、he quality level is so specified as not to affect the fundamental performance of the photographic material 4 Safety and operational precautions 4.1 Hazard warnings Some of the chemicals specified in the test procedures given in subsequent parts of ISO 10349 are caustic, toxic, or otherwise hazardous

38、. Safe laboratory practice for the handling of chemicals requires the use of safety glasses or goggles and, in some cases, other protective apparel such as rubber gloves, face masks and aprons. Specific danger notices are given in the test and footnotes for particularly dangerous materials, but norm

39、al precautions are required during the performance of any chemical procedure at all times. The first time that a hazardous material is noted in the test procedures, the hazard will be indicated by the word “DANGER” followed by a symbol consisting of angle brackets “ ” containing a letter which desig

40、nates the specific hazard. A double bracket “ ” will be used for particularly perilous situations. In subsequent statements involving handling of these hazardous materials, only the hazard symbol consisting of the brackets and letter(s) will be displayed. Furthermore, for a given material, the hazar

41、d symbol will be used only once in a single paragraph. Hazard warning symbols will not be used for common organic solvents when used in quantities of less than 1 litre, unless they are particularly hazardous. Detailed warnings for handling chemicals and their diluted solutions are beyond the scope o

42、f this part of ISO 10349. Employers shall provide training and health and safety information in conformance with legal requirements. The hazard code system used in this part of ISO 10349 is intended to provide information to the users and is not meant for compliance with any legal requirements for l

43、abelling, as these vary from country to country. It is strongly recommended that anyone using these chemicals obtain pertinent information from the manufacturer about the hazards, handling, use and disposal of these chemicals. 4.2 Hazard information code system B Harmful if inhaled. Avoid breathing

44、dust, vapour, mist or gas. Use only with adequate ventilation. C Harmful if contact occurs. Avoid contact with eyes, skin, or clothing. Wash thoroughly after handling. F Will burn. Keep away from heat, sparks and open flame. Use with adequate ventilation. O Oxidizer. Contact with other material may

45、cause fire. Do not store near combustible materials. S Harmful if swallowed. Wash thoroughly after handling. If swallowed, obtain medical attention immediately. S May be fatal if swallowed. If swallowed, obtain medical attention immediately. BSISO103491:20022OSI -943012002:1)E( ISO 2002 r llAithgs r
