12、Photographic-grade chemical standards37ContentsPageiiThis part of ANSI/NAPM IT4.99 and subsequent parts deal with photo-graphic-grade chemicals and their test methods which are cited in otherstandards for photographic-grade chemicals. In the current review pro-cess, this series of standards along wi

13、th the chemical specification stan-dards are being updated and revised in format. Many of the chemicalspecification standards, but not all, also exist as standards of theInternational Organization for Standardization (ISO), and these test meth-ods standards are equivalent to ISO 10349. The current u

14、pdates and revi-sions are in accord with that being done for the ISO standards and thecommon standards are technically identical with their ISO counterparts. It has become the practice to adopt the international standards directlywhere practicable, and it was strongly desired to follow this practice

15、.However, the committee took note of the fact that the ISO conventionrequires the use of the comma, “,“, as the decimal radix whereas in theU.S. the period, “.“, is the decimal radix and that this could lead to misin-terpretations with serious consequences. The situation is further compli-cated by t

16、he fact that a large number of standards in this series do nothave ISO counterparts, and this would lead either to writing U.S. standardswith ISO conventions, or having a series of standards with the two differ-ent conventions both of which refer to these test methods which wouldhave been in the ISO

17、 convention. It was felt that neither of these was asatisfactory alternative and it was, therefore, decided to modify the formatof the ISO standards with the use of U.S. conventions. In technical con-tent, these standards are the same as their ISO counterparts. In an effortto promote the concept of

18、international standardization, references to ISOstandards have been left in place with the exception of the references tothe various parts of these test methods standards. In addition, a table ofequivalent standards is given in annex B.This standard contains two annexes. Annex A is normative and is

19、consid-ered part of this standard. Annex B is for information only.Suggestions for the improvement of this standard will be welcome. Theyshould be sent to the National Association of Photographic Manufacturers,Inc., 550 Mamaroneck Avenue, Suite 307, Harrison, NY 10528-1612.This standard was processe

26、ted in otherANSI standards for photographic-grade chemicals. Although the ultimatecriterion for suitability of a photographic-grade chemical is its successfulperformance in an appropriate use test, the shorter, more economical testmethods described in subsequent parts of ANSI/NAPM IT4.99, used witht

27、hose tests included in the specific chemical standards, are generally ade-quate.Over the past few years, great improvements have been made in instru-mentation for various analyses. Where such techniques have equivalent orgreater precision, they may be used in place of the tests described in theappro

28、priate general test method standard for photographic-grade chemi-cals or the ANSI standards for photographic-grade chemicals. Correlationof such alternate procedures with the given method is the responsibility ofthe user.Although ANSI/NAPM IT4.99 is intended for use by individuals with aworking know

29、ledge of analytical techniques, this may not always be thecase. Care has been taken to provide warnings for particularly hazardousmaterials. General hazard warnings for chemicals used in ANSI/NAPMIT4.99 and other associated ANSI standards are given in the text as asymbol code as a reminder in those

30、steps detailing handling operations.More detailed information regarding hazards, handling, and use of thesechemicals may be available from the manufacturer.An index of the most current versions of the associated ANSI and ISOstandards dealing with photographic-grade chemicals and the test meth-ods is

31、 given in annex B. This annex will be updated on a regular basis withthe issue of any revisions or additions to ANSI/NAPM IT4.99 or the chemi-cal specification standards.IntroductionAMERICAN NATIONAL STANDARD ANSI/NAPM IT4.99-1996American National Standardfor Photography Photographic-grade Chemicals

32、 Test Methods1Part 1:General1 ScopeThis part of ANSI/NAPM IT4.99 specifies criteria for reagents and materials, and addresses a num-ber of general and common aspects involved in performing the tests given in the subsequent partsof ANSI/NAPM IT4.99. Annex B provides an index of the most current versi

33、on of the parts ofANSI/NAPM IT4.99 and the associated ISO standard on photographic-grade chemical specifications.2 Normative referencesThe following standards contain provisions which, through reference in this text, constitute provisionsof ANSI/NAPM IT4.99. At the time of publication, the editions

34、indicated were valid. All standards aresubject to revision, and parties to agreements based on this part of ANSI/NAPM IT4.99 are encour-aged to investigate the possibility of applying the most recent editions of the standards indicatedbelow.

39、eriesISO 6353-3:1987, Reagents for chemical analysis Part 3: Specifications Second series3 DefinitionsFor the purposes of ANSI/NAPM IT4.99, the following definition applies.3.1 photographic-grade chemicals: Chemicals commonly used in processing sensitized photo-graphic materials, and more particular

40、ly those for which the quality level is so specified as not to af-fect the fundamental performance of the photographic material.4 Hazards4.1 Hazard warningsSome of the chemicals specified in the test procedures given in subsequent parts of ANSI/NAPMIT4.99 are caustic, toxic, or otherwise hazardous.

41、Safe laboratory practice for the handling of chemi-cals requires the use of safety glasses or goggles, rubber gloves and other protective apparel suchas face masks or aprons where appropriate. Specific danger notices are given in the text and foot-notes for particularly dangerous materials, but norm

42、al precautions are required during the perform-ance of any chemical procedure at all times. The first time that a hazardous material is noted in thetest procedures given in subsequent parts of ANSI/NAPM IT4.99, the hazard will be indicated by theword “DANGER” followed by a symbol consisting of angle

43、 brackets “” containing a letter whichdesignates the specific hazard. A double bracket “” will be used for particularly perilous situa-tions. In subsequent statements involving handling of these hazardous materials, only the hazardsymbol consisting of the brackets and letter(s) will be displayed. Fu

44、rthermore, for a given material,the hazard symbols will be used only once in a single paragraph.Detailed warnings for handling chemicals and their diluted solutions are beyond the scope of this partof ANSI/NAPM IT4.99.Employers shall provide training and health and safety information in conformance

45、with legalrequirements.The hazard code system defined in this part of ANSI/NAPM IT4.99 is intended to provide informationto the users and is not meant for compliance with any legal requirements for labeling as these varyfrom country to country.It is strongly recommended that anyone using these chemi

46、cals obtain from the manufacturerpertinent information about the hazards, handling, use, and disposal of these chemicals.4.2 Hazard information code systemHarmful if inhaled. Avoid breathing dust, vapor, mist, or gas. Use only with adequateventilation.Harmful if contact occurs. Avoid contact with ey

47、es, skin, or clothing. Wash thoroughlyafterhandling.Harmful if swallowed. Wash thoroughly after handling. If swallowed, obtain medical at-tention immediately. May be fatal if swallowed. If swallowed, obtain medical attention immediately.ANSI/NAPM IT4.99-19963Will burn. Keep away from heat, sparks, a

48、nd open flame. Use with adequate ventila-tion.1)Oxidizer. Contact with other material may cause fire. Do not store near combustible mate-rials.5 Requirements for reagents5.1 Handling and labelingReagents shall be handled in conformity with health and safety precautions as shown on containersor as gi

49、ven in other sources of such information. Proper labeling of prepared reagents includeschemical name, date of preparation, expiration date, restandardization date, name of preparer, andadequate health and safety precautions. The discharge of reagents shall comply with applicable en-vironmental regulations.5.2 PurityReagents used in the test procedures given in subsequent parts of ANSI/NAPM IT4.99 shall be certi-fied reagent-grade chemicals and shall meet appropriate standards or be chemicals of a purity ac-ceptable for the an
