Wherein Section 9, Section 10 and Section 11 corresponds to GB/T 12763-1991 is a new section.
This section GB/T Part of 412,763.
This Part replaces GB/T 12763.4-1991 "oceanographic survey - Part 4. Seawater chemical elements observation."
This section compared with the GB/T 12763.4-1991 The main changes are as follows.
--- According to GB/T 1.1-2000. provisions "Standardization Guide Part 1 standard structure and write rules," revised standard
Accurate formatting, are. the "chapter" to "chapter"; terms and definitions are a separate article; the various elements of "determination" deleted within
After Yung supplemented, classified as "technical specifications", "principle of the method," "Reagent and preparation", "instruments and equipment", "means taking water samples, pre
Handling and storage "," measurement procedure "and" computing "and seven items;
--- The original "technical design" to "the principles of survey design requirement" (1991 version 3, this version 4.1);
--- The original "pre-sea ready" to "survey plan and organize the implementation" (1991 version 6, edition 4.2);
"Quality Control of the Determination" --- original amended as "quality assurance and quality control analysis" (1991 version 5 edition 4.3);
--- The original "measurement of ammonia," renamed the "salt Determination" (1991 edition ninth chapter, edition of 12);
--- The original "chlorine determination (silver titration)" with "the determination of chloride (silver titration)" (1991 edition of the tenth chapter, Excerpts
13);
--- Redesigned "Record table format" (see Annex E);
--- Added two analytical methods "determination of total phosphorus (persulfate oxidation method)" and "Determination of Total Nitrogen (persulfate oxidation method)" and so on (Excerpts
14 edition of 15);
--- Added "dissolved oxygen (spectrophotometry)" as a normative appendix is incorporated (see Appendix D);
--- Added "dissolved oxygen (spectrophotometry) record", "Determination of Total Record," and "dissolved oxygen (spectrophotometry) K
Value is recorded, "and" Determination of total nitrogen as an information record in Appendix Table "and" seawater chemical element Data Report "and other five format record table
(See Table E.13, table E.14, table E.15, E.16 and table Table E.17).
