This section GB/T 13747 Part 16.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This Part replaces GB/T 13747.16-1992 "zirconium and zirconium alloys chemical analysis of silver chloride turbidimetric method for the determination of chlorine." This section
Compared with GB/T 13747.16-1992, in addition to editorial changes outside the main technical changes are as follows.
--- Determination of silver chloride turbidity lower limit of 0.0020% adjusted to 0.0010% (see Chapter 1,.1992 Edition Chapter 1);
--- Removed the "reference standard" (Chapter.1992 of Chapter 2);
--- Chloride turbidity method by the "fluorescence spectrophotometer" to "spectrophotometer" (see 2.3,.1992 edition Chapter 5);
--- Increased ion selective electrode method (see Chapter 3);
--- Increase the sample terms (see 2.4);
--- Change the allowable difference to the precision clause (see 2.7 and 3.7, chapter 8 of the.1992 edition);
--- Added test report terms (see Chapter 9).
