Foreword
This standard replaces GB/T 11007-1989 "Conductivity Meter Test Method."
This standard is the technical content and the main difference between the original criteria are as follows.
--- Reference standards are using the latest version;
--- Table 1 Reference conditions according to GB/T 11606 modified. Wherein. the ambient temperature by the "(25 ± 2) ℃" to "(23 ± 2) ℃";
Atmospheric pressure from "Pending" to "(86 ~ 106) kPa"; increase Table 1 Note 1, 2;
--- According conductivity meter display case, original standard conductance (symbol G) were changed to electric conductivity (symbol κ);
--- Figure 1, the original standard temperature increase measured with analog devices (resistance box);
--- Original standard "basic error" was changed to "inherent error";
--- According to the current display of conductivity meter, conductivity measurement range to make the appropriate changes, see Table 3;
--- Cleaned before testing the conductivity cell from the conductivity of deionized water was "not larger than 0.2 × 10-6S · cm-1" to "no more than 1 ×
10-6S · cm-1 ";
--- Table 3, the original standard conductivity range of the standard solution does not have the number corresponding relationship, now changed to two tables (Tables 3 and 4);
--- 5.3.2 basic error in the original standard test method for supporting an increase in the Standard Test Method for unknown cell constant and temperature increases
error;
--- Original standard 5.3.9 Temperature compensation error from the operability has been modified; instead the temperature coefficient of the temperature coefficient compensation error
Indication Error number representation;
--- Original standard 5.3.10 constant compensator error indication error switch cell constant representation;
--- Cancel the original standard safety test methods damp pretreatment;
--- Cancel the original standard tables 5.4.3 dielectric strength test 4.
The standard proposed by China Machinery Industry Federation.
The standard measurement and control of the instruments Standardization Technical Committee Technical Committee under the jurisdiction of the national industrial processes.
This standard is drafted by. Shanghai Precision & Scientific Instrument Co., Ltd.
The main drafters of this standard. Wang Qiaomei, Gu Minjie, Kim Chun law.
This standard superseded standard previously issued as follows.
--- GB/T 11007-1989.
