用气体组分分析法分析钢的质量保证

Quality assurance of analysis is often demanded
by a wide range of users interested in the analysis
of raw steel or finished steel products. These
users include international public and private
organizations, such as the ISO, JIS, ASTM,
ASME, LA, and Defense Agencies, manufacturers,
such as automobile makers, and individual
users.
The most important factor required by any quality
assurance is the accuracy of analysis making
it possible for all values analyzed to meet authorized
standards. The second most important factor
is the ease of tracking back to find when,
how, by who, and under what conditions or environments
the analysis was made.
In order to satisfy these factors, the above tasks
must be standardized and prepared in writing as
guidelines or references. Their contents must
provide steps to make it possible to ensure that
the results of analysis will be obtained by taking
the provided steps. As an example, quality assurances
of analysis are explained below with the
carbon detection method (EMIA) and nitrogen
detection method (EMGA) provided in Steel Analysis
(Analysis of Control of Processes in 24-hour
Operation). The example introduced here is typical.
Other quality assurance systems may be
applied if they are proper and suitable. 红外碳硫分析仪（EMIA-920V2系列） 红外碳硫分析仪（EMIA-320V2）
