1 Scope

This standard specifies the chemical analysis of metallurgical products basic terminology. This standard applies to the preparation of metallurgical products for chemical analysis of national standards, industry standards, corporate standards. Preparation of technical documents, books and school Operation and exchange of technology can also be applied in business dealings.

2 Terms

2.1 General 2.1.1 Chemical analysis chemicalanalysis Get chemical composition from the material, shape and the presence of technical information. 2.1.2 Detection detection Confirm the specific nature of the sample and determining the presence or absence of a substance in the operation. 2.1.3 Determination of determination Get all of the operations of a substance characteristic values \u200b\u200bexperimentally. 2.1.4 Parallel determination paraleldetermination Take several samples of the same measurement carried out simultaneously under the same operating conditions. 2.1.5 Measurement range rangeofdetermination Method for determination of the lower limit to the range of measurement caps. 2.1.6 Determination limit maximumlimitofdetermination The actual method of analysis can be determined to a certain maximum amount or concentration of the components. 2.1.7 Detection limit (limit of determination, the limit of quantification) minimumlimitofdetermination [limitofdetermination, quantificationlimit] The minimum amount or concentration can be determined to the actual analysis of the particular component. International Union of Pure and Applied Chemistry (IUPAC) requirements to 10 times the standard deviation of the blank signal values \u200b\u200bcorresponding to the concentration (or mass) for the determination of the lower limit, also known as the limit of determination. 1997 adopted by the IUPAC "Analysis of the term Outline", the limit of determination renamed the limit of quantification. 2.1.8 Quantity quantity Physical short. Phenomenon, body or substance that may be distinguished qualitatively and quantitatively determined by an attribute. ......
