Foreword

GB/T 10322 "iron ore" is divided into eight sections. --- Part 1. iron ore sampling and sample preparation methods; --- Part 2. iron ore Experimental methods for evaluation of quality variation; --- Part 3. Experimental method of checking iron ore sampling precision; --- Part 4. Experimental methods of iron ore checking the bias of sampling; --- Part 5. Determination of iron ore consignment moisture content; --- Part 6. Determination of thermal cracking index of iron ore; --- Part 7. Determination of particle size distribution and screening of iron ore; --- Part 8. iron ore by nitrogen adsorption surface area than a single point. This section GB/T Part of 410,322. This section drafted in accordance with GB/T 1.1-2009 given rules. This Part replaces GB/T 10322.4-2000 "Experimental methods of iron ore checking the bias of sampling", this part of the GB/T 10322.4- Compared to 2000, in addition to editorial changes, the major technical changes are as follows. --- Added "outlier test - Grubbs test"; --- Added "selection bias test statistics." This section uses the translation method identical with ISO 3086.2006 "Experimental methods of iron ore checking the bias of sampling." Consistency correspondence between this part of international documents and normative references of our files are as follows. --- GB/T 10322.1-2014 iron ore sampling and sample preparation method (ISO 3082.2009, IDT) --- Experimental methods GB/T 10322.3-2000 iron ore check sampling precision (ISO 3085.1996, IDT) --- GB/T 10322.7-2004 Determination of particle size distribution of the iron ore sieving (ISO 4701.1999, IDT) This part made the following editorial changes. --- In the "Scope" increased "Experimental Methods This section applies to iron ore checking the bias of sampling."; --- "Normative references" is equivalent to using the national standard used in place of the corresponding international standard, and because the original ISO standard The text refers to "ISO 4701" standard, so in the "Normative references" Added "ISO 4701" references. This part is proposed by the China Iron and Steel Association. This part of the National Iron ore and direct reduced iron Standardization Technical Committee (SAC/TC317) centralized. This section is drafted. Baoshan Iron & Steel Co., Ltd., Metallurgical Industry Information Standards Institute, Ningbo Inspection and Quarantine Institute of Science and Technology Study hospital.

This part of the alternative criteria previously issued as follows. --- GB/T 10322.4-2000. Experimental methods of iron ore checking the bias of sampling

1 Scope

When in accordance with ISO 3082. When sampling method prescribed 2002, test methods specified in this part is based on ISO 3082.2002 stop Zone sampling method as a standard method to check iron ore sampling bias. Recommended prior bias test to check the mechanical sampling system. For a not fully comply with ISO 3082.2002 sampling systems usually do not want to deviate. Therefore, do not conform to ISO 3082. The main impact of 2002 when conditions have objections, do error checking experiments. If one believes in certain conditions, the bias may be large, So when using these conditions usually should be done bias test. This section applies to iron ore checking the bias of sampling experimental methods. Note. The analysis of experimental data described herein, this section applies to. a) to ISO 3082.2002 as the standard sample preparation method for the preparation of iron ore sample error checking. b) to ISO 4701 as a standard method of manual sieving, screening checked ore particle size distribution deviation. c) check from different places, such as loading and unloading port collecting samples of the same batch, the results obtained may have significant differences.

3 Terms and Definitions

Terms and definitions GB/T 20565-2006 defined apply to this document. Principle 4 They will be checking method (called Method B) and on the skill and experience are considered the standard method does not produce deviation (called Method A) to give The results are compared, there was no significant difference between the results of the method if Method A and B obtained in the statistical sense, can be used as a method B Daily Methods. In the 90% confidence interval, the average deviation by the deviation δ with the corresponding measured (see 5.2) to evaluate the comparative difference.

5 General Conditions

5.1 Test consignment number should be less than 10 batches. The need to increase the number of test batches, depending on the basis of at least 10 batches of the actual average
