Introduction

The uncertainty of measurement results is very important in interpreting the measurement results: Without a quantitative assessment of uncertainty, the measurement results cannot be determined: Whether the observed differences between fruits contain information other than experimental variation, whether the test items comply with the specifications, and whether they exceed the regulations under which they are based: limit: Without uncertainty information, there is a risk of erroneous processing results, and the resulting erroneous decisions may lead to unnecessary industrial losses, wrongful legal prosecution or harm to health and adverse social consequences: In accordance with GB/T 27025 accreditation and related system requirements, laboratories need to evaluate the uncertainty of measurement and test results and provide relevant uncertainty: JJF1059:1 is a widely adopted standard method, but it is only applicable when the measurement process model is known: However, most standard testing methods are completed based on the collaborative testing proposed in GB/T 6379:2: This document provides an economically useful This method is an effective uncertainty estimation method that fully complies with the relevant principles of GUM and also takes into account the method performance obtained from collaborative experiments: data: The general method requirements of this document are as follows: ---According to the test method repeatability, reproducibility and accuracy estimates obtained from the collaborative testing described in GB/T 6379:2, the Obtained from published information using test methods: This information provides within-laboratory and between-laboratory variance component estimates: value, and also involves the uncertainty estimate of the correctness of the test method: ---In collaborative experiments or intermediate precision studies, the laboratory determines the effectiveness of its test methods by checking its own bias and precision: Check whether the method meets the performance specified by the method to confirm that the data published by the method can be applied to the laboratory measurement results: ---In synergistic experiments or intermediate precision studies, all the influencing quantities of the measurement results that are not included need to be identified, and the resulting The resulting relevant variance needs to be quantified: According to the method described by GUM, an evaluation of uncertainty is given by synthesizing the relevant variance estimates and taking into account other factors: Determination is sometimes regarded as the uncertainty of the final representation: The use of reproducibility or intermediate precision data to estimate uncertainty is often referred to as the "top-down" approach: The divergence of results given by collaborative testing or intermediate precision studies is often compared with the measurement uncertainty evaluation value of GUM to determine Tests comprehensive understanding of methods: Such comparison helps provide more effective method consistency under the same parameter evaluation: Utilize estimates of repeatability, reproducibility, and accuracy Guidelines for assessing measurement uncertainty`

1 Scope

This document gives guidance on: ---Use the precision results of GB/T 6379:2 to evaluate the measurement uncertainty; ---Use the intermediate precision results of GB/T 6379:3 to evaluate the measurement uncertainty; --- Comparison of uncertainty assessment results obtained using the method of this document and the uncertainty propagation law method (GUM method) (see section Chapter 14): This document applies to the uncertainty assessment of results in all areas of measurement and testing: This document does not apply where there is no method reproducibility or intermediate precision and only repeatability: This document assumes that identified and non-negligible system effects have been corrected, either numerically using measurement methods, or by finding the system effects are eliminated: This document presents an effective method for uncertainty assessment, but other suitable assessment methods may also be used: The measurement results, methods and processes mentioned in this document can generally also be understood as test results, methods and processes:
