This standard applies to food, as well as the measurement uncertainty assessment activities for quantitative analysis of environmental samples for the processing and storage of foodstuffs, as well as instrumental quantitative analysis of alternative microbiological routine colony counting methods. This standard does not apply to the most probable value counting methods and low levels of microbial analysis methods. The measurement uncertainty of the quantitative analysis of the animal word material is also referred to this standard.

This standard uses the redrafting method to modify the use of ISO /T S19036.2006 "Food and animal feed microbiological quantitative testing is not correct Guide to the Assessment of Qualifications (English version). This standard and ISO /T S19036.2006 "Guidelines for the assessment of the uncertainty of quantitative detection of microbiological foods and animal feeds" The technical differences that exist in the version are as follows. --- Remove all content related to animal feed in ISO /T S19036.2006, and only retain food-related content; --- Add the section of the normative reference document; --- Replace "ISO /IEC 17025.2005" in ISO /T S19036.2006 with "GB/T 27025-2008"; --- Amend the 2.1 "Note 3" in ISO /T S19036.2006 to the body content; --- ISO /T S19036.2006 4.2 and 5 "intralaboratory standard deviation (intralaboratorystandarddevia- " tionofreproducibility)" to explain and indicate the use of the name "reproducibility standard deviation in the laboratory" s reason; --- Amend the 5.2.2 "Note 1" and "Note 2" in ISO /T S19036.2006 to the body content; ---The numerical relationship between "sR" and "sIS" "scond" and "sres" in Tables A.1 to A.5 of ISO /T S19036.2006 and The calculation method of "scond" "sres" is expressed. This standard also made the following editorial changes. --- Use "a", "b", "c" and "d" to replace the English version of ISO /T S19036..2006 Appendix Table A.1~Table A.5 "i", "i", "ii" and "iv" in the column "(category)" to match the symbols used in the classification of the A.2.2 matrix; --- Remove the preamble and preface of the international standard.

Quantitative detection of food microorganisms Measurement uncertainty assessment guide1 ScopeThis standard specifies the measurement uncertainty and indication method for the quantitative detection of food microorganisms. This standard applies to food, as well as measurement uncertainty assessment for quantitative analysis of environmental samples used to monitor processed and stored foods. It is also applicable to the instrumental quantitative analysis method that can replace the conventional colony counting method of microorganisms. This standard does not apply to the most probable value counting methods and analytical methods for low levels of microorganisms. The measurement uncertainty assessment for the quantitative analysis of animal feed products is also referred to this standard.2 Normative referencesThe following documents are indispensable for the application of this document.

Guidance for the indication of uncertainty in measurement (GUM. 1995, Guidetotheexpressionofuncertaintyinmeasurement)3 Terms and definitionsThe following terms and definitions apply to this document. 3.1 Measurement uncertainty (ofmeasurement) A parameter associated with the measurement to characterize the dispersion imparted to the measured value. Note 1. This parameter can be the standard deviation or its multiple, or the half width of the confidence interval for a given confidence probability. Note 2. Measurement uncertainty is generally composed of many components, some of which can be measured by the statistical distribution of the measurement results, and the experimental standard Deviation characterization; while other components can be measured based on a hypothetical probability distribution of experience or other information, and also characterized by standard deviation. The measurement result is the best estimate of the measured value. All components of uncertainty are related to dispersion, including those affected by the system. The component of birth (as related to the correction value and the reference measurement standard). 3.2 Standard uncertainty standarduncertainty u(xi) Measurement uncertainty expressed in standard deviation. 3.3 Synthetic standard uncertainty combinedstandarduncertainty Uc(y) When the measurement result is obtained from several other quantities, the standard uncertainty calculated by the variance and covariance of the other quantities. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of RB/T 151-2016_English be delivered?Answer: Upon your order, we will start to translate RB/T 151-2016_English as soon as possible, and keep you informed of the progress.
