Determination of GB/T 5009.4 ash in foods GB 5491 grain and oilseeds testing for sampling, and sample method GB/T 24895 Inspection of grain NIR calibration model validation and network management and maintenance of general rules3 Terms and DefinitionsGB/T 24895 and defined by the following terms and definitions apply to this standard. 3.1 The residue was burned after the sample, representative of the minerals present in the sample. Principle 4 There is a high correlation between the ash content in wheat flour and cellulose content. NIR calibration for wheat flour, bran and cellulose components The correlation is very close. Near Infrared analysis by determining the cellulose content in wheat flour obtained ash content of wheat flour.5 EquipmentNIR analyzer. Add OILS NIR network equipment should comply with GB/T 24895 requirements. No added OILS near infrared Analysis of network equipment, verify eligibility in accordance with GB/T 24895 in the provisions relating to the calibration model validation.6 Determination6.1 preparation before the test 6.1.1 Sampling and sample decimation executed according to the provisions of GB 5491. 6.1.2 according to the near-infrared analyzer (Chapter 5) specification requirements for instrument self-test and warm-up test. 6.1.3 In the case where the state of at least a day of near infrared analyzer (Chapter 5) monitor with a monitor samples. You should track and monitor the daily knot As a result, the measurement results of the same sample monitoring compared with the initial measurement result, shall ensure compliance with the provisions of 9.2. Preparation of the samples in accordance with Appendix monitor A provision of execution. 6.1.4 The monitoring sample measurement results do not meet the requirements of 9.2, should stop using, and reported to the network administrator or equipment suppliers to be adjusted ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 24872-2010_English be delivered?Answer: Upon your order, we will start to translate GB/T 24872-2010_English as soon as possible, and keep you informed of the progress.
