Test Method for Fluorite Sampling and Sample Preparation1 ScopeThis standard specifies the fluorite sampling, sample preparation precision test method. This standard applies to the test method of precision specified in GB/T 22564.2 normative reference documentsThe following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document. Fluorite sampling and sample preparation GB/T 22564-20083 General rules3.1 Delivery lot In order to obtain reliable conclusions, it is recommended that more than 20 batches of the same fluorite delivery batch test, if not feasible, at least 10 should be tested Goods approved. If the delivery of the test is not sufficient, each batch can be divided into several parts, which can produce 10 or more delivery orders, and each As a separate delivery batch, according to GB/T 22564-2008 for testing. 3.2 samples and a large number of samples The minimum number of samples required for the test shall be 2 times the specified number of GB/T 22564-2008. If the number of samples required for daily sampling is n, the synthesis of a large sample, the test should take the minimum number of samples should be 2n, with these copies of the synthesis of two large samples, each sample has n copies. Note. If you can not reach the minimum number of copies, you can take n copies, and then divided into two copies, each is n/2 (see Chapter 6). 3.3 Sample preparation Sample preparation is carried out according to GB/T 22564-2008. 3.4 Test cycle It is recommended that tests should be continued even if precision tests have been made in order to check for possible sampling and sample preparation, The density changes. 3.5 method design The precision test is very laborious and is recommended as part of the day-to-day work.4 test method4.1 Sampling method Sampling method should be selected from GB/T 22564-2008 three methods, namely, system sampling, stratified sampling, secondary sampling. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 32553-2016_English be delivered?Answer: Upon your order, we will start to translate GB/T 32553-2016_English as soon as possible, and keep you informed of the progress.
