This machine standard is the same as the international standard 5O6344-1,19sHc medical light shop branch: Part 9 of the effective material P240-F||This book is BT314--18 through-pull sedimentation pipe and G—coating with a single material micro-starting degree. This book has added 150,P2G00 2 pull numbers to make the standard consistent with the content and editing specifications. The following parts are attached: the first part is the range of the test: the relevant product 19 ~ P group test: the first part is the price of P2F250 and the internal determination: the fourth part is the replacement of R544-6R5 and 39358-188 (R544-6R5 and 39358-188). This standard is proposed by the National Medical Materials Committee of the Ministry of Industry and Information Technology of Japan. The main contributors to this standard are: Bao Hua, Feng Li, Xiang Zu.GR/T9258. 3 -2000
ISO Foreword
[S(International Organization for Standardization)National Standards (International Organization for Standardization)National Standards (International Organization for Standardization)The international standard is a product that is passed through the door. For a professional technical committee, every pressure is more than the right of the technical committee. The ISO also uses the single-level membership of the United Nations to make full use of its work. S is in close contact with all the international electrical product standards in the market. The technical staff adopts the international standard source product ticket. The ticket has a negative position. This standard: Use as the international standard version,

Please use the equation of the pipe and the scientific drop in the settling. 4.3.4 Measure the starting point of the dangerous object and judge the time to stop. 4-3.5 The new part of the German determination is the equivalent of the particle size. The source of the particle size is estimated to be soft and the sample is the smallest particle size. 3.6 The pull stop is not the value of the drop. , and teach the installation time what a, the situation is correct to ("i.

see the report 3 (Compared with the table 3 in /0268.1-2:5.2 Determination method and specification record:
the nature of the determination to the period of sensitivity of the donation is indicated in the instrument used, so the determination and the lack of release marks to the determination of the micro powder sedimentation rate should be collected:
the determination number-1-light medium sedimentation rate is discussed,
3 micro-degrees are 11500--3560 from the exclusive authorization group of products
a chemical measurement lamp and P-induced powder standard Emperor Shu Mei degree dot system, only the kidney resistance is used, the high ratio is determined..3
first use other instruments, the sound model is provided according to the instruction manual of the instrument, the work is not returned to the inflammation type diameter period of the original result of the tube fittings. Before and after the establishment of the station, the base position and the price will be increased, and the actual measured values ​​will be increased. Pay attention to the corresponding angle number and the following points: GB/T9258.3:2000. The standard chicken certificate is marked with the corresponding value of the measured value. In this way, the clinical test of the disease micro-sound is also added to the standard. The corresponding value of the certificate period will be calculated based on the company's measurement and the usual question: the test result of the sample and the d modification will be carried out on the Beijing 23rd position. The test piece of the test piece is d, and the sense of stop position is 10. 0 &T.
