学习贵刊2011年第9期刊载的《台式血压计示值误差的测量不确定度评定》一文后,对该文的观点,笔者有不同看法。首先,该文有处硬伤。该文在开头点明测量依据是JJG270-2008《血压计和血压表》检定规程,在文章结尾“测量不确定度的验证”中指出:因为U/|MPE|=0.22/0.5>1/3,故检定不可行。JJG270-2008之5.1.1.2规定:检定血压计、血压表的压力标准器的允许误差绝对值应不大于血压计、血压表允许误差绝对值的1/4。
Studying your issue No. 9, 2011 published in the “desktop meter pressure measurement error of measurement uncertainty,” a text, the author’s point of view, I have different views. First of all, the article is flawed. At the beginning of the article, the measurement was based on the JJG270-2008 “sphygmomanometer and sphygmomanometer” verification protocol. At the end of the article, “Verification of Measurement Uncertainty” states: Because U / | MPE | = 0.22 / 0.5> 1 / 3, so the test is not feasible. JJG270-2008 5.1.1.2 provides: verification sphygmomanometer, sphygmomanometer pressure standard error of the absolute value should not be greater than the sphygmomanometer, blood pressure meter allows the absolute value of 1/4.
