无尘室洁净度测试标准
洁净室*主要的要求上洁净度。洁净度检验的技术标准包括检验方法和检验仪器两部分，检验仪器标准十分重要，他是获得正确检验结果的先决条件.
中国将朱科学院空气调节研究所制定过亮相检测“尘埃粒子计数器”的国家标准。一向是转换灵敏度的检测方法，另一向是技术误差的检测方法。
上海市测试技术研究所制订了尘埃粒子计数器的国家计量检定规，检验仪器标准十分重程，规范了自净时间、重复性、离散度、分布准确度等技术指标的要求和检测方法。
ISO13323-1国际标准对于尘埃粒子计数器技术误差因素作了说明。
ISO21501-4提出凝结核计数器作为标准仪器，校准尘埃粒子计数
summary of presentaition
Cleanliness is the most important technicalrequirements for testing cleaniness inclunde testing methods andtesting equipement.The testing tandards of equipmen is veryimportant,it is the prerequisite of the correct testingresults.
Intitute of air-conditioning of Chineae Academy ofArchitecture had estalished two national tandards of"dust particlecounter".One detection method is converting sensitivity,and theother is counting error.
Shanghai Testing Techoiogy Research Instituteestablished national verification protocols of the dust particlecounter, regulating the specifications requirements and testmethods of self-purification time,repeatability,dispersion,accuracy of distribution and soon.
ISO 13323-1 international standsrds explained thecounting error factors for dust particle counter.
The ISO 21501-4 international standard propoesd thatcondensation nucleus counter can be used to calibrate countingvalue of the dust corpuscular counter as the standardinstrument
