ASTM E2042-04 可控区域和清洁室的清洁和维护的标准实施规程

This practice identifies methods for cleaning and maintaining controlled areas and clean rooms as defined by ISO 14644-1 and ISO 14644-2. Cleaning procedures are described, and cleaning frequency for different classes of facility are given. Compliance with this practice will make it easier and more likely that the required level of facility cleanliness will be maintained. A cleaner facility also will help to protect flight hardware from contamination and should reduce the frequency for cleaning flight hardware. This practice does not discuss operation and operational procedures for cleanrooms and controlled areas. Other documents such as IEST-RP-CC026 and Practice E 2352 provide recommended practices for operating cleanrooms and controlled areas. 1.1 This practice covers the procedures to be followed for the initial cleaning and normal maintenance of cleanrooms and controlled areas. This practice is applicable to aerospace clean areas where both particles and molecular films (NVR) must be controlled.1.2 The values stated in SI units are to be regarded as the standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

DIN EN ISO 14956:2003 空气质量.比照规定的测量不确定度评价测量规程的适用性

This International Standard specifies the procedure to estimate measurement uncertainty from actual or claimed values of all important performance characteristics of a method under stationary conditions. It allows to assess whether or not specified values for these performance characteristics comply with the required quality of a measured value at a stated measurand value. Furthermore, it includes procedures to evaluate the applicability of the measurement method based on laboratory performance and confirmatory field test and to establish requirements on dynamic behaviour of instruments. This International Standard is applicable to measurement procedures the output of which is a defined time average.#,,#
