- This part of ISO 11844 deals with the classification of Iow corrosivity of indoor atmospheres. The aim of this part of ISO 11844 is -- to characterise indoor atmospheric environments of Iow corrosivity that can affect metals and metallic coatings during storage, transport, installation or operational use, -- to set a consistent way of indoor corrosivity classification, and -- to prescribe procedures for derivation and estimation of indoor corrosivity categories. This part of ISO 11844 specifies technical metals, whose corrosion attack after a defined exposure period is used for determination of corrosivity categories of indoor atmospheres of Iow corrosivity. This part of ISO 11844 defines corrosivity categories of indoor atmospheres according to corrosion attack on standard specimens. This part of ISO 11844 indicates important parameters of indoor atmospheres that can serve as a basis for an estimation of indoor corrosivity. Selection of a method for determination of corrosion attack, description of standard specimens, its exposure conditions and evaluation are the subject of ISO 11844-2. Measurement of environmental parameters affecting indoor corrosivity is the subject of ISO 11844-3.

新的一年，从移液器检查开始
在QApp软件中，可输入由测量环境条件设备测量的数据，或者由连接到天平的气候模块自动测量和记录温度、气压和相对湿度。用于移液器检查的蒸发阱先决条件根据DIN EN ISO 8655第6部分附录A中的表A1，用温度和气压确定z因子。将测量的重量值乘以z因子，即可将重量值转换为体积值。根据标准DIN EN ISO 8655，还必须记录时间。...
