《GB/T 25915.7-2010洁净室及相关受控环境 第7部分：隔离装置（洁净风罩、手套箱、隔离器、微环境）》由TC319（全国洁净室及相关受控环境标准化技术委员会）归口，主管部门为国家标准化管理委员会。

GB/T 25915.7-2010 Cleanrooms and associated controlled environments - Part 7: Separative devices (clean air hoods, gloveboxes, isolators and minienvironments)

1 Scope

This part of GB/T 25915 specifies the minimum requirements for the design, construction, installation, test and approval of separative devices, in those respects where they differ from cleanrooms as described in GB/T 25915.4 and GB/T 25915.5.

The application of this part of GB/T 25915 takes into account the following limitations.

——User requirements are as agreed by customer and supplier;

——Application-specific requirements are not addressed.;

——Specific processes to be accommodated in the separative-device installation are not specified;

——Fire, safety and other regulatory matters are not considered specifically; where appropriate, national and local regulations apply.

3 Terms and definitions

For the purposes of this document, the terms and definitions given in GB/T 25915.1-2010, GB/T 25915.2-2010 and GB/T 25915.4-2010 and the following apply.

3.1
access device
device for manipulation of processes, tools or products within the separative device

3.2
action level (general)
level set by the user in the context of controlled environments, which, when exceeded, requires immediate intervention, including the investigation of cause, and corrective action

3.3
alert level (general)
level set by the user in the context of controlled environments, giving early warning of a drift from normal conditions, which, when exceeded, shall result in increased attention to the process

3.4
barrier
means employed to provide separation

3.5
breach velocity
velocity through an aperture sufficient to prevent movement of matter in the direction opposite to the flow

3.6
containment
state achieved by separative devices with high degree of separation between operator and operation

3.7
decontamination
reduction of unwanted matter to a defined level
