Introduction
GB/T 25915 adopts the ISO 14644 series of international standards, and the settings of each part are consistent with the international standards. It is proposed to be composed of 15 parts
constitute.
--- Part 1.Classification of air cleanliness by particle concentration. The purpose is to differentiate the degree of particle contamination.
--- Part 2.Monitoring of air particle concentration in clean rooms. The purpose is to guide the monitoring of particle contamination to avoid possible contamination
risk.
--- Part 3.Detection method. The purpose is to guide the detection of various pollution and related environmental elements in the clean room.
--- Part 4.Design, construction, start-up. The purpose is to guide the design, construction and start-up of clean rooms.
--- Part 5.Operation. The purpose is to guide the operation of the clean room.
--- Part 6.Vocabulary. The purpose is to unify and standardize technical terms.
--- Part 7.Isolation device (clean air hood, glove box, isolator, micro-environment). The aim is to propose the basis for isolators for cleanrooms
This requirement.
--- Part 8.Classification of air cleanliness (ACC) by chemical concentration. The purpose is to distinguish the degree of air chemical pollution.
--- Part 9.Classification of surface cleanliness by particle concentration. The purpose is to differentiate the degree of surface particle contamination.
--- Part 10.Classification of surface cleanliness by chemical concentration. The purpose is to differentiate the degree of chemical contamination of the surface.
--- Part 12.Technical requirements for monitoring the concentration of nanoparticles in the air. The aim is to propose the detection of particle contamination at the nanoscale
Require.
--- Part 13.Surface cleaning to achieve particle and chemical cleanliness requirements. The purpose is to put forward the cleaning requirements for the surface of the clean room to
Avoid the risk of possible particle and chemical contamination.
--- Part 14.Assessment of equipment suitability by particle concentration. The purpose is to pass the relevant equipment that may generate particle contamination in the clean room
A test to determine the suitability of the device.
--- Part 15.Evaluate the suitability of equipment and materials according to the concentration of gaseous chemicals. The purpose is to make possible
Tests for gaseous chemical contamination in clean rooms to determine the suitability of equipment and materials.
--- Part 16.Improve the energy efficiency of clean rooms and air purification devices. The aim is to save energy consumption in clean room operation.
The term "surface" generally refers to the interface between two phases. Surface herein refers specifically to a solid surface. A "clean surface" is one or more types of pollution
(particle contamination, chemical contamination) controlled surfaces. Cleanliness grades are specified in ISO 14644-9 and ISO 14644-10.cleanliness
(Cleanliness class) depends on the cleaning method. This article is a guide for selecting a cleaning method to achieve a specified degree of cleanliness. When choosing a cleaning protocol to
Consider. surface condition, cleaning requirements, type of contamination, cleaning techniques, material compatibility, evaluation methods, etc. Most cleaning methods can be
When cleaning more than one type of contamination, it is necessary to develop a cleaning option that applies to both particle and chemical contamination.
