Kit-of-parts construction is a special subset of pre-fabrication that not only attempts to achieve flexibility in assembly and efficiency in manufacture, but also by definition requires a capacity for demountability, disassembly, and reuse. Kit-of-parts structures can be assembled and taken apart in a variety of ways like a construction toy.
The aim of cleanroom suitability tests is to determine the suitability of machines and operating utilities (air conditioning, venting, etc.) for use in cleanrooms. The tests must be carried out using measurement techniques as particle emission behavior cannot be adequately assessed by the naked eye or similar means.
A cleanroom or clean room is an engineered space that maintains a very low concentration of airborne particulates. It is well isolated, well controlled from contamination , and actively cleansed. Such rooms are commonly needed for scientific research and in industrial production for all nanoscale processes, such as semiconductor manufacturing.
ISO 14698-1 was first written in 2003. ISO 14698-1 describes the principles and basic methodology for a formal system to assess and control biocontamination, where cleanroom technology is applied, in order that biocontamination in zones at risk can be monitored in a reproducible way and appropriate control measures can be selected.
ISO 14644-1 covers the classification of air cleanliness in cleanrooms and associated controlled environments. Classification in accordance with this standard is specified and accomplished exclusively in terms of concentration of airborne particulates. [6]
The cleanroom software engineering process is a software development process intended to produce software with a certifiable level of reliability. The central principles are software development based on formal methods, incremental implementation under statistical quality control, and statistically sound testing.
FED-STD-209 E Airborne Particulate Cleanliness Classes in Cleanrooms and Cleanzones was a federal standard concerning classification of air cleanliness, intended for use in environments like cleanrooms. The standard based its classifications on the measurement of airborne particles. [1]
The entire floor plan of these buildings can be more open because there are fewer fixed vertical penetrations through the floor and walls. Another way to use an interstitial space is to incorporate a design that divides the functions of the building into groups and localizes them.
