Inspection and testing laboratory design and construction of the technical requirements Part 3. Food Laboratory

1 Scope

China's national technical requirements for the design and construction of food inspection and testing laboratories. It is Part 3 of GB/T 32146 and specifies the overall planning and design, the construction, the functional design, the architectural design, the environment and facilities, and the safety requirements for food laboratories, with five normative annexes covering the special technical requirements for a food microbiology laboratory, the special technical requirements for a food molecular biology laboratory, the food toxicology laboratory, typical layouts for food laboratories, and the description of the centralised gas supply systems. A food laboratory has a design problem that an electrical laboratory does not: it works with living organisms and with trace contaminants, and both create contamination risks that run in opposite directions. Microbiology needs containment - the organisms cultured must not escape into the building or into the people working there, so air flows inward, waste is sterilised before it leaves, and the working areas are separated by anterooms. Molecular biology needs the opposite: the analysis amplifies a few molecules of DNA into a measurable quantity, so a trace of amplified product carried on a glove or in the air into the room where samples are prepared will produce a false positive that no control detects. The laboratory is therefore divided into rooms with a one-way workflow, and air flows outward from the clean end. Trace chemical analysis adds a third and unrelated constraint, since the contaminants being measured are present in the ordinary environment at the levels being determined. The typical layouts in Annex D are the practical consequence of all three, and the gas supply annex reflects that a food laboratory runs many chromatographs and needs a piped supply rather than cylinders at every bench. Issued on 10 December 2015 and in force since 1 July 2016.

GB/T 32146 provisions of this part of the overall planning and design and construction of food laboratories, functional design, architectural design, environmental facilities, Safety and other technical requirements. This section applies to new construction, renovation and expansion of the food laboratory design and construction.
