Day after day, the same procedures must be carried out on the same material in the same way. Production control laboratories are standardized throughout. Each of these has special problems from an air conditioning standpoint. These may be divided as follows: (1) the control laboratory, (2) the research laboratory, and (3) the development laboratory. There are, however, several types of laboratories with varying fundamental air conditioning requirements. Although the majority of the specified conditions may vary slightly from a standard laboratory condition of 23 C (73.4 F) and 50 per cent relative humidity, the same type of air conditioning equipment with slight variations would be applicable to all. In the majority of cases, the specified conditions are suitable not only for the materials being tested, but also for the comfort and efficiency of the laboratory personnel. The American Society for Testing Materials has through its Subcommittee 14 on Conditioning and Weathering of Committee E-1 on Methods of Testing specified the temperature and humidity for the conditioning and testing of many materials.
