USP通则《659》 Packaging and Storage Requirements
Dry place: A place that does not exceed 40% average relative humidity at 20°(68° F) or the equivalent water vapor pressure at other temperatures. The determination may be made by direct measurement at the place. Determination is based on NLT 12 equally spaced measurements that encompass either a season, a year, or, where recorded data demonstrate, the storage period of the article. There may be values of up to 45%relative humidity provided that the average value does not exceed 40% relative humidity.Storage in a Container validated to protect the article from moisture vapor, including storage in bulk, is considered a Dry place.
USP干燥处指在控制的室温下平均相对湿度不超过40%,或者在其他温度下与40%相当的水份,如果平均相对湿度为40%,那么相对湿度有可能达到45%。
中国没有法规的规定。
