This document specifies the method for the determination of methamide release in toy materials by the climate chamber method. It is applicable to the determination of methamide release in toy materials, and the determination of methamide release in Miscellaneous materials is carried out by reference. The document cites a number of normative documents, including specifications and test methods for analytical laboratory water, interior decoration materials Carpets, Carpet Liners and Carpet Adhesive Hazardous Substances Release Limits, General Technical Conditions for Climate Chambers for Vocs Detection in Furniture. In terms of terms and definitions, reference is made to GB/T 31107-2014 and GB 18587-2001, in which the amount of amide released is defined as the amide mass released by the sample in the specified time and space, the climate compartment is composed of the cabin, the air circulation device, etc. Test equipment, the air exchange rate is the ratio of the amount of clean air entering the climate cabin per unit time to the capacity of the climate cabin, and the area carrying rate is the ratio of the exposure surface area of the sample to the capacity of the climate cabin. The principle is that the toy material is placed in the climate compartment under the specified operating conditions such as temperature, Humidity and air exchange rate according to the specified area loading rate, and the amide release environment is simulated to determine the amide release amount.
