GB/T 19277-2003 in English

《GB/T 19277-2003受控堆肥条件下材料最终需氧生物分解和崩解能力的测定 采用测定释放的二氧化碳的方法》由TC48（全国塑料制品标准化技术委员会）归口，主管部门为中国轻工业联合会。
本标准规定了一种测定方法，用于将材料作为有机化合物在受控的堆肥化条件下，通过测定其排放的二氧化碳量来确定其最终需氧生物分解能力，同时测定在试验结束时材料的崩解程度。本方法模拟混入城市固体废料中有机部分的典型需氧堆肥处理条件。试验材料曝置在堆肥产生培养土中，在温度氧浓度和湿度都受到严格检测和控制的环境条件下进行堆肥。本方法测定试验材料中碳转化成释放出的二氧化碳的转化百分率。

Scope

This standard specifies a method for determining the final aerobic biodegradability of materials as organic compounds under controlled composting conditions by measuring the amount of carbon dioxide emitted, and at the same time determining the biodegradability of materials at the end of the test. Degree of disintegration. This method simulates typical aerobic composting conditions for the organic fraction of mixed municipal solid waste. The test materials are exposed to the culture soil produced by composting, and the composting is carried out under the environmental conditions that the temperature, oxygen concentration and humidity are strictly detected and controlled. This method determines the percent conversion of carbon in the test material to liberated carbon dioxide. The conditions described in this standard do not always correspond to the optimum conditions for maximum biodegradation to occur.
