This standard shall apply to decayed urban domestic wastes and products from urban compost plants for agricultural use, with which industrial wastes and other wastes are not permitted to mix. This standard includes 15 indicators, such as impurities, granularity, death rate of ascarid egg, coliform level, total cadmium, total mercury, total lead, total chromium, and total arsenic. The wastes and products shall be applied for agricultural use when all of the first nine indicators are qualified, but exceptions can be made when any one of the last six indicators (organic materials, total nitrogen, total phosphor, total kalium, pH value, and moisture) fails to meet the stipulated standards (but cannot be lower than the average value of wastes permitted by the People's Republic of China). The standard also stipulates a number of issues regarding its implementation.
