BS ISO 19679:2016规定了测定有氧运动程度和速率的试验方法 当塑料材料沉积在海洋砂质沉积物上 海水和海底，通过测量释放的二氧化碳。本试验方法是在实验室条件下模拟在不同环境中发现的栖息地 海洋中的海水/沉积物区域，例如阳光照射到海底的海底区域 （光区）在海洋科学中被称为亚海岸带。海洋沉积物中塑料材料生物降解的测定不在该区域内 本国际标准的适用范围。需氧生物降解的测量也可以通过监测耗氧量获得， 如ISO 18830所述。本国际标准中描述的条件可能并不总是符合最佳条件 发生最大程度生物降解的条件。交叉引用:ISO 14852:1999ISO 8245ISO 10210ISO 18830OECD TG 308购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS ISO 19679:2016 specifies a test method to determine the degree and rate of aerobic biodegradation of plastic materials when settled on marine sandy sediment at the interface between seawater and the seafloor, by measuring the evolved carbon dioxide.This test method is a simulation under laboratory conditions of the habitat found in different seawater/sediment-areas in the sea, e.g. in a benthic zone where sunlight reaches the ocean floor (photic zone) that, in marine science, is called sublittoral zoneThe determination of biodegradation of plastic materials buried in marine sediment is outside the scope of this International Standard.Measurement of aerobic biodegradation can also be obtained by monitoring the oxygen consumption, as described in ISO 18830.The conditions described in this International Standard may not always correspond to the optimum conditions for the maximum degree of biodegradation to occur.Cross References:ISO 14852:1999ISO 8245ISO 10210ISO 18830OECD TG 308All current amendments available at time of purchase are included with the purchase of this document.
