标准摘要
[中文适用范围]： 该欧洲标准描述了用于鉴定防腐剂对土壤中微生物侵袭的长期抵抗力的测试程序。 它可以区分不具有长期耐受性、具有常规长期耐受性和具有增强长期耐受性的防腐饰面，以评估其在热带地区使用的适用性。 由于土埋试验是一个生物过程，并且试验土壤没有准确定义，因此本欧洲标准仅涵盖成品和未成品样本的比较。 [外文原描述]： ISO 11721-2:2003 describes a test procedure for identification of the long-term resistance of a rot-retardant finish against the attack of microorganisms in the soil. It permits a distinction to be made between rot-retardant finishes with no long-term resistance, with regular long-term resistance and with increased long-term resistance, in order to assess the suitability for use in the tropics. As the soil burial test is a biological process and the test soil not accurately defined, ISO 11721-2:2003 only covers the comparison of finished and unfinished specimens.
