本欧洲标准规定了用于评估其对EN 206侵蚀性等级的土壤酸度的测定程序。根据Baumann-Gully的酸度为测定可交换氢离子浓度的结果腐殖质颗粒的土壤释放

This European Standard specifies the procedure for the determination of the degree of acidity of a soil to be used for evaluating its class of aggressiveness to EN 206. The degree of acidity according to Baumann-Gully is the result of the determination of exchangeable hydrogen ion concentration that humic particles of a soil release.
