適用范圍：The scope of this standard is the sludges, i.e. and sludges products from: —storm water handling; —night soil; —urban wastewater collecting systems; —urban wastewater treatment plants; —treating industrial wastewater similar to urban wastewater (as defined in Directive 91/271 EEC); —water supply treatment plants; —water distribution systems; —but excluding hazardous sludges from industry. This method is applicable to the determination of pH values of sludges which include liquid, paste-like or solid matter. If the sludge sample is sufficiently liquid, direct measurement should be made. If the sludge sample contains relatively high percentages of solids the measurement should be carried out after dilution with water.
