Soil quality. Determination of effective cation exchange capacity and base saturation level using barium chloride solution1 Scope This document specifies a method for the determination of the cation exchange capacity (CEC) at the pH of the soil and for the determination of the content of exchangeable sodium, potassium, calcium and magnesium in soil. This document is applicable to all types of air dried soil samples. ISO 11464 can be used for pre treatment.

BS EN 62129-1 is a safety standard on the calibration of wavelength/optical frequency measurement instruments

This document specifies the requirements for product quality and product testing of enamelled valves and pressure pipe fittings for untreated and potable water supply
