36 is the thirty-sixth part of the second part of the BS 684 series that specifies a gas-liquid chromatographic method for the determination of butylhydroxyanisole (tert-butyl-4-methoxyphenol) (BHA) and butylhydroxytoluene (2

3: Requirement for the re-measurement of uniformity was added as follows

an ISMS based on BS ISO/IEC 27001 needs BS ISO/IEC 27007:2011

The calculation of the short-circuit currents based on the rated data of the electrical equipment and the topological arrangement of the system has the advantage of being possible both for existing systems and for systems at the planning stage

External cathodic protection of well casing Ingestion-build-93833 or of rejecting what is1 Scope This European Standard specifies methods used to evaluate the external corrosion hazards of well casings, as well as cathodic protection means and devices to be implemented in order to prevent corrosion of the external part of these wells in contact with the soil. This European Standard applies to any gas, oil or water well with metallic casing, whether cemented or not. However, in special conditions (shallow casing: e. g. 50 m, and
