Plastics. Determination of the ultimate anaerobic biodegradation of plastic materials in an aqueous system. Method by measurement of biogas production Ingestion-build-583201 Scope This International Standard specifies a method for the determination of the ultimate anaerobic biodegradability of plastics by anaerobic microorganisms. The conditions described in this International Standard do not necessarily correspond to the optimum conditions for the maximum degree of biodegradation to occur. The test calls for exposure of the test material to sludge for a period of up to 90 d, which is longer than the normal sludge

BS EN 1982:2008 replaces BS EN 1982:1999 which has been withdrawn

The standard gives clear and up-to-date recommendations and incorporates all aspects that support the provision of advice services

BS EN 61300-3-25 also describes the measurement of concentricity of ferrules and ferrules with assembled fibres

BS 5655-2 provides rules which have a direct influence on the choice of landing doors and on the specification and design of electrical control systems

Test execution

BS EN 60793-1-30 describes procedures for briefly applying a specified tensile load as a proof test to continuous lengths of optical fibre
