BS 4651-3 on the determination of the residue after evaporation of ammonia solution for industrial use is useful for:

Organizations who want to certify an ISMS with sector-specific requirements

The laboratory test closely simulates practical conditions of application including pre-drying bacteria on a carrier

It is implicit that tanks and vessels conforming to BS EN 13121-2 should be made only by manufacturers who are competent and suitably equipped to fulfil all requirements

Methods of test for petroleum and its products. Crude petroleum and petroleum products. Determination of density. Oscillating U-tube method Ingestion-build-54484 General requirements that apply to1 Scope This International Standard specifies a method for the determination, using an oscillating U tube density meter, of the density of crude petroleum and related products within the range 600 kg m3 to 1 100 kg m3 which can be handled as single phase liquids at the test temperature and pressure. This International Standard is applicable to liquids of any vapour pressure as long as suitable precautions are taken to ensure that they remain in single
