Determination of platinum in platinum jewellery alloys. Gravimetric method after reduction with mercury(I) chloride Ingestion-build-276583 Why should you use BS

Why should you use BS 3999-16 - Measuring the performance of electric warming plates

The emphasis is on providing conditions for the materials and structures of collection items that will help prevent rapid deterioration or irreversible damage

Determination by means of two-point measurement (measurement of diameters)

for example bucket trucks

Determination of platinum in platinum jewellery alloys. Gravimetric method after reduction with mercury(I) chloride Ingestion-build-276583 Why should you use BS1 Scope This International Standard specifies a gravimetric method for the determination of platinum in platinum jewellery alloys, preferably within the range of fineness stated in ISO 9202. The procedure applies specifically to platinum alloys incorporating palladium, iridium, rhodium, copper, cobalt, gold, ruthenium, gallium, chromium, indium and less than 5 % tungsten. Some modifications are indicated where palladium, iridium, rhodium, gold or
