LBMA | Purity of Gold

The LBMA Good Delivery system has rules for rounding five-figure gold assays to four figures. In most cases, if the fifth figure is a 6 or greater, the result is rounded up. So an assay of 997.46 would be rounded up to 997.5. There are three fineness levels where rounding up is not allowed: 995, 999.9 and 1,000.

Fibre Fineness

The main physical unit of fibre fineness is 1 tex, which is equal to 1000 m of a fibre/yarn weighing 1 g. For fibres, the unit dtex is often used, which is equivalent to 1 g/10 000 m. Typical values for micro-fibres are below 1 dtex, for cotton fibres around 1.6 dtex, for wool often around 3.5 dtex and for coarse carpet fibres above 7 dtex.
