Sawn timber of broadleaved species — Defects — Terms and definitions
Relates to classification in ISO 1029 and ISO 2299. Covers unplaned sawn timber and such surfaced to size or planed but without profiling. Examples are shown in many figures. Is a trilingual edition.
Covers the most suitable conditions for the storage. Specifies temperature, humidity, light, oxygen and ozone, deformation, contacts with various materials, containers, wrapping and covering materials, rotation of stocks and cleaning.
Lya down the speeds (number of revolutions or strokes per minute) and the feeds (in millimetres or in inches, per minute, per revolution, or per stroke) of machine tools working by removal of metal an driven directly by an electrical motor. Is not applicable to machines with continuous speed variations, feeds for thread forming, etc.
Machine tools — Lathe centres — Sizes for interchangeability
The scope should not be regarded as restricted to lathes only, but may be extended to all the other machine tools with centres of the same type. Specifies designation and sizes in millimetres and in inches.
The first operation of the sampling procedure is inspection of the consignment. Before sampling the contents of the containers shall be homogenized. In the case of large containers five partial samples shall be withdrawn from each container at different specified depths. For each container the five partial samples shall be bulked and homogenizied. From this bulk three representative samples shall…
Aluminium oxide primarily used for the production of aluminium — Determination of boron content — Cu...
Applicable to products having boron oxide contents of more than 0.0006 % (m/m). With sufficiently sensitive apparatus, the lower limit of application may be extended to 0.00008 % (m/m). The test portion is dissolved in phosphoric acid. Separation of the boron by distillation as methyl borate. Formation of a red coloured complex between the boron and the curcumin reagent at pH 7.…
