Specifies two methods for dry fertilizers only: the machine-tapping method and the hand-tapping method. Its principle is pouring the fertilizer from a specified funnel into a specified measuring cylinder of known volume, tapping the cylinder by means of a tapping machine or the walls of the cylinder by hand, and weighing the contents of the cylinder. If the fertilizer has absorbed moisture during…

The method is applicable to solid, but not powder fertilizers, dry only. It is not suitable for fertilizers which contain a large proportion of particles exceeding 5 mm in diameter. Its principle is pouring the fertilizer from a specified funnel into a specified measuring cylinder of known volume and weighing the contents of the cylinder. If the fertilizer has absorbed moisture during transport…

The method specified is based on extraction by methanol, purification and enzymatic desulfatation, determination using reversed-phase chromatography. Does not determine glucosinolates which are substituted on the glucose molecule. A rapid method for the determination of glucosinolates content using X-ray fluorescence spectrometry is the subject of ISO 9167-2.

Defines the requirements for type BFOC/2,5 connector sets. Type BFOC/2,5 is a sub-family of single position optical connector sets. They are characterized by a bayonet coupling mechanism and a cylindrical ferrule of 2,5 mm typical diameter. The sub-family includes plug-adapter-plug and plug-socket configurations. The contents of the corrigendum of May 1996 have been included in this copy.

Under normal conditions of use, it does not apply to oilseeds which do not yield oil which is completely liquid at 20 °C (e.g. shea, palm, illipe, cocoa, etc.). The method has been successfully tested on the following oilseeds: rapeseed, soya, sunflower seed and groundnuts. The reference method for the determination of the oil content of oilseeds is specified in ISO 659.

Applies to the terminal markings for the main circuits of valve device stacks and assemblies and of factory assembled integrated convertor equipment. The terminal markings refer to stacks, assemblies and equipment comprising semiconductor valve devices. Specifies a logical alphanumeric marking system for the identification of the external terminals of the main power circuits in a stack, valve…

Specifies methods for determining silica, alumina, titania, iron oxide and oxides of manganese, chromium, calcium, magnesium, sodium, potassium and lithium. It also specifies methods for determining the loss of ignition of magnesite and dolomite, and of refractories based on these raw materials. Annex A describes a method for determining the boron content of magnesites only.

The method is not necessarily suitable for latices from natural sources other than Hevea brasiliensis. It is not suitable for compounded latex or vulcanized latex.

Gives methods of test for the materials defined in IEC 60893-1. The contents of the corrigendum of September 1995 have been included in this copy.

The contents of the corrigenda of May 1992 and December 1994 have been included in this copy. It has the status of a horizontal standard in accordance with IEC Guide 108.
