Specifies a method for the detrmination of the pore size of filters, porous bearings, porous electrodes and other parts with interconnected porosity. The bubble test shall be considered as a quality control test and not as a test for defining filter grades of determining exact pore size and pore size distribution.

Includes the principal widths to be retained for narrow one-time paper or plastic printing ribbons (19 mm width and less) intended for office machines and printing machines used for information processing. Also defines the location of the marking indicating the approach of the end of the ribbons for office machines. Reference: ISO 2257.

Describes procedures for the removal of certain commonly found types of non-fibrous substances from fibres. Fibres to which the procedures are applicable and those to which they are not applicable are listed in the table, in relation to the non-fibrous substances to be removed. The names of these fibres are defined in ISO 2076.

The method specifies the sampling (with figure) and defines the areas for the physical testing and chemical analysis of hand-knotted carpets. It is applicable to most carpets in which the knots are tied by finger or by hook. Each carpet should be tested separately.

The method is applicable in the range from about -50 °C to about +250 °C. the determination can be carried out directly on the sample as received, or on the dried sample, or on both. In which of these conditions the sample is to be tested will be stated in the specific test method for each material. The principle is based on cooling the liquid or liquefied sample and observation of the…
