Describes a method intended to assess the suitability of powdered mateial for volumetric feeding device and the potential dust hazard. The principle consists in sieving a test portion through a nest of sieves and determining the masses retained on each sieve. The result is then calculated as percentages passing through the different sieves.

Applies to all types of dried milk. The principle is based on the preparation of reconstituted milk by addition of water to a test portion of dried milk. The reconstituted milk is titrated with sodium hydroxide solution using phenolphthalein as indicator and cobalt(II) sulphate as reference colour solution. The number of millilitres used in the titration is multiplied by the factor 2 in order to…

Specifies the performance test methods and requirements for seals used in disc brake cylinders. Applies to solid section type seals (square, rectangular, 'O'-ring) mounted stationary in the cylinder bore or on the movable piston of disc brakes. Describes the apparatus, preparation of specimens, and test procedures; lists test requirements.

Specifies performance tests for moulded rubber boots used as end closures on drum type brake cylinders. These boots prevent the entrance of dirt and moisture which could cause corrosion and otherwise impair wheel brake operation. Applies to boots of both plain and reinforcement insert types. Requirements relating to chemical composition, tensile strength or elongation at break of the rubber…

Is limited to qualitative tests. Table 2 indicates the suitablility of each test for some of the most usual types of metallic coatings. Most of the tests are capable of destroying both the coating and the article being tested. Some destroy the coating only, but it should not be assumed that the articles are undamaged. When particular methods of adhesion testing are included in International…

ISO 2861-2:1980 specifies the dimensions of quick-release couplings of the screwed type as used in vacuum technology, as well as those of the “O” rings and the insert which are associated with these tailpieces to ensure coupling tightness. General information is also included which refers to the clamped quick-release coupling standardized internationally in ISO 2861-1, with which the screwed…

These limits are generally appropriate for the products listed. If, however, an International Standard has been issued for an individual product, the method specified there shall be used. Does not apply to articles whose surfaces are composed of mixtures of insulating and conducting areas or articles with substantial surface area of insulating material. A defined system of electrodes is used for…

Determines the minimum information to be included in the specification sheets of document copying machines for the users to compare directly the characteristics of different machines.

Specifies the requirements and gives definitions for the raw materials. 23 C is the standard temperature for the test unless otherwise agreed. Stricter requirements may be agreed between the interested parties. Cancels and replaces the ISO Recommendation R 150-1960.
