ISO Standards

ISO 302:2015 specifies a method for the determination of the Kappa number of pulp. The Kappa number is an indication of the lignin content or bleachability of pulp. ISO 302:2015 is applicable to all kinds of chemical pulps and semi-chemical pulps within the Kappa number range 1 to 100. For pulps with a Kappa number […]

ISO 225:2010 defines the symbols and gives descriptions of the dimensions of bolts, screws,studs and nuts for use in the appropriate product standards and drawings. NOTE 1 The figures of the fasteners in this International Standard are given only as examples.

ISO 199:2014 specifies dimensional characteristics, limit deviations from nominal values, and tolerance values to define the interface (except chamfers) of thrust rolling bearings. Nominal boundary dimensions are defined in ISO 104 [1] . This International Standard is not applicable to certain thrust bearings (e.g. thrust needle roller bearings) or for particular fields of application (e.g.

ISO 104:2015 specifies preferred boundary dimensions for single-direction and double-direction thrust bearings with flat back faces. In addition, it gives the minimum bore diameters of housing washers and maximum outside diametersof shaft washers of bearings in dimension series 11, 12, 13, 14, 22, 23 and 24.

ISO 464:2015 specifies the snap ring groove dimensions and tolerance values, chamfer dimensions on the snap ring groove side of the outer ring, and the snap ring dimensions and tolerance values for radial bearings in the dimension series 18 and 19 and the diameter series 0, 2, 3, and 4 (except dimension series 00, 82,
