Cranes — Information to be provided — Part 5: Overhead travelling cranes and portal bridge cranes
Specifies information to be provided by: a purchaser in enquiring about or ordering a crane, a manufacturer in tendering for or supplying a crane. Annex A forms an integral part of this standard.
1. Scope
1.1 This Standard specifies the requirements for all types of welded aluminum construction, and is of general application. There are, however, special Standards which may be used for particular products, such as, pressure vessels and pipelines.
1.2 This Standard gives provisions for gas metal arc (GMAW), gas tungsten arc (GTAW), plasma arc (PAW) processes, and stud (SW )…
Rotary shaft lip type seals — Part 5: Identification of visual imperfections
This part shows and identifies visual imperfections on typical rotary shaft lip type seals, dimensionally standardized in ISO 6194-1, as a convenience for purchasers and manufacturers in their discussions about the importance of imperfections in different applications. It defines and classifies typical surface imperfections that often impair the function of the rotary shaft lip type seal.
Textiles — Determination of thermal resistance — Part 2: High thermal resistance
Relates to fabrics, fabric assemblies and fleeces. Applies to materials whose thermal resistance is within about 0.2 m^2·K/W to 2.0 m^2·K/W. This value of resistance is obtained by measuring the energy required to maintain an invariable difference of temperature in a heating body covered with the fabric to be tested as compared with the ambient temperature. Details of heating body are described…
Pigments and extenders — Methods of dispersion for assessment of dispersion characteristics — Part 1...
Gives an introduction to the various methods described in the subsequent parts for dispersing pigments in a particular binder system. Methods for assessing the characteristics of the dispersion so produced are described in ISO 8781. The results allow to draw inferences about the dispersion that may be obtained under manufacturing conditions.
Deals with a method for determining the presence and approximate concentration of viable aerobic and facultative anaerobic micro-organisms. Annex about preparation of media and plates.
Applies to the steel grades listed in table 1, which are generally used in the work-hardened condition in the form of strip up to about 1,6 mm in thickness. The produced springs are exposed to corrosive effects and sometimes slightly increased temperatures. In addition to this part of ISO 6931, the general technical delivery requirements of ISO 404 are applicable. Annex A gives additional…
Surface active agents — Soaps — Determination of low contents of free glycerol by molecular absorpti...
The determination is carried out in the following way: Decomposition of the soap by sulfuric acid and extraction of the fatty acida with light petroleum. Oxidation of the free glycerol remaining in the aqueous phase by periodic acid to formic acid and formaldehyde. On reaction with chromotropic acid, the aldehyde formed gives an absorbing compound whose absorbance is propotional to the free…
Timber structures — Testing of joints made with mechanical fasteners — Requirements for wood density
Two methods for the selection of the density of wood for specimens to be used in determining strength and stiffness properties are specified, which are equally applicable. It is assumed that the wood density is normally distributed with a coefficient of variation of about 0.15 and that the density is only one of the properties influencing the strength of a joint. The other relevant properties, e.…
