Acceptance conditions for radial drilling machines with the arm adjustable in height — Testing of ac...
This second edition cancels and replaces the first edition (i. e. ISO 2423 : 1974). Describes both geometrical and pratical tests on these general purpose and normal accurasy radial drilling machines, and gives the corresponding permissible deviations which apply. Deals only with the verification of the accuracy of the machine. Does not apply to the testing of the running of the machine (…
Plastics — Plasticized cellulose acetate — Determination of matter extractable by diethyl ether
The determination method applies to plasticized cellulose acetate in any form, such as moulding material, sheet, manufactured articles. Conversion of the plastizised sample to a film, prepared by dissolving and casting, and subsequent extraction by ethylether in a Soxhlet apparatus. Removal of the ether by heating under vacuum and weighing the residual matter.
Building construction — Modular coordination — Modular floor plane for vertical dimensions
Defines three positions of the modular floor plane as reference plane for vertical modular dimensions in building design and gives rules for the position of the floor in relation to this plane. Applies to the construction of buildings of all types designed in accordance with the principles and rules of modular coordination as laid down in ISO 2848.
Conditions de réception des machines à percer radiales à bras mobile en hauteur — Contrôle de la pré...
La présente Norme internationale indique, par référence à l'ISO/R 230, les vérifications géométriques et les épreuves pratiques des machines à percer radiales à bras mobile en hauteur, ainsi que les écarts tolérés correspondant à des machines d'usage général et de précision normale. Elle ne traite que du contrôle de la précision de la machine. Elle ne concerne ni l'examen de son…
Petroleum waxes and petrolatums — Determination of drop melting point
May be used to measure the melting acharacteristics of petrolatums and other high viscosity petroleum waxes. Additional methods used are given in ISO 3841 and ISO 2207. Results obtained may differ, depending on the method used. For pharmaceutical petrolatum, the use of this procedure is usually preferred. In the annex, the specification for thermometers is given.
