Carbonaceous materials used in the production of aluminium — Pitch for electrodes — Sampling
Specifies methods for sampling and preparing samples prior to testing of binder pitch used in the manufacture of electrodes for the electrolytic production of aluminium. These methods are applicable to grades of pitch in liquid or solid form, the latter having softening points higher than 30 °C in bulk or in a number of containers making up one batch at sites of manufacture, storage or delivery.
Tolerances for building — Part 1: Basic principles for evaluation and specification
Describes the nature of dimensional variability in building and the purposes for which it has to be quantified, and defines the factors to be taken into account in the evaluation, specification and verification of tolerances for the manufacture of building components and for site work. Applies to components and buildings generally, including those designed in accordance with the principles of…
Electrical installations for outdoor sites under heavy conditions (including open-cast mines and qua...
Applies to all installations with voltages up to and including 1 000 V as well as with those above 1 000 V. Describes protective measures intended to ensure the safety of persons from electric shock in normal service and in case of fault. Also, particular requirements applicable to TN, TT and IT system earthing. Extends the principles to the protection against overcurrent in respect of overload…
Graphical symbols for use on equipment. Index, survey and compilation of the single sheets
Establishes uniform graphical symbols, their graphic form, meaning and application. These graphical symbols are placed on equipment or parts of equipment of any kind in order to instruct the persons handling the equipment as to its use and operation; they are also placed on sites and ways where people may assemble, or move, giving them instructions, such as prohibitions, warnings, rules or limits…
