Plastics — Polyurethane raw materials — Determination of isocyanate content
ISO 14896:2009 specifies two methods for the measurement of the isocyanate content of aromatic isocyanates used as polyurethane raw materials. Method A is primarily applicable to refined toluene diisocyanate (TDI), methylene-bis-(4-phenylisocyanate) (MDI) and their prepolymers. Method B is applicable to refined, crude or modified isocyanates derived from toluene diisocyanate, methylene-bis-(4-…

Paints and varnishes — Determination of percentage volume of non-volatile matter by measuring the no...
ISO 23811:2009 specifies a simple practical method for calculating the non-volatile matter by volume, NVV, of a coating material from the non-volatile-matter content, NV, the density of the coating material and the density of the solvents. Using the non-volatile matter by volume results and the density obtained in accordance with ISO 23811:2009, it is possible to calculate the theoretical…
Space systems — Electromagnetic interference (EMI) test reporting requirements
ISO 24637:2009 provides specific requirements for the content of equipment-level electromagnetic interference (EMI) test report documentation to ensure that sufficient data is provided for subsequent integration analysis of complex space systems. Emphasis is placed on necessary test report augmentation to include additional test data reporting when specifically needed to document any EMI test…
Space systems — Space environment (natural and artificial) — The Earth's ionosphere model: inte...
ISO/TS 16457:2009 provides guidance to potential users for the specification of the global distribution of ionosphere densities and temperatures, as well as the total content of electrons in the height interval from 50 km to 1 500 km. It includes and explains several options for a plasmaspheric extension of the model, embracing the geographical area between latitudes of 80°S and 80°N and…
