Welcome to this website, where you can query the price of ISO standards, the latest version of ISO standards and the basic introduction of ISO standards.
This document defines the general conditions for the determination of the reduced viscosity, intrinsic viscosity and K-value of organic polymers in dilute solution. It defines the standard parameters that are applied to viscosity measurement. This document is used to develop standards for measuring the viscosities in solution of individual types of polymer. It is also […]

This International Standard specifes four methods for the quantitative determination of the material extractable from raw rubbers, both natural and synthetic; two of the methods are also applicable to the unvulcanized and vulcanized compounds of raw rubbers. Method A measures the mass of the solvent extract, after evaporation of the solvent, relative to the mass

This International Standard specifies the minimum requirements for mono wall and multilayer tubing used in air braking systems on road vehicles. The conformity of production is the responsibility of the tubing manufacturer. The marking of the tubing does not automatically imply that the tube assembly (i.e. tube with end fttings) is appropriate for its use
