Welded steel tubes for pressure purposes — Technical delivery conditions — Part 1: Unalloyed steel t...
Lays down the conditions for tubes of circular cross-section. These tubes are intended for pressure purposes including the transport of fluids under pressure. Includes symbols and denominations, information to be supplied by the purchaser, manufacturing process, metallurgical properties, dimensions, masses and tolerances, appearance and soundness, inspection and testing, marking and protection.
Work-place air — Determination of mass concentration of carbon monoxide — Method using detector tube...
Specifies a method for concentrations greater than 10 mg/m^3. The method is suitable for personal, breathing-zone sampling as well as for the general area sampling. Information on performance characteristics is given. In applications requiring better precision or freedom from interferences, the use of classical chemical or instrumental methods is recommended.

La présente Norme internationale prescrit une méthode pour la détermination de la concentration en masse du monoxyde de carbone présent dans l'air des lieux de travail (dans les zones de travail ou à poste fixe) aux concentrations de plus de 10 mg/m3 à l'aide de tubes détecteurs. L'article 5 indique les substances qui, si elles sont contenues dans la masse d'air examinée et…
Aerospace — Constant displacement hydraulic motors — General specifications
Establishes informations for motors to be installed in aircraft, which transform hydraulic power into mechanical energy in the form of a rotational torque. Primary and secondary function motors are covered. Actuators with internal rotation angle limits and low-speed motors are not covered. Shall be used in conjunction with the detail specification particular to each application.
