Liquid hydrocarbons — Volumetric measurement by turbine flowmeter
ISO 2715:2017 describes and discusses the characteristics of turbine flowmeters. Attention is given to the factors to be considered in the application of turbine meters to liquid metering. These include the properties and nature of the liquid to be metered, the correct installation and operation of the meter, environmental effects, and the wide choice of secondary and ancillary equipment. Aspects…
Plastics — Epoxy resins — Determination of degree of crosslinking of crosslinked epoxy resins by Fou...
ISO 20368:2017 specifies a method for determining the degree of crosslinking of crosslinked epoxy resins by the disappearance of the epoxy group during epoxy resin crosslinking measured by Fourier Transform Infrared (FTIR) (with a transmittance mode) spectroscopy.
Hydrocarbures liquides — Mesurage volumétrique au moyen de compteurs à turbine
Le présent document décrit et analyse les caractéristiques des compteurs à turbine (plutôt que le terme «mesureur», généralement utilisé en français dans un tel contexte, il a été retenu le terme «compteur», en cohérence avec le titre de la présente norme). Il analyse les facteurs à prendre en considération lors de l'utilisation de compteurs à turbine au mesurage de liquides. Cette analyse…
Information technology — Security techniques — Key management — Part 4: Mechanisms based on weak sec...
ISO/IEC 11770-4:2017 defines key establishment mechanisms based on weak secrets, i.e. secrets that can be readily memorized by a human, and hence, secrets that will be chosen from a relatively small set of possibilities. It specifies cryptographic techniques specifically designed to establish one or more secret keys based on a weak secret derived from a memorized password, while preventing…
Anodizing of aluminium and its alloys — Specification for hard anodic oxidation coatings on aluminiu...
ISO 10074:2017 specifies requirements for hard anodic oxidation coatings on aluminium and its alloys, including test methods.
It also specifies the information to be supplied by the customer to the anodizer (see Annex A).
It is not applicable to coatings produced by processes such as those referred to as plasma electrolytic oxidation, micro-arc oxidation, plasma-chemical anodic oxidation, anodic…
Cinematography — Manufacturer-printed, latent image identification on 16 mm, 35 mm and 65 mm motion-...
1.1 ISO 12222:2017 specifies the position and dimensions of machine-readable identification numbers on 16 mm, 35 mm and 65 mm motion-picture film. These numbers are intended to be a machine-readable version of the latent image key number. ISO 12222:2017 also specifies the encoding format to be used for these machine-readable numbers, as well as the area scanned and the spectral characteristics…
