This document describes procedures to characterize quadrupole mass spectrometers (QMSs) with an ion source of electron impact ionization and which are designed for the measurement of atomic mass-to-charge ratios m/z < 300. This document is not applicable to QMSs with other ion sources, such as chemical ionization, photo-ionization or field ionization sources and for the measurements of higher…

This Standard sets forth the minimum requirements for containment sumps, and associated sump fittings and accessories (products) intended for below- or at-grade use as an enclosure for housing of, and access to, underground piping, connector piping, and other fueling system components (such as pumps, valves, sensors, wiring, etc.) in addition to temporary containment of typical liquid fuels as…

This group safety publication is primarily intended to be used as a product safety standard for the products mentioned in the scope, but shall also be used by technical committees in the preparation of their publications for products similar to those mentioned in the scope of this standard, in accordance with the principles laid down in IEC Guide 104 and lSO/lEC Guide 51. IEC 61010-2-120:2016…

1.1 This Standard sets forth the minimum requirements for primary, secondary, and coaxial types of flexible connector pipes intended for short length transfer and containment of the specific liquid fuels (or vapours thereof) identified in this Standard, at commercial (public) or fleet (private) automotive motor vehicle fueling stations or similar fuel dispensing applications, and piping…

This document specifies a test method for atmospheric corrosion measurements, using two-electrode electrochemical sensors. It is applicable to measurements of the corrosion rate of uncoupled metal surfaces (i.e. "free" corrosion rate), galvanic corrosion rate, conductance of thin film solutions and barrier properties of organic coatings. It specifies electrochemical sensors that are…

This document specifies a bioassay for the determination of the presence of unknown toxic contaminants in test seawater (see Figure A.1). It is based on the inhibition of photosynthetic activity of the marine cyanobacterium Cyanobium sp. (NIES-981) by such toxic contaminants. The inhibition is determined based on delayed fluorescence (DF) intensity. The method is rapid and requires less…

1 Scope 1.1 This Guideline provides direction for the application of exemption quantity and clearance level criteria for the release of materials containing, or potentially containing, radioactive nuclear substances, and the activities necessary to demonstrate compliance with these criteria. Specifically, this Guideline addresses clearance of materials that are regulated by the Nuclear…

Scope 1.1 This Standard sets forth the minimum requirements for cover primary, secondary, and coaxial types of flexible connector pipes intended for short length transfer and containment of the specific flammable and combustible liquids (or vapors thereof) identified in this Standard, at commercial (public) or fleet (private) automotive motor vehicle fueling stations or similar fuel…

IEC TS 61400-25-71:2019 focus on the communications between wind power plant components such as wind turbines and actors such as SCADA systems. Non­-IEC 61850/IEC 61400-25 internal communication within wind power plant components is outside the normative scope of the IEC 61400-25 series. This document describes how to extend the IEC 61400-25 series with the IEC 61850­6 Substation Configuration…

1 Scope 1.1 These requirements cover mechanical type accessories that are typically intended for attachment to storage tanks or connecting pipe for flammable and combustible liquids in commercial (public) or private (fleet) automotive fueling station and similar storage or dispensing applications and are designed to provide automatic safety or operational functions. 1.2 These products may be…
