ISO 17943:2016 specifies a method for the determination of volatile organic compounds (see Table 1). This comprises, for example, halogenated hydrocarbons, trihalogenated methanes, gasoline components (such as BTEX, MTBE, and ETBE), naphthalene, 2-ethyl-4-methyl-1,3-dioxolane, and highly odorous substances like geosmin and 2-methylisoborneol in drinking water, ground water, surface water, and…

ISO 24505:2016 provides a method for creating conspicuous colour combinations for use in visual signs and displays taking into account viewer age. It is based on the perceived similarity of colours at photopic and mesopic lighting conditions. ISO 24505:2016 applies to the design of visual signs and displays in which multiple colours are used so that the colours are conspicuous to people of any…

ISO 18324:2016 specifies test procedures to measure natural frequencies, modal damping ratios and static deflection under a concentrated load of laboratory or field timber floors. These parameters have been found to correlate well with human perception to timber floor vibration response caused by human-induced excitation under normal use. It is intended that the test procedures can be applied in…

This is the third edition of CAN/CSA-IEC 61000-4-4, Electromagnetic compatibility (EMC) — Part 4-4: Testing and measurement techniques — Electrical fast transient/burst immunity test, which is an adoption without modification of the identically titled IEC (International Electrotechnical Commission) Standard 61000-4-4 (third edition, 2012-04). It supersedes the previous edition published in 2006…

1.1 This Standard specifies the design, installation, operation and maintenance of site-built and modular gaseous hydrogen fueling stations (HFS) for light duty vehicles, where light duty vehicles are defined by the Environmental Protection Agency as passenger cars and light trucks, minivans, passenger vans, pickup trucks, and sport-utility vehicles, also referred to as the “common category”…

IEC 62439-3:2016 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62439-3:2016 is applicable to high-availability automation networks based on the Ethernet technology. This part of…

IEC 61162-450:2011+A1:2016(E) specifies interface requirements and methods of test for high speed communication between shipboard navigation and radiocommunication equipment as well as between such systems and other ship systems that need to communicate with navigation and radio-communication equipment. Is based on the application of an appropriate suite of existing international standards to…

ISO 15753:2016 describes two methods for the determination of 15 polycyclic aromatic hydrocarbons (PAHs) in animal and vegetable fats and oils: - a general method; - a specific method for coconut oil and vegetable oils with short-chain fatty acids. These methods are not quantitative for the very volatile compounds such as naphthalene, acenaphthene and fluorene. Due to interferences…

ISO 9936:2016 specifies a method for the determination of the contents of free α-, β-, γ-, and δ-tocopherols and tocotrienols (referred to jointly as tocols) in animal and vegetable fats and oils (referred to hereinafter as fats) by high-performance liquid chromatography (HPLC). For products containing tocopherol or tocotrienol esters, it is necessary to carry out a preliminary saponification.…

IEC TR 61282-9:2016(E) which is a Technical Report, describes effects and theory of polarization mode dispersion (PMD) and provides guidance on PMD measurements. This second edition cancels and replaces the first edition published in 2006. This second edition includes the following significant technical changes with respect to the previous edition: - much of the theory has been condensed -…
