IEC 61188-6-2:2021 describes the requirements of design and use for soldering surfaces of land pattern on circuit boards. This document includes land pattern for surface mounted components. These requirements are based on the solder joint requirements of IEC 61191‑2:2017.

L’IEC 61188-6-2:2021 décrit les exigences de conception et d’utilisation relatives aux surfaces de brasage de la zone de report sur les cartes imprimées. Le présent document porte notamment sur la zone de report des composants montés en surface. Ces exigences se fondent sur les exigences relatives aux joints de brasure de l’IEC 61191-2:2017.

IEC TR 63335:2021 identifies a number of issues of particular importance to light water Small Modular Reactors (SMRs), which are not currently adequately addressed by existing IEC SC 45A standards, and that could be considered when revising existing publications or that could be the object of new work item proposals. Whether each of these issues will indeed be addressed, and if so in which…

Le présent document spécifie la détermination quantitative par chromatographie en phase liquide de certains sucres (galactose, glucose, fructose, saccharose, lactose et maltose) dans divers laits et produits laitiers, en utilisant l'arabinose comme étalon interne. Cette méthode s'applique aux matrices laitières suivantes: lait, lait concentré sucré, lait en poudre, fromage, lactosérum…

The document specifies test conditions for determining the seasonal performance characteristics of air source heat pump water heaters for space heating with electrically driven compressors with or without supplementary heater. The purpose of this document is to rate performance of the heat pump water heaters for space heating with no operation of any supplementary heater. In the case of heat pump…

This document specifies the quantitative liquid chromatographic determination of specific sugars (galactose, glucose, fructose, sucrose, lactose and maltose) in various milk and milk products, applying arabinose as an internal standard. The method is applicable to the following dairy matrices: milk, sweetened condensed milk, milk powder, cheese, whey powder, infant formula, milk dessert and…

This document defines terms relating to rattan source plants, materials, intermediate rattan products and rattan products. This document is applicable to rattan materials and products in production and trade.

Le présent document spécifie une méthode de quantification de quatre nitrosamines spécifiques du tabac (TSNAs) dans la matière particulaire totale du courant principal de la fumée de cigarette par chromatographie liquide haute performance en phase inverse avec détection par spectrométrie de masse en tandem (CL-SM/SM). Les TSNAs quantifiées sont les suivantes: N-nitrosonornicotine (NNN), N‑…

This document specifies a method for the quantification of four tobacco specific nitrosamines (TSNAs) in tobacco and the following tobacco products: cigarettes, cigars and smokeless tobacco products using reversed phase high performance liquid chromatography with tandem mass spectrometry (LC-MS/MS). The TSNAs determined with this method are: N-nitrosonornicotine (NNN), N-nitrosoanatabine (NAT), N…

This document specifies a method for the quantification of four tobacco specific nitrosamines (TSNAs) in the total particulate matter of mainstream cigarette smoke by using reversed phase high performance liquid chromatography with tandem mass spectrometry (LC-MS/MS). The quantified TSNAs are: N-nitrosonornicotine (NNN), N-nitrosoanatabine (NAT), N-nitrosoanabasine (NAB) and 4-(methylnitrosamino…
