1.1 This document defines requirements and tests which apply to:- collecting heads with a nominal pressure of 16 bar (1,6 MPa) PN16 which are used by fire and rescue services to combine two or more inlets into one or more outlets;- dividing breechings with a nominal pressure of 16 bar (1,6 MPa) PN 16 which are used by fire and rescue services to divide one or more inlets into two or more outlets.NOTE 1 In this document "ColDiv" is used to refer both to collecting heads and dividing breechings.NOTE 2 In this document, drawings of collecting heads and dividing breechings are shown inlets downwards and outlet upwards.1.2 This document is not applicable to collecting heads or dividing breechings which have been manufactured before its date of publication as a European Standard.

This document gives details for the classification of gas appliances according to the method of supplying combustion air and of evacuating the combustion products (types). This classification refers to gas appliances that are intended to be installed within buildings and/or outside of the building .The document classifies appliances as type A, B or C according to the basic principle for the evacuation of the combustion products and air inlet.This document is the reference for the harmonization of product standards, for the preparation of installation standards and for the common understanding of the types of gas appliances.This document is neither an installation standard nor a product standard.In references to a gas appliance or gas appliances connected via “its” or “their” duct or ducts, it is intended that the air inlet duct and/or the discharge duct for carrying any combustion products are part of the gas appliance. This means that such ducts are certified together with the gas appliance. Informative Annex C identifies appliance types that are designed for connection to separate chimney products, which may be part of the construction of the building.In terms of this document, a "single duct" is a flue duct designed and capable of discharging the combustion products and/or air inlet duct for the air supply for only one appliance.In terms of this document, a "common duct" is a flue duct designed and capable of discharging the combustion products and/or air inlet duct for the air supply for more than one appliance.

ISO/TS 35105:2018 provides recommendations for material selection, manufacturing and fabrication requirements, testing and qualification of steel structures and components for offshore and onshore petroleum and natural gas facilities operating in Arctic and cold environments.ISO/TS 35105:2018 is intended to be used as a supplement to existing standards for steel structures where the particular operating conditions in Arctic regions are not sufficiently addressed.ISO/TS 35105:2018 gives particular requirements to ensure safe operation with respect to the risk of brittle fracture at low temperatures. These requirements will affect the selection of material grade and design class as well as the technical delivery conditions for steel. They will also affect the fabrication requirements as well as testing and qualification requirements.ISO/TS 35105:2018 also gives recommendations:- to mitigate the operational and integrity aspects related to snow and ice accretion on topside structures;- to take into account the particular Arctic operating conditions in corrosion assessments and requirements for corrosion protection systems;- for particular operational requirements to ensure safe operation in Arctic regions.The requirements in this document are applicable to any operating temperatures, but particular requirements related to de-rating (loss of strength) at high temperatures are not addressed. Limitations to the applicable minimum design temperature caused by the capability of the materials' low temperature performance can exist, but are not a limitation for the scope of this document.As a practical guideline for the use of this document, low temperature is defined as lowest anticipated service temperature (LAST) below ?10 °C.NOTE For determination of LAST, see 6.3.2.

This document specifies a method for the objective determination of the odour concentration of a gaseous sample using dynamic olfactometry with human assessors. The standard also specifies a method for the determination of the emission rate of odours from stationary sources, in particular:- point sources (conveyed or ducted emissions);- active area sources (e.g. biofilters);- passive sources.The primary application of this standard is to provide a common basis for evaluation of odour emissions.When this document is used for the determination of the odour concentration or the odour emission rate of stationary source emissions, the other relevant European Standards concerning stationary source emissions apply, in particular EN 15259 and EN 16911-1, especially when measurements have to be in compliance with the relevant European Directives concerning industrial air emissions.Even so, the analysis/quantification step of the measurement method described in this document (i.e. the determination of the odour concentration of an odorous gas sample, without respect to the origin of the sample itself) can be fully applied in many cases not related with industrial emission sources (e.g. the measurement of the mass concentration at the detection threshold of pure odorous substances, the determination of effectiveness of deodorizing systems for indoor air). In those latter cases, the requirements in this document concerning the measurement planning and the sampling of stationary sources can be ignored or adapted.This document is applicable to the measurement of odour concentration of pure substances, defined odorant compounds and undefined mixtures of odorant volatiles in air or nitrogen, using dynamic olfactometry with a panel of human assessors being the sensor. The unit of measurement is the European odour unit per cubic metre: ouE/m3. The odour concentration is measured by determining the dilution factor required to reach the detection threshold. The odour concentration at the detection threshold is by definition 1 ouE/m3. The odour concentration is then expressed in terms of multiples of the detection threshold. The range of measurement is typically from 101 ouE/m3 to 107 ouE/m3 (including pre dilution).The field of application of this document includes:- the measurement of the mass concentration at the detection threshold of pure odorous substances in g/m3;- the determination of the EROM value of odorants, in mol;- the measurement of the odour concentration of mixtures of odorants in ouE/m3; - the measurement of the emission rate of odorous emissions from point sources, active area sources and passive area sources, including pre dilution during sampling;- the sampling of odorous gases from emissions of high humidity and temperature (up to 200 °C);- the determination of effectiveness of end-of-pipe mitigation techniques used to reduce odour emissions.The determination of odour emissions requires measurement of gas velocityto determine the gas volume flow rate.The field of application of this document does not include:- the measurement of odours potentially released by particles of odorous solids or droplets of odorous fluids suspended in emissions;- the measuring strategy to be applied in case of variable emission rates;- the measurement of the relationship between odour stimulus and assessor response above detection threshold (perceived intensity);- measurement of hedonic tone (or (un)pleasantness) or assessment of annoyance potential;- direct measurement of odour exposure in ambient air. For this measurement purpose, field panel methods exist which are the subject of CEN standard EN 16841-1, Ambient Air - Determination of odour in ambient air by using field inspection - Grid method;- direct olfactometry, including field olfactometry;- static olfactometry;- measurement of odour recognition thresholds;- measurement of odour identification thresholds......
