This part of ISO 19901 specifies the SIM process engineering requirements and recommendations to be used by an owner for demonstrating the structural fitness-for-service of existing platforms operating offshore. This part of ISO 19901 addresses the platform life-cycle from concept through to decommissioning and/or possible reuse at a different location and is applicable to:? substructure structural components on compliant bottom founded structures, including fixed platforms, compliant towers, manifolds and structures used offshore as part of an alternative energy concept;? topsides structural components irrespective of the structural form, including floating facilities and jack-ups.

This European Standard specifies the general requirements and the constructional and operating characteristics relating to safety and, rational use of energy, marking, withand the associated test methods for gas heated commercial catering and bakery appliances intended to be used indoor.The specific requirements are given in Part 2.Only appliances of types A1, A2, A3, B1 and B2, as defined in Clause 4, are considered in this European Standard.This European Standard applies to all professional cooking and bakery appliances using gas for preparing food and drink.Only the net calorific value (Hi) and net Wobbe number (Wi) are used.Annex C, informative, lists the main types of equipment entering into the field of application of this European Standard.NOTE: For appliances intended to be used in vehicles, in carriages or on board ships, additional requirements may be necessary

Shall be according to EN 203 1:2019, 4 with the following addition:This European Standard applies to open burners, non-enclosed covered burners and wok burners.

This document specifies the requirements and tests for the construction, performance, safety and conformity of gas volume electronic conversion devices associated to gas meters, used to measure volumes of fuel gases of the 1st and 2nd families according to EN 437.This document is intended for type testing, the detailed relevant provisions of which are given in Annex A.Only three kinds of conversion are treated in this document:- conversion as a function of temperature only (called T conversion);- conversion as a function of the pressure and of the temperature with constant compression factor (called PT conversion);- conversion as a function of the pressure, the temperature and taking into account the compression factor (called PTZ conversion).This document is not relevant to temperature conversion integrated into gas meters which only indicate the converted volume.EN 12405-2 applies for energy conversion.Gas-volume conversion devices consist of a calculator and a temperature transducer or a calculator, a temperature transducer and a pressure transducer locally installed.For application of this document, a conversion device may be, as a choice of the manufacturer, considered as a complete instrument (Type 1) or made of separate elements (Type 2), according to the definitions given in 3.1.18.1 and 3.1.18.2.In this last case, the provisions concerning pressure transducers, temperature sensors and temperature transducers are given in Annexes B, C and D respectively.Any conversion device can provide an error curve correction for a gas meter.NOTE When rendering an account to an end user the readings from the conversion device can be used in conjunction with the readings from a gas meter conforming to EN 1359, EN 12480, or EN 12261, as appropriate, or to any other appropriate and relevant international or national standard for gas meters, without prejudice of national regulations.

This document specifies requirements and gives recommendations for the design, installation, inspection and maintenance of fixed land based water mist systems.This document is intended to apply to water mist automatic nozzle systems and water mist deluge systems supplied by stand alone or pumped systems.The document covers only applications and occupancies which are covered by relevant fire test protocols.Aspects of water mist associated with explosion protection and/or vehicles are not covered by this document.This document does not cover all legislative requirements. In certain countries specific national regulations apply and take precedence over this document. Users of this document are advised to inform themselves of the applicability or non-applicability for this document by their national responsible authorities.
