Suomen Standardisoimisliitto SFS

This European Standard specifies the safety, construction and performance requirements for electronic fuel/air ratio control system (ERC), electronic fuel/air ratio supervision system (ERS) and electronic fuel/air ratio trim system (ERT) intended for use with burners and appliances burning gaseous or liquid fuels. It also describes the test procedures for evaluating these requirements and specifies information necessary for installation and use.This European Standard is applicable to— closed loop fuel/air ratio control systems, see 3.101;— fuel/air ratio supervision systems, see 3.102;— closed loop fuel/air ratio trim systems, see 3.103;and does not differentiate into classification by heat input.NOTE 1 European Standards for burners, appliances or processes which use ERC, ERS or ERT can override the requirements of this standard.NOTE 2 Provisions for production control are not part of this European Standard.

This document specifies a titrimetric method for the determination of acid value in light coloured Fatty Acid Methyl Esters, hereinafter referred as FAME.It allows the determination of acid value within a range of 0,10 mg KOH/g to 1,00 mg KOH/g.

This document specifies minimum requirements for the design, testing and production testing of valves, including appropriate fittings, which are connected to mobile or static LPG pressure vessels above 150 l water capacity. Pressure relief valves and their ancillary equipment, contents gauges and automotive LPG components are outside the scope of this document.This document does not apply to refineries or other process plants.

This document provides a framework and establishes requirements for attribute-based unlinkable entity authentication.

This document formulates requirements for garments that support the protection against tick bites. The document applies to all types of garments where protection against tick bites, which is provided by garments as physical barriers, is reinforced by industrial treatment with the biocide permethrin prior to confectionNOTE Untreated garments covering the torso, arms and legs and feet offer some protection against tick bites but are insufficient under high exposure to ticks, which can crawl over the fabric to reach bare skin and bite. Garments that comply with this document and cover at least torso, arms and legs counter ticks from crawling over the fabric to reach bare skin and bite; such garments thereby provide substantial additional protection.

This document specifies high-level requirements for management systems for sustainable cocoa bean production, including post-harvest processes, if applicable, and traceability of the sustainably produced cocoa beans within the organization producing the cocoa beans.NOTE 1 Post-harvest processes include pod-breaking, fermentation, drying, sorting, packing, transport and storage of cocoa beans.Only organizations that fulfil both the cocoa sustainability management system requirements of either this document or ISO 34101-4:2019, Annex A or B, and the performance requirements of ISO 34101-2 can claim their cocoa beans have been sustainably produced. NOTE 2 ISO 34101-4 specifies the requirements for cocoa sustainability management systems at entry and medium levels.

This document specifies performance requirements related to economic, social and environmental aspects for sustainable cocoa bean production, including post-harvest processes, if applicable.NOTE Post-harvest processes include pod-breaking, fermentation, drying, sorting, packing, transport and storage of cocoa beans.Only organizations that fulfil both the cocoa sustainability management system requirements of either ISO 34101-1 or ISO 34101-4:2019, Annex A or B, and the performance requirements of this document can claim their cocoa beans have been sustainably produced.
