BS 7967:2015 用于测量住宅内一氧化碳和家用燃气器具燃烧性能的便携式电子燃烧气体分析仪使用指南

1.1This standard provides guidance for gas operatives on: a)the general use of an electronic portable combustion gas analyser conforming to BS EN 50379-3 and BS 7927:1998 incorporating Amendment No.1:1999; NOTE 1 This standard assumes that a portable combustion gas analyser [often referred to colloquially as a "flue gas analyser" (FGA)J of the type specified in BS EN 50379-3 or BS 7927:1998 incorporating Amendment No. 1:1999 is available to the gas operative and the operative is competent in its use and the interpretation of any reading obtained. This competence can be demonstrated by satisfactory completion of the relevant ACS assessments,which cover the use of electronic portable combustion gas analysers. See Clause 4 for further information on competence. NOTE 2 BS EN 50379-3 superseded BS 7927:1998 incorporating Amendment No. 1:1999 on I March 2007. However,electronic portable combustion gas analysers conforming to BS 7927:1998 incorporating Amendment No. 1:1999 remain acceptable for the purposes of this standard. b)the use of such an electronic portable combustion gas analyser to determine ambient levels of carbon monoxide (CO) and, in certain circumstances (see Notes 4 and 5, and Commentary on 8.1), detect the presence of carbon dioxide (CO) in dwellings; NOTE 3 A definition of a dwelling is given in 3.7. NOTE 4 One of the main combustion products from gas appliances is CO, which is mainly regarded as an asphyxiant, but is also a toxic substancc which could be present in the air in sufficient quantity to prove harmful. For guidance on the occupational health considerations of CO, reference can be made to the HSE Guidance note on Workplace exposure limits,EH4012005 [8]. NOTE 5 Electronic portable combustion gas analysers that calculate CO levels from an oxygen (O) measurement are: ?well proven for calculating CO levels in combustion gases in the flue of an appliance; ?not suitable for measuring ambient levels of CO in dwellings; and ?able to detect increases in the ambient CO levels in ambient atmospheres and such increases in CO will provide an early indication of increasing build-up of products of combustion in the room (see Commentary on 8.1). c)the use of an electronic portable combustion gas analyser to measure CO and CO in combustion products from the following types of gas-fired appliances: 1)flueless appliances (type A appliances); 2)open-flue appliances (type B appliances); 3)room-sealed appliances (type C appliances); and 4)all appliances for which the gas appliance manufacturer has provided a purpose-designed sampling point or specific sampling instructions; NOTE 6 Type A, type B and type C classification of gas-fired appliances is described in PD CENITR 1749 and in 3.21. d)the use of an electronic portable combustion gas analyser as a diagnostic instrument to assist a gas operative: 1)in confirming safe and/or efficient operation at the time of commissioning, in accordance with gas appliance instructions; 2)in determining the level of servicing required for a gas-fired appliance;

Guide for the use of electronic portable combustion gas analysers for the measurement of carbon monoxide in dwellings and the combustion performance of domestic gas-fired appliances

BS 7967-5:2010 住宅和其它楼宇中一氧化碳及燃气设施的燃烧性能.第5部分: 非住宅楼宇中采用便携式电子燃烧气体分析仪测量一氧化碳和二氧化碳及测定燃烧性能的指南

This standard gives guidance for identifying and investigating spillage, leakage or build‑up of combustion products from gas-fired appliances in non-domestic premises. It gives recommendations for determining the combustion performance of such equipment, using electronic portable combustion gas analysers. This involves sampling and measuring the carbon monoxide (CO) and carbon dioxide (CO) in the ambient air and in gas-fired appliance chimneys. This standard is for use with equipment using 1st, 2nd or 3rd family gases. NOTE 1 An operative attending non-domestic premises might be required to examine standard gas-fired appliances which are domestic or commercial as well as customized process plant/equipment. NOTE 2 This standard does not cover the response of an emergency service provider (ESP) to a gas emergency. It also does not cover procedures for investigating incidents that are reportable under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 1995 (RIDDOR) and the Gas Safety (Management) Regulations 1996 (GSMR). NOTE 3 Combustion products from gas-fired appliances contain aldehydes and oxides of nitrogen (NOx), predominantly nitrogen monoxide (nitric oxide, NO) and nitrogen dioxide (NO). Although this standard does not cover the measurement of these substances, quantities of such products could be present in the air and could cause harm and irritation to humans. For guidance on the health considerations associated with these combustion products, see the Institute for Environment and Health assessment, Indoor air quality in the home: Nitrogen dioxide, formaldehyde, volatile organic compounds, house dust mites, fungi and bacteria.

Carbon monoxide in dwellings and other premises and the combustion performance of gas-fired appliances.Part 5: Guide for using electronic portable combustion gas analysers in non-domestic premises for the measurement of carbon monoxide and carbon dioxid

BS 7967-4:2007 住所一氧化碳和燃气设施的燃烧性能.作为燃气设施维修过程的一部分和燃气设施维护的便携式电子燃气分析仪使用指南

This part of BS 7967 gives guidance on the use of an electronic portable combustion gas analyser as a diagnostic instrument to assist a gas operative: a) in determining the level of servicing required for a gas-fired appliance; b) in confirming satisfactory combustion following servicing in accordance with manufacturer’s instructions; c) in confirming satisfactory combustion following maintenance. This standard is intended to ensure the safe and efficient operation, in dwellings, of: 1) flueless gas-fired appliances (type A gas-fired appliances), e.g. cooking appliances, space heaters. 2) open flued appliances (type B gas-fired appliances). 3) room sealed appliances (type C gas-fired appliances). NOTE 1 Types A, B and C classifications of gas-fired appliances are described in PD CEN/TR 1749. This standard is for use with appliances using 1st, 2nd or 3rd family gases. This standard deals with the measurement of carbon monoxide (CO), the determination of carbon dioxide (CO2) and their ratio in combustion products from gas-fired appliances. NOTE 2 This standard does not cover the use of an analyser during commissioning. However, an appliance manufacturer may specify the need for a combustion test during commissioning. If this is called for, and if either due to the absence of the necessary equipment or through lack of expertise, the manufacturer’s methods and figures cannot be applied, the appliance needs to be turned off, disconnected and labelled as an uncommissioned appliance until such time as either the necessary equipment and/or expertise is available. NOTE 3 Following a landlord’s gas safety check in accordance with regulation 36(3) of The Gas Safety (Installation and Use) Regulations 1998 [1], an electronic portable combustion gas analyser can also be used in accordance with this standard as a diagnostic instrument to determine the need for further work. NOTE 4 Combustion products from gas appliances will contain nitrogen oxides (NOx), predominantly nitrogen monoxide (nitric oxide, NO) and nitrogen dioxide (NO2). This standard does not deal with the measurement of combustion products such as nitrogen oxides and aldehydes. Such products could be present in the air in sufficient quantities to prove an irritant and could be harmful. For guidance on the occupational health considerations associated with these combustion products, reference can be made to the following documents. a) The Institute for Environment and Health’s IEH assessment on indoor air quality in the home: Nitrogen dioxide, formaldehyde, volatile organic compounds, house dust mites, fungi and bacteria [7]. b) The Health and Safety Executive’s (HSE’s) Chemical Hazard Alert Notices, CHAN 28 on nitrogen monoxide [8] and CHAN 29 on nitrogen dioxide [9]. Please note that these CHANs refer to occupational levels specifically related to the workplace situation. For further guidance refer to the HSE1).
