NOTE 2: For the purposes of this European Standard the term 'combustible gas' includes combustible vapours but excludes mist and dust, see 3.3 note 1. This European Standard is applicable to combustible gas detection apparatus intended to provide an indication) alarm and/or other output function, the purpose of which is to give a warning of potential explosion hazard and in some cases to initiate automatic or manual protective actions. This European Standard is applicable to apparatus, including the integral sampling systems of aspirated apparatus intended to be used for commercial and industrial safety applications. This European Standard does not apply to external sampling systems, or to apparatus of the laboratory or scientific types, or to apparatus used only for process control purposes

この記事では、EN 50054:1998のヨーロッパ標準について説明されています。この標準は、可燃性ガスの検出と測定のための電気機器に関する一般的な要件と試験方法を定め、可携式、可搬式、固定式の機器に適用されます。これらの機器またはその一部は、潜在的に爆発性のある環境や火食感受性のある鉱山での使用を想定しています。このヨーロッパ標準は、異なるタイプの機器の性能要件に関する以下のヨーロッパ標準によって補完されます：EN 50055：空気中のメタン濃度の5％（体積比）までを示すグループI機器の性能要件；EN 50056：100％（体積比）のメタンを示すグループI機器の性能要件；EN 50057：100％の下部爆発限界を示すグループII機器の性能要件；EN 50058：100％（体積比）のガスを示すグループII機器の性能要件。メタンを示すグループI機器やガスを示すグループII機器は、それらがキャリブレーションされた特定のガスとしか使用できないことに注意してください。このヨーロッパ標準では、「可燃性ガス」という用語は可燃性蒸気を含みますが、ミストや粉塵は除外されることになっています。このヨーロッパ標準は、潜在的な爆発の危険を警告し、必要に応じて自動的または手動で保護措置を開始するための警報および/またはその他の出力機能を提供する可燃性ガス検知装置に適用されます。また、商業および産業の安全対策に使用するための装置にも適用されますが、外部サンプリングシステムや研究室や科学目的の装置、またはプロセス制御用途のみに使用される装置には適用されません。

This article discusses the EN 50054:1998 European Standard, which specifies the general requirements and test methods for electrical apparatus used to detect and measure combustible gases. The standard applies to portable, transportable, and fixed apparatus that are intended to be used in potentially explosive atmospheres and in mines susceptible to firedamp. The article mentions that this standard is supplemented by other European Standards that provide specific requirements for different types of apparatus based on their performance capabilities. The purpose of the apparatus is to detect and measure concentrations of combustible gas or vapor in the air, and it is designed to provide warnings of potential explosion hazards and initiate protective actions if necessary. The standard applies to commercial and industrial safety applications but does not cover external sampling systems or apparatus used for laboratory or scientific purposes or process control.
