SIST EN 12921-2:2005+A1:2009 표준은 산업용 품목의 표면 청소 및 전처리를 위한 기계에 대해 규정하고 있으며, 특히 수성 세정액을 사용하는 기계의 안전성을 다루고 있습니다. 이 표준은 수성 세정액을 이용해 작업하는 청소 기계의 주요 위험 요소를 식별하고, 이러한 기계가 의도한 용도로 사용될 때 안전성을 보장하기 위해 필요한 규정을 포함하고 있습니다. 이 표준의 강점은 여러 가지입니다. 첫째, EN 12921-1과의 연계를 통해 청소 기계의 모든 주요 위험을 포괄적으로 다룬다는 점입니다. 두 표준이 함께 적용됨으로써, 수성 세정액을 사용할 때의 안전 기준이 강화됩니다. 둘째, 수성 세정액으로 인해 발생할 수 있는 인화성 증기와 관련된 안전 문제에 대해 EN 12921-3과 함께 적용할 수 있도록 명시하고 있어, 복잡한 상황에서도 일관된 안전 관리가 가능하다는 것입니다. 또한, 이 표준은 누출로 인한 폭발성 대기발생의 위험 요소를 인지하고, 할로겐화 용매 함량이 2%를 초과하는 경우의 위험성을 명확하게 정의하여 해당 조건에서 사용되는 기계의 안전성을 높이는 데 기여합니다. 이러한 특수 요구 사항은 EN 12921-1의 요구 사항보다 우선 적용되는 점에서 사용자의 안전을 최우선으로 고려하고 있음을 보여줍니다. 마지막으로, SIST EN 12921-2:2005+A1:2009 표준은 CEN이 발표하기 전에 제조된 수성 세정액을 사용하는 청소 기계에는 적용되지 않으며, 이는 구식 기계의 안전성을 보장하기 위한 기준이 아닌, 현행 기준을 준수하는 최신 기계들에 중점을 두고 있다는 점에서 안전 기준의 시대적 적합성을 인정할 수 있습니다. 이러한 모든 요소들은 SIST EN 12921-2:2005+A1:2009 표준이 산업용 기계의 안전성을 확보하는 데 중요한 역할을 수행하고 있음을 잘 보여줍니다.
