압력용기 PED 를 적용한 밸브 CE 마킹 시 진행하는 test 방법

※    금번 뉴스레터 에서는 압력용기지침 (Pressure equipment directive: 97/23/EC) 를 적용한 압력기기의 CE 마킹 진행시 EN 12266-1에 따른 버터 플라이 밸브 (아래 사진 참조)의 최종 test 내용에 대해서 정리해보았습니다. ※    추후 타 밸브의 최종 검수 시에도 유사한 기준, 방법이 적용되므로 참조 부탁드립니다. ※    버터 플라이 밸브 예시 사진.<img src="https://t1.daumcdn.net/cfile/cafe/213E903F55690B5C30" class="txc-image" width="123" height="139" style="width: 123px;
