국내 FFF1의 측정값이 국가기술표준원 공인 장비인 FFF2와 다소 차이는 있지만 판매 목적의 차단율을 파악하는 데는 충분히 활용될 수 있을 것이라 판단된다.
Even though the measured value of the domestic FFF1 is slightly different from the FFF2, which is really a certified equipment by the National Institute of Technology and Standards, it is judged it may be used sufficiently to look for the blocking rate for the intended purpose of purchase.
