폴리 브롬화 디페닐 에테르류(PBDEs)는 난연제의 한 종류로서 인체와 생태계에 영향을 미치는잠재적인 독성물질이며 최근 들어 관심의 대상이 되고 있는 화학물질이다. 유럽연합을 비롯하여 많은 국가들은 전기전자제품에 이 물질의 사용을 제한하고 있다. 이와 관련된 시험소인정을 지원하기 위해 고충격 폴리스티렌(HIPS) 중 PBDE류 측정을 위한 숙련도시험을 ISO/IEC 17043을 기초로 하여 수행하였다. 고충격 폴리스티렌에 포함된 4종의 PBDE류(PBDE-154, 183, 206, 209)를 측정 대상 물질로 하여 숙련도시험이 수행되었다. 10 g의 펠렛형 고충격 폴리스티렌 시료를 35개 참가실험실들에게 배포하였고 실험실들의능력을 평가하기 위해 z-score를 사용하였다. 숙련도 시험의 결과 및 참가 실험실 평가결과를 기술하였다.
Polybrominated diphenyl ethers (PBDEs) are a class of brominated flame retardants (BFRs) which have taken much interest recently due to their potential hazardous effects to human body and ecosystem. Many countries and European community prohibits the usage of certain BFRs in electronics and electronic devices (e.g. RoHS). In this perspectives, Korea Research Institute of Standards and Science (KRISS) has designed and practiced proficiency testing programs based on the ISO/IEC 17043 in order to assist laboratory accreditation activities. The programs for interlaboratory comparisons include congeners of PBDE (PBDE-154, 183, 206,209) in high impact polystyrene (HIPS). A sample bottle that contains 10 g granular HIPS was distributed to 35 participating laboratories and the test results were calculated by the statistical procedure using z-scores to evaluate performance of each laboratory. The results and the laboratory's performance were discussed.
