台灣目前工程材料品質試驗，慣以ISO/IEC 17025測試實驗室執行，經TAF認可之測試實驗室，於確保實驗室品質管理與技術能力的效果是無庸置疑的，但卻僅能對於受測樣品之特性進行確認，優點是委託者可多方自行選擇適宜之測試實驗室，缺點在於這類實驗室所出具之結果報告均僅對委託者提供之試樣負責，試驗結果代表性不足，且委託者所提供之樣品真實性則更有待商確，無法針對施工完成中及完工後對於工程材料品質進行成效結果之驗證，若能借由ISO/IEC 17020檢驗機構認證制度，建立相關認證項目，作為成效驗證之結果依據，以檢驗機構於施工前中後階段分別執行檢驗，以其檢驗結果作為業主或設計單位施工前設計成效驗證、施工單位施工中品質管制機制及工程相關單位施工後之品質保證機制，是一有效提昇技術能力及強化工程品質的具體方法，本文主要概略簡介目前國內TAF檢驗機構之發展現況及特性，並同時以運用檢驗機構於後置式化學錨栓(植筋) 檢驗為例進行探討，提供ISO/IEC 17025測試實驗室成為ISO/IEC 17020檢驗機構者之依循。;Taiwan currently follows the standards stipulated in the ISO/IEC 17025 General Requirements for the Competence of Testing Laboratories for the quality assessment of construction materials. By commissioning TAF accreditation laboratories, the level of quality control and technical competency of laboratories can be ensured. However, accreditation laboratories can only assess the properties of submitted test samples. The advantage is that contracting parties can freely select a suitable TAF accreditation laboratory. The disadvantage is that the reports provided by these accreditation laboratories are only applicable to the specimens submitted by the contracting party, and test results lack representativeness. Moreover, the authenticity of the samples provided by the contracting party is not accounted for, and therefore the quality of construction materials during and after construction cannot be assessed. Only by adopting the accreditation system of ISO/IEC 17020 inspection bodies to establish relevant accreditation items, and commissioning these inspection bodies to conduct inspections before, during, and after construction activities can technical competency and construction quality be effectively improved. Consequently, the inspection results can be used to verify the pre-construction design effectiveness of the owner or the licensed design professional, the mid-construction quality control mechanism of contractors, and the post-construction quality assurance mechanism of related construction units. The purpose of the present study was to discuss the development conditions and trends of the TAF inspection bodies in Taiwan. In addition, the effectiveness of these inspection bodies on post-installed adhesive anchors in concrete was investigated. To supply references for ISO/IEC 17025 testing Laboratories intended to upgrade to ISO/IEC 17020 inspection bodies.
