ISO/IEC 17025质量标准由国际标准化组织（ISO）和国际电工委员会（IEC）创立。它定义了对实验室的要求，以确保执行的测试和校准的质量、可靠性和可重复性。除了可溯源至美国国家标准与技术研究院（NIST）外，MN1000系列还通过了ISO/IEC 17025认可的计量实验室的认证。因此，它们符合ISO/IEC 17025规定的仪器校准的强制性标准，符合现有的最高国际计量标准。

AM公司介绍：




Applied Microspheres（埃德微）成立于 2011 年，位于荷兰莱顿市的中心，是 Distrilab Particle Technology 的关系企业。30 多年来，Distrilab 一直是欧洲粒子检测相关产品的主要供应商。
由于特定颗粒的产品的需求不断增长，以及多年来获得的丰富经验和专业知识，Applied Microspheres（埃德微）在德国美因茨建立了研究和生产中心。在过去的几十年中，使用可追溯到美国国家标准与技术研究院 (NIST) 标准的参考材料来验证和校准颗粒尺寸测量和颗粒计数仪器已成为普遍做法。随着对根据更多国际标准化程序 (ISO) 进行仪器校准和验证的需求不断增加，Applied Microspheres 开发了粒径标准和计数标准粒子，它们不仅可追溯至NIST，而且可追溯至 ISO 17025 认可实验室认证的参考材料。



Over and above traceability to the National Institute of Standards and Technology of the USA (NIST), the NanoStandard™ 17025 and MicroStandard™ 17025 size standards by Applied Microspheres are certified by an ISO/IEC 17025 accredited metrology laboratory. They therefore meet the criteria obligatory for instrument calibration under ISO/IEC 17025 and as such meet the highest international metrological standard available.

NIST traceability is typically established by an unbroken chain of measurements, referencing particles to SRMs from NIST. As such, this is basically an internal method, relying on one’s own expertise and instrumentation, whereas the NanoStandard™ 17025 and MicroStandard™ 17025 size standards consists of material from the original batches certified by the Danish National Metrology Institute (DFM).

The DFM used Atomic Force Microscopy (AFM) measurements performed under DANAK accreditation no. 255, following DS/EN ISO/IEC 17025. DANAK (Danish Accreditation and Metrology Fund) is one of the signatories to the EA multilateral agreement and the ILAC multilateral agreement for the mutual recognition of calibration certificates.

ISO/IEC 17025 is a quality standard,  founded  by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). It is the definition of requirements for laboratories to ensure quality, reliability and repeatability of performed tests and calibrations.

The calibration method and certificate thus created ensures that Applied Microspheres’ NanoStandard™ 17025 and MicroStandard™ 17025 particle size standards are traceable to the International System of Units (SI), including NIST, and meet the criteria obligatory for instrument calibration under ISO/IEC 17025. They therefore meet the highest international metrological standard available.
