Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard was proposed and managed by the National Certification and Accreditation Administration Committee.

Drafting organizations of this standard. China National Accreditation Center for Conformity Assessment, China Academy of Building Research, Shanghai Academy of Building Research (collectively Group) Co., Ltd., School of Materials Science and Engineering, Tongji University, Beijing Institute of Construction Engineering Co., Ltd., Jiangsu Transportation Research Institute Research Institute Co., Ltd., Shenzhen Academy of Building Research Co., Ltd.

Introduction

The purpose of this standard is to guide the evaluation of the technical capabilities of testing institutions in the field of building materials, standardize the evaluation process, and ensure the fairness and accuracy of the evaluation results Improve the efficiency of evaluation work at the same time.

This standard is based on GB/T 27025 and related testing standards, combined with the actual evaluation of the technical capabilities of testing institutions in the building materials field.

The refinement of related work. This standard mainly includes cementitious materials, concrete and mortar materials, metal materials, masonry materials, waterproof materials, Decoration materials, bonding and sealing materials, thermal insulation systems and materials, pipe network materials, wooden materials, curtain wall doors and windows and materials, concrete products, anti-corrosion materials, the focus of technical capability evaluation of geotechnical materials, traffic highway materials, and materials for hazardous substances. Concerns about the evaluation of technical capabilities of other building materials You can also refer to the relevant requirements of this standard.

This standard is not to be used as a basis for independent judgment of whether the testing organization meets the requirements of relevant laws, regulations and standards.
