RB/T 145-2018Guidance on the proficiency testing of strength for concrete structure (English PDF)

Foreword

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

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

This standard was drafted. China National Accreditation Center for Conformity Assessment, China Academy of Building Research, Ministry of Transport, Highway Science Research Research institute.

Introduction

With the rapid development of China's economy and society, the number of construction projects is increasing, and the inspection and inspection of the strength of concrete structures is increasing year by year.

The concrete strength of concrete structure directly affects the quality and safety of construction engineering, and the technology of physical strength inspection and inspection mechanism for concrete structures the ability is increasingly valued by industry authorities and the attention of the society. As a kind of conformity assessment activity, proficiency testing has gradually become a line the competent authority, the accreditation body, and the users of the inspection and test results are important means for the evaluation of the technical capabilities of the inspection and testing institutions.

GB/T 27043-2012 specifies the general requirements for proficiency testing providers' capabilities, establishment and operational proficiency testing schemes, applicable Organization and management of proficiency testing in all areas of inspection and testing. This standard is based on GB/T 27043-2012, combined with concrete knots the characteristics and requirements of the field of physical strength testing and testing, and provide guidance for the implementation of the proficiency testing activities, which can help regulate the field the organization and implementation of the verification plan.

This standard does not cover the content of management requirements for proficiency testing providers. For related content, please refer to GB/T 27043-2012.

Concrete structure physical strength ability verification implementation guide

1 Scope
