1 Foreword

CECS 03-2007 was issued by China Association for Engineering Construction Standardization on 16 April 2007.

It replaces the earlier edition CECS 03-1988.

The CECS prefix marks a association standard of the engineering construction sector, adopted voluntarily.

2 Scope

This standard applies to the structure of core drilling method for detecting the intensity of not more than ordinary concrete strength of 80MPa. Outside the drill core testing concrete strength should implement the provisions of this regulation, there should be a load current national standards.

CECS 03-2007 falls under ICS 91.080.40, in the field of construction materials and building.

This catalogue holds 144 other CECS standards in that field.
