The revision of the Tentative Criteria for Acceptance of Concrete, its com pressive strength, in harbour engineering project is reported, the practicality of the new article is examined theoretically by equiprobability of defined indexes for acceptance/rejection. According to the concrete strength data of more than two hundred projects in harbour engineering, a comparison is made by statistic analysis and sampling characteristic curves for an appropriate practicality between the corresponding articles formulated in the National Standard (GBJ10-65), the Ministry Tentative Criterion(1978), and the revised Criterion in question. It is concluded that the revised article is appropriate to the present engineering practice, and moreover, the safety of engineering quality is better managed.
