The quality control of anchor product was very important for concrete structure anchorage. On the basis of introducing the revision background and significance of the standard, the test content recently added and revised, the product evaluation criteria and its relationship with current domestic and foreign related standards, the key contents and the new characteristic of the new standard were introduced.
