This specification applies to the design, construction, use, and management of direct-insert plate-and-pin formwork scaffolding in construction projects.
This standard applies to the assessment of the fire safety system and operation of high-risk fire units within Shandong Province by fire safety assessment agencies, as well as the self-assessment of fire safety by high-risk fire units. Other key fire safety units may refer to and implement this standard accordingly.
This standard applies to the preparation of safety operation procedures for positions in units engaged in the production, storage, use, operation, and transportation of hazardous chemicals (hereinafter referred to as "hazardous chemical units"). Other positions involved in the handling of hazardous chemicals may refer to these guidelines for implementation.
This procedure is applicable to the detection of the shear strength of masonry and the strength of masonry mortar using the core drilling method.
This procedure is applicable to the testing of the compressive strength of masonry mortar using the local compression method with mortar specimens.
This procedure is applicable to the detection of the compressive strength of structural concrete using the core drilling method. When there are a large number of components to be tested, the rebound method, the ultrasonic rebound comprehensive method, the post-installation pull-out method, etc. are used in combination with the core drilling method to form the core drilling correction method. The results of the core drilling method are used to correct the results obtained by other detection methods, making the detection results more reliable and reducing the damage to the structure.
This procedure is applicable to the detection of the compressive strength of masonry mortar using the rebound method.
This standard is applicable to the detection of the compressive strength of structural concrete using the rebound method.
This standard is applicable to the detection of the compressive strength of structural concrete using the post-installation pull-out method.
This standard is applicable to the detection of the compressive strength of structural concrete using the post-anchoring method.
This procedure is applicable to the detection of the compressive strength of masonry mortar using the penetration method.
This standard specifies the terms and definitions for testing the compressive strength of concrete using the ultrasonic rebound method, the technical requirements for rebound testers, the technical requirements for concrete ultrasonic detectors, testing techniques, strength curves, and the analysis and processing of testing data. This standard is applicable to the testing of the compressive strength of concrete using the ultrasonic rebound method.
