Anotace textu normy ASTM C1208/C1208M-18(2022) :
This specification establishes the criteria for the manufacture, quality assurance testing, inspection, installation, field acceptance testing, inspection, installation, field acceptance testing, and product marking of vitrified clay pipe to be used in microtunneling, pilot tube microtunneling, sliplining, pipe bursting, and in casings and tunnels for the conveyance of sewage, industrial wastes, and storm water. Vitrified clay pipe shall be manufactured from fire clay, shale, surface clay, or a combination of these materials that, when formed into pipe and fired to suitable temperatures, yields a product that conforms to this specification. Pipes of nominal diameters shall meet the prescribed bearing strength requirements. The clay pipe shall undergo the following tests: compressive strength test; hydrostatic pressure test; absorption test; and acid resistance test. The pipe shall conform to the required sizes and dimensions. The pipe shall not deviate from straight by more than a specified value when the maximum offset is measured from the concave side of the pipe. The pipe wall thickness shall be a suitable dimension to adequately distribute the field jacking forces. There shall be no fractures or cracks passing through the carrel, visible to the unaided eye. Chips, fractures, or blisters on the pipe shall not exceed a specified value in any surface dimension and shall not exceed a required depth of the minimum thickness of the barrel. Principles of joint design, test requirements, and test methods for assembled joints shall also be indicated.

1.1?This specification establishes the criteria for the manufacture, quality assurance testing, inspection, installation, field acceptance testing, and product marking of vitrified clay jacking pipe to be used in microtunneling, the pilot tube method, sliplining, pipe bursting, and in casings and tunnels for the conveyance of sewage, industrial wastes, and storm water. 1.1.1?Sections 3 through 7 and 9 of this specification contain manufacturing, quality assurance testing, inspection, and product marking criteria which are applicable to vitrified clay pipe prior to installation. 1.1.2?Section 8 of this specification contains criteria for the installation and field acceptance testing of vitrified clay pipe. 1.2?This specification also covers materials and test requirements for jointing of the pipe. 1.3?The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.4?This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
