Scope
Main technical content: This document is applicable to the detection of heat fusion joints of polyethylene pipes with an outer diameter of 100 mm to 630 mm and a standard size ratio of SDR11 to SDR17. This document is not applicable to the detection of electric fusion joints of polyethylene pipes. For other non-metallic materials and non-polar composite materials, reference can be made to the implementation, but the change of microwave dielectric constant should be taken into account
