PROBLEM TO BE SOLVED: To provide a method for judging quality when an objective part to be jointed is jointed to a jointing face by rubbing e.g. by rotating the jointing face between the jointing part and the objective part to be jointed under a condition where the objective part to be jointed of a piping material 2 made of a resin is inserted into the jointing part provided in a joint 3 made of the resin. ;SOLUTION: A method for judging quality of a jointed article of a resin pipe/joint by judging whether two conditions where a definite amount of resin molecules of the jointing face is cut and a definite quantity of heat caused by friction is accumulated in the joint and the piping material are satisfied, e.g. judging by measuring the initial peak and the integrated value by time of torque during rotation and an apparatus for judging quality provided with a mechanism 4 for detecting the initial peak of the torque and a mechanism 35 for measuring the integrated value by time when the joint made of the resin is rotated and an apparatus for preparing the jointed article of the resin pipe/ joint is provided.;COPYRIGHT: (C)2001,JPO
