22、technical specification. Any accessories which are not essential to the retention of the insert in the housing (shell) shall be removed. 3.2 Unless specified in the technical specification, the following details shall be stated: initial measurements; torsional load value; value for EN2591-312; value

23、 for measuring the displacement of the insert; 1) during the application of the load, 2) after removal of the load, final measurements and requirements. 4 Method 4.1 Initial measurements Measurement of the angular position of the insert in the housing. 4.2 Procedure The specimens shall be submitted

24、to a torsional load applied to their rear face. This load shall be increased at a nominal rate of approximately0,5Nm/s until the specified value is reached, and maintained for a minimum of1min. Repeat the procedure in the opposite rotational direction. 4.3 Final measurements and requirements (if app

25、licable) The angular displacement of the insert in housing shall be measured under load, it shall not be greater than the specified value. The specimens shall be subjected to the following test sequence: EN2591-101; EN2591-312. 1) Published as AECMA Prestandard at the date of publication of this sta
