reduced to a minimum.The force shall be applied to the test piece without shock.NOTEIt is recommended that the machine be isolated from external vibration and shock.The testing machine shall be verified and shall meet the requirements of at least class 1 in accordance with ENISO 7500-1:1999.The type of machine (e.g. servo-controlled electro-mechanic, servo-controlled hydraulic or sliding weight machine)shall be indicated in the test report.6.2 Extension measuring deviceThe extension shall be measured using an extensometer which meets the bias requirements of at least class 1 inaccordance with EN 10002-4:1994 and a resolution lower than or equal to one tenth of this bias value.The extensometer shall be calibrated at intervals not exceeding 3 years. If the predicted test time exceeds the dateof the expiry of the calibration certificate, the extensometer shall be calibrated prior to commencement of therelaxation test.The extensometer gauge length depends upon the performance characteristics of the extensometry used tomeasure the strain. A minimum gauge length of 100 mm is recommended. If insufficient material is available,shorter gauge lengths may be used provided that the extensometry used has a sufficient resolution. The use ofshorter gauge lengths shall be recorded in the test report. The extensometer should be able to measure theextension on two opposite sides of the test piece. Side contact extensometry is permitted; where used this shall bereported in the test report.NOTEWhen measured on the opposite sides, the average extension should be reported.6.3 Heating device6.3.1 Permissible temperature deviationsThe heating device shall heat the test piece to the specified temperature (T).The permitted deviations betw
