NOTEThe edi
34、ting instructions contained in this corrigendum define how to merge the material contained therein into the existing base standard and its amendments to form the comprehensive standard. The editing instructions are shown in bold italic. Four editing instructions are used: change, delete, insert, and
35、 replace. Change is used to make corrections in existing text or tables. The editing instruction specifies the location of the change and describes what is being changed by using strikethrough (to remove old material) and underscore (to add new material). Delete removes existing material. Insert add
36、s new material without disturbing the existing material. Insertions may require renumbering. If so, renumbering instructions are given in the editing instruction. Replace is used to make changes in figures or equations by removing the existing figure or equation and replacing it with a new one. Edit
37、ing instructions, change markings, and this NOTE will not be carried over into future editions because the changes will be incorporated into the base standard.11Notes in text, tables, and figures of a standard are given for information only and do not contain requirements needed to implement this st

39、4.4 Test cycles Change the first paragraph as shown below: The test procedure shall consist of subjecting the test samples to repeated test cycles following an initial screening test (see Clause 4.3). Each test cycle shall consist of the following parts and shall be performed in the following order:
40、 4.5 Temperature aging Change the fourth paragraph of 4.5.1 as shown below: 4.5.1 Aging by circulating electric current The temperatures in all samples shall be monitored by one or more thermometers or thermocouples located on each sample. The relative position of the thermometers or thermocouples s
41、hall be the same for all samples, including the control sample. The monitored temperatures on individual test and control samples shall have a degree of uniformity of 2 C at temperatures under 300C and 3 C for temperatures over 300 C, for the same monitored locations. The monitored temperatures on individual test samples shall not be more than 2 C below the control sample at temperatures under 300 C and not more than 3 C below the control sample for temperatures equal to or above 300 C for the same corresponding monitored locations.
