If it is verified that the cracks are not EC, then the test specimen passes the test.If SSC test representing a heat fails to conform to the specified requirements, the manufacturer may elect to make re-tests on two additional test specimens from the same pipe.If all of the re-tests conform

24、 to the requirements, the heat shall be accepted.If one or more of the re-tests specimens fails to conform to the specified requirements, the heat shall be rejected.在下列情况中的任何一种试验失效为：a）试样完全断开。b）经过720小时的试验时间后，采用10倍的放大镜目测试样的受检部位的裂纹，使用金相显微镜、扫描显微镜、或机械试验检查技术来确定受检部位的裂纹是否属于EC所造成的。（EC的含义是环镜开裂，仅包括硫化物应力开裂、应力腐蚀

25、开裂、氢致开裂。）如果裂纹经确认不是环境开裂，则该试样通过试验。若代表一炉产品的抗硫化物应力开裂试验不符合规定要求，则制造厂可以从同一支管子上另外再取2个样进行复验。若所有试样复验均符合要求，则该炉管子合格。若复验用一个或多个试样不符合规定要求，则该炉管子应判废。3.11.
