The testing results suggests that the increase of H2S concentration will raise the brittleness coefficient, leading to the decrease of corrosion resistance for either X70 base metals or welding joints. Meanwhile, the results reveals that effect of H2S concentration on X70 base metals and welding joints is different: the influence of H2S concentration on welding joints'SSCC is bigger than on base metals'SSCC.

揭示了随着硫化氢浓度的增加，国产X70管线钢及其焊接接头的脆性系数增加，抗腐蚀能力减弱；硫化氢浓度对国产X70管线钢母材和焊缝的SSCC性能有着不同程度的影响：在相同的试验条件下，焊缝的脆性系数显著大于母材的脆性系数，即焊缝较母材的SSCC敏感性大。

At this time, we have sent personnel to attend international IEC/TC111 activities. Under coordination by the Standard Administration of China, a technical committee is formed in corresponding to the TC111 WG3 (China WG3 working group). The task of forming a working group for test procedures of national standards for the density of toxic substances of electronic and electrical products is completed. The formation of a working group for industry standards for the prevention of pollution caused by electronic information products had been completed in October, 2004. This working group starts on the formation of standards for limits, test standards, leadless soldering standards, and certification and labeling standards.

目前，我们已经派员积极参与了国际 IEC/TC111的活动，在国标委的统一协调下，牵头组织了中国对应 TC111的 WG3的一个技术委员会（目前暂称为中国 WG3工作组）；组建电子电气产品有害物质浓度检测程序国家标准工作组的工作已经完毕；电子信息产品污染控制行业标准工作组已经在2004年10月组建完成，已经开始了制定电子信息产品有毒有害物质的限量标准、检测标准、无铅焊接标准、认证与标识标准的工作
