轨道交通市场起伏变化。主要原因在于机构改革及私有化、全球化、对于提高性能及使用周期的质量要求，以及技术和法律的兼容。

The railway vehicle markets are in a state of flux; privatization and restructuring at the operators, globalization, rising quality requirements with regard to reliability and life cycle, plus technical and legal harmonization are major factor creating movement in the transport markets.

整个铁路工业，包括其供应商，均深受影响。

The entire railway industry, including its suppliers, is affected by the consequences.

为了迎接这些挑战，国际“铁路专用标准”与UNION的融合之下以IRIS（国际铁路工业标准）的形式诞生了，旨在满足厂商对于车辆质量及性能的要求。

To meet these new challenges, an international ‘railway-specific standard’ for management systems has been created in the form of IRIS (International Railway Industry Standard) under the coordination of UNIFE (Union des Industries Ferroviaires Europeenes). The aim is to satisfy the operators’ requirements concerning the quality and reliability of rolling stock.

四大系统生厂商（庞巴迪、西门子、阿尔斯通、安萨尔多?布雷达）率先鼓励并支持这一标准。

The initiative was largely instigated and supported by the four largest system manufacturers (Bombardier, Siemens, Alstom and Ansaldo Breda).

因此轨道交通制造商和供应商将有机会，由独立的、经UNIFE授权的认证公司进行审核和认证。

Suppliers and railway vehicle manufacturers will thus have the chance in future to be audited and certified by independent, UNIFE-accredited certification companies.

TUV NORD集团是第一批获得UNIFE/IRIS集团授权可进行IRIS认证的公司。认证程序是建立在ISO 9001: 2000的基础之上。不同之处在于，根据审核评估程序来评估企业不同的管理制度，使企业可采取针对性的改进办法。

The TUV NORD Group is one of the first certification companies to have concluded an accreditation agreement with the UNIFE/IRIS group. The certification procedure is base on the procedure established in ISO 9001: 2000. The difference is that the audit assessment is based on a scoring procedure through which the companies receive a differentiated appraisal of their management system, enabling them to adopt targeted approaches towards potential improvements.

TUV NORD是国际公认的在管理体系认证领域具有多年经验的认证集团。我们将提供具有国际公信力的IRIS认证。并可与其它管理体系进行联合认证。所有公司的IRIS认证信息将存于IRIS数据库，并面向市场。我们的审核员均为经验丰富并具有IRIS专业资格的专家。

TUV NORD CERT is an internationally recognized certification company with many years of experience in the field of management system certification. We can offer you internationally recognized certification according to IRIS. If other management systems are certified at the same time this may give rise to synergies. All companies certified according to IRIS are published in the IRIS database, which is accessible to all those involved in the market. Our auditors are skilled specialists with an additional IRIS-specific qualification.
