ISO/TS 11774:2011提供了无损检测（NDT）人员、程序和设备的资格鉴定方法，用于根据基于性能的资格鉴定计划中建立的文件化程序进行特定无损检测。 ISO/TS 11774:2011的实施需要相关行业委员会（ISC）和资格认证机构之间的合作，以确保满足具体的绩效预期。 ISO/TS 11774:2011中描述的鉴定方法基于候选人证明其在检测和确定关键不连续性方面的能力，与ISC制定的基于性能的鉴定计划中要检测和确定的不连续性相当。 第二方（雇主）可能- 基于）资格认证和批准（例如，根据ANSI/ASNT CP-189）或资格认证和第三方认证（例如，根据ISO 9712或EN 473），随后的在职培训不能提供安全关键检查所需的置信度，ISO/TS 11774:2011提供了帮助个人准备基于绩效的资格考试的标准。 ISO/TS 11774:2011的认证仅限于特定应用，使用基于性能的认证计划中的特定文件化程序。

ISO/TS 11774:2011 provides a method for qualification of non-destructive testing (NDT) personnel, procedures, and equipment for specific non-destructive tests conducted in accordance with documented procedures established within a performance-based qualification programme. Implementation of ISO/TS 11774:2011 requires cooperation between applicable industry sector committees (ISCs) and qualification bodies to ensure that specific performance expectations are addressed. The qualification methodology described in ISO/TS 11774:2011 is based upon the ability of a candidate to demonstrate capability in detecting and sizing critical discontinuities equivalent to those to be detected and sized in the performance-based qualification programme as established by the ISC. It is possible that second party (employer-based) qualification and approval (e.g. in accordance with ANSI/ASNT CP-189) or qualification and third party certification (e.g. in accordance with ISO 9712 or EN 473), followed by on-the-job training does not provide the required degree of confidence for safety critical inspections, and ISO/TS 11774:2011 provides criteria to assist in preparing an individual for performance-based qualification examinations. Qualification to ISO/TS 11774:2011 is limited to the specific applications, using the specific documented procedure in the performance-based qualification programme.
