Total questions:255，including 12 K.O.questions。
   总共255个问题，其中包括12个K.O.问题
   1. Knock-out（K.O.）questions 关键性问题
   2. Open questions which are assessed through a four level approach for assessing the level of maturity of processes and the grade/extension of implementation（Optimized，Qualified，Defined，Poor）开放式问题：通过在审核时评分过程的成熟程度和实施的程度，设定了四种不同级别（优秀，合格。可以。差）。
   3. Closed questions（Yes/No）without progressive maturity levels封闭式问题：只有满足/不满足，没有递进的成熟度级别。
  Note：Questions indicated as ‘Non applicable’（'NA'）are not assessed and relevant justification shall be documented。注：如果问题被指明为“不适用”（即NA），这些问题将不会被审核，但要说明“不适用”的原因，并被形成文件。
  knock out questions（K.O.）关键性问题（K.O.问题）：
   A detailed pre assessment of the Knock Out（K.O.）questions shall be carried out to ascertain the readiness to undertake the audit。
   对K.O.问题应逐条进行预审核，以确定能否开始正式的审核。
   Fulfilment is considered as a prerequisite for IRIS certification。
   满足K.O.问题的要求是开始IRIS认证的前提条件。
   K.O. questions are not scored。   K.O.问题不打分。
   When a K.O.requirement is not met，the whole audit fails。The Certification process has to start with a new request（covering the full audit process again）。
   一旦K.O.问题没有满足，将不能通过审核。组织需要重新递交认证申请（审核过程将重新覆盖所有要素）。
   K.O.问题一共12个，其中2个只适用于信号系统的公司。
