3 Terms and definitions
Definitions for general terms can be found in EN ISO 9000 and the IAQG International Dictionary (located on the IAQG website).
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
ISO Online browsing platform: available at http://www.iso.org/obp
IEC Electropedia: available at http://www.electropedia.org/
3.1
customer
recipient of a product provided byan internal/external supplier or sub-tier supplier
3.2
mandatory data
common and translerable data systematically filled in and provided; if printed, this field shall be included on the printed form
3.3
optional data
all data fields that are not defined as mandatory by this standard; these fields may be requested by a customer or needed by the originator for their own purposes
4.6 When required, continuation/additional sheets and attachments shall include the same reference number as the original document.
NOTE Reference Annex A, the data fields Nonconformity Description’ (see No. 19) and ‘Disposition’
(see No. 25) may be presented either as a summary or in a clearly defined sub-structure (see No. 19 a-i and
No. 25 a-e).
4.7 The forms may be pre-printed, computer generated, or accessed via a net-based system (intranet/internet), but in all cases, the printing of lines and characters shall be clear and legible. The details entered on the forms shall preferably be machine/computer printed, but may be handwritten as long as upper case letters are used and the document remains legible.
NOTE The use of abbreviations should be kept at a minimum.
4.8 The information shall be in English, but other languages may be acceptable (e.g., bilingual: English and native) when specified in the contract.
NOTE The use of abbreviations should be kept to a minimum.
5 Code catalog
The following codes are recommended for codifying affected processes, causes of process deviations, and corrections made to remedy the nonconformity. If codes are defined by a contract and/or the originators already have codes defined that satisfy their needs, these codes shall take precedence over those proposed in the following sections.
NOTE The following codes represent a minimum selection of possible variances. In case of needing additional code definitions (e.g., software, electronic, composites, structures), the tables can be enhanced by using the existing structure.
5.1 Nonconformity process codes
A product nonconformity is typically associated with a process deviation. See Table 1 for a list of codes.
5.2 Nonconformity cause codes
The causes of process deviations are defined in Table 2. The categorization of the list is set up to facilitate the use of process improvement tools (e.g., cause and effect diagram). The ‘Main Term’ code can be used as the cause code, if appropriate, or further definition may be provided.
NOTE 1 One or more cause codes may be used to define the cause(s) for a product nonconformity.
NOTE 2 The allocation of a cause code could be either apparent (preliminary/Initial) or final, depending on the status of root cause analysis. For further support, see EN 9136 and the SCMH (“Root Cause Analysis and Problem Solving” chapter).
5.3 Nonconformity Corrective Action Codes
Common corrective action codes are defined in Table 3; intended to correspond directly to the cause codes identified in Table 2, as appropriate.
NOTE One or more corrective action codes may be used to define the corrective action(s) taken for a product nonconformity/cause code.
