The words you will meet on ISO courses and in audits, in plain English. These are our own explanations — the formal definitions are in each standard (and in ISO’s free Online Browsing Platform).
A

- Audit ISO 19011
A systematic, independent and documented process for obtaining evidence and evaluating it objectively to decide how far audit criteria are met.
- Audit conclusion ISO 19011
The overall outcome of an audit, reached by the audit team after considering the audit objectives and all the findings.

What you audit against: the requirements of the standard, the organisation’s policies and procedures, contracts or legal requirements.
- Audit evidence ISO 19011
Records, statements of fact or other information that is relevant to the audit criteria and can be verified.

An independent organisation that audits management systems and issues certificates when they conform to a standard. Also called a registrar in some countries.
- Compliance obligations ISO 14001

- Conformity Harmonized Structure terms
Fulfilment of a requirement.

- Corrective action Harmonized Structure
Action to eliminate the cause of a nonconformity and prevent it happening again, usually after a root cause analysis.

- Environmental aspect ISO 14001
An element of an organisation’s activities, products or services that interacts or can interact with the environment — for example emissions to air or use of water.
- Environmental impact ISO 14001
A change to the environment, harmful or beneficial, resulting from an environmental aspect.
