The Environmental Management System 2nd party pre-certification audit is a useful tool in evaluating if a facility is prepared for ISO 14000 Certification or if further corrective actions are required. The two types of pre-certification audits that can be conducted are desktop audits and site audits. A desktop audit focuses primarily on the implementation of the ISO 14000 standard with limited access to records. The site audit is an abbreviated version of the ISO 14000 Certification Audit. Employees are interviewed and evidence is gathered to identify any potential non-conformances. This audit is more in depth but will reflect what you will encounter during the actual Certification Audit.
