As part of the audit, initially the HERING platform roof of the Bodenheim light type in Moers was thoroughly examined. The audit leaders, who were commissioned by GüteZert® GmbH, established whether the trade and the company's own internal HERING quality management system meet the requirements of DIN EN ISO 9001:2008. Following the review conducted in Moers on 17 and 18 March, the audit was continued in Holzhausen on 19 March.
The recertification had a successful outcome, with all areas of the Holzhausen site successfully passing the audit! This means that the company may use the Monitoring ÜGG-Symbol.
