Audit Requirement for Product Certification

Before a product can be awarded a Certificate, it has to be established that there exist a sound and stable Quality System implementation at the Applicant’s manufacturing facility. The Certification Audit aims to achieve this.

The Product Certification Scheme requires that the manufacturer exercise adequate control of quality in the key processes involved in the manufacturing of the product. The audit is based on elements of the ISO 9001: 2008 Quality Management System, with emphasis on the product design control, production control, raw materials/ components inspections, control of non-conformities, corrective actions and measurements.

The applicant shall be notifed of the audit and it shall be carried out by qualified TNB Quality Assurance Inspectors. If the auditors found any deficiencies in the Quality System implementation, Non Conformance Reports (NCR) shall be issued. All NCR shall be successfully closed before a product can be recommended for
award of the Certificate.

all products supplied to TNB is meeting the product technical specification requirement. TNB Research is given responsibility as a second party inspection body to manage and perform product inspection on behalf of TNB.
