It is the manufacturer’s responsibility to choose the appropriate route and to ensure that the recognition and acceptance of approval documentation is appropriate to their requirements. Whilst TWI Certification Ltd makes every effort to ensure that its approval documentation carries appropriate accreditation, and that evaluation and certification activities are carried out in accordance with best practice, it cannot guarantee acceptance by any particular customer or client.
