Requirements

 

The ENplus-Briquettes certification places the certified company under the obligation to follow several requirements on the internal quality management:

  • Monitoring of raw materials concerning quality and adequate storage; the raw materials must conform to the allowed raw materials for the quality class (see the table below)
  • Adequate technical equipment
  • Implementation of a quality management system (including complaint management and designation of a quality manager)
  • It must be ensured that non-conforming briquettes are not sold as certified products.
  • Moisture and raw density of the briquettes as well as the mass of the small casks must be inspected and documented on a daily basis during production.
  • The requirements for the product declaration on the imprint must be followed. Small casks must have a product declaration inlet or imprint.
  • Briquettes must be kept dry (including protection against moisture by condensation).
  • Certified briquettes shall only be transported by palettes of sufficient size, and these must be fixated by tension belts.
