Consultancy in:

  • quality requirements regarding tested samples,
  • quality of the customer’s product: at the stage of delivery, handling, in production and at the release of the end product,
  • assistance in composing mixes of liquefied petroleum gases (LPG) meeting quality standards and legal regulations,
  • requirements regarding commercial documentation confirming product quality.

Training in:

  1. Sampling of liquefied petroleum gases (LPG, propane, butane, propane-butane) as per the currently binding standard PN-EN ISO 4257 and ZN/MG/CN-18:2007 (at the Terminal in Brzeźno).
  2. Performing tests using methods binding at the Laboratory
  3. Operating testing apparatus and supervising the equipment
  4. Implementing the management system at the Laboratory in line with PN-EN ISO/IEC 17025.

Additional services:

  • Performing internal audits at testing laboratories.
  • Issuing opinions and interpretations regarding tested samples.
