quality product dispute situation:
The demand side believes that the "mineral processing equipment" involved in the case provided by the supplier has a very poor appearance and tampering marks on the nameplate. All products do not have inspection certificates and do not meet the requirements of the parties and national and industry standards;
The supplier believes that the equipment involved has been produced and delivered in accordance with the procurement contract, and the demand side has started mineral processing on its own for several months.
In order to clarify whether the "mineral processing equipment" involved in the case has quality problems and whether it complies with the provisions of the procurement contract between the two parties, the purchaser proposed to conduct quality appraisal. However, the supplier believed that the “mineral processing equipment” involved in the case did not meet the objective conditions for quality appraisal.
quality analysis results: The
quality analysis expert group conducted on-site verification on the installation status, name, model, quantity, complete machine name brand and manufacturer of the "mineral processing equipment" involved in the case. At the same time, it conducted an on-site investigation of all the equipment involved in the case and made the following suggestions and conclusions:
1) Some of the equipment involved lacked necessary safety precautions. Full protection device, there are potential safety hazards;
2) The performance of some of the equipment involved does not comply with relevant industry standards or the agreement between the parties, affecting the long-term stable operation of the equipment;
3) Most equipment does not have nameplate identification, and all equipment does not have technical documents such as operating instructions;
4) Some manufacturer brands are inconsistent with the contractual agreements between the parties.
