33、resenting the purchaser shall haveauthorized access to the carriers being loaded for shipment tothe purchaser. The purchaser shall be afforded all reasonableand available facilities at the point of shipment for samplingand inspection of the material, which shall be conducted so asnot to interfere wi
34、th the loading of the carriers unnecessarily.9.2 Third party certification, either continuous or at regularintervals, shall be recognized as an alternative to lot inspection.9.3 Failure to conform to any one of the requirements of thisspecification shall constitute grounds for nonacceptance.10. Prod
