You should check all the Contract requirements that you specified to the manufacturer in your purchase order during the Vendor document review. If the product doesn't meet the specifications, reject it.
"The VLR or VDR is the quantity received or discharged as measured on the vessel (TCV – ROB or OBQ) divided by the Bill of Lading (shore delivered at loading) or Outturn Quantity (shore received at discharge) respectively. The mean of the qualifying VLRs or the VDRs over several voyages is called the VEF (VEFL and VEFD for load and discharge respectively.)"
In mixed company I try to define any acronyms at the beginning of the discussion.
In my 2004 copy of API Standard 610 Centrifugal Pumps for Petroleum, Petrochemical and Natural Gas Industries, the only mention of rejection is in 8.2.7.3 and relative to vibration measurements during acceptance testing.
6 of the first 10 pages are "terms and definitions." The terms are written out as full words, and any acronyms appear immediately below the written term.
