Comparator task definition
Prepare instrument list for the comparator task definition review. List the equipment references and identify the particular instrument or assembly concerned. Attach the available nameplate photographs or specification documents, and ask the supplier to address those references explicitly when identifying the proposed item and its corresponding technical documents. Ask which instruments should define the comparator pump request?
Request or submit intended comparison requirements, according to the proposed purchase scope. Name the requirement that needs a written answer and identify the proposed item concerned. Request clarification against the buyer document rather than a general category description, and compare the response with the same requirement when considering an alternative equipment configuration.
Comparator medium questions
Prepare medium description for the comparator medium questions review. Identify the substance, the circuit or component it concerns, and the relevant operating case. Include the composition or treatment information held by the project team, and ask the supplier which further fluid details are needed for the proposed item review. Ask which medium requirements should be submitted for supplier review?
Request or submit pump specification request, according to the proposed purchase scope. Identify the exact item or version about which information is requested. Ask for the specification associated with the proposed configuration, and compare its identification with the quotation and other requested documents before referring any inconsistency to the supplier for written clarification.
Comparator connection record
Prepare reference instrument interface for the comparator connection record review. Identify each interface and the item connected to it in the buyer drawing. Request the corresponding interface information for the proposed equipment, and ask for any separately required component to be identified before comparing the proposed configuration with the existing installation. Ask which connections should be confirmed for the proposed arrangement?
Request or submit test item drawing, according to the proposed purchase scope. Describe the information being requested and identify the equipment concerned. Request the corresponding technical document for the proposed item, and ask which specific parts of the buyer requirement are addressed so the response can be compared with the intended purchase scope.
Comparator scope comparison
Prepare pump description for the comparator scope comparison review. Identify the exact item or version about which information is requested. Ask for the specification associated with the proposed configuration, and compare its identification with the quotation and other requested documents before referring any inconsistency to the supplier for written clarification. Ask which included items should be clarified before ordering?
Request or submit accessory item list, according to the proposed purchase scope. Describe the access restrictions and the intended inspection or maintenance task. Attach available layout photographs or drawings, and ask the supplier what information is needed to review the proposed equipment against the buyer access requirement before the work scope is discussed.
