API RP 1543-2009 pdf download.Documentation, Monitoring and Laboratory Testing of Aviation Fuel During Shipment from Refinery to Airport.
3 Definitions For the purposes of this document, the following definitions apply. 3.1 batch A distinct quantity of fuel that can be characterized by one set of test results including the type and amount of additives present. 3.2 batch makeup and clearance record A document used to establish new batches and record the individual batch information that defines a newly formed batch. This document provides the history on how incoming receipts were managed to assure product quality and traceability (see Annex F). 3.3 batch number A unique traceable batch reference number. 3.4 control check This is a visual check (for color, clear and bright, solid material, and undissolved water) plus fuel API Gravity (or density) determination. This check is frequently made to confirm the correct grade and unchanged quality of fuel stocks by comparison of the API Gravity result (or density) with the relevant batch API Gravity (or density). Should the (temperature corrected) gravities (densities) differ by more than 0.7 API [3 kg/m 3 (±0.003 kg/l)] a possibility of contamination exists and the matter shall be investigated further before the product is accepted for aviation use. It may be necessary to carry out further testing before such acceptance can be given. 3.5 dedicated Tankage, piping, valves, filters, etc. that are used to handle one grade of aviation product and no other products. 3.6 grade dedicated road transports Road transports that are used to handle one grade of aviation product and no other products. Before becoming grade dedicated, road transports are required to go through a grade change process before being used in aviation fuels (see API 1595). 3.7 line sample A sample obtained from a line sampling point, drawn while the product is flowing.
3.11 quality certification statement A certification statement shall appear on all quality certificates confirming that the product meets the requirements of the relevant specification. An example of a suitable statement is as follows: “Certified that this sample meets the relevant specification with respect to the above tests and complies with ASTM DXXXX, Latest Revision.” 3.12 retention sample A sample taken and stored in a retention sample container for the purpose of laboratory analysis at a later date in the event that the quality of the original product needs to be verified. 3.13 segregated (isolated tanks and pipelines) To achieve positive segregation for product quality control, the inlet and outlet pipelines on each tank, as well as any piping connections to other grades of products shall be fitted with either: a) a double block and bleed (DBB) valve arrangement (either using a single DBB valve, or using two valves with a drain arrangement in a pipe spool between them); b) a removable distance piece; or c) a spectacle blind. 3.14 single-tank composite sample Sample obtained by blending upper, middle and lower samples. For a vertical tank of uniform cross-section, the blend consists of equal parts of the three samples. 3.15 test certificates The purposes of a properly documented series of test certificates outlining the properties of the aviation fuel is listed below. a) Provide assurance that the product has been tested and meets the relevant specification. b) All records shall be dated and signed by the person responsible. For computer-generated records, a password- protected access system, traceable to the individual person, is acceptable as an alternative to a signature. c) Support the release of products for delivery to customers. Facility management is responsible for ensuring that the appropriate certificates cover aviation products in their care. The key documents include the RQC, COA, RTC, RC, and DD. The key documents are listed below.
3.15.2 delivery document DD This document supports any delivery of product. It is used to document the volume of product moved, pricing and other information required such as product hazard classification and other regulatory requirements. The most common DD is the bill of lading (BOL) document used in road or rail transport deliveries. 3.15.3 recertification test certificate RTC Where aviation product is transferred to an installation under circumstances which could in any way allow the possibility of contamination, then before further use or transfer, recertification is necessary. Recertification testing is carried out to verify that the quality of the aviation fuel concerned has not changed and remains within the specification limits, for example, after transportation in ocean tankers or multiproduct pipelines, etc. The RTC (see Annex A and Annex B for minimum requirements) shall be dated and signed by an authorized representative of the laboratory carrying out the testing. The results of all recertification tests shall be checked to confirm that: — the specification limits are met, and — no significant changes have occurred in any of the properties. The results of such tests shall be compared to the expected calculated results from a weighted average of the previous tank recertification and the receiving batches RQC or COA as well as reviewed for compliance with the specification limits. If any test results indicate that the sample does not comply with applicable specifications or is outside the allowable variance, the product shall be immediately quarantined and remain under quarantine until further testing has established that the quality is acceptable for aviation use. If more than three new batches are received into a tank, the comparison becomes difficult and possibly meaningless, and therefore the contents of the tank shall be tested against all the requirements of the specification.
