Significance and Use4.1 This specification specifies the properties and limits fortriglyceride burner
33、 fuels to provide acceptable performance inliquid fuel burning equipment. It is for use in contracts for thepurchase of triglyceride burner fuels and for the guidance ofconsumers of such fuels. It may also be used by third-partytesting agencies in evaluating burner equipment for the pur-poses of ver
34、ifying performance and safety of the oil-burningappliances and by regulators of such fuel and equipment use.5. Requirements5.1 The triglyceride burner fuels shall be homogeneous,consisting primarily of triglycerides and naturally occurringconstituents of triglycerides and shall conform to the limiti
35、ngrequirements in Table 1.5.2 Buyer and seller may agree to modifications of limitingrequirements to meet special operating conditions provided themodifications fall within the limits specified in Table 1 for eachgrade.NOTE 2The grades specified may or may not correlate directly withsimilar grades i
36、n other ASTM standards. The usage descriptions of eachgrade may not describe all the uses but are included as general informa-tion.5.3 The triglyceride burner fuel grades are described asfollows:5.3.1 Grade TBF5Aburner fuel comprised of commercialrecycled and unused cooking oils, greases and rendere
37、d animalfats having a pour point below 21C in accordance with TestMethod D97. The requirements for this type of triglycerideburner fuel are presented in Table 1. This grade is intended foruse in industrial burners and commercial boilers equipped withdevices that use steam or compressed air to atomiz
38、e fuel oil ofhigher viscosity. Preheating may be necessary in some types ofequipment for burning this fuel and in colder climates for easeof handling.5.3.2 Grade TBF6Aburner fuel comprised of commercialrecycled and unused cooking oils, greases and rendered animalfats having a pour point equal to, or
39、 higher than, 21C inaccordance with Test Method D97. The requirements for thistype of triglyceride burner fuel are presented in Table 1. Thisgrade is intended for use in industrial burners and commercialboilers equipped with devices that use steam or compressed airto atomize fuel oil of higher visco
40、sity. The use of this grademay require preheating in the storage tank to permit pumping.Additional preheating at the burner may be necessary to permitsatisfactory atomization. The extra equipment and maintenancerequired to handle this fuel grade may preclude its use in smallor unattended installatio
41、ns, or both.5.4 Triglyceride burner fuels shall remain homogeneous anduniform in storage and shall not separate by gravity or aginginto layers under normal operating conditions.NOTE 3Prolonged storage or equipment downtime may necessitatecirculation of the fuel oil in tank to prevent such separation
42、.5.5 The triglyceride burner fuel shall be free of solid orfibrous matter that could cause system handling or maintenanceproblems.6. Sample Collection and Handling6.1 Inspection of the material shall be agreed upon betweenthe purchaser and the supplier as part of the purchase order orcontract.6.2 Un
43、less otherwise specified, take a representative samplein accordance with Practice D4057, D4177 or other compa-rable sampling practices using a clean and appropriate samplecontainer. Containers previously holding a sample or any othertype of fluid are not considered appropriate containers.NOTE 4In ca
44、se of dispute, Practice D4057 is recommended as thereferee method.6.3 Aminimum sample size of 1 L is recommended for eachsample taken before compositing.6.4 Sample handling and mixing shall comply with PracticeD5854.7.
