1.1 This guide describes manual sampling procedures for coal contained in railroad cars. These procedures are used to provide samples for general analysis and for the determination of total moisture. The gross sample is to be crushed and further prepared for analysis in accordance with Method D 2013 and Test Methods D 2234. 1.2 This guide provides instructions for sampling only the top 18 to 24 in. of a railcar. The user is cautioned that samples so obtained do not represent material below the point of penetration. 1.3 The user is cautioned that, during the removal of increments, spillage of coal from the sampling device is to be avoided. Spillage can result in a size biasing of the various sizes in the coal. 1.4 The samples obtained by this guide under Condition D (from stationary sources, see Test Methods D 2234), shall be considered less representative than samples taken from the same lot under Conditions A, B, or C (Test Methods D 2234). 1.5 The quantities stated in either acceptable SI units or in inch-pound units shall be regarded separately as standard. The quantities stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining quantities in any way. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

5.1 Test Method—The data obtained from the use of this test method provide a comparative index of the fuel-saving capabilities of automotive engine oils under repeatable laboratory conditions. A baseline calibration oil (hereafter referred to as BC oil) has been established for this test to provide a standard against which all other oils can be compared. The BC oil is an SAE 5W-30 grade fully formulated lubricant. There is a direct correlation of Test Method D6837 (Sequence VIB) Fuel Economy Improvement (FEI) by percent with the fuel economy results obtained from vehicles representative of current production running under the current EPA testing cycles. The test procedure was not designed to give a precise estimate of the difference between two test oils without adequate replication. Rather, it was developed to compare a test oil to BC oil. Companion test methods used to evaluate engine oil performance for specification requirements are discussed in the latest revision of Specification D4485.5.2 Use—The Sequence VIB test method is useful for engine oil fuel economy specification acceptance. It is used in specifications and classifications of engine lubricating oils, such as the following:5.2.1 Specification D4485.5.2.2 API Publication 1509.5.2.3 SAE Classification J304.5.2.4 SAE Classification J1423.1.1 This test method covers an engine test procedure for the measurement of the effects of automotive engine oils on the fuel economy of passenger cars and light-duty trucks with gross vehicle weight of 3856 kg or less. The tests are conducted on a dynamometer test stand using a specified spark-ignition engine with a displacement of 4.6-L. It applies to multiviscosity grade oils used in these applications.1.2 This test method also provides for the running of an abbreviated length test that is referred to as the VIBSJ. The procedure for VIBSJ is identical to the Sequence VIB with the exception of the items specifically listed in Annex A13. The procedure modifications listed in Annex A13 refer to the corresponding section of the Sequence VIB test method.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3.1 Exceptions—Where there is no direct SI equivalent such as screw threads, National Pipe Threads/diameters, tubing size, or single source supply equipment specifications. Brake Specific Fuel Consumption is measured in kilograms per kilowatthour. In Figs. A2.4, A2.5, and A2.8, inch-pound units are to be regarded as standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.1.5 This test method

4.1 Static measurements of tires are important to tire manufacturers, processing engineers, and vehicle design engineers for purposes of commerce (in consumer/vendor agreements) and in tire research and development.4.2 The procedures are sufficiently detailed to achieve commercially acceptable reproducibility among laboratories and may therefore be used for specification, compliance, or reference purposes.4.3 Changes attributable to growth after inflation may be obtained by comparing measurements made immediately after inflation with those made 18 to 24 h later.1.1 This test method covers methods for performing certain mechanical static measurements on tires. The term “static” implies that the tire is not rotating while measurements are being made.1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 These guidelines provide procedures for manually collecting gross samples from beneath the exposed surface of coal in railroad cars, barges, trucks, or stockpiles taking into account the wide variety of conditions that may be encountered. The samples are further processed for the laboratory to provide estimations of the coal quality. The use of this practice is conditional upon agreement among all interested parties concerning all relevant details of sample collection before sampling begins. These include, but are not limited to: lot size; number and mass of increments; the size, shape, and manipulation of the increment collection devices; location of increment collection site or sites; circumstances under which increments are not to be collected or suspended; and safety precautions. It is preferable that such agreements be in writing. The user is cautioned that samples so obtained do not represent material below the point of penetration.1.1 This practice covers procedures for obtaining a manual gross sample from beneath the surface of coal in railroad cars, barges, trucks, or stockpiles. These procedures are to be used to provide gross samples for estimating the quality of the coal. The gross samples are to be crushed, divided, and further prepared for analysis in accordance with Practice D2013.1.2 This practice provides instruction for sampling beneath the exposed surface coal to a depth of approximately 61 cm (24 in.). Collect samples at this depth to get below the surface of the material, since drying and oxidation may have occurred at, or near the surface. Changes in moisture, in particle size, and in other properties continue to occur deeper in the coal and, although not as drastic as near the surface, will cause the method to be biased. The user should review the conditions of the coal (weather conditions, prior transport, settling time, and so forth, see 8.1) so that the interested parties can agree that potential biases are not overly great or that some adjustment in specifications is warranted. Sample increments collected from the surface layer(s) of coal in railroad cars, barges, or stockpiles are classified condition “D” (see Practice D2234/D2234M, Increment Collection Classification). It is a good practice to require that “details of sampling procedure shall be agreed upon in advance by all parties concerned” whenever collection of sample increments falls under condition “D.” This practice offers a sampling procedure that parties may use to meet requirements of Practice D2234/D2234M for condition “D.” The practice does not produce samples that satisfy precision requirements of Practice D2234/D2234M general-purpose sampling, or Practice D2234/D2234M special-purpose sampling.1.3 The user is cautioned that samples of this type do not satisfy the minimum requirements for probability sampling and as such cannot be used to draw statistical inferences such as precision, standard error, or bias.1.4 This sampling method is intended for use only when sampling by more reliable methods that provide a probability sample is not possible.1.5 The quantities stated in either acceptable SI units or in inch-pound units are regarded separately as standard. The quantities stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining quantities in any way.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

1.1 This test method covers an engine test procedure for the measurement of the effects of automotive engine oils on the fuel economy of passenger cars and light-duty 3856 kg (8500 lb), or less, gross vehicle weight trucks. The tests are conducted using a specified 4.6-L spark-ignition engine on a dynamometer test stand. It applies to multiviscosity grade oils used in these applications. Companion test methods used to evaluate engine oil performance for specification requirements are discussed in the latest revision of Specification D4485.1.2 The values stated in either SI units or other units shall be regarded separately as the standard. Within the text, the SI units are stated first with the other units shown in parentheses. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other, without combining values in any way.1.3This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.1.4 This test method is arranged as follows:Subject SectionIntroduction 1Referenced Documents 2Terminology 3Summary of Test Method 4Significance and Use 5Apparatus 6General 6.1Test Engine Configuration 6.2Laboratory Ambient Conditions 6.3Engine Speed and Load Control 6.4Engine Cooling System 6.5External Oil System 6.6Fuel System 6.7Engine Intake Air Supply 6.8Temperature Measurement 6.9AFR Determination 6.10Exhaust and Exhaust Back Pressure Systems 6.11Pressure Measurement and Pressure Sensor Locations 6.12Engine Hardware and Related Apparatus 6.13Miscellaneous Apparatus Related to Engine Operation 6.14Reagents and Materials 7Engine Oil 7.1Test Fuel 7.2Engine Coolant 7.3Cleaning Materials 7.4Sealing Compounds 7.5Preparation of Apparatus 8Test Stand Preparation 8.2Engine Preparation 9Cleaning of Engine Parts 9.2Engine Assembly Procedure 9.3General Assembly Instructions 9.3.1Bolt Torque Specifications 9.3.2Sealing Compounds 9.3.3New Parts Required for Each New Engine 9.3.4Harmonic Balancer 9.3.5Oil Pan 9.3.6Intake Manifold 9.3.7Camshaft Covers 9.3.8Thermostat 9.3.9Thermostat Housing 9.3.10Coolant Inlet 9.3.11Oil Filter Adapter 9.3.12Dipstick Tube 9.3.13Water Pump 9.3.14Sensors, Switches, Valves, and Positioners 9.3.15Ignition System 9.3.16Fuel Injection System 9.3.17Intake Air System 9.3.18Engine Management System (Spark and Fuel Control) 9.3.19Accessory Drive Units 9.3.20Exhaust Manifolds 9.3.21Engine Flywheel and Guards 9.3.22Lifting of Assembled Engines 9.3.23Engine Mounts 9.3.24Calibration 10BC Pre-Test Verification 10.1Engine/Test Stand Calibration 10.2Procedure 10.2.1Reporting of Reference Results 10.2.2Analysis of Reference Oils 10.2.3Flush Effectiveness Demonstration 10.2.4Instrument Calibration 10.3Engine Load Measurement System 10.3.1Fuel Flow Measurement System 10.3.2Coolant Flow Measurement System 10.3.3Thermocouple and Temperature Measurement System 10.3.4Humidity Measurement System 10.3.5Other Instrumentation 10.3.6Test Procedure 11Preparation for Initial Start-Up of New Engine 11.1Initial Engine Start-Up 11.2Coolant Flush 11.3New Engine Break-In 11.4Routine Test Operation 11.5Start-Up and Shutdown Procedures 11.5.8Flying Flush Oil Exchange Procedures 11.5.9Test Operating Stages 11.5.10Stabilization to Stage Conditions 11.5.11Stabilized BSFC Measurement Cycle 11.5.12Data Logging 11.5.13BC Oil Flush Procedure for BC Oil Before Test Oil 11.5.14BSFC Measurement of BC Oil Before Test Oil 11.5.15Test Oil Flush Procedure 11.5.16Test Oil Aging 11.5.17BSFC Measurement of Aged Test Oil 11.5.18BC Oil Flush Procedure for BC Oil After Test Oil 11.5.19BSFC Measurement for BC Oil After Test Oil 11.5.20General Test Data Logging Forms 11.5.21Diagnostic Review Procedures 11.5.22Determination of Test Results 12Final Test Report 13Validity Statement 13.1Report Format 13.2Precision, Validity, and Bias 14Precision 14.1Validity 14.2Test Stand Calibration Status 14.2.1Validity Interpretation of Deviant Operational Conditions 14.2.2Keywords 15ANNEXESRole of ASTM Test Monitoring Center Annex A1Detailed Specifications and Drawings of Apparatus Annex A2Oil Heater Cerrobase Refill Procedure Annex A3Engine Part Number Listing Annex A4Flying Flush Checklists Annex A5Safety Precautions Annex A6Report Format Annex A7Control Chart Technique for Stand/Engine Severity Adjustment (SA) Annex A8Statistical Equations for Mean and Standard Deviation Annex A9Fuel Injector Evaluation Annex A10Pre-test Maintenance Checklist Annex A11APPENDIXESProcurement of Test Materials Appendix X1Data Dictionary Appendix X2
