This specification covers industry standards which have been determined by consensus to demonstrate compliance to the requirements (”the Rules”) for Level 1, 2, 3, 4 Normal Category Aeroplanes. It includes only standards that are considered mature enough for general application to certification projects and have been found acceptable by committee consensus to propose to the civil aviation authorities (CAAs) for acceptance as a Means of Compliance to their Rules. CAAs may accept a specific revision of this specification as an acceptable Means of Compliance (MoC) to their requirements. The applicant must seek individual guidance from their respective CAA concerning the use of this specification and any referenced Specifications, Practices, Test Methods, or Guides to show compliance to the CAA rules. Alternatively, an applicant may propose a MoC other than those included in this specification, but it is their responsibility to obtain acceptance of their proposed MoC from their CAA.This specification covers requirements for flight (e.g., weight/mass and center of gravity, stall speed, takeoff performance, landing); structures (structural design envelope, structural design loads, flight load conditions, aeroelasticity, special factors of safety, emergency conditions); design and construction (flight control systems, landing gear systems, buoyancy for seaplanes and amphibians, occupant physical environment, fire protection); powerplant (powerplant installation, powerplant installation hazard assessment, powerplant installation ice protection, powerplant installation fire protection); equipment (systems and equipment function and safety, external and cockpit lighting, flight in icing conditions); and flight crew interface and other information (flightcrew compartment interface, instrument markings, airplane flight manual, continued airworthiness).1.1 Applicability: 1.1.1 This specification identifies the industry standards that have been determined by consensus to demonstrate compliance to the requirements (“the Rules”) for Normal Category Aeroplanes.1.1.2 Only standards that are considered mature enough for general application to certification projects and have been found acceptable by committee consensus to propose to the CAAs for acceptance as a Means of Compliance to their Rules are included.1.1.3 In the event that a particular CAA’s requirements are not harmonized with the other CAA’s requirements, the standards will be written to include the non-harmonized requirements as well as the harmonized requirements with the applicability defined in the standard.1.1.4 In addition to identifying the standards that have been approved by the F44 Committee, the structure of this specification follows the structure of the existing performance/objective-based rules for Normal Category aeroplanes as closely as practical. However, due to differences employed by the authorities in structuring the rules, some sections of this specification may parallel the structure of a particular authority’s rules, but not all. The intent was to structure this specification in such a way that the users could identify what standards would be applicable to specific rules with the specifications at the highest level and practices and test methods being at the next level down. Guides that support a specification or practice will be at the next level down from what they support.1.2 Civil Aviation Authorities: 1.2.1 CAAs may accept a specific revision of this specification as an acceptable Means of Compliance (MoC) to their requirements. Acceptance and applicability as a MoC to the CAA’s airworthiness rules remains the decision of the respective CAAs. CAAs may accept this specification, with or without limitations as defined in their specification acceptance document. For information on which CAAs have accepted these standards (in whole or in part) as an acceptable MoC to their Rules, refer to the ASTM F44 webpage (www.astm.org/COMMITTEE/F44.htm) which includes CAA website links.1.3 Applicant Responsibility: 1.3.1 The applicant must seek individual guidance from their respective CAA concerning the use of this specification and any referenced Specifications, Practices, Test Methods, or Guides to show compliance to the CAA rules. Alternatively, an applicant may propose a MoC other than those included in this specification but it is their responsibility to obtain acceptance of their proposed MoC from their CAA.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.

1.1 This specification covers test methods and acceptance criteria for determining the acceptability of gear oils for applications that specify a lubricant meeting the performance requirements of API Category GL-5 service. Lubricants that meet these performance requirements are typically intended for use in automotive axles, particularly those containing hypoid gears, operating under various combinations of high-speed/shock-load and low-speed/high-torque conditions.1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.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.

This specification covers engine oils for light-duty and heavy-duty internal combustion engines used under a variety of operating conditions in automobiles, trucks, vans, buses, and off-highway farm, industrial, and construction equipment. Automotive engine oils are classified in three general arrangements: S, C, and Energy Conserving. These arrangements are further divided into categories with performance measured as follows: SH, SJ, SL, SM, CF-4, CF, CF-2, CG-4, CH-4, CI-4, CJ-4, Energy Conserving associated with SJ, and Energy Conserving associated with SL. Different bench and chemical tests shall be performed to help evaluate some aspects of engine oil performance.1.1 This specification covers engine oils for light-duty and heavy-duty internal combustion engines used under a variety of operating conditions in automobiles, trucks, vans, buses, and off-highway farm, industrial, and construction equipment.21.2 This specification is not intended to cover engine oil applications such as outboard motors, snowmobiles, lawn mowers, motorcycles, railroad locomotives, or oceangoing vessels.1.3 This specification is based on engine test results that generally have been correlated with results obtained on reference oils in actual service engines operating with gasoline or diesel fuel. As it pertains to the API SL engine oil category, it is based on engine test results that generally have been correlated with results obtained on reference oils run in gasoline engine Sequence Tests that defined engine oil categories prior to 2000. It should be recognized that not all aspects of engine oil performance are evaluated by the engine tests in this specification. In addition, when assessing oil performance, it is desirable that the oil be evaluated under actual operating conditions.1.4 This specification includes bench and chemical tests that help evaluate some aspects of engine oil performance not covered by the engine tests in this specification.1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.5.1 Exceptions: 1.5.1.1 The roller follower shaft wear in Test Method D5966 is in mils.1.5.1.2 The oil consumption in Test Method D6750 is in grams per kilowatthour.NOTE 1: The kWh unit is deprecated. The preferred SI unit is the joule (J); 1 kWh = 3.6 MJ.1.5.1.3 The bearing wear in Test Method D6709 is in grams and is described as weight loss, a non-SI term.1.5.1.4 Some of the appendixes are verbatim from other sources, and non-SI units are included.1.6 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.
