5.1 This test method was developed to evaluate automotive engine oils for protection against oil thickening and piston deposits during moderately high-speed, hightemperature service.5.1.1 The increase in kinematic viscosity of the oil indicates the tendency of an oil to thicken because of oxidation. In automotive service, such thickening can cause oil pump starvation and resultant catastrophic engine failures.5.1.2 The deposit ratings for an oil indicate the tendency for the formation of deposits throughout the engine, including those that can cause sticking of the piston rings in their grooves. In automotive service, such ring sticking can cause a loss of compression pressures in the engine.5.2 The test method was developed to correlate with oils of known good and poor protection against oil thickening and piston deposits. Specially formulated oils that produce less than desirable results with unleaded fuels were also used during the development of this test.5.3 The Sequence IIIH engine oil test has been recommended as a replacement for the Sequence IIIG test and is expected to be used in specifications and classifications of engine lubricating oils, such as the following:5.3.1 Specification D4485.5.3.2 Military Specification MIL-PRF-2104.5.3.3 SAE Classification J183.1.1 This test method covers an engine test procedure for evaluating automotive engine oils for certain high-temperature performance characteristics, including oil thickening (as measured by kinematic viscosity increase), piston deposits, ring sticking, oil consumption, and phosphorus retention. Such oils include both single-viscosity and multiviscosity grade oils that are used in both spark-ignition, gasoline-fueled engines, as well as in diesel engines.1.1.1 Additionally, with nonmandatory supplemental requirements, a Sequence IIIHA Test (Mini Rotary Viscometer and Cold Cranking Simulator measurements), or a Sequence IIIHB Test (phosphorus retention measurement) can be conducted. These supplemental test procedures are contained in Appendix X1 and Appendix X2, respectively.NOTE 1: Companion test methods used to evaluate engine oil performance for specification requirements are discussed in SAE J304.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.2.1 Exceptions: 1.2.1.1 Where there is no direct SI equivalent such as screw threads, national pipe threads/diameters, tubing sizes, and valve sizes and springs.1.2.1.2 The ring end gaps in Table A8.7, the dimensions for the blowby ventilation support bracket in Fig. A3.2, and the torque wrenches in Table A8.1 are in inch-pound units.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. Specific warning statements are provided in 6.11.6, 7.1, 7.2.1, and 7.3.1.4 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 The determination of dimensional change of pile yarn floor covering is useful in quality and cost control during manufacture of pile yarn floor covering. The appearance and performance may be affected by the changes in the dimensions of pile yarn floor covering. This test method is considered satisfactory for acceptance testing of commercial shipment because current estimates of between laboratory precision are acceptable, and this method is commonly used in the trade for acceptance testing.5.2 If there are differences of practical significance between reported test results for two laboratories (or more), comparative tests should be performed to determine if there is a statistical bias between them using competent statistical assistance. As a minimum use the samples for such comparative tests that are as homogenous as possible, drawn from the same lot of material as the samples that resulted in disparate results during initial testing and randomly assigned in equal numbers to each laboratory. The test results from the laboratories involved should be compared using a statistical test for unpaired data, a probability level chosen prior to the testing series.

4.1 This guide covers animal implantation methods and analysis of the explanted DBM-containing material to determine whether a material or substance possesses osteoinductive potential, as defined by its ability to cause bone to form in vivo at a site that would otherwise not support bone formation, that is, heterotopically in a skeletal muscle implant site. For in vitro evaluation see Test Method F2131 for in vitro assessment of rhBMP 2.4.2 The test methods described here may be suitable for defining product specifications, cGMP lot release testing, research evaluation, regulatory submission, and so forth, but a positive outcome should not be presumed to indicate that the product will be osteoinductive in a human clinical application. At present, the only direct assays to assess new bone formation are in vivo, since the property of bone conduction or induction can only be assessed in a heterotopic or orthotopic site in a living animal. When these products are implanted in an orthotopic site, osteogenic factors already present at the implantation site may contribute to and enhance bone formation in conjunction with the osteoconductive nature of the product. Thus, orthotopic implantation of products may result in bone formation by acting on existing bone-forming cells and not by causing mesenchymal stem cells to become osteochondroprogenitor cells. In contrast, when these products are implanted in a heterotopic site, no native osteogenic factors are present to contribute to or enhance bone formation. Thus, heterotopic implantation of products will only result in new bone formation by causing mesenchymal stem cells to become osteochondroprogenitor cells. In vitro assays have been described and some believe they may correlate to the results obtained from in vivo assays. However such in vitro assays measure only some of the biochemical marker(s) associated with in vivo bone formation and are therefore only indirect assays for osteoinductive activity or the capacity to promote new bone formation. Many factors or combinations of factors contribute to osteoblast progenitor cells differentiating and/or proliferating into bone-forming cells in vitro that are both osteoinductive and osteoconductive when they are implanted in vivo. Thus, only an in vivo assay method currently directly considers the many potential factors involved in new bone formation induced by DBM-containing biomaterials. The qualification of a DBM or DBM-containing material should also encompass product characterization such as that described in Appendix X1.1.1 This guide covers general guidelines to evaluate the effectiveness of DBM-containing products intended to cause and/or promote bone formation when implanted or injected in vivo. This guide is applicable to products that may be composed of one or more of the following components: natural biomaterials (such as demineralized bone), and synthetic biomaterials (such as calcium sulfate, glycerol, and reverse phase polymeric compounds) that act as additives, fillers, and/or excipients (radioprotective agents, preservatives, and/or handling agents) to make the demineralized bone easier to manipulate. It should not be assumed that products evaluated favorably using this guidance will form bone when used in a clinical setting. The primary purpose of this guide is to facilitate the equitable comparison of unique bone-forming products in in vivo heterotopic models of osteoinductivity. The purpose of this guide is not to exclude other established methods.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with the use of DBM-containing bone-forming/promoting products. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices involved in the development of said products in accordance with applicable regulatory guidance documents and in implementing this guide to evaluate the bone-forming/promoting capabilities of the product.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.
