Mobile Air Conditioning System Refrigerant Emission Charts for R-134a and R-1234yf

2019-11-14
WIP
J2727
The “System Emissions Chart” contained herein is intended to serve as a means of estimating the annual refrigerant emission rate (grams per year) from new production A/C systems equipped with specified component technologies. It provides emission values for various component technologies that are currently available, and can be expanded as new technologies are commercialized. This document provides the information to develop an Excel file template “System Emissions Chart” for system emission analysis. The chart includes automotive compressor technologies for conventional mobile air conditioning systems as well as those using semi-hermetic compressors. This standard can be considered a companion document to SAE J2763 Test Procedure for Determining Refrigerant Emissions from Mobile Air Conditioning Systems. SAE J2727 estimates system emissions, taking into account production assembly variation and accounts for components that are 100% helium leak tested prior to vehicle final assembly.

J1942/1
The following list consists of hose data provided as of December 2018, and is for convenience in determining acceptability of nonmetallic flexible hose assemblies intended for usage under 46 CFR 56.60-25. Where the maximum allowable working pressure (MAWP) or type of fitting is not specified, use the manufacturer's recommended MAWP or type of fitting. This list has been compiled by SAE Staff from information provided by the manufacturers whose product listings appear in this document. Manufacturers wishing to list their products in this document shall: a. Successfully test their hose to the requirements of SAE J1942, Table 1. b. Submit a letter of certification to the SAE J1942 test requirements for each specific type of hose tested (see sample table on page 4) along with the test results. All sizes should be included in the same letter which must also include all of the information necessary to make a SAE J1942-1 listing. c.

Mechanical and Material Requirements for Externally Threaded Fasteners

2019-11-12
WIP
J429
This SAE Standard covers the mechanical and material requirements for inch-series steel bolts, screws, studs, screws for sems , and U-bolts in sizes to 1-1/2 in. inclusive. The term “stud” as referred to herein applies to a cylindrical rod of moderate length threaded on either one or both ends or throughout its entire length. It does not apply to headed, collared, or similar products which are more closely characterized by requirements shown herein for bolts. The mechanical properties included in Table 1 were compiled at an ambient temperature of approximately 20 °C (68 °F). These properties are valid within a temperature range which depends upon the material grade used and thermal and mechanical processing.

Methods of Measuring Case Depth

2019-11-11
WIP
J423
Case hardening may be defined as a process for hardening a ferrous material in such a manner that the surface layer, known as the case, is substantially harder than the remaining material, known as the core. The process embraces carburizing, nitriding, carbonitriding, cyaniding, induction, and flame hardening. In every instance, chemical composition, mechanical properties, or both are affected by such practice. This testing procedure describes various methods for measuring the depth to which change has been made in either chemical composition or mechanical properties. Each procedure has its own area of application established through proved practice, and no single method is advocated for all purposes. Methods employed for determining the depth of case are either chemical, mechanical, or visual, and the specimens or parts may be subjected to the described test either in the soft or hardened condition.

Electroplating and Related Finishes

2019-11-11
WIP
J474
Electroplating is a process whereby an object is coated with one or more relatively thin, tightly adherent layer of one or more metals. It is accomplished by placing the object to be coated on a plating rack or a fixture, or in a basket or in a rotating container in such a manner that a suitable current may flow through it, and then immersing it in a series of solutions and rinses in planned sequence. The advantage to be gained by electroplating may be considerable; broadly speaking, the process is used when it is desired to endow the basis material (selected for cost, material conservation, and physical property reasons) with surface properties it does not possess. It should be noted that although electroplating is the most widely used process for applying metals to a substrate, they may also be applied by spraying, vacuum deposition, cladding, hot dipping, chemical reduction, mechanical plating, etc.

Hydrogen Embrittlement Testing of Ultra High Strength Steels and Stampings by Acid Immersion

2019-11-07
WIP
J3215
This standard describes a test method for evaluating the susceptibility of cold rolled and hot rolled Ultra High Strength Steels (UHSS) to hydrogen embrittlement. The thickness range of materials that can be evaluated is limited by the ability to bend and strain the material to the specified stress level in the specification. Hydrogen embrittlement can occur with any steel with a tensile strength greater than about 1000 MPa, although some steel microstructures, especially those with retained austenite, may be susceptible at lower tensile strengths under the right conditions. The presence of available hydrogen, high stress levels and materials of high strength are considered the most at risk for hydrogen embrittlement. Due to the specific conditions that need to be present for hydrogen embrittlement to occur, cracking in this test does not indicate that parts made from that material would crack in an automotive environment.

J518/3
This SAE standard outlines general and dimensional specifications for Code 61 flange clamps for use in low pressure applications with J518-1 connections. For port dimensions, port design considerations, and flange head dimensions, please refer to SAE J518-1. The rated working pressure of an assembly shall not exceed the least of all the component working pressure rated values. The following general specifications supplement the dimensional data contained in the tables with respect to all unspecified detail. Parts manufactured to this standard are also compatible with ISO 6162-1 port connections and flange heads.
