Brake Lining Quality Test Procedure

2019-11-20
WIP
J661
The purpose of this SAE Recommended Practice is to establish a uniform laboratory procedure for securing and reporting the friction and wear characteristics of brake linings. The performance data obtained can be used for in-plant quality control by brake lining manufacturers and for the quality assessment of incoming shipments by the purchasers of brake linings.

Rolling Circumference Index Groups for Agricultural Tractor Drive Tires

2019-11-20
CURRENT
J2523_201911
This SAE Standard is established for the following purpose: a. Simplify the application of drive wheel tires to agricultural vehicles especially those with multiple drive axles having tires of different sizes. b. Provide a pattern to combine similar sized tires into Rolling Circumference Index groups with uniform spacing between groups.

Qualified Hoses for Marine Applications

2019-11-14
WIP
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.

Acrylonitrile Butadiene (Nbr) Rubber, Aromatic Fuel Resistant, 55-65

2019-11-12
WIP
AMS3212R
This specification covers a nitrile (NBR) rubber in the form of sheet, strip, tubing, extrusions, and molded shapes. These products have been used typically for parts, such as gaskets, diaphragms, bushings, grommets, and sleeves, requiring resistance to aromatic and aliphatic fuels when continuously or alternately exposed to both, but usage is not limited to such applications.

Procedure for Inspection of In-Service Airborne Accumulators for Corrosion and Damage

2019-11-12
CURRENT
ARP4150A
This SAE Aerospace Recommended Practice (ARP) is a guide in establishing inspection procedures to determine the condition of in-service accumulators. Recommendations are also provided for corrective action if it is determined that the environment is contributing to the deterioration of the surface protection system treatments.

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.

Anodized Aluminum Automotive Parts

2019-11-11
WIP
J399
Automotive parts can be fabricated from either coiled sheet, flat sheet or extruded shapes. Alloy selection is governed by finish requirements, forming characteristics, and mechanical properties. Bright anodizing alloys 5657 and 5252 sheet provide a high luster and are preferred for trim which can be formed from an intermediate temper, such as H25. Bright anodizing alloy 5457 is used for parts which require high elongation and a fully annealed ('0') temper. Alloy 6463 is a medium strength bright anodizing extrusion alloy; Alloy X7016 is a high strength bright anodizing extrusion alloy primarily suited for bumper applications. To satisfy anti-glare requirements for certain trim applications, sheet alloy 5205 and extrusion alloy 6063 are capable of providing the desired low-gloss anodized finish.

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.
