]]> In the process of making corrugated board, there are several steps in the process that require precise applications of pressure between rolls, or consistent gaps between rolls in order to meter precise amounts of adhesive to the flutes. In order for these requirements to be met, rolls have to be parallel to each other and also must be as close to perfectly round as possible.

If a pressure roll is not perfectly round, then as the roll turns against the corrugating roll there will be areas where the pressure applied to the singlefacer web at the rolls' nip point will be lessened. If the pressure is lessened enough, the singlefacer bond can be compromised and, thus, affect board quality. An adjustment to increase pressure to compensate for the problem could lead to another problem-pressure roll cutting of the medium and possibly box failure in compression and/or mullen (burst).

SNZ 1985-09-29 23
]]> Specifies a range of pipe threads from 1/16 to 6 for pressure-tight joints together with thread forms, dimensions and tolerances, and designations. Includes appendices for recommended gauging systems and methods of use of gauges. Requirements are given for jointing threads for taper external threads, taper or parallel internal threads and for long-screw threads for long-screws specified in BS 1387.

Published By Publication Date Number of Pages
SAE 2020-11-19 7
]]>
This standard outlines test methods and practices which can detect embrittlement of steel parts. It is a process control or referee verification test. The risk of embrittlement of steel is minimized by using best practices in the finishing/coating process. One such practice is described in SAE/USCAR-5, Avoidance of Hydrogen Embrittlement of Steel.

SAE 2019-03-14 14
]]> This specification covers the grain flow pattern requirements in headed bolts, screws, and studs. The heading practice in the manufacture of the bolt, screw, or stud sets the grain flow pattern, but it is also greatly influenced by the fastener design.

Published By Publication Date Number of Pages
SAE 2021-05-13 16
]]>
This specification defines the dimensional and performance requirements for aftermarket spin-on oil filters intended for use on gasoline engines. Filters meeting this specification may also be suitable for use on some diesel applications.
Filters meeting these dimensional limits are intended to meet the oil filter fit and package requirements for engine and vehicle designs.
Filters meeting the performance requirements are intended to maintain sufficient durability to support typical 10000 mile oil change intervals. Some OEM engines may require special filters for which this specification would not support.
Filters that meet or exceed this specification requirements for both dimensional and performance can claim “Conformance to SAE/USCAR – 36 Specifications.” Filters that meet just the performance specifications (ie. may have different thread) can claim “Aligns to SAE/USCAR – 36 Performance Specifications.”

Published By Publication Date Number of Pages
SAE 2020-11-19 14
]]>
A bolt-load retention (BLR) test is a practical test to determine the bolt load of a fastener joint with time and at given temperatures. There are three types of BLR tests described in this standard, namely general-purpose test, design-purpose test, and screening material test. A general-purpose BLR test may be used for screening materials, while a design-purpose BLR test is usually used to verify the BLR behavior of a specific joint. The screening material test is an example of the general-purpose test for typical automotive applications.

Published By Publication Date Number of Pages
SAE 2003-09-18 10
]]>
This test procedure is intended to evaluate and/or validate electrical ground schemes for use on the body or chassis. There are two classes based on the expected environmental conditions. Exposed Grounds can be located anywhere in the vehicle (except on the powertrain) and is the class for which most schemes should be tested. Unexposed Grounds can only be used in the passenger compartment or trunk and as such are special cases.
This procedure as written is not intended for testing powertrain grounds where high temperatures and vibration levels may be encountered. These situations may require modifications to this procedure and are left to the Responsible Engineer to determine.
This specification does not specifically address validation of terminal to wire electrical crimps. Crimps are tested to SAE/USCAR-21

This standard provides a test method for determining the torque-tension relationship of a fastener finish as applied to a surrogate screw for the purpose of measuring the frictional characteristic of the fastener finish. The results obtained by this test shall be used as a process control attribute of the fastener finish and shall not be utilized for specific applications.
