SAE/USCAR-45 defines test methods and performance requirements for ultrasonically-welded wire-to-wire splices for automotive applications. Face-to-face, butt splice, and center strip configurations per Figure 1 can be tested. The tests defined in this specification subject samples on test to stresses that simulate a lifetime of exposure for a road vehicle. Stresses called out in this specification include thermal shock, temperature/humidity cycling and mechanical stress from different directions.

This document gives specific and measurable design criteria to be applied at a design review prior to tooling. The specification is formatted as a checklist to aid in its use. The requirements do not apply in all situations so engineering judgment must be used. This is a specification for design criteria; applicable performance specifications (USCAR-2, etc.) must still be performed. Items in this document are grouped by component as follows: A Terminals B Secondary Terminal Locks C Connectors D Connector Locks E Secondary Connector Locks (Connector Position Assurance, CPA) F Connector Seals G Serviceability H High Voltage (≥60V) Application Requirements I Drawing and General Requirements

This International Standard specifies the dimensions, test methods, and requirements for single core 60 V cables intended for use in road vehicle applications where the nominal system voltage is ≤ (60 V DC or 25 V AC). It also specifies additional test methods and/or requirements for 600 V cables intended for use in road vehicle applications where the nominal system voltage is > (60 V DC or 25 V AC) to ≤ (600 V DC or 600 V AC). It also applies to individual cores in multi-core cables. See ISO 6722 for “Temperature Class Ratings”.

This specification describes a method and acceptance criteria for testing automotive wire harness retainer clips. Retainer clips are plastic parts that hold a wire harness or electrical connector in a specific position. Typical plastic retainers work by having a set of “branches” that can be inserted into a hole sized to be easy to install but provide acceptable retention. This specification tests retainer clips for mechanical retention when exposed to the mechanical and environmental stresses typically found in automotive applications over a 15-year service life. This specification has several test options to allow the test to match to the expected service conditions. The variability of applications typically arises a) from different ambient temperatures near the clip, different proximity to automotive fluids, different exposure to standing water or water spray and different thicknesses of the holes that the clip is inserted into.

This document is a supplement to SAE/USCAR 17 and is intended to give recommended usages for one and two-way RF connectors and dimensional requirements for 2-way RF connectors and hybrid (RF & DC power) connectors which are not currently specified elsewhere. The radio frequency (RF) connector interface specified herein is suited for unsealed and sealed automobile applications up to 6 GHz and is intended for in-line, board mount, device mount, straight or angled applications. Dimensional requirements are specified in this document to ensure interchangeability. Compliance with the dimensional requirements of this specification will not guarantee interoperability between different suppliers mating connectors. It is the supplier responsibility to ensure RF performance requirements are met with other suppliers mating connectors. Performance requirements are specified in SAE/USCAR-2, and in SAE/USCAR-17.

This specification defines test methods and performance criteria for evaluating ultrasonically welded wire-to-terminal metallurgical bonds. The examples used are specific to the linear weld type of process equipment. USCAR-38 is not applicable for “Splice Welding”. The specification is applicable to wire-on-pad configurations with a typical weld shown in Figure 1. This test specification subjects parts under test to environmental exposures to simulate a lifetime of field exposure for a road vehicle. Exposures called-out in this specification include Thermal Shock, Temperature Humidity Cycling and mechanical abuse. This test specification is intended to evaluate the strength and performance of the interface between wires to an electrical terminal. Validation of the performance of the Terminal is a separate task and can be accomplished using a component validation test such as SAE/USCAR-2, which evaluates whether the entire connection system is acceptable.

This document describes the design relative to assembly force, and hand clearance guidelines for conventional hand-plug, mechanical assist and twist lock electrical connectors, as well as Connector Position Assurances (CPAs). The minimum values associated with this design guide need to be evaluated against other critical characteristics that impact quality, efficiency and other traits of assembly feasibility. All possible designs and applications could not be anticipated in creating these guidelines. Where there are questions of adherence to this document, such as use of an “off-the-shelf” design, always consult the responsible Ergonomics Department.

This guideline is applicable to existing lead solder production products that will change to lead-free solder processes to meet the ELV Directive 2000/53/EC Annex II, exemption 8B requirements. This guideline is applicable to similar products used by multiple OEM's that have the same manufacturing processes / equipment. The intent is to streamline the supplier’s environmental testing via common qualification to reduce timing, quantities, and costs.

This document describes the design and assembly force guidelines for conventional shipping caps, torque caps, and body plugs. All possible design and applications could not be anticipated in creating these guidelines.

This document describes the assessment methods and physical requirements associated with the manual handling of carts and dollies, specific to material handling systems. All possible designs and applications could not be anticipated in creating these guidelines. Where there are questions of adherence to this document, such as use of an “off-the shelf” design, always consult the responsible Ergonomics Department. Force guidelines were primarily developed referencing the push/pull psychophysical Snook data contained in A Guide to Manual Materials Handling (second edition) by Mital, Nicholson and Ayoub (NY: Taylor & Francis, 1997). The force guidelines accommodate 75% of female capabilities and 99% of male capabilities. Factors that were included in the established guideline include: push / pull distances, vertical hand height, horizontal hand height, frequency and wheel / castor alignment and load rating. These factors were used to develop a conservative force guideline.

This document describes the design, assessment methods and physical requirements associated with material handling systems. This would include, but not limited to manual dollies, small lot systems and kitting. All possible designs and applications could not be anticipated in creating these guidelines.

This specification defines test methods and requirements for validation of solderless crimped connections. The purpose of this test is to simulate in the lab the stress seen in a typical life (15 years and 150,000 miles) for a crimp connection and assure the crimp is mechanically strong and electrically stable. This specification was developed for use with stranded automotive copper wire. Only where specifically mentioned are other constructions or other core materials (aluminum, clad, steel core, etc.) applicable. This specification does not apply to wire types not mentioned. This specification is based on accepted levels of environmental exposure for automotive applications.

This standard is a full performance specification, it includes dimensional and operational parameters as well as performance characteristics which must be met when submitting a cigar lighter assembly or power outlet assembly for production approval. This standard constitutes an acceptance specification for a surface mounted, front-loaded cigar lighter or power outlet.

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.
