A105 Supplementary Requirement S5

A105 Supplementary Requirement S5

A105 Supplementary Requirement S5


I have a customer that is asking us to purchase material that complies with ASTM A105 supplementary requirement S5.

We are an ASME shop and normally only handle ASME specs. ASME BPVC IIA 2019 states that it matches A105-05, and there is no supplementary requirement S5.

Can anyone that has access to ASTM specs confirm when this supplementary requirement came into existence?

Thank you,

RE: A105 Supplementary Requirement S5

Maybe S5 is part of a reference spec...A-266?

RE: A105 Supplementary Requirement S5

I have copies of A105A105M-14 and A105A105M-18 (which seems current); S5 is in neither.
It doesnt make sense to refer to S5 if it isnt part of A105; that means one should start guessing.

S5 is found in A788A788M, A696, A675A675M and A266A266M.

RE: A105 Supplementary Requirement S5

Thanks guys. The customer is clearly stating A105 S5, time to ask them where they're referring to...

White Paper - The Criticality of the E/E Architecture
Modern vehicles are highly sophisticated systems incorporating electrical, electronic, software and mechanical components. Mechanical systems are giving way to advanced software and electronic devices, driving automakers to innovate and differentiate their vehicles via the electric and electronic (E/E) architecture. As the pace of change accelerates, automotive companies need to evolve their development processes to deliver and maximize the value of these architectures. Download Now
White Paper - Model Based Engineering for Wire Harness Manufacturing
Modern cars, trucks, and other vehicles feature an ever-increasing number of sophisticated electrical and electronic features, placing a larger burden on the wiring harness that enables these new features. As complexity rises, current harness manufacturing methods are struggling to keep pace due to manual data exchanges and the inability to capture tribal knowledge. A model-based wire harness manufacturing engineering flow automates data exchange and captures tribal knowledge through design rules to help harness manufacturers improve harness quality and boost efficiency.

White Paper - Modeling and Optimizing Wire Harness Costs for Variation Complexity
This paper will focus on the quantification of the complexity related costs in harness variations in order to model them, allowing automated algorithms to optimize for these costs. A number of real world examples will be provided as well. Since no two businesses are alike, it is the aim of this paper to provide the foundational knowledge and methodology so the reader can assess their own business to model how variation complexity costs affect their business.
