  2. "Parts List" vs. "Bill of Materials" - Eng-Tips

    www.eng-tips.com/viewthread.cfm?qid=113107

    The full definition for the term 'Parts List' taken straight from ASME Y14.34 reads as follows: parts list (PL): a tabulation of all parts and bulk matenals, except those materials that support a process and are not retained, such as cleaning solvents and masking materials, used in the item.

  3. Since a "parts list" often includes bulk materials (like paint, adhesive, sealants, etc.) that are used to produce the part/assembly, or when a "parts list" for a machined component only consists of a single entry describing the raw material used to make the part, a more correct term might be "parts and materials list".

  4. Suppressed items don't appear in the parts lists - Eng-Tips

    Our parts lists are normally driven from the TC BOMView, and output a text file. However, some divisions are moving back towards the automatic drawing parts lists, and one division has just noticed that Suppressed items aren't appearing in the parts list on drawing (even though they would appear in BOMView and on text file parts lists).

  5. Form, fit and function only applies to parts being revised. In your case only the parts list is being revised. Per ASME Y14.100: Items to be deleted shall retain the same Find number. The nomenclature shall be erased and the word "DELETED" inserted in the nomenclature or description column.

  6. You should list the Supplier information (name, address, part number) of the part you are sourcing, including Quality Requirements, Performance Data, interchangability of the part. You need "Source Control Drawing" printed on the drawing, .25" tall. You need 2 general notes:

  7. Is The CAGE Code (DAI) column really still required on modern engineering assembly drawing parts lists? Commercial world and/or Military, most of the books and standards I have say it is a mandatory column in a parts list. My people are talking about eliminating it as we now mostly commercial applications, we really still do some military jobs too.

  8. Pressure Containing vs Pressure Retaining Parts - Eng-Tips

    www.eng-tips.com/viewthread.cfm?qid=195861

    API 674 definition of Pressure-containing parts and the pressure-retaining parts: Clause 1.4.1 7 A pressure-containing part is a part that acts as a barrier between processo r motive fluid and thea tmosphere.

  9. Drawing number the same as part number? Why not? - Eng-Tips

    www.eng-tips.com/viewthread.cfm?qid=239448

    Parts made to drawing rev A should be fully interchangeable with parts made to drawing rev B etc. or else they should have been new part numbers. This is effectively the definition given in ASME Y14.100 of when a new part number is required.

  10. Depending on the complexity of the model, these parts can either be in a part family or modeled as separate parts. Because of the lower scenario, it would make sense for us to store the CAD drawing in a separate item/item revision (option #2 on the left).

  11. Pressure Retaining - Valve engineering - Eng-Tips

    www.eng-tips.com/viewthread.cfm?qid=497603

    Some users require a definite definition between pressure-containing parts and pressure-retaining parts. Regardless of a design code definition of pressure containing or pressure retaining parts, NACE MR0175, in part 1 Clause 5, states that the equipment user shall determine whether or not the service conditions are such that NACE MR0175 ...
