SAE MAM4247B

Click here to purchase
This specification covers an aluminum alloy in the form of hand forgings procured to metric dimensions. AMS 4247 is the inch/pound version of this MAM.

These forgings have been used typically for parts requiring a combination of high strength and resistance to stress-corrosion cracking and for parts requiring stability during machining, but usage is not limited to such applications.

NBBI NB23-2017 Part 2

Click here to purchase
The NBIC recognizes three important areas of post-construction activities where information, understanding,and following specific requirements will promote public and personal safety. These areas include:

  • Installation
  • Inspection
  • Repairs and Alterations

The NBIC provides rules, information, and guidance for post-construction activities, but does not providedetails for all conditions involving pressure-retaining items. Where complete details are not provided in thiscode, the code user is advised to seek guidance from the Jurisdiction and from other technical sources.

The words shall, should, and may are used throughout the NBIC and have the following intent:

  • Shall – action that is mandatory and required.
  • Should – indicates a preferred but not mandatory means to accomplish the requirement unless specifiedby others such as the Jurisdiction.
  • May – permissive, not required or a means to accomplish the specified task.

SAE USCAR12-5

Click here to purchase
SAE USCAR12-5 gives specific and measurable design criteria to be applied at a design review prior to tooling. Thespecification is formatted as a checklist to aid in its use. The requirements do not apply in all situations so engineeringjudgment must be used. This is a specification for design criteria; applicable performance specifications (USCAR-2, etc.)must still be performed.
