ASTM F991 is a standard specification developed by ASTM International that outlines the requirements for the performance and safety of playground equipment. Specifically, it focuses on the impact-absorbing materials used in playground surfaces to reduce the risk of injury from falls. The standard provides guidelines for testing methods and performance criteria to ensure that these materials adequately protect children during play. Compliance with ASTM F991 helps ensure safer play environments in recreational settings.
The ASTM equivalent of DIN 1543 is ASTM A572. Both of these materials are a type of carbon steel.

The ASTM equivalent of DIN 1543 is ASTM A572. Both of these materials are a type of carbon steel.
ASTM B187 and ASTM B152 copper are very similar in structure. The main difference is that ASTM B187 copper is temper H04 and is hard, and ASTM B152 copper is cold rolled and hot rolled.
Astm a36. Its rot rolled steel with nearly matching with astm a36.
Astm a-36
Astm 50
Basically there is no difference as pipe is ussually stenciled with both standards.
