An alternative to wire mesh baskets is a panel with enclosed sides when the:

API 936 allows for the use oftest panels with enclosed sidesinstead of mesh basketswhen the dimensions exceed 18 in. x 18 in. x 4 in.This substitution provides adequate confinement and stability for larger samples during casting and curing, helping maintain uniformity and representative test integrity.

Wire mesh baskets are typically preferred for smaller, lighter samples, but for larger mock-ups or when vibration is involved, fully enclosed forms prevent edge erosion and deformation during casting and handling.
