BS8888 and Hatch Patterns

Hello

I have a question on sectional arrangements and hatching. Drawing mechanical components, in a section view what is the standard for hatching in BS8888. The reason I ask is that we are sectioning a part in aluminum and the listed hatch pattern is ANSI38. This is essentially a cross hatch pattern with broken and staggered lines in one of the directions. When applied to the drawing view it make the lines look a little unclear, so I am keen to check on what is the standard when working to BS8888. I would like to stick to the standards where possible. Usually the materials are steel or iron, which are a much planer hatch in continuous lines and so don't have negative impact on the clarity of the details.

Appreciate any guidance from the community. clipping attached.

Kind regards

David

Generally your job is to create drawing that is legible, so if hatch pattern is getting in the way, drop it.
Unfortunately I cannot provide reference to standard number, but if memory serves, general-purpose hatch can substitute material-related one.
