testing static member - thread safe?

If many thread needs to test if one field of static class is null,

if (StaticClass.fieldA == null)

will it be thread safe and doesn't need thread synchronization?

Only if fieldA is either readonly (and initialized as part of the
class initialization for StaticClass) or volatile.

Otherwise you could end up seeing "stale" values.
