Both 60065 and 60950 have specific requirements for materials and Type Tests where the case is used for protection from shock and/or to prevent spread of fire.
UL1310 and CSA 223 are very similar and are for Class '2' power supplies - which seems to peculiar to North American code. Section 47 of UL1310 addresses requirements for thermoplastic enclosures.
