Class tells you how it protects you. Type tells you how it's used. Section 4.1 lists the equipment covered, each with the book's own examples.

(j)Electrical installations in office furnitureBS 6396; 4.1.1 (p.35) covers furniture with built-in electrics
✋“Portable” is not one of the types. The word survives in “PAT”, but the list in 4.1 doesn't use it.
Things can fit more than one type, and that's fine. Pick the one that best describes how the item is used.

Two good edge cases

1A robot vacuum
The robot moves about, but its charging dock is what plugs into the supply — that's the part you inspect and test.
2A cordless drill
Batteries are generally outside the scope (4.4.1). You still look the drill and battery over, and you test the charger.
