points and having a capacity not exceeding 150 l;
-
.2 receptacles of different dimensions with the
exception of cylinders in conformity with 2.1 having a capacity of
not less than 100 l and not more than 1,000 l and
whether or not fitted with hoisting devices of sufficient strength;
and

.3 assemblies, known as "frames", of cylinders
in conformity with 2.1, the cylinders being interconnected by a manifold
within the frame and held firmly together by metal fittings. The frames
are equipped with securing and handling devices of sufficient strength
(e.g. cylindrical receptacles are equipped with rolling hoops and
