Grade
Description of RSS as per Green Book.
RSS1: The grade must be produced under conditions
where all processing operations are carefully and uniformly
controlled. Each bale must be packed free of moulds but
very slight traces of dry mould on wrappers or bale surfaces
adjacent to wrapper found at the time of delivery will not
be objected to, provided there is no penetration of mould
inside the bale. Oxidized spots or streaks, weak, heated,
under cured, and over smoked, opaque and burnt sheets are
not permissible.
The rubber must be dry, clean, strong and evenly smoked
and free from blemishes, specks, rust, blisters, sand, dirty
packing and any other foreign matter. Small pinhead bubbles
if scattered, will not be objected to
RSS 2: Slight rust or a slight amount of dry mould
on wrappers, bale surfaces and interior sheets, found at
the time of delivery, will not be objected to, provided
these, either singly or in combination, do not exist in
more than 5% of the number of bales included in the delivery,
lot or tender as determined by the number of bales inspected.
Small bubbles and slight specks of bark, if scattered, will
not be objected to.
Oxidized spots or streaks, weak, heated, under cured, and
over smoked, opaque and burnt sheets are ruled out. The
rubber must be dry, clean strong and free from blemishes,
blisters, sand, dirty packing and all other foreign matter
other than specified above as permissible.
RSS3: Rust and dry mould on wrappers, bale surfaces
and interior sheets, found at the time of delivery, will
not be objected to, provided these conditions either singly
or in combination do not exist to an objectionable extent
on or in more than 10% of the number of bales included in
the delivery, lot or tender as determined by the number
of bales inspected. Slight blemishes in color, small bubbles
and small specks of bark are permissible. The other parameters
are the same as for RSS 2
RSS4: Rust, dry mould on wrappers, bale surfaces
and interior sheets, found at time of delivery, will not
be objected to provide these conditions, either singly or
in combination, do not exist to an objectionable extent
on or in more than 20% of the number of bales included in
the delivery, lot or tender as determined by the number
of bales inspected.
RSS5: Rust, dry mould on wrappers, bale surfaces
and interior sheets, found at the time of delivery will
not be objected to provided these conditions, either singly
or in combination, do not exist to an objectionable extent
on or in more than 30 % of the number of bales.
Large bark particles, bubbles and small blisters, stains,
over smoked, slightly sticky rubber and small blemishes
are permissible proved they are not present to a marked
degree. Slightly under cured rubber is also permissible
but not weak, heated, burnt rubber, and those with oxidized
spots or streaks. The rubber must be dry, firm, and free
of sand, dirty packing and other foreign matter other than
specified above as permissible.
