Full Description
1.1''This specification covers requirements for first grade concentrated natural rubber latex (see Table 1) of the following categories:
Category 1'''Centrifuged Hevea natural latex stabilized with ammonia only.
Category 2'''Creamed Hevea natural latex stabilized with ammonia only.
Category 3'''Centrifuged Hevea natural latex stabilized with low ammonia.
Category 4'''Centrifuged, or centrifuged and creamed, guayule latex, or other natural rubber latex, containing less than 200 ''g total protein per gram dry weight of latex, with ammonia or other hydroxide.
Category 5'''Centrifuged Hevea natural latex treated with aluminum hydroxide or by other means, stabilized with ammonia only containing less than 0.5 % non-rubber content.
1.2''This specification is not necessarily applicable to latices prepared, stabilized, or preserved by other methods, and shall not be construed as limiting the desirability or usefulness of other categories of latices. It does apply to natural latex sources other than Hevea brasiliensis but does not apply to compounded latex concentrates.
