Scope

1.1 This specification covers requirements for first grade concentrated natural rubber latex (see Table 1) of the following types:

Type 1-Centrifuged natural latex preserved with ammonia only or by formaldehyde followed by ammonia.

Type 2-Creamed natural latex preserved with ammonia only or by formaldehyde followed by ammonia.

Type 3-Centrifuged natural latex preserved with low ammonia with other necessary preservatives.

1.2 This specification is not necessarily applicable to latices prepared or preserved by other methods, and shall not be construed as limiting the desirability or usefulness of other types of latices. It does not apply to natural latex sources other than Hevea braziliensisnor to compounded latex concentrates.
