This International Standard specifies a method for the determination of the bound acrylonitrile content of emulsion-polymerized NBR latices having a bound acrylonitrile content, expressed as a percentage of the polymer content, of between 18% and 45%. The method is also applicable to, for example, carboxylic-nitrile-butadiene (XNBR) latices and nitrile-isoprene (NIR) latices. NOTE 1 The determination includes any water-insoluble nitrogen-containing additives present in the latex.

This International Standard specifies a ring method for the determination of the surface tension of polymer dispersions and rubber latices (natural and synthetic). The method is valid for polymer dispersions and rub-ber latices with a viscosity less than 200 mPa·s. To achieve this, the dispersion or latex is diluted with water to a total solids content of 40 % (m/m). If nec-essary, the solids content is further reduced to ensure that the viscosity is under the specified limit. The method is also suitable for prevulcanized latices and compounded materials.

This International Standard specifies a method for the determination of the KOH number of natural rubber latex concentrate which is preserved wholly or in part with ammonia. The method is applicable to latices containing boric acid. The method is not applicable to latices preserved with potassium hydroxide. It is not necessarily suitable for latices from natural sources other than Hevea brasiliensis, or for latices of syn-thetic rubber, compounded latex, vulcanized latex or artificial dispersions of rubber.

This International Standard specifies a method for the determination of the dry rubber content of natural rub-ber latex concentrate. The method is not necessarily suitable for latices from natural sources other than Hevea brasiliensis, or for compounded latex, vulcanized latex or artificial disper-sions of rubber, and is not applicable to synthetic rub-ber latices.

This test method is designed to broaden the scope of the previous edition of the test method by the inclusion of tall oil and tall oil derived from products as test materials. Test Methods D 803 currently includes a method for the determination of unsaponifiable matter. The amount of unsaponifiable matter in tall oil and other related products is important in characterizing such products as it indicates the level of nonacidic material, both free and combined, present in the test material. The unsaponifiable in naval stores products is primarily composed of higher molecular weight alcohols, sterols, and hydrocarbons.1.1 This test method covers the determination of the percentage of material in Naval Stores products as defined in Terminology D 804 including rosin, tall oil and related products, other than insoluble dirt or similar visible foreign matter that does not yield a water-soluble soap when the sample is saponified with potassium hydroxide.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

These test methods are designed to broaden the scope of the previous edition of these test methods by the inclusion of tall oil as a test material. Test Methods D803 currently includes methods for the determination of the rosin acid and fatty acid content of crude tall oil. Test Methods D803 references Test Method D1585. Rosin and tall oil are composed primarily of rosin acids and fatty acids, and the measurement of these components is important in establishing the composition of these materials.1.1 These test methods cover the determination of the fatty acids of naval stores, including rosin, tall oil, and related products. 1.2 These test methods may not be applicable to adducts or derivatives of rosin or other naval stores products. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
