GSO ISO 506:2023 天然浓缩胶乳 挥发性脂肪酸值的测定

This document specifies a method for the determination of the volatile fatty acid number of natural rubber latex concentrate. The method is not necessarily suitable for latices from natural sources other than Hevea brasiliensis and is not applicable to compounded latex, vulcanized latex, artificial dispersions of rubber or synthetic rubber latices.

GSO ISO 2000:2023 天然橡胶 技术指定橡胶 (TSR) 规格指南

This document specifies guidance on the specification of technically specified rubber (TSR). A grading system is proposed, based on the origin of the natural rubber content and on properties exhibited by the rubber. This document is intended for use by parties involved in the procurement of TSR and is intended to form a basis from which requirements for a particular case may be more closely specified. As such, it describes a number of criteria that need to be the subject of appropriate agreement between the interested parties.

GSO ISO 1409:2023 塑料/橡胶 聚合物分散体和橡胶胶乳（天然和合成） 表面张力的测定

This document specifies two methods for the determination of the surface tension of polymer dispersions and rubber latices (natural and synthetic). — Method A is the ring method (Du Noüy ring method). — Method B is the plate method (Wilhelmy plate method). Method A is suitable valid for polymer dispersions and rubber latices with a viscosity less than 200 mPa·s. Method B is not suitable for polymer dispersions and rubber latices containing cationic surfactants. Methods A and B are also suitable for prevulcanized latices and compounded material. In case of dispute, the preferred method is method A (the ring method).

ASTM D6048-07(2023) 生橡胶、未硫化橡胶化合物和热塑性弹性体的应力松弛试验的标准实施规程

1.1 This practice covers several different techniques for determining the stress relaxation characteristics of rubber and rubberlike materials and for the possible interconversion of this stress relaxation information into dynamic mechanical properties. 1.2 The techniques are intended for materials having stress relaxation moduli in the range of 103 to 108 Pa (0.1 to 1.5 × 104 psi) and for test temperatures from 23 °C to 225 °C (73 °F to 437 °F). Not all measuring apparatus may be able to accommodate the entire ranges. These techniques are also intended for measurement of materials in their rubbery or molten states, or both. 1.3 Differences in results will be found among the techniques. Because of these differences, the test report needs to include the technique and the conditions of the test. This information will allow for resolving any issues pertaining to the test measurements. 1.4 The generalized descriptions of apparatus are based on the measurement of force as a function of time. Mathematical treatment of that relationship produces information that can be representative of material properties. Mathematical transformation of the force measurements will first yield stress relaxation moduli with subsequent transformation producing dynamic mechanical properties. 1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only. 1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the 1 This practice is under the jurisdiction of Committee D11 on Rubber and Rubber-like Materials and is the direct responsibility of Subcommittee D11.12 on Processability Tests.

ASTM D1076-23 橡胶标准规范——浓缩、氨稳定、乳化和离心的天然乳胶

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 µg 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. 1.3 The analytical procedures applicable to the specifications are included and appear in the following order: Section Sampling 6 and 7 Total Solids 8 – 17 Dry Rubber Content 18 Protein Content 19 Total Alkalinity 20 Viscosity 21 Sludge Content 22 Coagulum Content 23 KOH Number 24 pH 25 Mechanical Stability 26 Copper and Manganese 27 Density 28 – 40 Volatile Fatty Acids 41 – 45 Boric Acid 46 Dry Films 47 Precision for All Test Methods 48 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D4827-03(2022) 用毛细管柱气相色谱法测定胶乳中未反应单体含量的标准试验方法

1.1 This test method is for the determination of the unreacted monomer content of acrylic latexes. Monomers that have been successfully determined by this procedure include n-butyl methacrylate, n-butyl acrylate, styrene, and methyl methacrylate. The determination of other monomers has not been evaluated, but this test method is believed to be applicable. The established working range of this test method is from 100 µg ⁄g to 000 µg/g, but there is no reason to believe it will not work outside of this range, provided that appropriate dilutions and adjustments in specimen size are made. 1.2 The unreacted monomer in acrylic latexes is expected to change with time and environmental factors. This time dependence of the determination may be seen as an artificially large deviation of results, making the test method mostly applicable for in-house quality control, where sampling and analysis conditions can be better controlled. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 7. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
