This guide details the standard methods suitable for testing latex vehicles. Included here are methods for latex sampling, nonvolatile content, minimum film formation temperature, qualitative polymeric analysis, density, viscosity, consistency, water content, pH, and surface tension.1.1 This guide covers methods suitable for testing latex vehicles. Certain of these methods were developed expressly for testing latex vehicles (Table 1). Others were developed for testing or analyzing formulated water- or solvent-based coatings but would be equally applicable for testing latices.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 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.

5.1 Latex paints are sometimes applied over substrates that contain a high level of water-soluble salts that results in efflorescence. This practice evaluates a coating’s vulnerability to efflorescence.1.1 This practice covers the evaluation of the degree to which a latex paint resists the formation of efflorescence and alkali burnout on the exposed paint surface.1.2 This practice is designed primarily to relate efflorescence originating in the substrate to the deposit appearing on the surface of latex paints. This practice relates chiefly to the painting of masonry-type substrates such as concrete block, brick, mortar, stucco, poured concrete, and similar materials.1.3 The values in SI units are to be regarded as the standard. The values in parentheses are for information only.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.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.

1.1 This performance specification covers mixtures of water-based latex polymer, mineral aggregates, and optional other admixtures that, when combined, create a weather-protective and aliphatic hydrocarbon-resistant coating over asphalt and other pavements. There are two variations of the coating (Class 1 and Class 2): Class 1, a standard version—typically black but can be other colors, and Class 2, designed to be a solar reflective version.1.2 Units—The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.1.3 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements for the 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.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.

4.1 Weakening of natural rubber latex is known to occur after contact with certain lubricants, particularly petroleum-based products.3,4 This procedure was developed as a screening method for lubricant manufacturers to determine whether or not a particular personal lubricant has a significant effect on the tensile and airburst properties of an NRL condom.4.2 This test method is designed for use on NRL condoms that meet the criteria of Specification D3492 and can: (1) have a ring specimen cut in compliance with Appendix X1 of Specification D3492 and (2) be tested for burst properties in compliance with Annex A2 of Specification D3492.4.3 This test method is not to be used to determine the safety of either the test lubricant or NRL condom. This test method is to be used only to determine if the tensile or airburst properties of the NRL condom have been significantly affected by the test lubricant.1.1 This test method covers procedures used to detect a shift in physical properties of natural rubber latex (NRL) condoms after immersion in a personal lubricant. “Personal lubricants” are lubricants such as liquids or gels that are applied by the consumer at the time of condom use.1.2 This test method does not attempt to address compatibility of lubricants applied to a condom at the time of manufacture (“manufacturer lubricants”). It shall be the responsibility of the condom manufacturer to verify the long-term stability (shelf life) of any manufacturer lubricant that is packaged within the individual condom wrapper. Other regulatory requirements may apply.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.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.

1.1 This specification covers dipped goods and coatings made from compounded latex. Products manufactured from this material include boots, coated clips, coated sponge parts, and coated fabrics for automotive applications.1.2 The compounds listed in Tables 1 and 2 are grouped in classifications based primarily on physical properties, which are prescribed in the tables. These values, together with any additional requirements indicated by suffix letters in the grade designations as described in Section 2, define the properties of the compounds after vulcanization. These values apply to test specimens obtained from standard laboratory-dipped films prepared in accordance with procedures described in the applicable ASTM methods. Test results from finished products may not duplicate the values obtained from standard test films. When differences due to the difficulty in obtaining suitable test specimens from the finished part arise, the purchaser and the supplier may agree on acceptable deviations. This can be done by comparing results obtained on standard test films with those obtained on actual parts.1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

5.1 This test method measures the initial filtration efficiency of materials by sampling representative volumes of the upstream and downstream latex aerosol concentrations in a controlled airflow chamber.5.2 This test method provides specific test techniques for both manufacturers and users to evaluate materials when exposed to aerosol particle sizes between 0.1 and 5.0 μm.5.2.1 This test method establishes a basis of efficiency comparison between materials.1.1 This test method establishes procedures for measuring the initial particle filtration efficiency of materials using monodispersed aerosols.1.1.1 This test method utilizes light-scattering particle counting in the size range of 0.1 to 5.0 μm and airflow test velocities of 0.5 to 25 cm/s.1.2 The test procedure measures filtration efficiency by comparing the particle count in the feed stream (upstream) to that in the filtrate (downstream).1.3 The values stated in SI units or in other units shall be regarded separately as standard. The values stated in each system must be used independently of the other, without combining values in any way.1.4 The following precautionary caveat pertains only to the test methods portion, Section 10, of this specification. 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.1.5 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.

This test method provides no absolute information, rather ranking only of the selected series of paints.This test method can provide a pass-fail situation if known acceptable and unacceptable paints are included in the test.1.1 This test method covers the determination of the comparative coalescence of a series of latex paints by determining the porosity of films dried at standard and at low temperature. Porosity is evaluated with a penetrating medium as in Test Method D 3258.1.2 The texture of the film, which can affect cleanup, will influence the results of the test. Stain applied to a high-hiding paint will not lower the reflectance as much as the same stain applied to a low-hiding paint of equal porosity. These points must be considered in comparing the different paints.1.3 This method should be used only for comparative testing within one laboratory, as the numerical results obtained by different laboratories do not usually agree.1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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.
