GB/T 23984-2009Paints and varnishes -- Determination of the volatile organic compound content of low-VOC emulsion paints (in-can VOC) (English PDF)

Foreword

This standard is equivalent to international standards ISO 17895:2005 "Paints and varnishes --- low VOC latex paint volatile organic compounds Determination (tank VOC) content "(in English).

This standard is equivalent translation ISO 17895:2005.

For ease of use, this standard editorial changes as follows.

--- Use the "standard" instead of "this International Standard";

--- Delete international standards foreword.

Appendix A of this standard is an informative annex.

The standard proposed by China Petroleum and Chemical Industry Association.

This standard by the National Standardization Technical Committee paint pigment.

This standard was drafted. CNOOC Changzhou coating Chemical Research Institute, Nippon Paint (China) Co., Ltd. Kunshan City, the world scientific and technical development has Limited.

1 Scope

This standard specifies the determination (101.325kPa) low VOC latex paint volatile at normal atmospheric pressure using gas chromatography Organic compound (VOC) (tank VOC) content (i.e., the highest boiling point up to 250 °C organic compound content) of the method. This method Applicable VOC content between samples (mass fraction) from 0.01% to 0.1%.

The main purpose of this method is to determine whether a product is low VOC paint, instead of routine quality control.

3 Terms and Definitions

The following terms and definitions apply to this standard.

At normal temperature and pressure of the environment, to the natural evaporation of any organic liquid or a solid.

Note 1. The term VOC coatings currently used in the field, see the volatile organic compound content (VOC content).

Note 2. The US government law, VOC refers to those compounds having only photochemical activity in the atmosphere (see ASTMD3960). And any other Compounds are defined as exempt compound.

[See ISO 4618].

Mass of volatile organic compounds under the conditions specified in the measured coatings exist.

Note. The nature and quantity of the considered compound depends on the field of coating applications. For every application, limit values and a measurement or calculation method, by the rule 1) or the provisions agreed.

1) the rules of this standard is adopted 1996-01-06 European Commission Decision 96/13/EC of the definition. the standard atmospheric pressure (101.325kPa) , The boiling point (or initial boiling point) does not exceed 250 °C all organic compounds are volatile organic compounds (VOCS).

[See ISO 4618].
