Basic dataStandard ID: GB/T 1034-2008 (GB/T1034-2008)Description (Translated English): Plastics -- Determination of water absorption Sector / Industry: National Standard (Recommended) Classification of Chinese Standard: G31 Classification of International Standard: 83.080.01 Word Count Estimation: 16,174 Date of Issue: 2008-08-04 Date of Implementation: 2009-04-01 Older Standard (superseded by this standard): GB/T 1034-1998 Quoted Standard: GB/T 11547-2008; GB/T 17037.3-2003; ISO 2818-1994 Adopted Standard: ISO 62-2008, IDT Regulation (derived from): National Standard Approval Announcement 2008 No.14 (Total No.127) Issuing agency(ies): General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, Standardization Administration of the People's Republic of China Summary: This standard specifies the determination of flat or curved shape of the solid plastic water absorption method in the thickness direction. This standard also specifies that when the sample is immersed in water or under certain conditions of humidity, water absorption plastic measuring predetermined sample size. Single- phase material is assumed to have a constant Fick diffusion behavior of water absorption by the sample thickness direction, the direction can be determined by the thickness of the moisture diffusion coefficient. The model of homogeneous material and reinforced polymeric materials below the glass transition temperature of the test is valid. However, some two-phase base material, such as epoxy curing may require multiphase absorption model, not included in the scope of this standard. Absorbent material and (or) diffusion coefficient of water absorption of the plastic is exposed to relatively balanced condition for the same.

Determination of water absorption ICS 83.080.01 G31 National Standards of People's Republic of China GB/T 1034-2008/ISO 62.2008 Replacing GB/T 1034-1998 Plastics - Determination of water absorption (ISO 62.2008, IDT) Posted 2008-08-04 2009-04-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released ForewordThis standard is identical with ISO 62.2008 "Plastics - Determination of water absorption ---" (in English). This standard is equivalent translation ISO 62.2008. This standard replaces GB/T 1034-1998 "Test method for water absorption of plastic." This standard and GB/T 1034-1998 The main differences are as follows. --- Increased introduction; --- Quality of the sample by the measurement accuracy of 1mg to 0.1mg (Chapter 4); --- GB/T 1034-1998 in Test Method 2 and 4 of this standard consolidation method 3; test temperature range from room temperature to 23.0 ℃ ± 0.5 ℃ to 23.0 ℃ ± 1.0 ℃ or 23.0 ℃ ± 2.0 ℃, humidity increased from 50% to 50% ± 5% or 50% ± 10% (Chapter 6); --- Increased law of diffusion measured by Fick (Fick) Saturated water absorption and diffusion coefficients (Chapter 7) in the result representation; --- Added Appendix A. Verify Correlation water absorption of the sample and Fick (Fick) law of diffusion; --- Added Appendix B. ISO 62.2008 Appendix B describes about precision; --- Added Appendix C. The main difference between this standard and GB/T 1034-1998 sample. This standard Annex A, Annex B and Annex C is informative appendix. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee of plastic (SAC/TC15) centralized. plastic. Method 2 does not apply to not keep in shape after immersion in boiling water plastic (see 6.4).2 Normative referencesThe following documents contain provisions which, through reference in this standard to become the standard terms. For dated references, all subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to study under this agreement is standard Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.

If necessary, Determination of water loss after drying the sample in addition to water. In some applications, you need to use a relative humidity of 70% to 90% and 70 ℃ ~ 90 ℃ conditions. Interested parties may negotiate to use than the present standard Motion recommends a higher temperature and humidity. When using a different recommended relative humidity and temperature, should be fully described in the test report (including the phase Should tolerances).4 Instrument4.1 Balances Accuracy of ± 0.1mg (see 6.1.3). 4.2 Oven Has forced convection or vacuum system can be controlled at 50.0 ℃ ± 2.0 ℃ or other agreed temperature oven (see 6.1.2).
