GB/T 35489-2017Guide to the selection of ageing conditions for adhesives (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses redrafted Law Amendment using ISO 9142:2003 "adhesive bonding specimen standard laboratory aging conditions selection guide".

This standard and ISO 9142:2003 technical differences and the reasons are as follows.

--- On normative references, this standard made a technical difference with the adjustment to adapt to China's technical conditions, adjust the situation Concentration reflected in the second chapter "Normative references", the specific adjustments are as follows.

- Replacing ISO 175:1999 with International Standard GB/T 11547 modified.

- Equivalent to the international standard GB/T 2918 instead of ISO 291:1997.

- Equivalent to the international standard GB/T 7124 instead of ISO 4587:2003.

- The ISO 4588:1995 referenced in ISO 9142:2003 has been deleted.

- GB/T 16422 (all parts) instead of ISO 4892 (all parts), the degree of consistency between the various parts of the two standards as follows.

- GB/T 16422.1-2006 plastic laboratory exposure test methods - Part 1. General (ISO 4892-1:1999, IDT);

- GB/T 16422.2-2014 plastic laboratory exposure test methods - Part 2. Xenon arc lamp (ISO 4892-2:2006, IDT);

- GB/T 16422.3-2014 plastic laboratory exposure test methods - Part 3. Fluorescent UV lamp (ISO 4892-3:2006, IDT);

- GB/T 16422.4-2014 plastic laboratory exposure test methods - Part 4. Open carbon arc lamp (ISO 4892-4:2004, IDT).

- Equivalent to the use of international standards GB/T 10125-1997 instead of ISO 9227:1990.

- increase the reference GB/T 16997.

- increase the reference GB/T 21526.

--- Added Chapter 8 c) Record aging rate and type of damage. The aging test results described more perfect, easy to understand.

This standard made the following editorial changes.

--- Modify the standard name "adhesive aging conditions guide." this standard proposed by the China Petroleum and Chemical Industry Federation.

This standard by the National Standardization Technical Committee adhesives (SAC/TC185) centralized.

This standard was drafted unit. Shanghai Rubber Products Co., Ltd., Suzhou giant to help new materials Technology Co., Ltd., Jiangsu black pine adhesion Pharmaceutical Co., Ltd., Guangzhou Baiyun Chemical Industry Co., Ltd.

1 Scope

This standard gives the adhesive in the standard laboratory conditions, the aging of a variety of state selection guide.

This standard applies to assess the aging environment (climate or chemistry) on the impact of adhesive bonding.

The results obtained using this standard can not be used for the determination of the service life of adhesive.

It is recommended that the aging conditions be best related to the particular application of the adhesive.
