GB/T 14449-2017Test method for aerosol products (English PDF)

Foreword

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

This standard replaces GB/T 14449-2008 "aerosol product testing methods," This standard compared with GB/T 14449-2008, in addition to the Code The main technical changes outside the editorial changes are as follows.

--- Revised and supplemented terms and definitions cited;

--- Test content increased the "aerosol can pressure performance, pressure cap sealing cap pressure performance, sealing size" (see 4.1);

--- Increased aerosol can pressure test method (see 5.1.1);

--- Increased aerosol valve fixed cap pressure test method (see 5.1.2);

--- Increasing the sealing size of the test method (see 5.1.3);

--- Prescribed the internal pressure test with the accuracy of the pressure gauge as "not less than 1.6" (see 5.5.1.1);

--- The "method of testing the stability of the content" method (GB/T 1449-2008 5.3) and "container storage resistance test" method (GB/T 1449-2009 in 5.4) merged into "container storability and content stability test" (see 5.2);

--- Modify the spray test method. "Continuous injection 1s" to "net capacity of less than or equal to 400mL, continuous injection 3s; net capacity The amount is greater than 400mL, continuous injection 5s "(see 5.3.1.2, GB/T 14449-2008 5.5.2);

--- Modify the room temperature storage leakage test method. Delete "according to the sample marked injection method to exclude filling operations remain in the valve Propellant or air in the door and/or pipette "(see 5.4.3.2.1, 5.13.2.1 of GB/T 14449-2008);

--- The standard structure has been adjusted.

The flammability test is based on the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria (Fifth Revision) Off aerosol test method technical content, other test methods refer to the American Society for Testing and Materials (ASTM) standards.
