Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 17939-2008 "nuclear grade HEPA filter," compared with the GB/T 17939-2008 major technological changes
as follows.
--- Modify the scope for nuclear and radiation facilities in air and gas handling systems used in nuclear grade HEPA filter
(See Chapter 1, Chapter 1 of the 2008 edition);
--- Modify the "Terms and definitions" (see Chapter 3, Section 3 of the 2008 edition);
--- Revised "classification and specifications" split "classification", "Specifications" (see Chapter 4, Chapter 4, 2008 edition of Chapter 5);
--- Added "classification principle" (see 4.1);
--- Modify the "nuclear partakers HEPA air filters" to "partition plate nuclear grade HEPA filter," "nuclear-efficient convolution
Air filter "to" nuclear convolution efficiency air filter "(see chapters, each chapter of the 2008 edition);
--- Increased cylindrical nuclear Universities air filter classification (see 4.3);
--- Modify the contents of the "dimensions bias", according to the dimensions and tolerances of form and position tolerances sub-item description, and modify the inside
Capacity; increased cylindrical nuclear grade HEPA filter relevant requirements (see 62, 63, 2008 edition 5.1.2.);
--- Remove the frame material "partakers of nuclear grade separator HEPA filter frame, in line with the standard provisions", which was
Content as a separate section lists (see 648, 2008 edition of 5.2.1.1..);
--- Increased requirements for cylindrical nuclear grade HEPA filter frame material (see 6.4.1.3);
--- To increase the content of "fastener material" (see 6.4.2);
--- Modify the contents of the "separator material" (see 644, 2008 Edition 5.2.3.);
--- Modify the radiation resistant material requirements (see 645, 6461, 727, 2008 edition of 5.2.4.1,5.2.5,6.2.5...);
--- Increased neoprene sheet content (see 6.4.6);
--- Description modified filter, increasing the content of cylindrical nuclear grade HEPA filter cartridge (see 6.5 1, 2008 edition
5.3.1);
--- Modify the outline of the contents (see 652, 2008 edition of 5.3.2.);
--- Increased cylindrical nuclear grade HEPA filter gasket relevant content (see 6.5.3.2);
--- Added "partition plates," "safety net" of structural requirements (see 6.5.4, 6.5.5);
--- The "filtration rate", "repair" and "filter" merger (see 651, 2008 edition of 5.3.5,5.3.6.);
--- Remove the overpressure resistance to dry relevant requirements (see the 2008 edition of 5.4.3.1);
--- Increase in seismic terms after passing the test filter inspection (see 6.6.8);
--- Other increases filter performance requirements (see 6.6.9);
--- Test Method for increasing the visual inspection (see 7.1.1);
--- Increased parallelism measurement method (see 7.1.3);
--- Increased measurement cylindrical nuclear grade high efficiency air filter technology parameters (see 7.1.5);
--- Increased early resistance test, efficiency test method (see 7.2.1, 7.2.2);
--- Modify the overpressure resistance test mist entrained air volume (see 724, 2008 edition of 6.2.2.2..);
--- Modify the airflow temperature heat test, complement cylindrical nuclear grade HEPA filter requirements (see 7.2 .. 5, 2008 edition
6.2.3);
--- Modify the fire resistance test temperature (see 726, 2008 edition of 6.2.4.1..);
--- To increase the content of the seismic tests (see 7.2.8);
--- Modify the type test conditions (see 842, 2008 Edition 7.4.1.);
--- Revised Sampling Plan prototype number (see 843, 2008 Edition 7.4.2.);
--- Added "test project" to improve the content type test (see 8.4.4);
--- Modify the pasted logo requirements, an increase of signs of moderate size (see 91, 2008 version 8.1.);
--- Amended "Packaging, transport and storage" and revise its content (see Chapter 10, Chapter 9, 2008 edition);
--- Increased nuclear grade high efficiency air filter content (see Appendix A);
--- Increased nuclear grade HEPA filter other performance requirements (see Appendix B).
