Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 17603-1998 "photolytic plastic outdoor exposure test method", compared with GB/T 17603-1998, the main
The technical changes are as follows.
--- Modify the "scope" chapter of the relevant content (see Chapter 1,.1998 edition of Chapter 1);
--- Modify the "Normative references" chapter of the reference file, the relevant documents with our latest document instead (see Chapter 2,
1998 edition of Chapter 2);
--- "Sunlight" to "sun", "exposure" was revised to "exposure cycle";
--- Modify the term "save sample" to "store sample" and modify its definition (see 3.2,.1998 version 3.2);
--- "Meaning" revised as "principle", modified the "principle" chapter of the content (see Chapter 4,.1998 edition of Chapter 4), with "too
Yang ultraviolet radiation exposure cycle "instead of" solar radiation exposure period ";
--- Modify the "experimental device" chapter of the content (see Chapter 5,.1998 edition of Chapter 5);
--- Revised "Radiometer" as "Radiometer", deleted the use of total radiometers in the test device "Radiometer", "Narrowband" repair
Change to "narrowband" (see 5.3,.1998 version 5.3);
--- Modify "Forming and Preparation" to "Specimen Preparation" and delete the requirements for thickness dimensions in "Specimen Preparation" (see Chapter 6,
1998 edition of Chapter 6);
--- Modify the "test steps" chapter of the content, adding a detailed description of the requirements of the test steps (see Chapter 7,.1998
Version of Chapter 7);
--- Modify the "test report" chapter of the content (see Chapter 8,.1998 edition of Chapter 8).
