Foreword

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

This standard replaces JG/T 255-2009 "Built-in sunshade hollow glass products", compared with JG/T 255-2009, the main technical changes as follows.

---The structural classification of the built-in sunshade has increased the combination curtain (see 4.1.2);

---The operation mode of the built-in sunshade device has been fixed (see 4.1.3);

---Modified the marking method (see 4.2, 4.2 of the 2009 edition);

---Modified the material requirements for shading devices (see 5.1.2, 5.1.3 of the 2009 edition);

---Modified the requirements of equalizing pipe (see 5.1.3, 6.1.5, 5.1.2 of the 2009 edition);

---Added requirements for fire integrity and vacuum glass (see 5.1.1, 6.1.1, 6.1.2);

---The appearance quality and operating force requirements have been revised (see 6.2, 6.5, 6.1, 6.4 of the 2009 edition);

---Modified the dew point requirements (see 6.7, 6.6 in the 2009 edition);

---Accelerated durability test is modified into water and gas seal durability performance and gas seal durability performance (see 6.9, 6.11, 2009 edition 6.8);

---Increase the initial gas content requirements (see 6.10);

---The shading coefficient is changed to the solar heat gain coefficient (see 6.13, 6.9.2 in the 2009 edition);

---The daylighting performance is modified to visible light transmittance (see 6.14, 6.10 in the 2009 edition);

---Modified the sample specifications (see 7.1, 7.1 of the 2009 edition);

---Revised the corresponding test method (see Chapter 7, Chapter 7 of the 2009 edition).
