Foreword

The full technical content of this standard is mandatory.

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

This standard replaces GA 666-2006 "reflective film for motor vehicle number plates". Compared with GA 666-2006, except for editorial changes the technical changes are as follows.

--- Revised the "scope" (see Chapter 1, Chapter 1 of the 2006 edition);

--- Increased the term and definition of "tensile strain" (see 3.1);

--- Increased the term and definition of "tensile strength" (see 3.2);

---Modified "Classification and Model" (see Chapter 4, Version 4.1 of 2006);

--- Revised the requirements of the "volume requirements" (see 5.1, 2006 version 4.2.3);

--- Revised the requirements of the "reflective surface" (see 5.2.1, 4.2.1 of the 2006 edition);

---Modified the requirements of "anti-stick paper" (see 5.2.2, 4.2.2 of 2006 edition);

---Modified the requirements of the "identification" (see 5.3, 4.2.4 of the 2006 edition);

--- Modified the requirements of "retroreflection performance" (see 5.4, 4.3 of 2006 edition);

--- Revised the "surface color" requirements (see 5.5.1, 2006 version 4.4.2);

--- Modified the requirements of "retroreflective color" (see 5.5.2, 4.4.1 of the 2006 edition);

---Modified the requirements of "stretching performance" (see 5.6, 2006 edition 4.6.2);

--- Added the requirement of "release properties of release paper" (see 5.8);

--- Revised the requirements of "water resistance" (see 5.9, 2006 edition 4.10);

--- Increased the requirements of "production process adaptability" (see 5.18);

--- Revised the "test method" (see Chapter 6, Chapter 5 of the 2006 edition);

---Modified the "inspection rules" (see Chapter 7, Chapter 6 of the 2006 edition);

---Modified "packaging, marking and storage" (see Chapter 8, Chapter 7 of the 2006 edition);

--- Added "transition period requirements for standard implementation" (see Chapter 9).

3 Terms and definitions

The following terms and definitions as defined in GB/T 18833 apply to this document.

Tensile strain the increment of the original gauge length unit length, expressed as a dimensionless ratio or percentage (%).

[GB/T 1040.1-2006, definition 4.4] 3.2 Tensile strength the maximum tensile stress experienced by the specimen during the tensile test.

Note. The unit is Newton (N).
