Foreword

This Standard was drafted as per the rules specified in GB/T 1.1-2009.

This Standard replaced GB/T 5714-1997 Textiles - Tests for Color Fastness - Color

Fastness to Sea Water. Compared with GB/T 5714-1997, this Standard has the major

changes as follows:

--- Add "this Standard is applicable to various kinds of textiles" to the scope (see

Clause 1 of this Edition);

--- Add the references of GB/T 6682, GB/T 13765, GB/T 32598 and GB/T 32616;

separately modify GB 250-1995, GB 251-1995 and GB/T 6151-1997 into GB/T

250, GB/T 251 and GB/T 6151-2016; adjust GB 7564~7568-1987 into GB/T

7568.1~GB/T 7568.6; adjust GB 11404-1989 into GB/T 7568.7 (see Clause 2 of

this Edition; Clause 2 of 1997 Edition);

--- Add the description of using instruments to assess the discoloration of the

sample and the staining of the lining fabric (see Clause 3 of this Edition);

--- Modify the title of Clause 4 from "equipment and reagents" into "equipment and

materials" (see Clause 4 of this Edition; Clause 4 of 1997 Edition);

--- Add tolerances to the specimen dimension and the pressure of the specimen

device; adjust "other devices with equivalent test results can also be used" from

the NOTE to the text (see 4.1 of this Edition; 4.1 of 1997 Edition);

--- Adjust "GB/T 6151-1997, 8.1" into "GB/T 6682"; add the requirements of "taking

sodium chloride as chemically pure or above"; add the NOTE of "sodium chloride

solution shall be prepared for current use" (see 4.3 of this Edition; 4.3 of 1997

Edition);

--- Add the NOTE of "other types of fibers can be used with reference to the same

or similar fibers" (see 4.4.2 of this Edition);

--- Delete the standard lining fabric of acetate or triacetate fiber (see Table 1 of this

Edition; Table 1 of 1997 Edition);

--- Adjust the contents of 4.5 into 4.5 and 4.6 (see 4.5 and 4.6 of this Edition; 4.5 of

1997 Edition);

--- Add 4.7, 4.8, 4.9 and 4.10 (see 4.7, 4.8, 4.9 and 4.10 of this Edition);

--- Add the tolerance of specimen dimension (See Clause 5 of this Edition);

---Add the requirements of "bath ratio of about 50:1" and "stand at the room

3 Principle

Use a piece of textile specimen to make combined specimen with two pieces of single

fiber lining fabrics and one pieces of multi-fiber lining fabric; dip it into the sodium

chloride solution; extrude excessive solution and place it in middle of the two plates of

the test device; so that it can withstand the specified pressure. The specimen and lining

fabric shall be dried separately. Use the grey scale or instrument to assess the

discoloration of the specimen and staining of the lining fabric.
