1 Scope
This part specifies the product classification, requirements, test methods, inspection rules, marking, packaging, transportation and storage of color masterbatch used for optical fiber loose tube (hereinafter referred to as "color masterbatch").
This part is applicable to the color masterbatch used for the coloring of optical fiber loose tube. The color masterbatch is made by processing with polybutylene terephthalate (PBT), polypropylene (PP) or polycarbonate (PC) as the application object, adding an appropriate amount of pigment, dye, dispersant and other processing additives.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 15608 and the following apply.
3.1
munsell color system
color classification and calibration system developed by Albert H. Munsell according to the visual properties of colors. It uses a model similar to a sphere to express all the three basic properties of various surface colors: hue, lightness and intensity. Each part of the three-dimensional model represents a specific color and has a label corresponding to it.
3.2
dilution ratio
matching ratio of color masterbatch and base material provided by the manufacturer in order to meet the requirements of normal color system, that is, the diluble multiple
