GB 16930.1-2014Tactile sticks-Part 1: A sign of safety color (English PDF)

Foreword

Part 4 of this Chapter are mandatory, others are recommended. GB 16930 "cane" is divided into two parts.

--- GB 16930.1 cane - Part 1. safety colors;

--- GB/T 16930.2 cane technical conditions. This is Part 1 GB 16930's. This section drafted in accordance with GB/T 1.1-2009 given rules. This Part replaces GB 16930.1-1997 "blind cane safety colors", compared with GB 16930.1-1997 major technical change Of the following.

--- Modifications and additions some of the terms and definitions (see Chapter 3, Chapter 3, 1997);

--- Modified cane safety color marking requirements (see 41, 1997 Version 4.1.);

--- Modify the deaf-blind cane safety color marking requirements (see 42, 1997 Version 4.2.);

--- Increased performance and color photometric performance requirements (see 4.3, 4.4);

--- Increasing the detection method (see Chapter 5). This section proposed by the People's Republic of China Ministry of Civil Affairs. This part of the National Rehabilitation and special equipment Standardization Technical Committee on Persons with Disabilities (SAC/TC148) centralized. This section drafted by: National Rehabilitation Device Quality Supervision and Inspection Center, China Association of the Blind, the National Traffic Safety Facilities Quality Supervision and Inspection Inspection center, Dominion Optical Co., Ltd., Beijing school for the blind, physically handicapped rehabilitation center in Sichuan, Guangdong, Yang Kai Medical Technology Group has Ltd., Shanghai Medical Devices Co., Ltd. each state. The main drafters of this section. in Juan-juan, Gu Yaling, Li Weihong, Su Wenying, Wang, Wang Qi, Wang Lili, Li Minghui, Huangfei Qing Yi-Ming Zhao, Zhang, Wang Wei, Li Jinfeng. This part of the standard replaces the previous editions are.

--- GB 16930.1-1997. The cane Part 1. safety colors

1 Scope

Part 1 of China's mandatory national standard for tactile sticks, covering the safety colour marking. A tactile stick is a blind person's white cane, and the standard's subject is the property that protects them from traffic rather than from obstacles: the cane is white with red bands, and that combination is a legally recognised signal to drivers everywhere that the person carrying it cannot see them. It works only if it is unmistakable, which is why the colours are specified colorimetrically rather than by name and why the retro-reflective performance matters - the cane is most needed at night, when a driver sees only what the headlamps return. This part specifies the colours, their arrangement along the cane and the reflective requirements, and it is what makes a Chinese white cane read the same to a driver as one carried anywhere else.

This section provides security cane color logo terms and definitions, requirements and test methods related. This section applies to cane safe color logo design, production, use and related fields.

3 Terms and Definitions

GB 2893, GB/T 16930.2 and JT/T 688 as defined in the following terms and definitions apply to this document.

3.1 Cane tactilesticks White stick whitecanes Guide for the visually impaired or the appliance identification surroundings.

3.2 Blind and deaf stick deaf-blindsticks Both visually impaired hearing impaired guide for an appliance or identify the surrounding environment, a special form of cane.

3.3 Safety colors safetycolor Information transfer security implications of colors, including red, blue, yellow, green, four colors.

3.4 Contrasting colors contrastcolor Make security more visible color contrasting colors, including black and white colors.

3.5 Retroreflective retroreflection Reflected light returned from the opposite direction near the reflection of incident light. When the direction of the incident light changes in a wide range, can still guarantee Hold of this nature.

3.6 Reflective film retroreflectivesheeting One kind of film has been made of retroreflective material can be directly applied.

3.7 Coefficient of luminous intensity coefficientofluminousintensity RI Illumination E of retroreflective observation direction of the luminous intensity and I fall toward the retroreflective body and the direction perpendicular to the plane of incidence Ratio, namely. RI = I/E (1) Where. RI

--- coefficient of luminous intensity, in units of candela per lux (cd · lx-1); I

--- luminous intensity unit candela (cd); E

--- vertical illuminance, the unit is lux (lx).

3.8 Coefficient of retroreflection coefficientofretroreflection RA Than retroreflective surface coefficient of luminous intensity RI and retroreflective body surface area A, namely. RA = RI/A = I/(E × A) (2) Where.

--- Coefficient of retroreflection the RA, in units of candela per lux square meter (cd · lx-1 · m-2); RI

--- coefficient of luminous intensity, in units of candela per lux (cd · lx-1); A
