Different Flame Retardant rating of USB Charger data cable

Author:Sinodec Industrial Co., Ltd. Click: Time:2022-03-21 16:34:46

As we all know, the flame retardant rating of USB Charger data cable is different. Founded in 2003, Sinodec Industrial Co.,Ltd. is a professional manufacturer and exporter of TWS wireless bluetooth earphone headset, USB cables, USB hub and USB charger adapter.


How are HB, V-2, V-1 and V-0 defined?  The flame retardant grade of plastics increases gradually from HB, V2, V1 to VO

HB: The lowest flame retardant grade in UL94 and CSA C22.2 No 0.17 standards.  It is required that the burning speed is less than 40mm/min for the samples of 3~13mm; the burning speed is less than 70mm/min for the samples of less than 3mm; or it should be extinguished before the 100mm mark;


V-2: After two 10-second burning tests on the sample, the flame goes out within 60 seconds.  There may be burning objects falling;


V-1: After two 10-second burning tests are performed on the sample, the flame goes out within 60 seconds.  No burning objects should fall;


V-0: After the sample is subjected to two 10-second burning tests, the flame is extinguished within 30 seconds.  No burning objects should fall;

Color definition of wire

Basic knowledge of wire

Main color of electronic wire:

Black, brown, red, orange, yellow, green, blue, purple, gray, white, pink, light blue, light gray.  Communication cable pair main-auxiliary color

a) Line (main color): white, red, black, yellow, purple

b) Line (auxiliary color): blue, orange, green, brown, gray multi-logarithm based on the main and auxiliary colors:



With / insulation color / color bar / color dot / color circle / core line marking and other methods for identification.  Or make it into a basic unit, with cable ties for identification;


Other wire colors:

Mainly in accordance with the requirements of wire standards or association standards (such as ICEA Insulated Cable Engineer Association, and Western European electronic standards WesternElectric, etc.).

North American AWG system: Black (L) White (N) Green (E) Red (4) Yellow (5) Orange (6)

European Harmonized System: Brown (L) Blue (N) Yellow/Green (E)


Or except the ground wire is yellow/green wire, all are black, and each wire is printed with 1, 2, 3, 4, etc. or the color standard developed by the company for the convenience of unified management.

Specific color standards refer to PANTONE, or RAL 840 HR and RAL841 GL.

Or the customer's actual sample color (see attachment 02 PANTONE color card, 03 RAL_German standard).  The outer quilt (sheath) has no regulations and can be made according to user requirements


The provisions of IEC 757 on color codes and abbreviations:

Introduction to the classification of wire


Classified by material (refer to UL758): For example, UL (Underwrite’s Laboratories) American Commercial Insurance Laboratory, American National Standard ANSI adopts 70% UL standard as its standard:

Basic knowledge of wire (cable white paper)

Classified according to safety standards:


CCC standard: China Electrical Equipment Certification Committee standard 3C logo as shown on the right, the wires we often use mainly include: BVR, RVV, RV, RVB, etc.;

UL standard: The standard of the American Commercial Insurance Laboratory, the logo is shown on the right. The wires we often use are mainly: UL1007, UL1015, UL1061, UL3266, UL3271, UL1330, SJTW#12*2C, UL2651, UL20276, UL2464, etc.


Basic knowledge of wire (cable white paper)

Classified by shape:


Round wire: such as UL1015, UL1007, SJTW#12/3C, SVT#18/2C, RVV3*1.5, etc.

Flat wire: such as FFC, UL2651, UL2468, SPT-3, RVVB, etc., see the following table:

The meaning of wire printing


The printed content should include: certification mark, certification code, wire gauge, wire number, pressure rating, heat resistance rating, fire rating, etc.  Click to view: Training course materials on wire surface printing


Description of UL printing content:


AWM: American wire gauge;


1015: Model;


VW-1: UL vertical resistance 105℃: rated temperature;


E****: UL certification number;


AWG18: wire number;


CARVE: supplier;


600V: rated voltage;


CSA LL****: Canadian certification number


TEW 105: Canadian model;


FT1: CSA vertical flame retardant.


(AWM: appliancewiring material; AWG: American Wire Gauge; CSA: Canadian Standards Association)


There are also some words such as I/II and A/B that mean the following: Class I internal use, Class II external use


Group A is not subject to mechanical abrasion, Group B is subject to mechanical abrasion, W is used in a wet environment, O oil-proof, F-proof fuel oil, etc., FT1 vertical burning test, FT2 horizontal burning test, FT4 vertical burning test, FT6 horizontal burning and smoke  test.
