GB 4543-2008Pyrotechnic distress signals (English PDF)

Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents" Drafting:

This document replaces GB/T 4543-2008 "Ship Pyrotechnic Signals" and GB/T 3107-2008 "Self-illuminating floating lights and spontaneous smoke for lifebuoys" "Fog Combination Signal", compared with GB/T 4543-2008, in addition to structural adjustments and editorial changes, the main technical changes are as follows:

a) Changed classification and labeling examples (see 4.1, 4:2, 4:1, 4:2 of the:2008 version);

b) Added requirements and test methods for spontaneous smoke signal release of lifebuoys (see 5.2:3 and 6:4:2);

c) Changed the color requirements for rocket parachute flame signals and handheld flame signals (see 5.3:5, 5:4:3,:2008 version of 5:2:5:5, 5:2:6:3);

d) Change the smoke shielding rate to smoke concentration (see 5.5:3, 5:2:7:3 of the:2008 version);

e) Added temperature requirements in the basic performance parameter test of floating smoke signals (see 6.8:1);

f) The validity period in the change mark is the expiration date (see 8.1, 8:1 of the:2008 version):

3 Terms and definitions

The following terms and definitions apply to this document:

pyrotechnicssignalpyrotechnicssignal A general term that uses the flame or smoke emitted after a chemical mixture (such as gunpowder) is ignited as a communication signal for identification:

flame signalflaresignal the chemical mixture is ignited and burns flamingly and emits light and flame signals:

Note: Usually used as a night contact signal:

smoke signal when the chemical mixture is ignited, it burns flamelessly and emits a smoke signal:

Note: Usually used as a daytime contact signal:

When used, the smoke signal can be generated by itself only with the help of the automatic release device:

4 Classification and tagging

4.1 Classification

Pyrotechnic signals are divided into the following four categories according to how they are used:

a) RF type---rocket parachute flame signal;

b) HF type---handheld flame signal;

c) BS type---floating smoke signal;

d) LS type---lifebuoy spontaneous smoke signal:

4.2 Marking

The marking of the pyrotechnic signal consists of the document number, usage model, burning duration, and light intensity sequence:
