Introduction

Despite the continuous upgrading of ship safety equipment and technology, many maritime safety accidents have occurred in recent years. Inflatable liferaft as a ship

As an important product of life-saving equipment, it is used to ensure the safety of personnel on board, and it is necessary to stipulate its design, performance and test.

GB/T 34315 consists of three parts.

--- Part 1.Type I. Requirements for design, performance, and test methods are put forward for Type I liferafts with a wider range of use, aiming to ensure the

The quality of the type life raft to protect the safety of the people on the raft.

--- Part 2.Type II. The requirements for design, performance, and test methods of type II liferafts are proposed to ensure the quality of liferafts of this type.

to protect the safety of the people on the raft. The conditions for the application of Type I liferafts are different.

--- Part 3.Materials. Requirements and test methods for materials used in the construction of Type I and Type II liferafts for the purpose of ensuring life-saving

properties of raft materials.

Life rafts complying with this document can provide reasonable safety shelter for persons awaiting rescue and have a reasonable service life (as long as

The user meets the storage and maintenance recommendations expressly specified by the manufacturer).

The experiments in this document are intended to simulate reality as closely as possible. Compliance with a test does not guarantee similar performance in use. example

For example, compliance with the re-righting test does not guarantee that the liferaft will in all circumstances be righted at sea by an exhausted person.
