GB/T 44139.2-2024Requirements for sleeping bags - Part 2: Raw material properties (English PDF)

Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents" Drafting.

This document is Part 2 of GB/T 44139 Requirements for Sleeping Bags. GB/T 44139 has been published in the following parts.

--- Part 1: Thermal performance, quality and dimensional requirements for sleeping bags designed for use at extremely low temperatures above -20°C;

--- Part 2: Raw material properties.

Introduction

With the progress of society and the improvement of people's living standards, people's outdoor leisure activities have gradually increased, and sleeping bags have become a popular choice for camping activities.

As sleeping bags need to be used in special outdoor environments, the performance of the product and the performance of the raw materials are very important.

GB/T 44139 aims to provide a basis for the quality control of sleeping bag products and their raw materials, and is intended to consist of two parts.

--- Part 1: Thermal performance, quality and dimensional requirements for sleeping bags designed for use at extremely low temperatures above -20°C.

It provides test methods for thermal resistance and applicable temperature, and puts forward clear requirements for product quality and size.

--- Part 2: Raw material properties. The purpose is to put forward performance requirements and test methods for raw materials used in sleeping bags.

The formulation of this document provides a basis for the quality control of sleeping bag products, promotes product quality improvement, ensures the personal safety of consumers, and also it is a measure to respond to the national call for national fitness and improve the level of supporting services. It is of great significance to promote the healthy development of the industry and meet the needs of the market.

Very important significance.
