The standard proposed by China National Light Industry Council.

This standard by the China Sewing Machinery Standardization Technical Committee (SAC/TC152) centralized.

This standard was drafted. SGSB (Group) Co., Ltd., Shanghai Institute of sewing machines, large-ho Beijing Science and Technology Company Limited Secretary, National Sewing Machine Quality Supervision and Inspection Center, Zhejiang gem Electromechanical Co., Ltd., Xi'an Standard Industrial Co., Ltd., in the Czech Republic Sewing Machine Co., Ltd. Zhejiang new leap.

Introduction

From a technical point of this standard is to provide industrial manufacturers, users and official bodies with sewing machines, sewing units and sewing systems should meet Safety requirements.

For dangerous machines and not within the scope of this standard, see ISO 12100-1 and ISO 12100-2.

The standard in dealing with major hazard (see Chapter 4) and safety requirements (see Chapter 5) and then when you have taken the first detailed overview of ways; first introduced for all types of industrial safety requirements for sewing machines, and then lists the special requirements of special models.

Industrial sewing machines is a major feature of the sewing units and sewing systems often be assembled by the user with different manufacturers and parts Into, and during use, or add users to swap parts leaving the sewing unit and auxiliary equipment systems to adapt to different processing requirements (For example, changing fashion), such measures can also be used to improve the degree of automation of the machine. As a result, several components assembled into a new seam Sewing unit or system users will be in a position manufacturers, like manufacturers should also have a responsibility to ensure the elimination of the risk attendant risks, Machinery and compliance with this standard and other relevant standards or regulations.

Industrial Sewing Machines Safety requirements for sewing machines, sewing units and sewing systems

1 Scope

This standard applies to include apparel and footwear, leather goods, shirts, socks and hosiery, underwear, gloves, interior decoration and packaging industry, Shoe repair and other sectors (industrial, commercial or test) designed for professional use sewing machines, sewing units and sewing systems, such as the present standard sewing Machines, sewing units and sewing systems identified hazard exists, the provisions of the relevant safety requirements.

This standard does not consider the use of such machines and the danger that might arise during maintenance in other industries.

The standard safety requirements applicable to the processing machine sewing material dried in a dry, well-managed, clean environment. Of not drying tube Well-managed, sewing machines, sewing units and sewing systems used in clean environment, there should be more stringent security measures. for example, installed enclosure to mention High degree of protection (IP Code --- see GB 4208) [2].

This standard is intended to help manufacturers in the design of the machine when you consider reducing or eliminating the use and maintenance of this standard as hazardous risk. 4.2 to 4.8 lists the major hazards and dangerous situations corresponding safety requirements and measures. Significant risk are those that have been identified and Hazard assessment for the need to take measures to reduce the risks.

This standard does not apply to the stepping movement body type sewing machines, sewing machines and shoe soles in line with ISO 11111 [23] large Schiffli embroidery machine belongs Integrated sewing system or in compliance with GB 4706.74 [3] household sewing machines within GB 16655 [6] range.

Note. When the household sewing machine for professional use, it is necessary to take measures in accordance with this standard (for example, using the finger guards).
