Introduction

GB/T 25115 "Safety Requirements for Industrial Washing Machinery" is proposed to consist of six parts.

---Part 1: General Requirements. The purpose is to identify the hazards of industrial washing machinery and establish general safety requirements.

---Part 2: Washing Machines and Washer-Extractors. The purpose is to determine specific safety requirements for products such as washing machines and washer-extractors.

---Part 3: Tunnel Washing Machines and Related Machinery. The purpose is to identify tunnel washing machines and related machinery.

Specific security requirements.

---Part 4: Dryers. The purpose is to determine the specific requirements for dryer products.

---Part 5: Ironing Machines, Feeders, and Folding Machines. The purpose is to determine the specific safety features of products such as ironing machines, feeders, and folding machines.

All requirements.

---Part 6: Ironing and Bonding Machines. The purpose is to determine specific safety requirements for products such as ironing and bonding machines.

ISO 10472 (all parts) is structured into several parts, consisting of general requirements and related equipment-specific requirements. Part 1 is...

The general requirements are listed above, while the other sections are product-specific requirements. For products covered by the specific requirements, their safety requirements are the general requirements combined with the specific requirements.

The requirements are to be used in combination, including supplements and modifications to the corresponding clauses in the general requirements within specific requirements, in order to provide a complete description for each product.
