ISO 8117:2003

Overview

ISO 8117:2003 is an international standard developed by the International Organization for Standardization (ISO) that specifies the nominal diameters and numerical designations of circular knitting machines. This standard applies to both small- and large-diameter circular knitting machines, including sinker machines. It provides a clear classification and dimensioning system essential for manufacturers, engineers, and users in the textile machinery industry.

The standard helps ensure consistency and interoperability across different machine manufacturers by establishing uniform measurement criteria for circular knitting machines, a key component in the fabric manufacturing process.

Key Topics

• Nominal Diameters: ISO 8117:2003 defines nominal diameters in millimeters for circular knitting machines, covering a broad range from small to large machines.
• Numerical Designations: It maps each nominal diameter to a specific numerical designation that corresponds to the size of the machine.
• Applicability: The standard is relevant to all types of circular knitting machines, including sinker machines, which are widely used in textile manufacturing.
• Reference to Related Standards: The standard cross-references ISO 7839 for classification and vocabulary of knitting machines and ISO 8188 for needle pitches, integrating a comprehensive framework for knitting machine specifications.
• Avoidance of Specific Sizes: ISO suggests avoiding certain machine diameters indicated in brackets to facilitate better industry standardization.

Applications

ISO 8117:2003 facilitates several practical uses within the textile and machinery manufacturing sectors:

• Machine Design and Development: Engineers use the nominal diameter classifications to design and build circular knitting machines that conform to global standards.
• Purchase and Supply Chain: Buyers and suppliers can reliably specify and identify machine sizes, ensuring compatibility and efficient procurement.
• Maintenance and Repair: Standardized measurements allow for accurate parts replacement and maintenance scheduling for circular knitting machines.
• Quality Control: Manufacturers and industry inspectors apply the standard to verify machine sizes during quality assurance processes.
• International Trade: Helps streamline export and import documentation by providing universally accepted specifications.

Related Standards

ISO 8117:2003 is part of a wider suite of ISO standards concerning textile machinery:

• ISO 7839 – Textile machinery and accessories: Provides classification and vocabulary for knitting machines, supporting clear communication across the industry.
• ISO 8188 – Textile machinery and accessories: Establishes the pitch of knitting machine needles, essential for understanding machine knitting capabilities.
• ISO/TC 72 – The technical committee responsible for textile machinery, offering ongoing updates and new standards related to textile manufacturing equipment.

By adhering to ISO 8117:2003, manufacturers and users of circular knitting machines benefit from enhanced clarity, interchangeability, and global recognition that optimize production efficiency and quality in the textile industry. Keywords such as "circular knitting machines," "nominal diameters," "textile machinery standards," and "knitting machine sizes" are vital for professionals seeking reliable and standardized information in this sector.
