BS 2782-7:Method 732D:1999, ISO 1628-4:1999

Overview

BS 2782-7: Method 732D:1999, in conjunction with ISO 1628-4:1999, provides a comprehensive methodology for assessing the rheological properties of polycarbonate (PC) moulding and extrusion materials. This standard specifically outlines the procedure for determining the viscosity of these materials in dilute solution using capillary viscometers. Understanding the viscosity of polycarbonate is crucial for manufacturers and processors in the rubber and plastics industries, as it directly impacts processing conditions and product performance.

Key Requirements

The standard delineates specific requirements for conducting viscosity measurements, which include:

• Sample Preparation: Guidelines for preparing dilute solutions of polycarbonate to ensure accurate viscosity readings.
• Equipment Specifications: Detailed descriptions of the capillary viscometers to be used, including calibration and maintenance protocols.
• Measurement Conditions: Standardised conditions under which viscosity measurements must be performed, including temperature control and flow rate considerations.
• Data Reporting: Requirements for documenting and reporting the viscosity results, ensuring consistency and traceability.

Implementation Benefits

Adopting BS 2782-7: Method 732D:1999 offers several benefits for organisations involved in the production and processing of polycarbonate materials:

• Enhanced Quality Control: Regular viscosity testing allows for the early detection of material inconsistencies, leading to improved product quality.
• Optimised Processing Conditions: Understanding the viscosity of materials helps in adjusting processing parameters, thereby enhancing efficiency and reducing waste.
• Informed Material Selection: Accurate viscosity data aids in selecting the appropriate materials for specific applications, ensuring compatibility and performance.

Compliance Value

Compliance with BS 2782-7: Method 732D:1999 and ISO 1628-4:1999 is essential for organisations aiming to meet industry standards and regulatory requirements. By adhering to these standards, companies can:
