Описание (английский):

This determination may be required for the calculation of the dry mass used in analytical methods. Applies only to products with a moisture content of not more than 10 %. The principle consists in drying a test portion at 105 ° centigrade in a thermostatic oven, then weighing. The moisture content is calculated from the loss of mass of the test portion. Cancels and replaces the first edition ISO 585:1982, of which it constitutes a minor revision.

Overview

SIST EN ISO 585:2000 specifies a standardized method for the determination of moisture content in unplasticized cellulose acetate plastics. This method is essential for accurately calculating the dry mass of cellulose acetate used in various analytical and quality control procedures. The test applies only to cellulose acetate products with moisture content not exceeding 10%. The testing principle involves drying a sample at 105 °C in a thermostatic oven and calculating moisture loss by weighing before and after drying.

This standard represents a minor revision of the original ISO 585:1982 and aligns with ISO 585:1990, ensuring consistency in international testing practices for cellulose acetate moisture measurement.

Key Topics

Material Scope: Unplasticized cellulose acetate plastics with ≤ 10% moisture content.

Testing Method:

Drying sample in a thermostatic oven at 105 °C ± 2 °C for 3 hours.
Use of a glass weighing bottle with ground-glass lid to hold the sample.
Cooling in a desiccator with anhydrous calcium chloride before weighing.

Weighing Precision: Balance accurate to 1 mg for initial and final weights.

Calculation of Moisture Content: Moisture percentage is derived from the mass loss of the test portion before and after drying.

Repeatability: Two determinations are performed; if moisture results differ by more than 0.1%, the test is repeated to ensure accuracy.

Safety Considerations: Users must establish appropriate health and safety practices when handling materials and equipment during testing.

Applications

Quality Control: Ensures consistent moisture content in cellulose acetate raw materials and products, critical for manufacturing and downstream processing.

Analytical Chemistry: Provides accurate dry mass quantification required for various analytical tests on cellulose acetate.

Material Specification Compliance: Validates moisture levels according to international standards to meet industry requirements.

Research and Development: Facilitates material characterization and optimization in product design involving unplasticized cellulose acetate.

Industrial Usage: Applicable in plastic manufacturing sectors, including films, sheets, and molded goods where moisture content affects physical properties and performance.
