Описание (английский):

This document specifies a method for estimating the flow properties of a mixture of coating powder and air. The results obtained are influenced by the composition of the coating powder, its density, particle size distribution and particle shape, together with the tendency of the particles to agglomerate and to accept a charge.

Overview

EN ISO 8130-5:2021 specifies a standardized method for determining the flow properties of a powder/air mixture, particularly for coating powders. This European and International Standard is essential for industries utilizing powder coatings, ensuring the consistent quality of application processes by characterizing how powders behave when fluidized with air. The method assesses flow properties influenced by powder composition, density, particle size and shape, agglomeration tendency, and electrostatic charge acceptance.

Key Topics

Scope of Testing: Defines a laboratory procedure to estimate transport and spraying characteristics of coating powders as they interact with air.

Influencing Factors: Highlights critical powder properties - such as density, particle size distribution, and shape - that affect fluidization and flow rate.

Testing Conditions: Specifies standard conditions for temperature, humidity, and air pressure to ensure reproducibility and comparability of results.

Measurement Parameters:

Fluidization factor (φ): Calculated from the height of the powder at rest and during fluidization.
Powder flow rate (R): Calculated using the mass of powder discharged and the fluidization factor during a set time interval.

Apparatus Requirements: Outlines necessary equipment, including a fluidization vessel, dry air source, flowmeter, analytical balance, and associated sampling and measuring tools.

Result Validation: Emphasizes the use of repeated measurements and averaging to ensure reliable and representative flow property data.

Applications

EN ISO 8130-5:2021 delivers tangible value across industries that use coating powders, particularly in:

Powder Coating Manufacturing: Quality control for batch consistency, ensuring powders are suited for automated spray or fluidized bed applications.

Industrial Surface Finishing: Evaluation of powders before application to metals, automotive parts, furniture, electronics, and appliances for uniform coat thickness and appearance.

Product Development: Assists in R&D efforts to optimize powder formulations for improved application characteristics.

Process Calibration: Helps equipment manufacturers and operators set optimal parameters for powder feed, air flow, and electrostatic charging in coating processes.

Regulatory Compliance: Enables manufacturers and suppliers to meet international and European powder coating standards, facilitating market access and customer confidence.

Related Standards

For comprehensive powder coating quality assurance, consider these closely associated standards:

EN ISO 8130-14: Coating powders - Vocabulary. Provides terminology relevant to powder coatings, supporting harmonized communication.

ISO 15528: Paints, varnishes, and raw materials - Sampling. Details procedures for representing powder samples in testing.

Other EN ISO 8130 Series Parts: Address additional powder coating test methods, such as particle size analysis, electrostatic chargeability, and melt flow index.

Practical Value

By following EN ISO 8130-5:2021, organizations can:

Achieve consistent coating performance by selecting powders with validated flow properties

Reduce application defects and material waste in production

Enhance the efficiency of powder coating process setup and troubleshooting

Provide transparent and standardized product data to customers, auditors, and regulators

EN ISO 8130-5:2021 is a key reference for professionals in paint, coating, and surface finishing industries aiming for process optimization and international standardization in powder coating operations.
