Описание (английский):

This document specifies a method for the calculation of the lower explosion limit of a coating powder, i.e. the minimum concentration of the coating powder in air which will form an explosive mixture. It is based on the measurement of the gross calorific value of the product, as determined by the method described in ISO 1928.

Abstract

Overview

Key Topics

Scope and Purpose Specifies calculating the LEL specifically for powder coatings by analyzing their energy content and behavior in air.
Principle of Measurement The LEL calculation is based on the gross calorific value-essentially the heat of combustion of 1 gram of powder. This energy measurement is used to predict explosivity.
Calculation Method Utilizes a formula incorporating constants and the gross calorific value to derive the LEL in grams per cubic meter (g/m³).
Sampling and Testing Requires representative sampling according to ISO 15528 and calorific value testing as per ISO 1928. Calculation can be direct from measured values or estimated by summing values of the powder's combustible constituents.
Reporting Requirements Test reports must detail product identification, test methods, calculated or estimated results, deviations, anomalies, and test date.
Terminology Defines LEL as the minimum explosive concentration of coating powder in air, expressed in g/m³.

Applications

Powder Coating Manufacturing Producers use the standard to determine safe handling and storage limits, minimizing risks of powder explosions.
Safety Risk Assessments Industrial safety specialists apply this standard to evaluate explosion hazards in coating application plants.
Process Design and Compliance Engineers employ LEL calculations to design ventilation, dust extraction, and explosion protection systems compliant with safety regulations.
Quality Control Ensures consistent product safety and performance by monitoring the explosive potential of coating powders batch-to-batch.
Regulatory Compliance Facilitates adherence to international safety laws and standards for combustible dust handling, supporting workplace safety and environmental protection.

Practical Value

Enables safer handling and processing of potentially explosive coating powders.
Provides a simplified and accessible method compared to complex explosion testing apparatus.
Helps manufacturers and users avoid underestimation of explosion risks in powder coatings, even for powders with low flammability.
Supports the implementation of preventive measures such as fire suppression and explosion venting in relevant industrial settings.
