What is BS EN ISO 11124-2:2013?

BS EN ISO 11124-2:2013 is a technical standard that provides guidelines and specifications for the preparation and execution of steel grit and steel shot abrasives. It focuses on their use in blast-cleaning operations for metallic surfaces in various industries.

Understanding the Scope

The scope of BS EN ISO 11124-2:2013 encompasses the classification, sampling, and testing of steel grit and steel shot abrasives. It also includes the requirements for their conformity assessment and marking. This standard applies to new abrasives for both manual and machine blasting operations. It does not cover recirculation or rescreening processes.

Key Parameters and Performance Tests

BS EN ISO 11124-2:2013 sets out specific parameters that must be considered when using steel grit and steel shot abrasives. These include size, hardness, and chemical composition. For instance, when it comes to size, the standard provides different ranges (G10 to G120) to suit diverse applications.

Performance tests are also specified by this standard to evaluate the effectiveness of the abrasives. Some of the performance criteria involve determining particle shape, microstructure, and fatigue life. These tests ensure that the abrasives meet the necessary quality standards and can deliver the desired surface preparation and finish.

Importance of Compliance

Compliance with BS EN ISO 11124-2:2013 is crucial to ensure the efficiency and safety of blast-cleaning operations. By adhering to the guidelines outlined in this standard, businesses can achieve consistent and high-quality results. Proper classification, testing, and conformity assessment help professionals choose the appropriate steel grit or steel shot abrasives for their applications.

Moreover, compliance with this standard also promotes environmental protection. It ensures that the abrasives are free from contaminants and hazardous substances, reducing the risk of pollution during blast-cleaning processes.
