Preparation of steel substrates before application of paints and related products - Specifications for metallic blast-cleaning abrasives - Part 3: High-carbon cast-steel shot and grit (ISO 11124-3:2018)

This document specifies requirements for 14 grades of high-carbon cast-steel shot and 11 grades of high-carbon cast-steel grit, as supplied for blast-cleaning processes. Values are specified for hardness, density, defect/structural requirements and chemical composition.
The requirements specified in this document apply to abrasives supplied in the "new" condition only. They do not apply to abrasives either during or after use.
Test methods for metallic blast-cleaning abrasives are given in the various parts of ISO 11125.
High-carbon cast-steel shot and grit are used in both static and site blasting equipment. They are most often selected where a facility exists for the recovery and re-use of the abrasive.
NOTE 1    Information on commonly referenced national standards for metallic abrasives and their approximate relationship with ISO 11124 is given in Annex A.
NOTE 2    Although this document has been developed specifically to meet requirements for preparation of steelwork, the properties specified will generally be appropriate for use when preparing other material surfaces, or components, using blast-cleaning techniques. These techniques are described in ISO 8504‑2.

Priprava jeklenih podlag pred nanašanjem barv in sorodnih premazov - Specifikacije za kovinske granulate za peskanje - 3. del: Kroglice (shot) in sekanci (grit) iz visokoogljičnega litega jekla (ISO 11124-3:2018)

Ta dokument določa zahteve za 14 razredov kroglic iz visokoogljičnega litega jekla in 11 razredov sekancev iz visokoogljičnega litega jekla, dobavljenih za peskanje. Določene so vrednosti za trdoto, gostoto, zahteve glede poškodb/strukture in kemijsko sestavo.
Zahteve v tem dokumentu se uporabljajo samo za granulate, ki so dobavljeni »novi«. Ne uporabljajo se za granulate med njihovo uporabo ali po njej.
Preskusne metode za kovinske granulate za peskanje so podane v različnih delih standarda ISO 11125. Kroglice in sekanci iz visokoogljičnega litega jekla se uporabljajo tako v opremi za statično peskanje kot peskanje na mestu uporabe. Najpogosteje so izbrani, kjer obstaja možnost obnovitve in vnovične uporabe granulata.
OPOMBA 1: Informacije o pogosto sklicevanih nacionalnih standardih za kovinske granulate in njihovem približnem razmerju s standardom ISO 11124 so podane v dodatku A.
OPOMBA 2: Čeprav je bil ta dokument pripravljen posebej za izpolnjevanje zahtev za pripravo jekla, so opredeljene lastnosti na splošno ustrezne za uporabo pri obdelavi površin drugih materialov ali sestavnih delov s tehnikami peskanja. Te tehnike so opisane v standardu ISO 8504-2.

Overview

EN ISO 11124-3:2018 - Preparation of steel substrates before application of paints and related products - Part 3: High-carbon cast-steel shot and grit (ISO 11124-3:2018) specifies quality and supply requirements for metallic blast-cleaning abrasives produced from high‑carbon cast steel. The document defines 14 grades of high‑carbon cast‑steel shot and 11 grades of high‑carbon cast‑steel grit, with mandatory values for hardness, apparent density, defect/structural limits and chemical composition. Requirements apply to abrasives supplied in the new condition only and are intended for use in both static and site blasting equipment, typically where recovery and re‑use systems exist.

Key Topics and Requirements

• Abrasive grades and designation: Grade coding (e.g., M/HCS/S140 or M/HCS/G140/570‑710HV) identifies material type (metallic high‑carbon cast‑steel), shape (S = shot, G = grit) and nominal particle size.
• Material properties specified:
  • Hardness ranges (Vickers values) where alternatives exist
  • Apparent density (bulk density) requirements
  • Chemical composition limits (C, Si, Mn, P, S determined by referenced ISO methods)
  • Defect/structural requirements (voids, shrinkage, cracks, percentage defective particles)
• Sampling and testing: Sampling and test methods are referenced to the ISO 11125 series:
  • ISO 11125‑1 (sampling)
  • ISO 11125‑2 (particle size distribution)
  • ISO 11125‑3 (hardness)
  • ISO 11125‑4 (apparent density)
  • ISO 11125‑5 to ‑7 (defective particles, foreign matter, moisture)
• Traceability and marking: Package identification and lot traceability, plus required supplier information on orders.
• Scope limit: Applies only to abrasives in their new condition - not to material during or after use.

Applications and Users

Practical uses and typical users include:

• Surface preparation / blast cleaning of steelwork prior to painting or coating
• Specifiers and coating engineers selecting an abrasive for a required surface profile and cleaning performance
• Abrasive manufacturers and suppliers ensuring product conformity and correct labelling
• Blasting contractors and asset owners using shot/grit in static or mobile plants with recovery and re‑use systems
• Quality assurance and inspection teams performing acceptance testing and verification

EN ISO 11124-3:2018 helps ensure consistent abrasive performance for achieving targeted surface cleanliness, profile and coating adhesion.
