CEN/TC 202/WG 4 - Blasting

This standard specifies requirements to be met by the manufacturer of abrasive blasting equipment for the foreseeable significant hazards due to design, construction and installation, during commissioning, operation, maintenance and decommissioning of the equipment which employ either centrifugal force or compressed air as a means of accelerating abrasive to achieve the desired result.
Abrasive blasting equipment covers:
-   centrifugal blasting machines;
-   air blasting machines;
-   loading, conveying and unloading systems for the workpieces.
See Annex A for more details.
This standard covers all foreseeable significant hazards which could be encountered during the lifetime of the machine as listed in clause 5.
This standard does not apply to:
-   mobile centrifugal blasting equipment;
-   mobile air blasting equipment;
-   wet blasting equipment;
-   the general works compressed air supply system.

This document specifies safety and environmental requirements for shot blasting machinery.
Shot blasting machinery includes:
—     wheel blasting machinery;
—     air blasting machinery for dry and wet blasting;
—     combined wheel and air blasting machinery.
NOTE            Annex A illustrates examples of shot blasting machinery.
This document is applicable to:
—     all significant hazards, hazardous situations and hazardous events relevant to shot blasting machinery, when used as intended and under the conditions foreseen by the manufacturer, including reasonably foreseeable misuse;
—     measures for minimization of environmental impact and energy usage of shot blasting machinery.
Interfaces between shot blasting machinery and other equipment used in shot blasting but not in the scope of this document are:
—     mechanical and electrical interface to external workpiece transport system;
—     connector to electrical energy supply;
—     connector to fresh air supply ducting;
—     connector to exhaust air ducting;
—     connector to pressurized air supply;
—     connector to water supply;
—     connector to waste water system;
—     interface for safe exchange of control signals;
—     connector for fresh air supply for respiratory protection device (in blast rooms).
NOTE            Annex C gives an illustration of interfaces between shot blasting machinery and other equipment used in shot blasting but not in the scope of this document.
The specific significant risks related to mobile and movable shot blasting machinery (e.g. shot blasting machines designed for operation at changing locations) are not dealt with in this document.
This document does not apply to:
—     high pressure water jet machinery;
—     dry-ice blasting machinery.
This document does not apply to shot blasting machines manufactured before the date of its publication as an ISO standard.
NOTE            The requirements specified in this document can serve as a guideline for a risk assessment of shot blasting machines manufactured before the date of its publication as an ISO standard.
