Escopo e aplicabilidade

This standard applies to various types of shot (air) blast equipment used for surface treatment of workpieces, including shot blasting, air blasting, and combined processing. It is mandatory for designers, manufacturers, suppliers, and users of these machines. The standard also covers individual units and auxiliary equipment that constitute the blast equipment. It references essential safety standards like GB/T 15706.1 and GB 20905.

Requisitos técnicos

The standard specifies comprehensive mechanical safety requirements to mitigate risks such as abrasive projection, crushing, and shearing. Equipment doors must be interlocked with the blasting controls to prevent operation when open. Observation windows must use shatterproof transparent panels, and internal walls must be lined with wear-resistant protective plates. For control systems, the standard mandates sequential interlocking, automatic monitoring, and the inclusion of emergency stop devices compliant with GB 16754. Electrical systems must prevent electric shock and eliminate static electricity accumulation on blasting hoses. The standard sets specific noise limits for equipment under no-load conditions and during operation. Furthermore, it requires effective ventilation and dust removal systems. When processing combustible dust, equipment must implement strict explosion-proof measures, including static grounding and pressure relief ports.

Métodos de ensaio

Compliance is determined through a prioritized sequence of methods: functional testing, measurement using instruments, calculation and/or drawing analysis, and visual observation. These methods ensure that all safety requirements are verified practically or theoretically.
