Overview

EN 1247:2004/FprA1 is a European safety standard specifically addressing the safety requirements for foundry machinery. This includes ladles, pouring equipment, centrifugal casting machines, and continuous or semi-continuous casting machines. Developed by the Technical Committee CEN/TC 202, this standard is a type C safety standard under EN ISO 12100, aimed at minimizing hazards associated with machinery used in metal foundry operations.

This standard supports compliance with the Machinery Directive 2006/42/EC, ensuring conformity with essential safety requirements for machinery within the European Union and the European Free Trade Association. It also updates and amends the original EN 1247:2004 standard, reflecting the latest safety practices and technical requirements for foundry equipment.

Key Topics

• Safety Requirements for Foundry Machinery: EN 1247:2004/FprA1 outlines specific safety requirements and protective measures for ladles, pouring equipment, centrifugal casting machines, and continuous/semi-continuous casting machines to reduce risks of burns, crushing, and other industrial hazards.

• Significant Hazards Identification: The standard provides a comprehensive list of significant hazards, hazardous situations, and events related to foundry machinery operation. These include risks from molten metal discharge, molten metal splashing, mechanical movements, and unexpected startup.

• Preventive Measures & Design Principles: Safety provisions include the use of locking devices, dynamically self-locking gears, hold-to-run controls for motorized tilting, safeguarding against unexpected tilting, and ensuring appropriate center of gravity for ladles.

• Risk Assessment & Compliance: The document requires manufacturers to conduct thorough risk assessments according to EN ISO 12100 and apply appropriate Type B and Type C standards such as EN ISO 13849-1 for safety-related control systems and EN 60204-1 for electrical equipment safety.

• Verification Methods: Compliance verification involves multiple methods, including visual inspection, functional tests, measurements, and design documentation checks to ensure safety requirements are met reliably.

• Updated Normative References: The amendment updates numerous normative references to align with the latest machinery safety standards covering aspects like guards (EN 953), emergency stop principles (EN ISO 13850), fluid power safety systems, noise emission (EN 1265), and ergonomics (EN ISO 7731).

Applications

EN 1247:2004/FprA1 is essential for manufacturers, safety engineers, and operators in the metal casting and foundry industry. The standard is applicable to:

• Ladle Design and Operation: Ensuring ladles used in molten metal handling are equipped with self-locking gears and appropriate control systems to prevent unintended metal discharge.

• Pouring Equipment: Establishing safety measures for devices used in metal transfer to mitigate risks linked to human interaction and mechanical failures.

• Centrifugal Casting Machines: Applying safety requirements to prevent hazards during the high-speed casting process involving rapid rotational forces.

• Continuous and Semi-Continuous Casting Machines: Enhancing safety systems to protect personnel and equipment during ongoing metal casting operations.

• Safety Management: Integration into company safety protocols for machine design, installation, maintenance, and operator training to ensure long-term compliance and accident prevention.

Related Standards

This standard is closely linked to several key international and European machinery safety standards, including but not limited to:

• EN ISO 12100 - Safety of machinery - Basic concepts and general design principles
• EN ISO 13849-1 - Safety-related parts of control systems
• EN 60204-1 - Electrical equipment of machines
• EN 953 - Safety guards for machinery
• EN ISO 13850 - Emergency stop principles
• EN 1265 - Noise test code for foundry machines
• EN ISO 7731 - Ergonomics of auditory danger signals
• EN 983 and EN 982 - Safety requirements for pneumatic and hydraulic systems
• EN 349 - Minimum gaps to avoid crushing of human body parts

Utilizing the EN 1247:2004/FprA1 standard alongside these norms ensures a comprehensive approach to machinery safety in the foundry sector, covering mechanical, electrical, ergonomic, and control system hazards effectively.

2 Modification to the Introduction
Replace the existing text with the following:
"This European Standard is a type C standard as stated in EN ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered
are indicated in the scope of this European Standard.
When provisions of this type C standard are different from those which are stated in type A or B
standards, the provisions of this type C standard take precedence over the provisions of the other
standards, for machines that have been designed and built according to the provisions of this type C
standard.
Where for clarity an example of a preventative measure is given in the text, this should not be considered
as the only possible solution. Other solutions can be used as far as they fulfil correctly the criteria
expressed in the requirement.
This European Standard assumes, that the equipment is operated and maintained by trained personnel."
