Cette norme doit être appliquée conjointement avec l'EN 1034 1:2000+A1:2010. Elle traite de l’ensemble des phénomènes dangereux et situations et événements dangereux qui concernent les ateliers de raffinage, quand ceux-ci sont utilisés normalement et dans les conditions prévues par le fabricant (voir Article 4).
Cette norme n'est pas applicable aux piles raffineuses.
Cette norme n'est pas applicable aux machines qui ont été fabriquées avant la publication de la présente norme par le CEN.

Ta evropski standard se uporablja za nizkokonsistenčne naprave za mletje, tj. naprave, ki delujejo s suspenzijami vlaken primarne papirne kaše, mehanske lesovine ali razbarvane papirne kaše v vodi s konsistenco do približno 6 %, ki se uporabljajo v postopku izdelave papirja in velja skupaj s standardom EN 1034-1:2000+A1:2010. Opisuje večja tveganja, nevarne situacije in nevarne dogodke v zvezi z napravami za mletje, kadar se uporabljajo v skladu z njihovim namenom in pod pogoji, ki jih določa proizvajalec (glejte točko 4). Ta standard se ne uporablja za stepalnike. Ta dokument se ne uporablja za stroje, izdelane preden je CEN izdal ta dokument.

Overview

EN 1034-8:2012 - Safety of machinery - Safety requirements for the design and construction of paper making and finishing machines - Part 8: Refining plants (CEN) specifies safety requirements for low consistency refining plants used in paper making. It applies to plants processing fibre suspensions (virgin pulp, mechanical wood pulp or deinking pulp) in water up to approximately 6% consistency, and is intended to be used together with EN 1034-1:2000+A1:2010 (common requirements). The standard is a type C standard (per EN ISO 12100) and addresses significant hazards when equipment is used as intended. It does not apply to beaters or to machines manufactured before publication.

Keywords: EN 1034-8:2012, refining plants, safety of machinery, paper making, low consistency refining, CEN standard

Key topics and technical requirements

EN 1034-8:2012 focuses on practical machine safety measures and contains requirements and verification methods for:

• Hazard identification and list of significant hazards specific to refining plants (mechanical, electrical, thermal, noise, material hazards and ergonomics).
• Workplaces and access: safe walkways, platforms, fall protection, lighting and ergonomic design.
• Emergency stop and control systems: emergency stop design (EN ISO 13850), control logic, actuators and measures against unexpected start‑up.
• Power, temperature and pressure control: monitoring and limiting systems for drives, lubrication and stock temperature.
• Refining gap adjustment: safe adjustment procedures and guarding for refiner tools and fillings.
• Energy isolation and lockout measures: prevention of unexpected start‑up and energy dissipation for maintenance.
• Electrical, hydraulic and pneumatic equipment: safe design and compliance with relevant electrical and fluid‑power standards.
• Stock pumps, piping and gate valves: guarding, marking and protection against ejection or leaks.
• Noise and hot surfaces: identification, reduction and marking requirements.
• Verification and documentation: tests, risk reduction validation, instruction handbook and marking for safe use.

Practical applications

This standard is practical for ensuring machine safety and legal compliance in the paper industry. Typical uses:

• Designing and building low consistency refining plants to meet European safety requirements
• Performing risk assessments and machine validation for refining equipment
• Preparing technical files, user manuals and CE conformity documentation
