Overview - EN 1114-1:2011 (CEN)
EN 1114-1:2011 is the CEN European standard that sets out safety requirements for screw extruders used in the plastics and rubber industries. It specifies the significant hazards, hazardous situations and events relevant to screw extruders when used as intended and under foreseeable misuse. The standard also covers common feeding systems (hoppers, single/double roller feeds, crammer feeders) and ancillary equipment attached to extruders such as screen changers, melt/gear pumps, melt pipes and adaptors, static mixers and extruder heads. Metering devices, explosion hazards (ATEX), fire originating from processed materials and pre‑existing machines are outside its scope.
Key topics and technical requirements
EN 1114-1:2011 organizes safety requirements around major hazard types and machine functions. Important topics include:
- Mechanical hazards: drive and power transmission, screw shaft, barrel openings, feeding systems, screen changers, melt pumps, static mixers, extruder heads, and moving parts protection.
- Electrical safety: requirements for electrical equipment, isolation/disconnect, protection against direct and indirect contact, and electrostatic phenomena.
- Thermal hazards: guarding for hot machine parts, hot extrudate, hot gases and liquids.
- Noise: noise assessment and the included Noise test code (Annex A) for measuring A‑weighted sound pressure and sound power levels.
- Materials-related hazards: guidance on hazards from processed materials (note: specific fire/toxic risks from materials processing are excluded).
- Ergonomics and working at height: design principles to reduce operator strain and fall risks.
- Protective measures and emergency systems: excess pressure protection, emergency stop, verification of conformity, machine marking and instruction manual requirements.
- Conformity and verification: procedures for checks, documentation and information for safe use.
Practical applications - who uses this standard
EN 1114-1 is used by:
- Extruder and extrusion-line manufacturers for safe design and CE‑compliance.
- Machine designers and OEMs integrating feeding systems and ancillary equipment.
- Safety engineers and maintenance teams implementing guards, interlocks, emergency stops and thermal/noise controls.
- Certification bodies and conformity assessors verifying compliance with EU Machinery Directive (see Annex ZA).

SIST EN 1114-1:2011 표준은 플라스틱 및 고무 기계에 대한 안전 요구 사항을 규정하는 유럽 표준으로, 특히 스크류 익스트루더에 관련된 모든 주요 위험 요소와 상황을 포괄적으로 다루고 있습니다. 이 표준의 범위는 다양한 유형의 스크류 익스트루더가 의도한 대로 사용될 때 발생할 수 있는 위험을 식별하는 데 초점을 맞추고 있습니다. 이 표준의 강점 중 하나는 익스트루더와 관련된 모든 주요 위험을 정의하고, 이를 안전하게 다룰 수 있는 지침을 제공한다는 점입니다. 또한 이 표준은 다양한 공급 시스템, 즉 호퍼, 단일 롤러 공급, 이중 롤러 공급, 크래머 공급 장치 및 익스트루더에 부착된 보조 장비를 포함하여 안전 요구 사항을 포괄적으로 다루고 있습니다. 이는 사용자가 최신 안전 기준에 따라 기계를 운영할 수 있도록 한다는 점에서 큰 장점입니다. SIST EN 1114-1:2011 표준은 특정 기준을 충족하는 익스트루더가 압력 용기로 간주되지 않으며, 폭발성 대기가 발생할 가능성이 있는 재료 가공에 대한 규정이 포함되어 있지 않다는 점에서도 중요합니다. 이는 제조업체가 미리 예측할 수 있는 오용 조건에서의 안전성도 고려하였음을 나타내며, 이로 인해 사용자는 더욱 안전하게 장비를 운영할 수 있습니다. 또한 이 표준은 측정 장치에 대한 안전 요구 사항은 포함하지 않고 있으며, 기계의 특정 종류로 제한된 점도 사용자에게 명확한 기준을 제시합니다. 이러한 특성 덕분에 SIST EN 1114-1:2011은 플라스틱 및 고무 산업에서 적용되는 익스트루더의 안전성을 높이고, 관련 작업 환경의 위험성을 줄이는 데 중요한 역할을 하고 있습니다. 이와 같은 강점을 통해 해당 표준은 제조업체와 운영자 모두에게 실질적인 가치를 제공하며, 안전하고 효율적인 생산 환경을 조성하는 데 기여하고 있습니다.
The EN 1114-1:2011 standard provides a comprehensive framework for ensuring the safety of extruders and extrusion lines specifically designed for processing plastics and rubber. The scope of this European Standard is particularly well-defined, as it specifies all significant hazards, hazardous situations, and potential events related to screw extruders, as used in intended applications as well as foreseeable misuse scenarios. One of the notable strengths of this standard is its inclusive coverage of various feeding systems associated with extruders. By addressing hoppers, single and double roller feeds, crammer feeders, and ancillary equipment like screen changers, melt pumps, and static mixers, EN 1114-1:2011 demonstrates a thorough understanding of the machinery's operational context. This ensures that manufacturers and operators are well-informed about the safety requirements across the entire extrusion process chain, promoting a safer working environment. Furthermore, the standard clarifies critical aspects, such as the non-regulation of metering devices, and asserts that extruders as covered within this document do not fall under pressure vessel definitions per the Pressure Equipment Directive 97/23/EC. This distinction helps streamline compliance efforts for manufacturers, emphasizing the specific safety considerations unique to extruders. However, it is essential to note that the EN 1114-1:2011 standard does not address potential hazards arising from material processing that could lead to fire risks or health hazards. This limitation necessitates supplementary guidelines and risk assessments concerning the materials processed. The relevance of EN 1114-1:2011 cannot be overstated; with advances in machinery and processing materials, having a robust safety standard such as this aligns with the industry's growing emphasis on operational safety, compliance, and accountability. Therefore, this standard serves as a pivotal document for manufacturers and operators in the plastics and rubber industry, ensuring that the safety requirements for extruders meet rigorous and accepted benchmarks.
EN 1114-1:2011は、プラスチックおよびゴム機械における押出機および押出ラインの安全要件を定めた重要なヨーロッパ規格です。この文書は、スクリュー押出機に関連するすべての重大な危険、危険な状況、および事件を包括的に明示しており、製造者が予見可能な使用条件および誤使用の状況下での安全性を確保しています。 規格の強みは、その適用範囲にあります。具体的には、ホッパー、シングルローラー供給、ダブルローラー供給、クランマーフィーダーといった供給システムを対象にしている点が挙げられます。また、押出機に取り付けられた付属装置、例えばスクリーチェンジャー、メルトポンプ、メルトパイプ、静的ミキサー、押出機ヘッドなども含まれ、これにより押出機の安全性が一層高まります。 しかし、計量装置についてはこの規格の対象外であるため、ユーザーは別途注意が必要です。また、材料の加工によって生じる危険、例えば火災や健康に有害な物質の放出に関しては、規格の範囲外であることも明確にされています。これは、特に業界において安全対策を講じる際に考慮すべき重要な側面です。 EN 1114-1:2011は、圧力機器指令97/23/ECに基づく圧力容器とは見なされておらず、通常、爆発性雰囲気を生成しないよう設計されていますが、爆発性雰囲気を生じさせる材料を処理する場合には、ATEX指令94/9/ECを適用することが求められます。このように、適用対象が厳密に定められているため、業界における安全性の基準を確立する上で信頼性の高い規格と言えます。 全体として、EN 1114-1:2011は、プラスチックおよびゴム業界における押出機の安全性を確保するための実用的で効果的な指針を提供するものであり、その関連性と重要性は依然として高いものです。
