Adjust its position by pushing the back portion into the back, so levering the seat portion forwards until the
shape of the loading point template correlates with that of the seat. In cases where the loading point template
can be settled in more than one position, the position having the smallest angle between the seat and back
portions of the loading point template shall be used.
The angle shall in no cases be less than 90°.
Mark the loading points from the loading point template.
When a seating has more than one sitting place, repeat the procedures on the other sitting places. If the
number of sitting places in the seating is not obvious, divide the total seat length (in millimetres) by 600 and
round to the nearest whole number to determine the number of places. Divide the total seat length into that
number of places of equal length.

「SIST EN 1022:2006」は、家庭用家具の座席に関する非常に重要な欧州標準であり、特に大人向けの全タイプの座席の安定性を評価するための試験方法と要件を定めています。この標準は、家庭用座席が適切に設計されているかどうかを確認するための基準を提供し、消費者の安全を確保する上で重要な役割を果たしています。 この標準の範囲は広く、安定性を決定するための実験的方法と計算的方法の両方を含んでいます。両者は同じ力に基づいており、力の作用点も共通しています。実験的方法は、結果が不確実または限界に近い場合に使用されるべきであり、これによりより正確な評価が可能になります。特に、可変ジオメトリの座席や、荷重がかかると目に見えてたわむ座席には計算的方法が適用されない点が、この標準の強みと言えます。 また、「SIST EN 1022:2006」は、背もたれの角度が10度以下の調整可能なジオメトリの座席には適用されないことを明示しており、この明瞭な範囲設定がユーザーの混乱を防ぎます。審査基準の厳密さと明確性は、この標準の信頼性を高めています。 総じて、「SIST EN 1022:2006」は、家庭用家具の座席の安定性を評価するための堅実で信頼性の高い基準であり、その重要性は家庭用製品の安全性を向上させることに直結しています。また、消費者及び製造業者にとって、安定性の確認は不可欠なプロセスであり、この標準がそれをサポートしている点は、既存の安全基準に対する強力な補完となっています。
The EN 1022:2005 standard provides a crucial framework for assessing the stability of domestic furniture, specifically focusing on seating designed for adult use. This standard is particularly relevant as it establishes rigorous test methods and requirements that ensure safety and reliability in seating stability, which is a fundamental aspect of furniture design. One of the strengths of this standard lies in its clear delineation of the methodologies for determination of stability. By offering both experimental and calculative methods, EN 1022:2005 allows for flexibility in testing approaches while maintaining consistent outcomes. The experimental method provides an empirical assessment, which is critical for verifying the stability of seating designs that may not conform to predictable patterns. Conversely, the calculative method helps streamline the testing process for standard models that fit specific criteria, though it is judiciously limited to non-variable geometry seating to avoid inaccuracies. The exclusion of adjustable geometry seating with minimal backrest angles from its scope signifies a targeted approach, as these designs often present unique challenges in terms of stability. This focus ensures that the standard is applicable to a wide range of typical domestic seating, addressing a significant segment of the market where consumers prioritize safety and durability. Moreover, the provision that mandates re-evaluation of results when the calculative method yields uncertain outcomes underscores the standard's commitment to thoroughness and accuracy. By advocating for immediate verification through experimental methods when results are marginal, EN 1022:2005 not only enhances safety standards but also fosters a culture of accountability among manufacturers. In summary, the EN 1022:2005 standard is integral to the domestic furniture industry, offering relevant, clear, and robust guidelines for assessing seating stability. Its thoughtful inclusions, exclusions, and methodological frameworks serve to advance quality and safety in furniture design, catering to both consumer needs and regulatory compliance.
표준 EN 1022:2005는 가정용 가구, 특히 성인을 위한 좌석의 안정성을 결정하기 위한 시험 방법과 요구 사항을 규정하고 있습니다. 이 유럽 표준은 성인 좌석의 모든 유형에 적용되며, 특히 좌석의 안정성을 평가하는 데 중요한 역할을 합니다. 이 표준의 강점 중 하나는 실험적 방법과 계산적 방법 모두를 통해 안정성을 평가할 수 있다는 점입니다. 두 방법 모두 동일한 힘과 작용 점을 기준으로 하여, 신뢰성 있는 결과를 제공합니다. 계산적 방법은 일반적인 좌석에 적용할 수 있지만, 가변 기하학적 구조를 가진 좌석이나 하중을 받을 때 눈에 띄게 굽어지는 좌석에는 적용되지 않는다는 점에서 전문성과 적합성을 보여줍니다. 또한, 계산적 방법의 결과가 불확실하거나 경계선에 해당하는 경우, 가능한 경우 실험적 방법을 통해 결과를 확인해야 한다는 점에서 안전성과 신뢰성을 보장하려는 노력이 엿보입니다. 이러한 규정은 가정용 가구의 안정성을 직접적으로 다루므로, 소비자 보호 및 제품의 품질에 중요한 영향을 미칩니다. EN 1022:2005는 현대 가정에서 사용되는 다양한 유형의 좌석에 일관된 안정성 요구 사항을 제공하며, 이는 제조업체들이 제품 설계 및 생산 과정에서 고려해야 할 필수 요소입니다. 이러한 표준이 존재함으로 인해 가정용 가구의 안전성과 소비자 신뢰도를 높이는 데 기여하고 있습니다.
La norme EN 1022:2005, intitulée "Mobilier domestique - Sièges - Détermination de la stabilité", constitue une référence essentielle dans le domaine des meubles domestiques. Son objectif principal est de définir les méthodes d'essai et les exigences pour évaluer la stabilité de tous types de sièges domestiques destinés aux adultes. Cela inclut une série de critères qui garantissent la sécurité et la durabilité accrue des meubles, répondant ainsi aux attentes des consommateurs. L'un des points forts de cette norme réside dans sa clarté et sa rigueur. Les méthodes de test proposées – qu'elles soient expérimentales ou calculatives – donnent un cadre précieux pour mesurer la stabilité. Cette double approche permet de s'assurer que les résultats sont fiables et valides. En effet, la flexibilité d'utiliser soit une méthode expérimentale soit une méthode de calcul accroît la pertinence de la norme, puisqu'elle s'adapte à divers types de mobilier. Cependant, il est fondamental de noter que la norme ne s'applique pas aux sièges à géométrie réglable, en particulier ceux dont le dossier forme un angle de 10º ou moins par rapport à l'horizontal. Cette exclusion limitative permet de concentrer l'évaluation sur des sièges plus traditionnels, assurant ainsi que les méthodes de test soient adaptées à la majorité des cas d'usage domestique. Un autre aspect important est que, lorsqu'il existe une incertitude concernant les résultats de la méthode calculative, il est recommandé de procéder à une vérification par la méthode expérimentale. Cela souligne l'engagement de la norme envers la sécurité et le souci de valider les résultats pour éviter tout risque potentiel lié à la stabilité des sièges. En définitive, la norme EN 1022:2005 est d'une grande pertinence dans l'univers du mobilier domestique, car elle établit des exigences claires pour garantissant une évaluation fiable de la stabilité des sièges, tout en intégrant les meilleures pratiques en matière de test et de validation.
Die Norm EN 1022:2005, tituliert "Hausmöbel - Sitzmöbel - Bestimmung der Stabilität", legt einen klaren Rahmen für die Tests und Anforderungen zur Bestimmung der Stabilität aller Arten von Sitzmöbeln für Erwachsene fest. Diese europäische Norm ist besonders relevant, da sie wesentliche Kriterien für die Sicherheit und Zuverlässigkeit von Sitzmöbeln definiert, die in privaten Haushalten verwendet werden. Ein wichtiger Aspekt der Norm ist die Unterscheidung zwischen verschiedenen Sitzmöbeltypen. Die Norm umfasst jedoch nicht verstellbare Sitzmöbel, deren Rückenlehne einen Winkel von 10º oder weniger zur Horizontalen hat, was die Anwendbarkeit der Norm auf flexible Sitzlösungen einschränkt. Diese spezielle Einschränkung hilft, Missverständnisse in der Anwendung der Prüfmethode zu vermeiden und sorgt dafür, dass die getesteten Modelle den Anforderungen realer Nutzungsszenarien entsprechen. Die Feststellung der Stabilität kann gemäß dieser Norm entweder durch experimentelle oder durch rechnerische Methoden erfolgen. Beide Methoden basieren auf denselben Kräften und Anwendungsstellen, was die Vergleichbarkeit der Ergebnisse erhöht. Besonders hervorzuheben ist die rechnerische Methode, die jedoch nicht auf Sitzmöbel anwendbar ist, die eine variable Geometrie aufweisen oder sichtbar unter den aufgebrachten Lasten nachgeben. In Fällen, in denen die Ergebnisse der rechnerischen Methode unsicher oder grenzwertig sind, fordert die Norm eine Überprüfung durch die experimentelle Methode. Dieses Vorgehen zeigt die Stärke der Norm, da sie sicherstellt, dass die Stabilität von Sitzmöbeln zuverlässig und genau bewertet wird. Zusammenfassend lässt sich sagen, dass die Norm EN 1022:2005 einen entscheidenden Beitrag zur Sicherheit und Qualität von Sitzmöbeln im häuslichen Bereich leistet. Ihre Methoden zur Bestimmung der Stabilität sind klar definiert und bieten sowohl Herstellern als auch Verbrauchern eine wertvolle Orientierung, um die Sicherheit und Funktionalität von Sitzmöbeln zu gewährleisten.
