Furniture - Beds and mattresses - Test methods for the determination of functional characteristics and assessment criteria

This European standard specifies test methods for the determination of the durability and hardness of mattresses and all types of fully erected beds with mattresses (and mattress pads when they form a unit with the mattress). It does not apply to water beds, air beds and children cots.
It includes a method for the determination of the firmness rating of a mattress or a bed correlating to the subjective assessment made by people (see Annex A). It must be emphasized that the firmness rating cannot be used to demonstrate comfort and/or quality of a mattress or a complete bed.
Ageing and degradation caused by air, light, humidity and temperature is not included. The test results are only valid for the article tested. When test results are intended to be applied to other similar articles, the test specimen shall be representative of them.

Möbel - Betten und Matratzen - Prüfverfahren zur Bestimmung der funktionellen Eigenschaften und Leistungskriterien

Diese Europäische Norm legt Prüfverfahren fest, anhand derer die funktionellen Eigenschaften von Matratzen und allen Arten von vollständig zusammengesetzten Betten mit Matratzen (und Matratzenpolstern, wenn sie eine Einheit mit der Matratze formen) bestimmt werden. Diese Norm gilt nicht für Wasserbetten, Luftmatratzen und Kinderbetten.
Diese Norm schließt ein Verfahren zur Beurteilung der Härte einer Matratze oder eines Liegesystems hin-sichtlich der subjektiven Einschätzung durch Personen ein (siehe Anhang A). Die gemessene Härte hat kei¬nen Bezug zur Bequemlichkeit und/oder Qualität einer Matratze oder eines kompletten Bettes.
Zersetzung und Alterung, die durch Luft, Licht, Luftfeuchte und Temperatur verursacht wird, ist nicht ent-halten. Die Prüfergebnisse sind nur für den Prüfgegenstand gültig. Wenn die Prüfergebnisse zur Anwendung auf ähnliche Artikel bestimmt sind, sollte der Prüfgegenstand für diese Artikel repräsentativ sein.

Meubles - Lits et matelas - Méthodes d'essai pour la détermination des caractéristiques fonctionnelles et critères d'évaluation

La présente Norme européenne spécifie les méthodes d'essai permettant de déterminer la durabilité et la dureté des matelas et de tous types d'ensembles de couchage en situation d'utilisation intégrant un matelas (et un surmatelas dans le cas où il constitue un ensemble avec le matelas principal). Cette norme ne s'applique pas aux lits à eau, aux matelas pneumatiques et aux lits d'enfants.
Elle inclut une méthode d'évaluation de l’indice de fermeté d'un matelas ou d'un ensemble de couchage en relation avec l'appréciation subjective des utilisateurs (voir Annexe A). Il faut souligner que l’indice de fermeté ne peut pas être utiliser pour prouver le confort et/ou  la qualité du matelas ou de l’ensemble de couchage.
Le vieillissement ou le constat de dégradations dues à l'action de l'air, de la lumière, de l'humidité et de la température ne sont pas pris en considération. Les résultats des essais ne sont valables que pour le produit soumis à essai. Si les résultats d'essai doivent être utilisés pour caractériser un produit similaire, il convient que l'échantillon testé soit représentatif du produit concerné.

Pohištvo - Postelje in posteljni vložki - Preskusne metode za ugotavljanje funkcionalnih značilnosti in kriteriji ocenjevanja

Ta evropski standard določa preskusne metode za ugotavljanje trajnosti in trdnosti posteljnih vložkov in vseh vrst sestavljenih postelj s posteljnimi vložki (in posteljnimi nadvložki, ko tvorijo celoto s posteljnimi vložki). Ne velja za vodne, zračne in otroške postelje. Vključuje metodo za ugotavljanje ocene trdnosti posteljnega vložka ali postelje v povezavi s subjektivno oceno ljudi (glejte Dodatek A). Treba je poudariti, da se ocena trdnosti ne sme uporabljati za prikaz udobja in/ali kakovosti posteljnega vložka ali celotne postelje. Staranje in razkroj zaradi zraka, svetlobe, vlage in temperature ni vključeno. Rezultati preskusa veljajo le za preskušene izdelke. Ko se rezultati preskusa nameravajo uporabiti pri podobnih izdelkih, mora biti testni primerek njihov predstavnik.

1 Scope

This European Standard specifies test methods for the determination of the durability and hardness of

mattresses and all types of fully erected beds with mattresses (and mattress pads when they form a unit with

the mattress). It does not apply to water beds, air beds and children cots.

It includes a method for the determination of the firmness rating of a mattress or a bed correlating to the

subjective assessment made by people (see Annex A). It needs to be emphasized that the firmness rating

cannot be used to demonstrate comfort and/or quality of a mattress or a complete bed.

Ageing and degradation caused by air, light, humidity and temperature is not included. The test results are

only valid for the article tested. When test results are intended to be applied to other similar articles, the test

specimen shall be representative of them.
2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and are

indispensable for its application. For dated references, only the edition cited applies. For undated references,

the latest edition of the referenced document (including any amendments) applies.

EN 1334, Domestic furniture — Beds and mattresses — Methods of measurement and recommended

tolerances

EN 1725:1998, Domestic furniture — Beds and mattresses — Safety requirements and test methods

3 Terms and definitions

test simulating the repeated application of loads and/or movement of components occurring during long-term

use and assessing the strength of the article under such conditions and is a test is a procedure mainly

intended to evaluate the change of the properties of the test unit caused by repeated loadings

3.3
load/deflection curve

curves that are obtained by pressing a load pad into the test unit and measuring the associated value of

indentation and force simultaneously

3.6
height loss
change in the height of a test unit, in mm, caused by the durability test
4 General test conditions
4.1 Preliminary preparation

Unless otherwise specified by the manufacturer, the test unit shall be conditioned for at least one week in a

standardised climate of (23 ± 2) °C and (50 ± 5) % RH immediately prior to testing. Subsequent conditioning

shall also take place in this climate.

The tests shall be carried out at indoor ambient conditions but if during a test the temperature is outside the

range 15 °C to 25 °C the maximum and/or minimum temperature shall be recorded in the test report.

During conditioning and handling, mattresses shall be kept flat and unloaded.

If a test cannot be carried out as specified in this European Standard, e.g. because a loading pad cannot be

used for the application of a force due to the design of a product, the test shall be carried out as far as

possible as specified.

Complete beds shall be tested as delivered. Knock-down type beds shall be assembled according to the

instruction supplied with the test unit. If the test unit can be assembled or combined in different ways, the most

adverse combination shall be used for the test. Knock-down fittings shall be tightened before testing.

If necessary, mattress pads shall be prevented from moving during testing by a suitable means, e.g. adhesive

tape or pins.

In cases where bed bases are adjustable in hardness, the setting during the test shall be recorded in the test

report.

If the production information states that the mattress has a soft side and a firm side, both sides shall be tested

using separate mattresses.
4.2 Tolerances

Unless otherwise stated the following tolerances are applicable to the test equipment:

a) all forces shall have an accuracy of ± 5 % of the nominal force;
b) all masses an accuracy of ± 0,5 % of the nominal mass;
c) all dimensions an accuracy of ± 1 mm of the nominal dimension;
d) the tolerance for position of loading
