Europe Issues Revised Seat Stability Test Method Standard EN 1022
The CEN has published an updated version of its standard for seat stability testing – EN 1022. Member States have until May 2019 to publish the new standard and remove conflicting standards.
- (1888PressRelease) December 13, 2018 - The European Committee for Standardization (CEN) has published a revised version of EN 1022, its furniture seating standard to determine stability. The new version, EN 1022:2018, was published on November 14, 2018, and it replaces EN 1022:2005.
The previous version of the standard related only to all seats, except work office seats. The updated version merges the work/office standard with all other seating test standards. It therefore also supersedes EN 1335-3.
The main modifications are:
• New definition added to define specifics of the work seat – specified as a swiveling chair, with or without arm rests. It is used by one adult in the office, whose upper part (which includes the seat and back) is supported on a single column and can rotate in the horizontal plane, and is at least adjustable in height
• To reduce confusion in some designs, the raised edge side definition has been added. This is, a seat where the side edge of the item of seating is higher than 50mm above the height of the seat loading point, and the test method will be adapted for this design
• The loading point for a swiveling chair, including domestic use chair, is defined as the point at which the swiveling seat's axis of rotation intersects with the seat surface. Moreover, the back-loading point is defined as the point on the center line of the backrest, 300 mm above the seat loading point measured when the seat is loaded with 640 N
• A new testing position is defined for the forward stability test for rigid seats with a large radius
• Corner stability test added. Previously only office chairs included this test, so it will impact the domestic chair market
• Clarification between the definition of leg rest and footrest. The footrest is designed to support the user to access the seat of a bar stool, as the leg rest is intended mainly to support the leg. If the leg rest is designed in a way that a user may sit on it, the forward test remains applicable
• Rocking chairs will also be subject to all stability tests. Only the rearward stability test will have to be changed, according to an adapted test
Stakeholders need to be aware of the applicability of certain standards (product, standard, reference in EN 1022, applicability):
• Outdoor seat - EN 581-2:2016 - EN 1022: 2005 - wait for the standard update of the EN 581-2 standard
• Domestic seat - EN 12520: 2016 - EN 1022 (not dated) - right after EN 1022:2018 publication
• Non-domestic seat - EN 16139: 2013 /A1:2013- EN 1022 :2005 is mentioned in the amendement- an amendement needs to be published in order to apply the next version of the EN 1022.
• Office seat - EN 1335 :2018 - EN 1022: 2018 - right after publication
The rule is, when a standard is not dated the most recent version of the standard is applicable.
The new standard was published on November 14, 2018. Member States have until May 2019 to publish the new standard and rescind any previous or conflicting standards.
