FIRA STANDARD 6250: 2005 SPECIFICATION: FURNITURE MATERIALS (INTERIOR)

FIRA Standard 6250: 2005 Specification - Furniture Materials (Interior) specifies

requirements and guidance information for the performance of materials ud in interior

furniture, including domestic and contract furniture applications.

The specification is sub-divided into the following sub ctions

Classification: Guidance on rvice u

Specification: Surface finishes.

(e.g. paint, lacquer plastic foil, paper foil, plastics laminate)

2. CLASSIFICATION

Performance requirements for furniture materials are divided into three main classification

ratings with the appropriate rating lected according to rvice u.

Table 1 provides general guidance on the main rvice u applications and recommended

classification rating. Classification ratings for different properties may be mixed according to

requirements. For example an office desk will typically require a ‘vere’ rating for finish

performance and ‘general’ rating for adhesion. (FIRA can advi on the appropriate test

specification for a product).

FREEDOM FROM SHARP EDGES

Finished components shall not have any sharp edges or splinters that are likely to cau discomfort or injury to

persons during normal u of the furniture.

FREEDOM FROM VISUAL DEFECTS:

When components are viewed with normal or corrected vision at 400 ± 200 mm there shall be no obvious defects

that would detract from the appearance of the furniture.

There shall be no obvious joint opening when the sample is viewed with normal or corrected vision at a distance of

400 ± 200mm. Minor hairline thickness cracks are permitted provided they do detract from the visual appearance of

the sample.

The degree of colour change of expod and non-expod areas

is compared with Standard Grey Scales (ISO 105 - AO2) where 1

= maximum colour change and 5 = no colour change.

Timber Source

Moisture Content

Growth defects

Preferably from a 'sustained yield' source. E.g. FSC managed source.

Not a species listed under CITES.

9% ± 2 (at point of manufacture)

Timber other than that intended for appearance ‘rustic’ or ‘hidden’ surfaces shall be

free of major growth defects such as dead knots, knotholes, edge knots, ingrown bark, ring

shake, tension wood, wane, juvenile wood pith, brittle heart, cross grain cracks.

Live knots permitted but not to exceed 2 live knots (maximum diameter 6mm) in any visible

area of the product.

Maximum of 10% sapwood, provided that it is free from fungal stain.

The slope of the grain shall not exceed 1 in 8 when measured from the outside edge of

components.

Not permissible on visible surfaces.

Sapwood

Grain

Rot, mould and fungal

stain

Wood boring incts

‘worm holes’

No live wood boring incts are permissible

No wormholes are permitted on expod surfaces

Up to 10 wormholes, less than 2mm, are permissible on hidden surfaces provided that they are

filled.

Termite damage not permissible

Kiln Drying Defects

Defects due to drying such as shakes, splits, cracks, honey combing and ca hardening not

permissible.

Minor non-structural surface splits and checks permissible on hidden surfaces.

Distortion

≤ 0.5mm variation from the straight per 100mm on any width.

≤ 3mm variation from the straight on any length

*Note: The quality of timber varies significantly according to wood species, price and other processing and grading factors. It

is therefore recommended timber specifications should fully discusd and agreed in detail with the timber supplier.

4. MARKING

TABLE 11: FIRA STANDARD 6250: – MARKING

Each item for which conformity to this FIRA Standard is claimed the following information shall be made available to the

purchar, distributor or retailer.

a) the name, trademark or other means of identification of either the manufacturer, distributor or retailer

b) the number and date of this FIRA Standard, i.e. FIRA Standard 6250 :2005, together with the appropriate performance

test rating /classification

Note: Marking FIRA Standard 6250: 2005 on or in relation to a product reprents a manufacturer's declaration of conformity

that the product meets the relevant requirements of the standard. The accuracy of the claim is therefore solely the

responsibility of the person making the claim. For such a declaration third party certification is desirable
