Guide to Flame Retardancy


Drapes & Sheers

 

For domestic or private use (UK) there are no requirements for flame Retardancy.

In the Contract Environment there are requirements, the main requirements that are requested are as follows:

United Kingdom:

BS5867 Part 2 2008 Type B:

Usage Hotels. Offices. Public Buildings, Libraries etc. Mid to low risk areas

The most common test method (contained in BS5438:1976) being Part 2. The test involves test samples being placed in a vertical plane on a specifically designed test rig, a regulated flame is applied for a set time and the results observed and recorded. Fabric is tested on the face.

Pass criteria: No part of any hole or Flame does not reach edge, No flaming debris.

BS5867 Part 2 2008 Type C:

Usage: Healthcare markets, Hospitals, High risk areas

The most common test method (contained in BS5438:1976) being Part 2. The test involves test samples being placed in a vertical plane on a specifically designed test rig, a regulated flame is applied for a set time and the results observed and recorded. The fabric is tested on both the face and back, and subjected before and after to a cleansing requirement of 50 washes in accordance with BS EN ISO 10528.

Pass criteria: No part of any hole, or flame should reach either edge, No flaming debris. Any afterglow or after flame should cease within 2.5 s.

IMO (International Marine Organisation)

IMO (2010) FTP CODE Annex 1, Part 7. Clause 3:

Usage Marine (Ships) Worldwide.

International code for application of fire test procedures for safety at sea effective 1/7/12(Previous Standard IMO A.471) Edge and surface ignition tests.

Pass criteria: Any after flame must cease within 5s No Flaming Debris, no burn through, and ignition of cotton wool below specimen, average char length in excess of 150mm& surface flash propagation more than 100mm from point of ignition.

USA

NFPA701 Standard methods of Fire Test for Flame Propagation of Textiles and Films 2010 Test #1

Usage Contract Applications.

Weighed sample suspended vertically and flame applied to edge for 45s

Pass criteria: No flaming debris flaming beyond 2s, Mass loss less than 40%, No After flame.

Italy

UNI VF 8456 ‘Classe Uno’

Usage Contract Applications.

Ignition Source Small burner applied to Edge of fabric, small burner ignitability conducted together with surface flame test. Both results determine an overall classification, Class1-5, Class 1 being the best.

Pass criteria: After burn time.

 

Bedspreads/Contract Bedcovers


 

For domestic or private use there are no requirements for flame Retardancy. In the Contract Environment there are requirements, the main requirements that are requested are as follows:

United Kingdom:

BS7175: 1989 Section 3, Ignition Source 5 (Crib 5)

Usage Contract Counterpanes/Bedcovers.

Uses BS7175:1989 test criteria (Crib 5)

Pass criteria: Flaming ceased, after glow ceased, damage not exceeded limits. Tested on a mineral wool fibre pad and subjected to a flaming ignition source/ placed on top & /or below the specimen.

 

Upholstery/Headboards


 

United Kingdom:

The Furniture and Furnishings (Fire) (Safety) Regulations 1988* (As amended in 1989 and 1993) set levels of fire resistance for Domestic upholstered furniture, furnishings and other products containing Upholstery.

Domestic Upholstery:

BS5852: Part 1: 1979 This standard is split into two parts

BS5852: Part 1:1979: Source 0 – commonly called the ‘Cigarette Test’

BS5852: Part 1: 1979: Source 1- commonly called the ‘Match Test’

BS5852: Part 1: contains the method and flammability requirements for upholstery composites exposed to ignition sources 0 & 1 (Cigarette & Match Tests)

For the Cigarette test (Source 0) a cigarette is placed on the fabric at the join of back and seat, to simulate a cigarette being dropped onto the upholstery, for the Match Test (Source 1) a regulated gas flame is placed against the fabric for a specified amount of time this simulates a match being struck and dropped on the upholstery, the events are observed and recorded.

Any fabric used for upholstery in the UK must pass the cigarette test and match test there are several ways this can be achieved dependent on the fabrics composition.

Source 0 Pass Criteria: No Flaming or progressive smouldering.

Source 1 Pass Criteria: Flaming ceases with removal of flame, no progressive smouldering.

Contract Upholstery

BS5852: 2006 Clause II: Source 5- Commonly called ‘Crib 5’

This standard contains the test method for Upholstery composites for Ignition sources 2-7, source 5 (or Crib 5) is a wooden crib, this is placed in the centre of the test rig and the events monitored and recorded, BS7176 sets out the specification for Upholstery and is categorized in three levels

Low: (Domestic) Cig & Match

Medium: (Hotels, Public Buildings, Healthcare) Crib 5

High: Prisons and some hospital situations (Crib 7)

European

BS EN 1021-1 & BSEN1021-2:1994

Basically equivalent to BS5852 Source 0 & 1

Italy

UNI VF 9175 (Upholstery Materials) ‘Classe Uno’

Ignition Source Small burner gas flame applied in fold between seat and back padding.

Pass Criteria: After burn time.

France (Upholstery & Drapes)

NF P92-503-504 (M Rating)

Tests:

Radiation heat test & surface ignition

Classifications Pass Criteria;

Pass Criteria: After burn time Max 5 Secs, Damaged surface, flame spread, burning debris/droplets.

IMO (International Marine Organisation)

IMO (2010) FTP CODE Annex 1, Part 8. (Smouldering Cigarette Test)

IMO (2010) FTP CODE Annex 1, Part 8. (Propane Flame Test)

International code for application of fire test procedures for safety at sea effective 1/7/12(Previous Standard IMO A.652) Face ignition tests.

Pass Criteria: No progressive smouldering or flaming within 1 hour.

Usage Marine (Ships) Worldwide.

German

DIN 4102-1 (B1/2) Fire Tests to Building Material

This German standard defines fire behaviour classes for building materials, specifying test methods for each class.

Class B

Pass Criteria

Burner Flame applied for 15 Secs, Fire Shaft tests Subjected to flame for 10 mins.

Material classified B1 or B2

B2 if the time to meet the marked point is min 20 secs/ No Ignition, Droplets max 2 secs

B1 Is after Fire Shaft test Residual Length is min 150mm, Temp of smoke is Max 200 degrees C.

USA

California Technical Bulletin 117 -2013 Cover Fabric Test (CAL 117)

Mandatory in some states, being adopted countrywide as standard for Upholstery. Cover wrapped around standard foam substrate, cigarette placed at the joint, of seat/back.

Pass Criteria

Smouldering may not continue 45 mins after commencement. Vertical Char may not exceed 1.8 inches, must not transition to open flaming.

 

Wallcoverings


 

European

Harmonised EN 15102:2007 +A1:2011 Decorative Wallcoverings in Roll and Panel Form

The European Standard EN 13501-1 Reaction to Fire provides a number of performance criteria to measure the fire characteristics of building products. These cover spread of flame and contribution to fire as well as the generation of smoke and the production of burning droplets .The fire rating system refers to the requirements in EN 15102 and the EU Construction Product Regulations

Classifications for wallcoverings are B-D, Release of Heat (B = Lowest release D = Highest Release)

s (Smoke 1-3)

d (Burning droplets 0-2)

This creates a ‘Declaration of Performance ‘classification. We currently have products with the following classifications:

Classification Reaction to Fire B-s1, d0 or B-s2, d0

Classification Reaction to Fire D-s3, d2

USA

ASTM E84 Surface Burning Characteristics of building Materials

Test method: a horizontal and a face down sample are exposed to a test flame, for a 10 minute period.

Pass Criteria: From a very complicated formula, a flame spread distance-time relationship is calculated

Class 1-3 Dependent on Flame Spread Index.
