National foreword

This British Standard is the official English language version of

EN 14836:2005 It partially supersedes BS 7044-2.4:1989 (replacing method 4) EN 14836:2005 is one of a package of standards being produced by CEN/TC 217 On publication of the entire package, BS 7044 will be withdrawn The UK participation in its preparation was entrusted to Technical Committee PRI/57, Surfaces for sports areas, which has the responsibility to:

— aid enquirers to understand the text;

Foreword

This European Standard (EN 14836:2005) has been prepared by Technical Committee CEN/TC 217

“Surfaces for sports areas”, the secretariat of which is held by BSI

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2006, and conflicting national standards shall be withdrawn at the latest by June 2006

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom

1 Scope

This European Standard specifies a method for the exposure of synthetic surfaces for outdoor sports areas to

artificial weathering in order that the resulting changes in properties can be determined as detailed in the

relevant product specification

The following referenced documents are indispensable for the application of this European Standard For

dated references, only the edition cited applies For undated references, the latest edition of the referenced

document (including any amendments) applies

EN ISO 4892-1:2000, Plastics – Methods of exposure to laboratory light sources – Part 1: General guidance

(ISO 4892-1:1999)

EN ISO 4892-2:1999, Plastics – Methods of exposure to laboratory light sources – Part 2: Xenon-arc sources

(ISO 4892-2:1994)

EN ISO 4892-3, Plastics – Methods of exposure to laboratory light sources – Part 3: Fluorescent UV lamps

(ISO 4892-3:1994)

3 Principle

Specimens are exposed to UV radiation under controlled environmental conditions

NOTE Fluorescent UV lamps use the emission from a low-pressure mercury arc to excite a phosphor that produces a

continuous spectrum in a relatively narrow wavelength interval, which is generally distributed about a peak wavelength

The spectral distribution of the radiation from a fluorescent lamp is determined by the emission spectrum of the phosphor

and the UV transmission properties of the glass tube Fluorescent UV lamps are generally used to expose material to UV

radiation in a limited spectral range

4 Apparatus

Artificial weathering cabinet using fluorescent UV lamps and environmental control having the following

features

a) UV-A 340 nm lamps, in accordance with EN ISO 4892-3 and capable of uniformly applying radiation to

the test specimen at an irradiance of 0,80 W/(m2/nm) (at 340 nm)

NOTE 1 As many fluorescent lamps age significantly with extended use, the apparatus manufacturer's instructions on

the procedure necessary to maintain the desired irradiance should be followed

NOTE 2 The use of UV-B fluorescent UV lamps or exposure in a xenon arc artificial weathering cabinet is

recommended when developing or assessing products intended for installation in environments where high levels of UV

exposure might be expected

b) Exposure chamber, constructed from inert material and that provides uniform irradiance in accordance

with item a) and that includes a means of controlling the temperature

c) Wetting mechanism, either condensation or water spray, to wet the exposed face of the specimen In

apparatus designed to wet the exposed faces of the specimens by means of a humidity-condensing

mechanism, the water vapour shall be generated by heating water in a container located beneath and

extending across the whole area occupied by the specimens Specimen holders (completely filled with

specimens) shall constitute the sidewall of the exposure chamber, so that the backs of the specimens are

EN 14836:2005 (E)

5

exposed to the cooling effect of the ambient room air If wetting is provided by spraying the specimens, the water shall conform to EN ISO 4892-2:1999, 4.6

d) Radiometer, conforming to EN ISO 4892-1:2000, 5.1.7, to monitor irradiance and radiant exposure

e) Black-panel thermometer, conforming to EN ISO 4892-1:2000, 5.2.2

f) Specimen holders, made from inert materials that will not affect the results of the exposure The holders

shall be mounted so that the exposed face of the specimen is located in accordance with the manufacturer’s instructions, and shall be no more than 50 mm from the UV lamp bank plane

The exposure cycle shall comprise (240 ± 4) min of dry UV exposure at a black-panel temperature of (55 ± 3) °C, followed by (120 ± 2) min of condensation exposure, without radiation, at a black-panel temperature of (45 ± 3) °C If sample wetting is by condensation, allow at least 120 min per interval to ensure attainment of equilibrium This time does not form part of the exposure cycle

6 Specimens

Specimens shall be of the size specified by the test methods for the properties to be measured after exposure,

as detailed in the relevant product specification

7 Procedure

Mount the specimen without strain in the specimen holders with the test surface facing the lamps Fill any spaces, using blank panels, to ensure uniform exposure conditions

Expose the specimen, measuring the irradiance and radiant exposure at the surface of the specimen After

an exposure of (4 896 ± 125) kJ, carefully remove the specimen from the exposure cabinet and test as required by the product specification

NOTE An exposure of (4 896 ± 125) kJ will require approximately 2 000h UV exposure and takes approximately 3

000 h with cycling to complete
