Free to use BIM project management tool provides step-by-step help to define, manage and validate responsibility for information development and delivery at each stage of the asset life cycle in level 2 BIM projects.
Although we endeavour to maintain an up-to-date catalogue, on occasion we may not have the latest version of a document, including where it has not yet been provided through an international feed. Users of British Standards should make sure that they possess the latest amendments or editions l t is the constant aim of BSI to improve the quality of our products and services We would be grateful if anyone finding an inaccuracy or ambiguity while using this British Standard would inform the Secretary of the technical committee responsible, the identity of which can be found on the inside front cover Tel: Equipment switched off until the flnal hour.
Standards are also available from the BST website at httn: The chromaticity for the colours of the colour class C2 shall conform 10 Table 3. You may wish to search for a more up to date equivalent.
Document Status Indicators The Green document status indicator indicates that the document is: In order 10 limit measuring errors 50me angles are limited. B Objecl of Ihe lest: Intermediate measurements None Final measurements: The Amber document status indicator indicates that some caution is needed when using this document – it is either: The square area around each elemenl is the equivalent elemenl area.

None Th, equipmenl shall b, switched OFF. Sometimes one or more VMS can be fitted into a panelwhich can posSibly al50 display fixed text andfor symbols. Their committees work with the manufacturing and service industries, government, businesses and 122966 to facilitate the production of British, European and International standards. The luminance ralio values shalt be maintained for all illuminances between Ix and 40 Ix. The luminance, measured in cdlm2, is the light intensity per illuminated area in this case the equivalent area of each element Figure A.
These effects shall be tested by either conducting the dry bd test or the solar radiation tesl for Class T1 only.
In generallhe perceived size is larger than the physicat size. Duration of condilioning 90 min in each of 3 axes.

Details the performance requirements for Variable Message Signs used for the instruction and guidance of road users on public and private land, including tunnels. Supplied sources shall be suilably aged so Ihat Iheir eleclrical and optical characlerislics are as slable as possible. Test melhods – Test Fh: Humidity conditions No requirement Test duration: Damp heat, cyclic 12 plus 12 hour cycle IEC This has consequences for the perceived dimensions of message.

Marking required by enn documen! The manufacturer shall state in delaiJ each of the settings for all parameters relevant for the various tests 9. Factory production conlrol EN Want access to British Standards? The manufacturer should detail al1 steps laken 10 comply with this 4 www. Visual inspection and Function Test. As em consequence of this the letler will not have a sharp outline.
The test angles are dependent on the beam width classsee 7.
It is incorporated by Royal Charter Revisio ns British Standards are llpdated by amendment or revision. Each beam width class is delermined by a se!

To achieve this effect the combination of luminance and element spacing shall be balanced. For the observer the lighl witl be em around the cenlre of the element. The equivalent width of the test matrix we is 5 x 38,1 ‘” ,5 mm.

It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used. The minimum luminance at within the beam width angles shall not be lower than 0,5 x: Variable message traffic signs.
Finished VMS shall be c1early, durably and visibly marked with the following information a name or identifying mark of vs manufacturer; b name and registered address of the manufacturer; c product name and i! Final measurements Visual inspection and Function test Pre-conditioning None.
The luminous intensity of the elements shalt be known. It is essential that all materials and manufacturing processes take 1his into account.
