4.7 Appli cation of signs 
4.7.1  A sign shall be appl ied to a back ing sheet in such a  way that it is symmetrical.  SZNS 044-1:201 5 
Edition 1  
 
8     ©SWASA 2015  – All rights reserved  
  4.7.2 In the c ase of  a standard sign  that is applied to  a plastics backing  sheet, e ach colour of the sign  
shall be of such density as to ensure complete  opacity  after the application of the sign in order to 
prevent  the colour of the underlyi ng backi ng sheet from s howing through the co lour of the sign. 
Overlaid col ours shall  not separate  from the backi ng sheet, and there shall  be no bleeding of colour 
from the b acking s heet. 
4.8 Workmanship  
A sign shall  be free from rough and sharp  edges, warps,  dents, cavities  and other surface 
irregularities. Coated  surfaces shall  be smooth,  free from  grittiness,  runs, sags,  wrinkles, brush marks 
and orange peel. 
4.9 Performance  
4.9.1  Resistance  to immersion  in water 
After the immers ion of a s ign in acc ordance with 5.4,  
a) a coat ed surface  shall  show no s ign of  blister ing, wr inkling or l oss of adh esion;  and  
b) the back a nd all edg es of the si gn shall sh ow no  sign of corr osion. 
4.9.2  Resistance  to artificial  weathering  
When a si gn is tested in accorda nce with 5.5,  
a) the  coati ng  on  the  front  surface  of  each  test  speci men  shall  comply  with  the  following 
requirements:  
1) the coatin g(s) shall  show no sign of cha lking or cracking; and  
2) the chromaticity  co-ordinates of the ordinary surface  colours shall  be within the relev ant 
boundaries in the chrom aticity  diagr am (see  figure 1)  and the lumina nce factor shall be  as given  in 
table  6. For the co-ordinates of the corners  (poin ts of intersecti on) of the regions on the diagram, 
see tab le 6; and  
b) the back a nd all edg es of the si gn shall sh ow no  sign of corr osion. 
4.9.3  Strength  of adhesion  of decals  
When a d ecal is tested in accordance wi th 5.6,  
a) the liner shall  not bre ak or tear or  remove any of the adh esive from  the decal; or b)  the dista nce of 
peeling  shall not exce ed 40 mm.  
5 Inspection and methods of  test 
5.1 Inspection  
Visually  examine  and then measure each sign in the sample  for compl iance with all the appropriate 
requirements for wh ich tests to ass ess complia nce are not given in  5.3 to 5.6 (incl usive).  
5.2 Sequence of testing  
Carry out the tests in the order in which they are give n. 
5.3 Test for chromaticity  and luminance factor  
Use a spectrophoto meter or another suitable  colour meas uring device,  and the method  given in 
CIE publication  15 (E-1.3.1)  and in CIE publication  54.2 to determine the chromaticity  co-ordinat es 
and the luminance factor of the sample (using standard Illumin ant D65 and 45/0 geometr y), and 
check for c omplia nce with  4.6.2.  
5.4 Resistance to immersion in water 
Immerse  each sign for a  period of  24 h in  distilled water  at a temperature  of 25 °C ±  2 °C. Examine 
the sign for  complia nce with 4.9.1( a) and (b). SZNS 044-1:201 5

 5.5 Resistance to artifici al weathering  
5.5.1  Test specimens  
From  each sign used in the test given in 5.3, so cut a test specimen, of size approximately 
150 mm × 70 mm or 100 mm × 70 mm, as to include  as much of each colour on the sign as 
practicable and as many of the edges and  holes as possible. Except  in the case of  plastics signs, seal 
all the  cut edges of e ach sp ecimen.  
5.5.2  Procedure

 Annex B  
(infor mative)  
Quality verification of s ymbolic safety signs  
B.1 Quality verification  
When  a  purchaser  requires  ongoing  verification  of  the  quality  of  symbol ic  safety  signs,  it  is 
suggested that, instead  of concentrating solely  on evaluation  of the final product, he also directs his 
attention  to the manuf acturer 's quality  system.  In this co nnection it should be noted that SZNS ISO 
9001 covers the provision of an integrat ed quality system.                                                                  
B.2 Definitions  
B.2.1 
defective

SZNS 044 
B.2.2 
lot 
as agreed upon between  the testing  facility  and the manuf acturer,  but not more  than 1 000  signs of 
the same type designation, materia ls and size, from  one manufacturer, and submitted  at any one 
time for ins pection a nd testing                                                                                                   
B.3 Sampling and compliance  with this part of SZNS 044  
B.3.1  General  
The following procedure is used for the sampling  for inspection and testing before acceptance or 
rejection  of single lots (c onsignmen ts) in cases where no information about the implementat ion of 
quality contr ol or testing d uring m anufacture is ava ilable to help in assessi ng the quality of the lot.  
B.3.2 Sampling  
The following sampling procedure s hall be applied in determining wheth er a lot complies with  the 
relevant re quirements of this part of SZNS 044 . The samp les so taken shall  be de emed to represent 
the lot for the respective prop erties.  
From  the lot draw at random the number of signs given in column 2 of table  B.1, relative  to the 
appro priate l ot size given in  column 1.  
B.4 Compliance  with this part of SZNS 044  
A lot shall  be deem ed to comply  with the requirements of this part of SZNS 044  if, after inspection 
and testing  of the  sample taken in accorda nce with B.3.2, the number of defect ives found  does not 
exceed the appropriate accept ance n umber giv en in column 3 of table B.1.

Annex C  
     (normati ve) 
  Positioning, fixing, illuminat ion and mainten ance of signs  
C.1 Selection of s ign 
NOTE     Because safety signs should be visib le at all times, self-luminous  signs (see SZNS  044-2) or 
internally illuminated signs (see SZNS 044-3) are preferred  for symbolic  safety signs relating  to fire 
informat ion, emerg ency exits, da nger or warnings.  If these are not available or not cost -effecti ve, retro - 
reflective  (see  SZNS 044-4)  or  photolumines cent  (see  SZNS 044-5)  materi als  should  be  used  in  the 
manufactu re of symbolic safe ty signs re lating  to fire  information, eme rgency exits, d anger or  warnings. 
C.2 Responsib le person  
A suitab le employee shall be made responsible for the corr ect placing of safety  signs. He s hall have 
had g eneral experie nce of safety w orking metho ds 
C.3 Positioning of signs  
C.3.1  A safety sign shall, wherev er possib le, be positi oned in the most  conspicuous position 
available.  
C.3.2 A safety sign s hall be so p laced that it does not crea te a h azard.    
C.3.3 A safety sign shall be  placed  for maximum  effectiveness,  i.e. where  it can be seen readily and  
where it will provide  optimum  warn ing of the presence of a hazard or the presence of rescue and 
fire fight ing equ ipmen t.                                                                                                         
C.3.4 Where  possible, a safety  sign shall  be placed at 90° to the passage  or walkway which it is to 
serve.                                                                                                                                      
C.3.5 Safety signs  to be used in atmos pheres that conta in corrosive  chemica ls shall be made 
from the mo st effective material.                                                                                                 
C.4 Fixing of s igns 
In the case of safety  signs that have  low mechanical strength, the sign shall  be attac hed to a flat 
surface or mounted  on a plate  or in a frame.  In the case of suspended signs, the sign shall be  so 
placed  that it cannot be damag ed accidentally.  When relevant,  nuts,  bolts and wash ers used for 
attachi ng a safety  sign to its support shall be corrosion protected, and  heads of bolts  shall be of the 
same  colour as that of the part of the safety  sign in which they are placed. In the case of safety 
signs made of metal,  suitable  precautions shall  be taken to prevent electrolytic corros ion caused by 
penetration of  moisture into  joints betwe en dissimil ar metals . 
C.5 Illumination of signs  
If natural lighting does not illuminate a safety sign  sufficiently, adequate artific ial lighting s hall be 
provid ed. 
C.6 Maintenance of  signs  
A specific member  of the staff shall  be made  responsible  for the mainten ance and replacement of 
signs. Signs  shall be insp ected regularly and k ept clean and l egible.  
Signs  remo ved during c onstruction w ork shall  be replaced  with temporary si gns positioned as  near 
as practicab le to the original site. Signs that have been so removed or that have been damaged 
shall  be replaced with a minimum  of delay. When relevant,  care shall  be taken to  ensure that a sign 
or its supp ort(s) is/are not impaired d uring repa ir work .
