 Very Happy  
 
 Madan,  I  have  no  background  what  so  ever  to  Gas  &  Cylinders...It  is  just  a  curiosity...I  could  be  utter  dump  in  my  questions  and  statements...
 
 I  just  did  a  search  on  my  computer  and  found  a  document  where  I  read  .75  ratio  as  maximum  filling  ratio..
 
 I  am  posting  the  exact  content  from  one  of  the  sections  from  the  the  doc  ...I  remember  reading  this  in  many  other  doc  as  well...Not  sure  if  .75  ratio  refers  to  something  else...
 
 10.7  Carbon  Dioxide  Cylinders
 1.  The  Dangerous  Goods  (Class  2  -  Gases)  Regulations  require  the  following  for
 carbon  dioxide  cylinders:
 Minimum  Test  Pressure  22  MPa  (3190  psi  224  kg/cm2)
 Maximum  Filling  Ratio  0.75
 This  applies  without  exception  to  all  cylinders  (including  fire  extinguisher
 cylinders)  manufactured  after  March  1980.  Such  cylinders  must  also  comply  with
 the  Regulations  in  all  other  respects  and  must  be  stamped  with  LAB  number.
 2.  Cylinders  manufactured  before  March  1980,  to  an  approved  specification,  which
 have  test  pressures  of  22  MPa  or  greater  and  which  otherwise  comply  with  the
 Regulations  may  also  be  filled  to  a  maximum  filling  ratio  of  0.75.
 3.  Cylinders  manufactured  before  March  1980,  which  have  a  test  pressure  of  less
 than  22  MPa,  may  be  filled  with  carbon  dioxide  in  accordance  with  the  following:
 (i)  Cylinders  which  have  been  approved  and  allocated  LAB  number.
 72  Revised  edition  1992
 ARCHIVE
 (ii)  Other  cylinders  (except  fire  extinguisher  cylinders)  which  comply  with  ALL
 of  the  following  conditions  may  be  filled  to  a  maximum  filling  ratio  of  0.667:
 (a)  Manufactured  to  an  approved  specification.
 (b)  A  test  pressure  of  not  less  than  19  MPa  (2760  psi,  194  kg/cm2).
 (c)  Comply  in  all  other  respects  with  the  Regulations.
 (d)  Are  painted  aluminium  on  the  top  (neck)  half  and  black  on  the  bottom
 half  with  the  legend  â€œFill  .667  CO2”  stencilled  in  red  letters  at  least
 50  mm  high,  parallel  with  the  longitudinal  axis  in  two  places  on  opposite
 sides  of  the  cylinder.
 (e)  Have  a  collar  retained  by  the  valve,  of  a  durable  material,  such  as
 aluminium,  stamped  with  the  legend  CO  2.667  in  letters  at  least  6  mm
 high.
 4.  Except  as  otherwise  approved  in  writing,  portable  fire  extinguisher  cylinders  are
 to  be  filled  to  a  maximum  filling  ratio  of  0.667.  Pre-1980  cylinders  must  have  a
 test  pressure  of  not  less  than  19  MPa.

PostPosted: Mon Jun 23, 2008 3:07 pm Post subject: Re: Co2 Cylinders Reply with quote

 The  following  content  provided  some  relief  to  the  conflict  we  have  
 
 7.3  3  Requirements  for  Particular  Gases
 (i)  Carbon  dioxide
 A  maximum  filling  ratio  of  0.75  and  a  minimum  cylinder  test  pressure  of  22  MPa  are
 specified  in  Regulation  19.  Dispensations  have  been  granted  for  the  filling  of  some
 cylinders  which  were  imported  before  March  1980,  which  have  a  lower  test  pressure.
 This  has  included  the  condition  that  the  filling  ratio  be  a  maximum  of  0.667  (see  10.7).
 Cylinders  that  are  to  be  used  outside  New  Zealand  (e.g.  on  board  ships)  should  generally
 be  filled  to  a  filling  ratio  of  0.667.  This  is  because  they  may  experience  temperatures  far
 higher  than  those  in  New  Zealand.

 
 Now  I  understand  from  where  the  conflict  of  2/3  or  3/4  comes,  it  depends  on  
 
 1)   the  test  pressure  of  the  cylinder.
 2)  Cylinders  used  in  ships  and  high  temperature  regions...

 Ok,  This  is  New  Zealand's  version  of  ISI  Very Happy,  and  is  for  fixed  cylinders  applications,  possibly  due  to  the  ambient  storage  temperatures  never  exceeding  the  Critical  Temperature  of  CO2  in  that  country.
 
 Wonder  if  they  have  modifications  to  this  after  Global  Warming!  Very Happy

 Hi  all,
   Â   I  recently  purchased  a  9  Kg  cylinder  from  a  shop  selling  Co2  for  soda  makers.  Paid  Rs.250.00  for  Co2.  And  the  next  filling  i  have  to  pay  just  Rs.250.00.  
   Â   Â   Â   Â The  next  filling  will  be  after  a  year  or  so,  since  1  bubble  per  second.
 My  friend  advised  me  to  check  that  the  cylinders  are  not  welded  anywhere.
 They  should  be  in  single  moulded  piece.

 I  think  this  should  be  of  interest  to  anybody  using  Co2  Cylinders.
