On  September  20,  1937,  the  National  Association  of  Insecticide 
and  Disinfectant  Manufacturers,  Inc.,  proposed  the  establishment  of 
a Commercial  Standard  for  Coal  Tar  Disinfectant  (Emulsifying 
Type).  Accordingly,  after  preliminary  conferences  with  other  in- 
terested organizations,  including  the  Federal  Food  and  Drug 
Administration,  the  proposal  was  submitted  on  March  23,  1938,  to 
manufacturers,  distributors,  and  users  for  the  approval  of  all  con- 
cerned. The  industry  has  since  accepted  and  approved  for  promul- 
gation by  the  United  States  Department  of  Commerce,  through  the 
National  Bureau  of  Standards,  the  standard  as  shown  herein. 

The  standard  became  effective  on  June  10,  1938. 

Promulgation  recommended.

1 . The  purpose  of  this  commercial  standard  is  to  provide  a minimum 
| specification  for  quality,  as  a basis  for  understanding  and  voluntary 
guaranties  between  producers,  distributors,  and  users  in  the  purchase 
of  this  commodity,  and  as  a foundation  for  confidence  on  the  part  of 
purchasers  that  the  efficacy  of  the  material  is  that  which  may  be 
iexpected  of  emulsifying  type  coal  tar  disinfectant  manufactured  in 
conformity  with  a nationally  recognized  specification. 


2.  This  standard  covers  materials,  physical  and  chemical  properties, 
and  certification  of  quality  of  emulsifying  type  coal  tar  disinfectant. 


3.  It  shall  be  made  of  coal  tar  oils  and  acids  and  an  emulsifying 

4.  It  shall  contain  not  less  than  65  percent  by  weight  of  oils  and 
acids  from  coal  tar. 

5.  It  shall  contain  not  over  10  percent  of  water. 

6.  It  shall  not  contain  kerosene  or  other  petroleum  distillates. 

7.  The  phenol  coefficient  shall  be  determined  by  the  Federal  Food 
and  Drug  Administration  method  of  test  against  B.  typhosus  and  shall 
be  clearly  stated  on  the  label  attached  to  each  shipping  container.1 

8.  It  shall  make  milky  emulsions  with  water  of  zero  hardness  at 
20°  C (68°  F)  when  diluted  in  the  ratio  of  5 parts  disinfectant  with 
95  parts  of  water  for  disinfectants  of  phenol  coefficient  10  or  under; 
and  in  the  ratio  of  2 parts  of  disinfectant  to  98  parts  of  water  for  dis- 
infectants over  10  in  phenol  coefficient;  these  emulsions  shall  show 
not  more  than  a trace  of  oily  float  or  sediment  when  stored  for  5 hours 
at  room  temperature. 

9.  It  shall  remain  limpid,  showing  no  sign  of  naphthalene  crystal- 
lization down  to  0°  C in  12  hours. 

10.  It  shall  contain  less  than  5 percent  of  benzophenol. 

11.  The  disinfectant  after  standing  indefinitely,  shall  show  no 
separation,  no  loss  of  germicidal  value,  nor  any  form  of  decomposition 
(such  as  soap  separating  from  the  oil)  under  normal  and  reasonable 
conditions  of  storage. 

1 This  type  of  disinfectant  is  readily  available  with  phenol  coefficients  ranging  from  2 to  20.  Contract 
buyers  should  specify  the  phenol  coefficient  desired.

On  September  20,  1937,  the  National  Association  of  Insecticide 
and  Disinfectant  Manufacturers,  Inc.,  requested  the  establishment  of 
a commercial  standard  for  coal  tar  disinfectant  (emulsifying  type),  and 
submitted  as  a basis  for  such  a standard,  a specification  adopted 
officially  by  the  Association  and  followed  by  a large  proportion  of  the 

The  Division  of  Trade  Standards  consulted  other  interested  indi- 
viduals and  organizations,  and  led  the  discussion  of  the  proposed  com- 
mercial standard  at  a convention  of  the  Association  in  New  York

Coal  Tar  Disinfectant 


Oity  on  December  6,  1937.  After  discussion,  the  convention  voted  to 
recommend  establishment  of  a commercial  standard  through  the  regu- 
lar procedure  of  the  National  Bureau  of  Standards. 

In  view  of  the  large  consumer  and  distributor  participation  during 
he  Association  convention  and  subsequent  review  of  the  proposed  com- 
nercial  standard  by  the  Federal  Food  and  Drug  Administration,  it 
appeared  that  the  purpose  of  a public  hearing  had  been  accomplished 
jmd  the  situation  did  not  warrant  the  calling  of  a general  conference 
or  further  consideration  of  the  specification. 

Accordingly,  on  March  23,  1938,  the  recommended  commercial 
standard  was  circulated  to  the  industry  for  written  acceptance  by 
Droducers,  distributors,  and  users.  Following  satisfactory  acceptance 
md  in  the  absence  of  active  opposition,  the  establishment  of  the  stand- 
ard was  announced  June  10,  1938. 


This  sheet  properly  filled  in,  signed,  and  returned  will  provide  for  the  recording 
of  your  organization  as  an  acceptor  of  this  commercial  standard.

Washington,  D.  C. 


Having  considered  the  statements  on  the  reverse  side  of  this  sheet, 
we  accept  the  Commercial  Standard  CS70-38  as  our  standard  of  prac- 
tice in  the 

Production 1 Distribution  1 Use  1 

of  coal  tar  disinfectant  (emulsifying  type). 

We  will  assist  in  securing  its  general  recognition  and  use,  and  will 
cooperate  with  the  standing  committee  to  effect  revisions  of  the 
standard  when  necessary. 

Signature  of  individual  officer 

(In  ink) 

(Kindly  typewrite  or  print  the  following  lines) 

Name  and  title  of  above  officer. 


(Fill  in  exactly  as  it  should  be  listed  in  pamphlet) 

Street  address 

City  and  State 

1 Please  designate  which  group  you  represent  by  drawing  lines  through  the  other  two.  Please  file  sepa- 
rate acceptances  for  all  subsidiary  companies  and  affiliates  which  should  be  listed  separately  as  acceptors. 
In  the  case  of  related  interests,  trade  papers,  colleges,  etc.,  desiring  to  record  their  general  approval,  the 
words  “in  principle”  should  be  added  after  the  signature. 



The  following  statements  answer  the  usual  questions  arising  in 
connection  with  the  acceptance  and  its  significance: 

1.  Enforcement. — Commercial  standards  are  commodity  specifica- 
tions voluntarily  established  by  mutual  consent  of  the  industry. 
They  present  a common  basis  of  understanding  between  the  pro- 
ducer, distributor,  and  consumer  and  should  not  be  confused  with 
any  plan  of  governmental  regulation  or  control.  The  United  States 
Department  of  Commerce  has  no  regulatory  power  in  the  enforce- 
ment of  their  provisions;  but,  since  they  represent  the  will  of  the 
industry  as  a whole,  their  provisions  through  usage  soon  become 
established  as  trade  customs,  and  are  made  effective  through  incor- 
poration into  sales  contracts  by  means  of  labels,  invoices,  and  the  like. 

2.  The  acceptor's  responsibility. — The  purpose  of  commercial  stand- 
ards is  to  establish  for  specific  commodities,  nationally  recognized 
grades  or  consumer  criteria,  and  the  benefits  therefrom  will  be  meas- 
urable in  direct  proportion  to  their  general  recognition  and  actual 
use.  Instances  will  occur  when  it  may  be  necessary  to  deviate  from 
the  standard  and  the  signing  of  an  acceptance  does  not  preclude 
such  departures;  however,  such  signature  indicates  an  intention  to 
follow  the  commercial  standard  where  practicable,  in  the  production, 
distribution,  or  consumption  of  the  article  in  question. 

3.  The  Department' s responsibility. — The  major  function  performed 
by  the  Department  of  Commerce  in  the  voluntary  establishment  of 
commercial  standards  on  a Nation-wide  basis  is  fourfold:  First,  to 
act  as  an  unbiased  coordinator  to  bring  all  branches  of  the  industry 
together  for  the  mutually  satisfactory  adjustment  of  trade  standards; 
second,  to  supply  such  assistance  and  advice  as  past  experience  with 
similar  programs  may  suggest;  third,  to  canvass  and  record  the 
extent  of  acceptance  and  adherence  to  the  standard  on  the  part  of 
producers,  distributors,  and  users;  and  fourth,  after  acceptance,  to 
publish  and  promulgate  the  standard  for  the  information  and  guid- 
ance of  buyers  and  sellers  of  the  commodity. 

4.  Announcement  and  promulgation. — When  the  standard  has  been 
endorsed  by  companies  representing  a satisfactory  majority  of  pro- 
duction, the  success  of  the  project  is  announced.  If,  however,  in 
the  opinion  of  the  standing  committee  of  the  industry  or  the  Depart- 
ment of  Commerce,  the  support  of  any  standard  is  inadequate,  the 
right  is  reserved  to  withhold  promulgation  and  publication. 





The  organizations  and  individuals  listed  below  have  accepted  this 
specification  as  their  standard  of  practice  in  the  production,  distribu- 
tion, and  use  of  emulsifying  type  coal  tar  disinfectant.  Such  endorse- 
ment does  not  signify  that  they  may  not  find  it  necessary  to  deviate 
from  the  standard,  nor  that  producers  so  listed  guarantee  all  of  their 
products  to  conform  with  the  requirements  of  this  standard.  There- 
fore specific  evidence  of  quality  certification  should  be  obtained  where
