 Foreword  
Develop ment of the E ast A frican Sta ndards has been necessitated by the need for harmonizing requirements 
governing quality of products and services in the East African Community. It is envisaged that through harmonized 
standardization, trade barrie rs that are enc ountered when  good s and serv ices are exchanged within the Commun ity 
will be removed.  
The Community has established an East African Standards Committee (EASC) mandated to develop and issue 
East African Standards (EAS) and other deliverables. The Committee is composed o f rep resentativ es of the 
National Standards Bodies in Partner States, tog ether with the representatives from the public and private sector 
organizations in the community.  
East African Standards are developed through Technical Committees that are represent ative  of key 
stakeholders including government, aca demia, consumer groups , private sector and other interested parties. 
Draft East African Standards are circulated to stakeholders through the National Standards Bodies in the Partner 
States. Th e comments re ceive d are disc ussed and incorporated before finali zation of standards, i n accordance 
with the Principles and procedures for development of East African Standards.  
East African Standards and other deliverables are subject to review, to keep p ace with tech nolog ical advan ces. 
Users of the East African Stand ards are therefore exp ected to ensure that they always have the latest versions 
of the standards they are implementing.  
The committee responsible for this document is Technical Committee EASC /TC 074, Surface a ctive agen ts 
Attention is drawn to the possibi lity that some of the elements of this document may be subject of patent rights. 
EAC shall not be held responsible for identifying any or all such patent rights.  
This second  edition cancels an d replaces th e first edition  (EAS 791:2013), which has been tech nically revised.

Samp ling 
C.1 Procedure  
C.1.1 In a single cons ignment, all packages (cartons) containing materials  drawn from the same batch of 
productio n shall constitute a lot. For ascertaining t he conformity of the lot to the requirements of this standard, 
tests shal l be ca rried out on each lot s eparately. The num ber of packages to be selected for drawing the sample 
shall be in accordance with Table C.1.  
Table C.1 — Scale of sampling  
Number of p ackages 
(cartons) in the lot  
N Number of packages (cartons) to 
be selecte d 
n Num ber of samples  
4 to 15 3 3 
16 to 40  4 4 
41 to 65  5 2 
66 to 110  7 2 
111 and above  10 1 
 
C.1.2 The packages shall be selected at  random, using tables of random numbers. If these are not available, 
the following procedure shall be applied:  
Starting fro m any package, count all the packages in one order as 1, 2, 3.... N, selecting every k th package, 
where k is the integral part of Nn.  
C.1.3 From each package thus selected, draw at random an equal number of containers  so as to obtain a 
total volume of at least 2 L.  
C.2 Samples for testing  
Take at one time all test sam ples required for the tests in 4.2. Measure  the test sample requi red for determination 
of free alkali or acid  content, and use it immediately.
