 Foreword  
Uganda National Bureau of Standards (UNBS) is a parastatal under the Ministry of Trade , Industry and 
Cooperatives established under Cap 327 , of the Laws of Uganda , as amended .  UNBS is mandated to co -
ordinate the elaboration of standards and is  
(a) a member of International Organisation for Standardisation (ISO) and  
(b) a contact point for the WHO/FAO Codex Alimentarius Commission on Food Standards, and  
(c) the National Enquiry Point on TBT  Agreement  of the World Trade Organisation (WTO).  
The work of preparing Uganda Standards is carried out through Technical Committees. A Technical 
Committee is established to deliberate on standards in a given field or area and consists of key stakeholders 
including gover nment, academia, consumer groups, private sector and other interested parties.  
Draft Uganda Standards adopted by the Technical Committee are widely circulated to stakeholders and the 
general public for comments. The committee reviews the comments before r ecommending the draft standards 
for approval and declaration as Uganda Standards by the National Standards Council.  
The committee responsible for this document is Technical Committee UNBS /TC 5, [Chemicals and

 Disinfectants /sanitizers  — Specification  
1 Scope  
This draft Ugand a standard specifies  requirements, methods of sampling and test for disinfectants /sanitizers  
intended for  general use on inanimate  surfaces including  food contact and non -food contact surfaces.  This 
standard is applicable to disinfectants /sanitizers  represented for use on non -critical medical devices, 
environmental surfaces and other inanimate objects.  This standard do es not apply to  disinfectants /sanitizers  
containing  iodopho r(s) and aldehydes as  active ingredients . 
NOTE 1  Using this standard , it is not possib le to determine the bactericidal  activity of the undiluted product. Some 
dilution is always produced by the addition of inoculum, standard hard water and sterile skimmed milk. 
NOTE 2  If a product complies with the test requirements, it can be considered to be bactericidal, but it should not 
necessarily be inferred that the product is a suitable disinfectant /sanitizer  for a defined purpose.

When a purchaser requires ongoing verification of the quality of disinfect ants/sanitizers  for use on food 
contact surf aces , it is suggested that, instead of concentrating solely on eva luation of the final product, 
attention should  also be direct ed to the manufacturer's quality system. In this connection it should be noted 
that US ISO 9001 covers the provisions of an integ rated quality system.  
G.2 Quality system requirements  
G.2.1 When assessed in accordance with G .3, the quality system of a manufacturer of 
disinfect ants/sanitizers  for use on food contact surfaces  shall com ply with the requirements of G.2.2 to G.2.12. 
NOTE  Some or all of these requirements might be relaxed by the authority administering this standard if an 
appropriate source verification and inspection is being used by the manufacturer.  
G.2.2 Responsibility for the quality system shall be delegated to an off icer who has sufficient authority, 
and is sufficiently qualified, to ensure compliance with the relevant requirements of this standard.  
G.2.3 The responsibilities of all persons who have direct or indirect responsibility for quality shall be so 
defined and  documented as to ensure that there is no overlap of functions or responsibilities.  
G.2.4 Quality system documentation, and the amendment and revision of such documentation (including 
formulations, test methods and product standards), shall be written and authorized only by duly designated 
officers who have written authority to perform these functions.  
G.2.5 A documented quality system shall exist and be implemented to ensure that only 
disinfect ants/sanitizers  that comply with the relevant requirements of t his standard are delivered for use on 
food contact surfaces Such documentation shall include, but not be limited to:  
a) procedures for the manufacture of the respective products,  
b) standards for all the raw materials used,  
c) standards for the finished products,  
d) standards for the testing of raw materials, packaging, work in progress and finished products,  
e) standards for packaging, labelling and storage of the finished products, and  
f) systems to ensure that personnel involved in activities that affect the manufacture a nd quality of the 
disinfect ants/sanitizers  have available only current and suitably authorized documented procedures 
and standards, and that such documentation can be recalled and updated when necessary.  DUS 1693 :2017

 G.2.6 Systems shall exist and be implemented to ensu re that only raw materials and packaging that 
comply with the relevant requirements of this standard are used in the manufacture of disinfecta nts/sanitizers  
meant for food contact surfaces.  
G.2.7 The manufacturer shall implement a system of product identif ication to ensure that a product in its 
original packaging can be traced back to the relevant records of manufacture and sources of raw materials.  
G.2.8 Products shall be manufactured in appropriate premises, using appropriate equipment and in 
accordance w ith appropriate documented manufact uring procedures (see G .2.4), by appropriately trained 
employees. Process control procedures shall be such as to ensure a consistent quality of the end product.

body, together with sufficient safety data that cover both raw materials and the finished product, to satisfy the 
certification body with respect to the safety of the product when used in accordance with the ma nufacturer’s 
recommendations. Material safety data sheets shall form an integral part of such safety data. Formulations, 
once approved, shall not be altered without the approval of the certification body. The certification body shall 
impose such reappraisa l requirements as it considers necessary to ensure the continued safety of the 
product.  
G.2.10 Testing of raw materials, packaging, work in progress and finished product shall be carried out by 
appropriately qualified and trained personnel who have access to suitable equipment and facilities and in 
accordance with documented procedures. Test records shall be maintained and appropriate samples (see 
annex A) shall be retained for a period that is sufficient to comply with the requirements of the customer and 
the certification body or the regulatory or inspection authority.  
NOTE  A sample retention time of at least six months and a record retention time of at least two years are 
recommended.  
G.2.11 Test equipment shall be calib rated periodically to ensure  reliab ility and accuracy. Records of 
calibration shall be kept. The period between successive calibrations shall not exceed one year.  
G.2.12 Systems shall exist and be implemented to ensure that only disinfect ants/sanitizers  that comply 
with the relevant quality  standards are dispatched to the customer.  
G.3 Assessment of quality system
