Technical consultation on specifications and quality control of netting materials and mosquito nets

Executive summary

Product specifications for mosquito netting materialwere developed by WHO in the year 2000. Five years on, this meeting was called to review the experiences of industry, major procurement agencies, quality testing labo- ratories and scientific experts with the 2000 specifications, and to adapt the specifications to the current market context including the development of new netting technologies.

The meeting agreed to replace the 2000 material-specific specifications for polyester, polyethylene and cotton netting, and instead to develop generic specifications applicable to all netting materials irrespective of the fibres from which they are made. The core characteristics of good quality nets are: prevention of insect/vector entry; dimensional stability after washing; strength of netting materials and seams; retention of strength over a period of time (durability and storage stability) and safety for users.

The meeting agreed on the need for guidelines for procurement of mosquito nets by national malaria control programmes and other net buyers, and developed an outline of such a document for finalization by the WHO Global Malaria Programme.

The attached report summarizes the issues discussed during the meeting, provides the updated specification for mosquito nets, and identifies important research needs related to the characteristics and quality of netting material.

In this report, the terms “netting” and “netting material” refer to the fabric, and the term “net” refers to the product made from netting/netting material, to be utilized as a vector barrier by the end-user.
