Technical consultation on specifications and quality control of netting materials and mosquito nets
5. GUIDELINES FOR PROCUREMENT AND QUALITY INSPECTION OF MOSQUITO NETS
Outline of content
Consensus was reached on the following outline for the content of Guidelines for procurement and quality inspection, which should be further elaborated, for use by national programme managers and other unaccustomed purchasers who do not benefit from the services of well-established procurement agencies. The guidelines should reference simple but well- proven testing methods, to minimize time and cost while providing reliable results. Following these guidelines and the WHO specification, purchasing authorities should be able to adequately manage the procurement, quality control and interpret test results.
5.1 Netting material
The fabric must comply with the WHO specification for mosquito nets. Some additional, application-specific, requirements may be defined by the supplier (e.g. number of filaments, type of fabric, weight). Nets for protection against other vectors may require specifications which are different from those adopted for mosquito nets.
5.2 Physical attributes of the nets
The product must comply with WHO specifications for mosquito nets. Net design and performance indicators should be specified, e.g. shape, size, colour, etc., according to local habits or the requirements of the application.
5.3 Reference samples
Bids for supply of nets must be accompanied by a reference sample of the nets which will be supplied. This reference sample must be comprised of at least two nets, one to be tested by the purchaser and one to be stored as a reference in case of disputes. Producers must deliver a uniform consignment which conforms to the reference sample.
