1 Scope

GB/T 13917.6-2009 is the Chinese national standard on laboratory efficacy test methods and criterions of public health insecticides for pesticide registration - part 6: liquid vaporizer, in the field of agriculture. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 27 March 2009 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 October 2009. Classification: ICS 65.100, CCS B17. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This part of GB/T 13917 specifies the indoor medicinal efficacy measurement methods and evaluation criterion for liquid vaporizer. This part applies to the efficacy test methods and criterions of public health insecticides for pesticide registration of liquid vaporizer.

2 Test materials

Standard test insects of sensitive strains raised in the laboratory. Culex pipiens pallens (Northern region) or Culex pipiens quinquefasciatus (Southern region), female adults which did not suck blood on days 3 to 5 after emergence.

3 Instrument and equipment

3.1 Cylinder device (Figure 1) The colorless transparent cylinder (C) is supported on the bracket (I); there is a colorless transparent circular plate (E, F) above and below the cylinder. The circular plate (E) has a circular hole in the center and is plugged with a rubber plug (G). The circular plate (F) has a circular hole in the center and plugged with a rubber plug (H). The joint between the cylinder and the circular plate (E, F) is lined with rubber gaskets (D1, D2) to prevent leakage of chemicals. B - Glass square box, 700 mm in length, width and height; C - Small door, 100 mm wide and high; D - Big door; E - Bracket; F - Insect hole, 50 mm in diameter. Figure 2 -- Square box device
