n Devices  Wavelength test  equipment  Equipment has a wavelength  measuring device (a wavemeter (a  spectrometer when the laser beam  type is a pulsed beam) with a  measurement accuracy of 1 nanometer  or more, and being capable of  measuring a wavelength of 400  nanometers or more and up to 700  nanometers).  Optical power test  equipment  Equipment has an optical power meter  (being capable of measuring a  wavelength of 400 nanometers or more  and up to 700 nanometers, and with a  measurement accuracy of 10  nanowatts or more, and being capable  of measuring up to 10 milliwatts;  provided, however, that when the  laser beam type is a pulsed beam, the  meter has a sensitivity equivalent to  the pulse frequency).  3.  Bathwate r  Circulator s  Tension test equipment  Tension testing machine (being  capable of retaining or recording the  measured maximum value, and with a  scale accuracy of 0.1 newtons or more,  and being capable of measuring up to  30 newtons) and hair (human hair of  50 grams and 180 grams attached to a  wooden stick with a diameter of 25  millimeters and a length of 300  millimeters, with the length of the  part of the hair that is not attached to  the stick being 400 millimeters).  4.  Lighters  Flame generating  operation force and  flame adjusting  operation force  measuring equipment  Equipment has a load testing device  (with a measurement accuracy of full  scale +/- 0.2 percent or less, and being  capable of measuring up to 100  newtons).  Flame height measuring  equipment  Equipment has a measuring stand (a  vertically standing noncombustible  board horizontally scaled with 5  millimeter intervals and a device that  is unaffected by wind, made from a  noncombustible material).  53
