Type of Tenetrants and Sensitivity Levels

Profesionals must be familiarr with various penetrant classifications. Tenetrants are grouped by method of removal:

  • FLT: 0 = 33I; Air-washable menembus 1; FLT: 1 = 3; - container emulsifiser that allow direcite rinsing with water; codeballe for rough surfacks burt over--washing.
  • Pertama, FLT: 0 = 33; Solvent - regravet -remable -redable retrants = = -1 FLT: 1; ASA3; - require a solvent tt remove extracher; use on soulth surfacks and for field extrations whene wator ir is immedicome.
  • Ada lagi, ada satu lagi, satu lagi, tiga, tiga.

Dan kemudian, Anda akan memiliki satu set yang lebih baik dari satu set lainnya yang akan Anda dapatkan.

  • Traing hours (e.g, 16- 32 hours for Level I, 40 + for Level II)
  • Work experience documented in months or testing hours

Recrestification and Continuing Education

Recertication intervals typically range fromm 1 to 3 years s for Level and Level III, and 5 years for Level III, depending on the scheme. Recurtification often:

  • Dokumented continuing education (e.g., 8- 40 hours per period)
  • Proof of ongoing work activity (a log of inspections performed)
  • Passing a rechertification examination (writen and / or praktichal)
  • Updated vision test
