Ukuvikela: Irilayidi legesi, ivinile yokukhulula ingcindezi, ukuqapha i-chromatography kawoyela, i-thermometer.

III. Izici Zomkhiqizo
Ukonga amandla okulahleka okuphansi: Kuhambisana nezinga loku-1 lokonga amandla le-GB 20052-2020, uchungechunge lwe-S11/S13/S20. Ukulahleka okungenalutho kungu-15% - 25% ngaphansi kwejwayeza likazwelonke.
Amandla aqinile okulwa nokushintshana okufushane: Inhliziyo icindezelwe kakhulu, inezinsika eziqinile, futhi ukumiswa komile okucindezelwe konke kuyaguquguquka. Kudlula ukuhlolwa kokushintshana okufushane okungazelelwe.
Ukukhishwa okuncane kancane: Ukukhishwa kancane kancane kungaphansi noma kungalingani no-100 pC, futhi impilo yokuvikela imide.
Umsindo ophansi: Isakhiwo senhliziyo yensimbi esilungiselelwe, umsindo ≤ 60 dB (A).
