directiva CE 2000/14/CE.

Nota 2: el nivel de presión sonora equivalente, según la norma ISO 22868, se calcula

como la suma de energÌa, ponderada en el tiempo, de los niveles de presión sonora en

diferentes condiciones de trabajo. La dispersión estadÌstica habitual del nivel de presión

sonora equivalente es la desviación tÌpica de 1 dB(A).

Nota 3: el nivel de vibración equivalente, según la norma ISO 22867, se calcula como la

suma de energÌa, ponderada en el tiempo, de los niveles de vibración en diferentes condi-

ciones de trabajo. Los datos referidos del nivel de vibración equivalente poseen una disper-

sión estadÌstica habitual (desviación tÌpica) de 1 m/s
