    ISO 16


    Welcome To Pacific Certifications!

    ISO 16:1975(EN) Acoustics — Standard tuning frequency (Standard musical pitch)

    This standard was published in the year 1975 by Technical Committee ISO/TC 43 Acoustics and was last reviewed in the year 2017
    ISO 16 specifies the frequency for note A in the treble stave and shall be 440 Hz. Tuning and retuning shall be effected by instruments producing it within an accuracy of 0,5 Hz.
    Technical Committee ISO/TC43 had reviewed ISO Recommendation R 16 and found it technically suitable for transformation. International Standard ISO 16, therefore, replaced ISO Recommendation R 16-1955 to which it is technically identical
    ISO Recommendation R 16 was approved by the Member Body countries like Austria, Netherlands, Sweden, Chile, New Zealand, Spain, Pakistan, Norway, United Kingdom, France, Ireland, etc
