This International Standard requires the identification of a pair of ICC profiles for each image: an image profile and a profile describing the reference printing system

and it is particularly important where there is an entrance to an assembly building from a shopping mall that the guidance given in BS 5588-10 is followed

BS IEC 62531 on property specification language is useful for:

Acoustics. Reference zero for the calibration of audiometric equipment - Reference equivalent threshold sound pressure levels for pure tones and insert earphones Ingestion-build-137917 This standard also provides recommendations1 Scope This part of ISO 389 specifies reference equivalent threshold sound pressure levels (RETSPL) for the calibration of pure tone audiometers supplementary to those specified in ISO 389: 19911). Values given in this part of ISO 389 are applicable to insert earphones of a pattern specified in clause 4. NOTE 1 For information, a note on the derivation of the reference values and the origin of the data input is given in annex A, and a bibliography is
