BS ISO 1217:2009+A1:2016

This International Standard specifies methods for acceptance tests regarding volume rate of flow and power requirements of displacement compressors. It also specifies methods for testing liquid-ring type compressors (see AnnexA). This International Standard specifies the operating and testing conditions which apply when a full performance test is specified. For compressors manufactured in batches or in continuous production quantities and supplied against specified data, the tests described in AnnexesB, C and D are considered equivalent alternatives. AnnexE, which is normative, applies to any electrically driven compressor manufactured in batches or in continuous production quantities and supplied against specified data having variable speed drive (e.g. variable frequency drive, direct current drive and switched reluctance), which incorporates a displacement compressor of any type driven by an electric motor. Detailed instructions are given for a full performance test, including the measurement of volume flow rate and power requirement, the correction of measured values to specified conditions and means of comparing the corrected values with the guarantee conditions. This International Standard specifies methods for determining the value of the tolerances to be applied to the measurement of flow, power and specific power. NOTE The tolerances to be applied to the measurement of flow, power, specific power, etc. for all acceptance tests carried out in accordance with this International Standard are agreed on by the manufacturer and the purchaser at the contractual stage or prior to the execution of the tests. AnnexF specifies standard inlet conditions for reference purposes. AnnexG, which is normative, indicates the uncertainty of measurement. This International Standard is not applicable to noise statements, which are identified in ISO2151 .
