3.53
standby
normally idle or idling piece of equipment that is capable of immediate automatic or manual start-up and continuous operation
3.54
thermal relief valve
valve for relieving pressure caused by thermal expansion of liquid within a closed volume
3.55
trip speed
rotational speed of the power-input rotor at which the independent emergency overspeed system operates to shut down a prime mover
NOTE For the purposes of this part of ISO 10440, the trip speed of alternating-current electric motors, except variable- frequency drives, is the speed corresponding to the synchronous speed of the motor at maximum supply frequency.
3.56
unit responsibility
responsibility for coordinating the technical aspects of the equipment and all auxiliary systems included in the scope of the order, including responsibility for reviewing such factors as the power requirements, speed, rotation, general arrangement, couplings, dynamics, noise, lubrication, sealing system, material test reports, instrumentation, piping, conformance to specifications and testing of components
3.57
vendor
supplier
agency that supplies the equipment
NOTE The vendor can be the manufacturer of the equipment or the manufacturer’s agent and normally is responsible for service support.
3.58
witnessed inspection witnessed test
inspection or test where the purchaser is notified of the timing of the inspection or test and a hold is placed on the inspection or test until the purchaser or his representative is in attendance
4 General
4.1 Pressure design code
The pressure design code shall be specified or agreed by the purchaser. Pressure components shall comply with
the pressure design code and the supplemental requirements in this part of ISO 10440.
4.2 Unit responsibility
The vendor who has unit responsibility shall ensure that all subvendors comply with the requirements of this part of ISO 10440.
4.3 Units of measurement
The purchaser shall specify whether data, drawings, hardware (including fasteners) and equipment supplied for this part of ISO 10440 shall use the SI or USC units.
NOTE Dedicated datasheets for SI units and for USC units are provided in Annex A.
5.1.13 Spare and replacement parts for the machine and all furnished auxiliaries shall meet all the criteria of this part of ISO 10440.
5.1.14 Oil reservoirs and housings that enclose moving, lubricated parts, such as bearings, shaft seals, highly polished parts, instruments and control elements, shall be designed to minimize contamination by moisture, dust and other foreign matter during periods of operation and idleness.
5.1.15 The equipment (machine, driver and ancillary equipment) shall perform on the test stand and on their permanent foundation within the specified acceptance criteria. After installation, the performance of the combined units shall be the joint responsibility of the purchaser and the vendor who has unit responsibility. The performance of the machine shall also take into account the following.
a) The power at the certified point shall not exceed 104 % of the quoted value with no negative tolerance on required capacity.
b) The compressor vendor shall confirm that the unit is capable of continuous operation at any specified conditions.
c) If specified, the compressor vendor shall confirm that the unit is capable of start-up at settle-out or elevated suction pressure.
d) The purchaser shall specify gas composition(s). The purchaser may also specify relative molecular mass, ratio of specific heats (CIC) and compressibility factor (Z).
e) Unless otherwise specified, the vendor shall use the specified values of flow, the specified gas composition and the gas conditions to calculate relative molecular mass, ratio of specific heats (C/C) and compressibility factor (Z). The compressor vendor shall indicate his values on the datasheets with the proposal and use them to calculate performance data.
5.1.16 If specified, the vendor shall review and comment on the purchaser’s piping and foundation drawings.
5.1.17 If specified, in order to verify compliance with agreed criteria (e.g. API RP 686 or vendor’s standard), the vendor’s representative shall witness
a) a check of the piping alignment performed by unfastening the major flanged connections of the equipment.
