Other automatic data processing machines whether or not containing in the same housing one or two of the following types of units: storage units, input units, output units

1. Scope and Applicability

This PCR applies to a specifically declared finished automatic data processing machine within the residual CPC 3.0 class 45250. The machine performs data processing and may contain, in the same housing, none, one, or two of these unit types: storage, input, and output. It is used only when the product is not more specifically covered by the neighbouring portable-machine, combined central-processing/input/output-machine, system, peripheral, storage-unit, other-unit, or parts subclasses.

Every foreground data package shall identify the concrete computing architecture; processor arrangement; housing form; the exact storage, input, and output units inside the housing; memory; expansion and accelerator configuration; power-supply and cooling design; firmware or operating environment; intended workload and use; included accessories; saleable configuration identifier; and net product mass. A record for one server, workstation, thin client, appliance, mainframe, embedded device, or other narrow configuration shall not be extrapolated to the whole CPC leaf. A production-weighted family dataset is allowed only when each included configuration is separately identified and weighted with audited production mass.

This PCR covers purchased components and subassemblies entering the declared manufacturing system, receiving and kitting, optional board mounting, system integration, firmware or software loading, configuration, testing, rework, final finishing, packaging, and producer-gate release. Upstream component production is represented by linked supplier datasets. Use, maintenance, refurbishment, and end-of-life are outside the default foreground boundary but shall be attached explicitly when a cradle-to-grave lifecycle model is produced.

Excluded products include portable automatic data processing machines of CPC 45220; machines of CPC 45230 containing at least a central processing unit and input and output units in the same housing; machines presented as systems under CPC 45240; separately supplied input/output units, storage units, other automatic data processing units, parts, and accessories; and products whose principal function belongs to telecommunications, consumer electronics, industrial control, or another more specific category. Classification is based on the product as supplied, not on a convenient server or embedded-computer proxy.

5. System Boundary

The default deliverable is a producer-gate foreground manufacturing data package. A downstream lifecyclemodel may extend it to raw-material acquisition, use, maintenance, refurbishment, and end-of-life, but shall keep the declared configuration and prevent overlap with linked component or treatment datasets.

Source limitation: ENERGY STAR Version 9.0 and ECMA-383 cover named computing product types and test conditions rather than the complete residual CPC 45250 leaf. They support configuration disclosure and conditional test-energy measurement only. No numerical value or single product architecture from either source is generalized across the category.
