# Portable automatic data processing machines weighing not more than 10 kg

## 1. Scope and Applicability

This PCR applies to complete portable automatic data processing machines with a net equipment mass not exceeding 10 kg, including laptops, notebooks, sub-notebooks, ruggedized notebooks, mobile workstations, mobile thin clients, and two-in-one notebooks when the keyboard and display portions are supplied as one integrated finished product. It supports model-specific, product-family, plant-average, and production-weighted foreground data packages, but every package must represent complete market-ready equipment rather than a bare board or one component.

The PCR covers the cradle-to-grave product system: material and component supply; inbound transport; final assembly, firmware loading, testing, rejects, packaging and distribution; operation in all relevant power modes; maintenance, repair, reuse or refurbishment when modelled; and collection, dismantling, recovery and disposal. It does not prescribe a single bill of materials, manufacturing location, service life, duty cycle, or end-of-life rate. Those quantities are product-, site-, market-, and scenario-specific and must be collected and disclosed.

Standalone tablets or slates without an integrated physical keyboard, desktop computers, integrated desktops, computer systems, servers, telephones, standalone displays, and automatic-data-processing units classified outside the reviewed portable-machine boundary are excluded. Motherboards, printed circuit board assemblies, displays, batteries, chargers, keyboards, storage devices, chassis, and other parts or accessories are inputs to a complete machine, not substitutes for its reference product.

## 7. Allocation and Co-product Handling

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `allocation_avoid` | shared manufacturing, assembly, testing and logistics | Avoid allocation by subdividing processes and collecting configuration-, line-, batch- or route-specific records whenever practicable. | `environdec-pcr-2024-06` |
| `allocation_physical` | inseparable shared processes with a causal physical relationship | Use a physical basis such as mass, machine time or energy only when it reflects how inputs and outputs change and revenue per mass or energy is not materially different. | `environdec-pcr-2024-06` |
| `allocation_economic` | inseparable shared processes without a justified physical relationship | Use representative economic values at the unit-process exit and report a sensitivity analysis; do not use price merely because mass data are inconvenient. | `environdec-pcr-2024-06` |
| `allocation_rejects` | defective components and rejected finished machines | Assign consumed materials, component burdens, energy and waste treatment for rejects to conforming output; do not allocate them away as a separate saleable product unless a documented recovered output reaches substitution. | `environdec-pcr-2024-06` |
| `allocation_waste_substitution` | reuse, recycling and energy recovery | Apply the point-of-substitution boundary: assign all treatment before substitution to the waste-generating system and later processing to the subsequent system; when substitution is uncertain, conservatively retain treatment in the studied product system. | `environdec-pcr-2024-06` |
| `allocation_mass_conservation` | all allocated processes | The sum of allocated inputs and outputs shall equal the measured process totals, with no double counting or omission; disclose the basis and allocation factors. | `environdec-pcr-2024-06` |
