Hand tools (including hand tools of a kind used in agriculture, horticulture or forestry, hand saws, files, pliers and metal cutting shears, hand-operated spanners, blow-lamps and clamps)

1. Scope and Applicability

This PCR applies to manually operated hand tools within the semantic boundary of CPC 3.0 subclass 42921, including agricultural, horticultural and forestry hand tools, hand saws, files, pliers, pincers, metal-cutting shears, hand-operated spanners and wrenches, blow-lamps, vices, clamps and comparable non-powered hand tools. It supports foreground production datasets from received materials and purchased components through forming or machining, route-specific heat treatment and surface finishing, final assembly, inspection and packaging at the factory gate.

The PCR excludes powered hand tools, interchangeable tool inserts and dies, machine knives, tool holders and machine-tool accessories, cutlery, scissors and knives classified outside CPC 42921, manufacturing or trade services, distribution, use, maintenance, sharpening, and end-of-life. A study may add excluded life-cycle stages, but it shall report them separately from this default factory-gate boundary.

Because this subclass contains products with different functions and routes, the data package shall identify one product model or a declared, production-weighted product group. Route-conditioned processes and flows are included only when they occur for that declared product or group.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_subdivision_first	shared equipment and multifunctional processes	Avoid allocation where practicable by submetering, production-order records, machine time, bath throughput or another subdivision that directly attributes inputs and outputs to the declared hand-tool product.	eu-commission-environmental-footprint-2021
allocation_physical_relation	residual shared burdens after subdivision	If subdivision is not practicable, use a documented causal physical relationship such as machine time, treated mass, bath throughput or occupied furnace capacity. Demonstrate why the relationship represents resource use or emissions.	eu-commission-environmental-footprint-2021
allocation_other_relation	multifunctional processes without a defensible physical relation	Use another relationship, including economic allocation only as a last step, and document why subdivision, system expansion and physical allocation were rejected, the prices and period used, and the sensitivity of results.	eu-commission-environmental-footprint-2021
allocation_scrap_and_rework	internal rework and outgoing steel scrap	Keep internal rework inside the foreground mass balance without treating it as a co-product. Record outgoing scrap quantity and destination separately; any recycling credit or burden belongs to the declared study method and shall not be embedded silently in the foreground amount.	eu-commission-environmental-footprint-2021

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
calculation_normalization	all inventory rows	normalized amount = period amount attributable to the declared product ÷ net conforming product mass for the same period	attributable row amount; net conforming finished-hand-tool mass	row amount per 1 kg net finished hand tools
calculation_electricity_conversion	electricity recorded in kWh	electricity (MJ) = metered electricity (kWh) × 3.6 MJ/kWh	metered kWh	MJ electricity
calculation_volume_to_mass	process water or wastewater measured by volume	mass = measured volume × measured or declared density at the recorded conditions	volume; density; temperature where relevant	kg water or wastewater
calculation_direct_fossil_co2	on-site natural-gas combustion where direct measurement is unavailable	calculate fossil CO2 from collected fuel quantity, fuel-specific carbon content, fossil fraction and oxidation fraction; retain all input records and units	metered gas; reference conditions; carbon content; fossil fraction; oxidation fraction	kg direct fossil CO2
calculation_product_group_weighting	datasets covering more than one hand-tool model	aggregate each model's attributable inventory using actual net production mass for the data period; do not use an unweighted average	model-level inventory; model-level net production mass	production-mass-weighted product-group inventory

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_identity	reference product and all product inputs	Verify product model, CPC boundary, material or chemical identity, supplied state and UUID semantics; do not reuse a UUID for a different concentration, stock form, polymer, waste or product state.	product specification, supplier documentation, direct-read identity audit and bill of materials
dq_temporal	all foreground records	Use a common representative period, normally 12 consecutive months; explain shorter campaigns, abnormal downtime and seasonal or product-mix effects.	dated meters, production orders, invoices and representativeness statement
dq_completeness	each included process	Reconcile material inputs, internal transfers, net product, scrap, wastewater and other wastes. Add every unlisted actual material, energy, waste or direct emission as one concrete atomic exchange.	process mass balance, route checklist, waste manifests and reconciliation record
dq_measurement	measured and converted amounts	Use calibrated instruments or documented supplier records and retain original units, conversions, allocation drivers and uncertainty or data-gap notes.	calibration certificates, invoices, meter logs and calculation workbook
dq_geography_technology	foreground and upstream datasets	Match the manufacturing geography, grid, fuel supply, material technology and treatment route as closely as available; disclose material mismatches.	dataset metadata and representativeness assessment
dq_route_condition	conditional processes and flows	Demonstrate applicability or non-applicability from the declared bill of materials, process route and site records.	routing sheet, process flow diagram, work instructions and product specification

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validation_reference_flow	reference product	Confirm that the output is exactly 1 kg net conforming finished hand tools, the reference UUID is unchanged, packaging is excluded from net mass, and all required qualifiers are present.	un-cpc-3-0-structure-2025
validation_process_route	process map and inventory	Every process that occurs for the declared product shall have a matching inventory section and records; every conditional process omitted shall have documented non-applicability.	us-epa-metal-products-machinery-2003
validation_atomic_flows	inventory exchanges	Confirm that every row denotes one physical, chemical, waste, energy or elementary exchange. Reject collection labels, combined utilities, unspecified packaging, combined wastes and umbrella emissions.
validation_mass_balance	each foreground process and aggregated system	Reconcile input mass, internal transfers, conforming output, rejects, scrap, wastewater and inventory changes; investigate and disclose unexplained imbalance rather than forcing closure.	us-epa-fabricated-metal-products-1995
validation_energy_boundary	electricity, natural gas and direct carbon dioxide	Confirm units and reference conditions, prevent double counting between shared meters, and include only direct on-site fossil CO2 in the elementary-flow row.
validation_chemical_state	sodium hydroxide and hydrochloric acid	Confirm as-supplied mass and concentration. The hydrochloric-acid UUID in this PCR is valid only for the explicit 32% solution row.
validation_unresolved_identity	UUID-empty rows	Treat the metal-finishing wastewater and hardwood-handle UUIDs as unresolved; do not substitute evaporation condensate, rough wood, pallets or another proxy.
validation_source_and_allocation	evidence and shared burdens	Confirm source references, collection records, allocation hierarchy, drivers and sensitivity disclosures.	eu-commission-environmental-footprint-2021
