For calibration and testing laboratories
Bring controlled procedures, traceability chains, technical calculations and approvals into one connected record, from work at the bench to evidence in the audit room.
Supports evidence management within your quality system. Does not confer accreditation.
A controlled bench workflow
Confirm the equipment, applicable method revision and eligible reference standards.
Follow ordered procedure steps and capture readings, conditions and supporting evidence.
Apply the approved uncertainty budget and decision rule to the recorded result.
Route the complete technical record to authorised reviewers before release.
Method control at the point of work
Start with procedure identity, scope and readable ordered steps. Add advanced evidence, uncertainty and conformity controls only where the step requires them, then complete a pre-review check before independent approval.
Traceability with operating context
Treat reference standards as controlled assets with capability, range, calibration status, certificate evidence and restrictions. Record which standard was actually used so reviewers can follow the traceability chain from result to reference.
Technical reasoning, versioned
Preserve the controlled inputs used to evaluate a result, not only the final pass or fail.
CONTROLLED MEASUREMENT MODEL
Build reusable budgets from Type A and Type B components, distributions, divisors, sensitivity coefficients and coverage factors. Approved evidence retains the budget revision and per-point calculation used at the time.
CONTROLLED CONFORMITY MODEL
Connect measured error, tolerance, uncertainty, guard band and boundary policy to the conformity outcome. Reviewers can see which approved rule was applied rather than infer it later.
Review before release
Support separation of duties and scoped personnel authorisations without disconnecting approval from the evidence being reviewed.
Technicians complete the method and submit its connected evidence.
Authorised reviewers inspect results, references and calculations together.
Approval freezes relevant revisions and records the decision history.
Organisation and site isolation
Keep organisation-owned records within their authorised organisation context. Within it, site and location relationships provide the operating context for equipment, standards, work and evidence.
Roles and permissions are resolved for the selected organisation, helping multi-site teams collaborate without treating frontend filters as a security boundary.

One connected laboratory record
Audit evidence without reconstruction
Select internal or client sites and a reporting period, review the included evidence, then preserve that scope in a dossier revision without altering the underlying records.
Software support, not accreditation
Obsidian Metra supports controlled workflows and the management of ISO/IEC 17025-related evidence. It does not confer accreditation, certify conformity, guarantee compliance, or replace professional judgement. Your laboratory remains responsible for its methods, competence, decisions and quality system.
Build the record as the work happens
Start with an instrument, define its controlled work, and keep the evidence connected through technical approval and audit preparation.
