Calibration Compliance
Documentation & Audit Readiness
Cambri Compliance helps pipeline operators, utilities, and contractors build and maintain audit-ready calibration documentation systems — including recordkeeping structure, traceability reviews, interval documentation, certificate management, and audit readiness preparation.
Scope note: Cambri supports calibration compliance documentation, recordkeeping systems, traceability, and audit readiness. We review programs, intervals, records, and documentation practices — complementing your calibration software or existing processes.

Program Review
Identify gaps before an inspection occurs
Calibration Compliance Support Services
Documentation, recordkeeping, traceability, interval review, and audit readiness — from program structure to record retrieval.
Calibration Program Review
We conduct a systematic review of your existing calibration program — covering covered instruments, calibration intervals, documentation requirements, recordkeeping practices, and compliance with applicable regulations and standards.
Calibration Interval Review
We evaluate whether calibration intervals are appropriate for each instrument class and consistent with regulatory requirements, manufacturer specifications, and internal risk tolerance — and whether interval decisions are documented and defensible.
Documentation & Recordkeeping Review
We review your calibration records for completeness — verifying that every required field is present, including instrument ID, calibration date, calibration standard used, result (as-found / as-left), and technician information.
Traceability & Certificate Documentation Review
We evaluate whether your calibration records establish a clear traceability chain from each instrument through its calibration standard, certificate of calibration, and NIST traceability — as required for audit and regulatory review.
Audit Readiness Preparation
We prepare your calibration documentation for inspection — identifying what an auditor is likely to request, testing retrieval speed and completeness, and surfacing records that cannot be produced quickly or fully from your current system.
Calibration Compliance Program Structure Review
We assess your written calibration program documentation against applicable PHMSA and regulatory requirements — identifying where the program document, covered instrument list, or administrative controls need to be updated or strengthened.
Out-of-Tolerance & Recall Documentation Review
We review your procedures and records for handling out-of-tolerance findings, including impact assessment processes, affected measurement records, corrective action documentation, and recall workflows for previously calibrated instruments.
Calibration Record Organization & System Setup
We help organizations design and implement a centralized calibration recordkeeping structure — defining how records are organized, indexed, retained, and made retrievable during inspections and audits.

- Calibration recordkeeping — completeness, organization, and retention practices
- Traceability review — instrument → standard → certificate → NIST chain
- Calibration interval review — appropriateness, consistency, and documentation
- Audit readiness — documentation review, retrieval testing, gap identification
- Out-of-tolerance and recall documentation process review
- Calibration compliance program structure under applicable PHMSA regulations
- Calibration record organization and centralized recordkeeping system setup
Cambri Does NOT Provide
- Hands-on calibration services or instrument calibration
- Calibration technician training or instruction
- On-site instrument measurement or adjustment
- Calibration laboratory services
