Internationally recognized standards validate TESCO's commitment to quality, technical competence, and cybersecurity across its utility solutions portfolio.

BRISTOL, Pa., June 29, 2026 /PRNewswire/ -- TESCO Metering, a leading provider of metering equipment, meter testing solutions, field services, technical training, and Advanced Metering Infrastructure (AMI) solutions, today announced the continued maintenance of its enterprise-wide ISO 9001 and ISO/IEC 27001 certifications, along with its ISO 17025 laboratory accreditation.

Together, these internationally recognized standards demonstrate TESCO's commitment to delivering high-quality products and services, technically valid testing and calibration results, and a comprehensive, risk-based approach to information security that supports utility customers throughout North America and around the world.

As utilities modernize infrastructure, deploy Advanced Metering Infrastructure (AMI), strengthen cybersecurity programs, and manage increasingly complex regulatory requirements, the need for trusted partners has never been greater. TESCO's integrated management systems provide customers with confidence that products, services, testing activities, and information management processes are governed by rigorous international standards.

"Trust is earned through consistent performance, technical competence, and responsible stewardship of information," said Tom Lawton, President and CEO of TESCO Metering.

Protecting Information Through ISO/IEC 27001

As utilities continue to digitize operations, expand Advanced Metering Infrastructure (AMI), and deploy connected technologies, cybersecurity and data privacy have become mission-critical priorities.

TESCO maintains an Information Security Management System (ISMS) certified to ISO/IEC 27001, the globally recognized standard for information security management. The ISMS provides a comprehensive, risk-based framework that helps protect customer information, business information, and critical operational data through structured governance, documented processes, and continual improvement.

TESCO's ISMS is audited internally and externally by independent certification bodies and addresses people, processes, technology, and governance across the organization.

The system includes:

• Enterprise-wide information security controls
• Cybersecurity risk assessment and mitigation processes
• Data privacy protection measures
• Compliance with applicable legal, regulatory, and statutory requirements
• Executive management oversight and continual improvement activities

TESCO's current Statement of Applicability, dated January 6, 2026, includes all ISO/IEC 27001 Annex controls and reflects the organization's comprehensive approach to information security and cybersecurity risk management.

Ensuring Technical Competence Through ISO 17025

ISO 17025 is the international standard for testing and calibration laboratories and serves as the global benchmark for laboratory competence.

TESCO's ISO 17025 laboratory accreditation demonstrates that testing and calibration activities are performed using validated methods, controlled processes, qualified personnel, and traceable measurements that produce technically valid results.

• Equipment and procedures are regularly evaluated and maintained
• Results can be trusted for critical metering and utility applications

This accreditation reinforces TESCO's longstanding reputation as a trusted technical authority within the utility metering industry.

Delivering Operational Excellence Through ISO 9001

ISO 9001 is the world's most widely recognized quality management standard and establishes a framework for process consistency, customer focus, risk management, corrective action, and continual improvement.

TESCO's ISO 9001-certified Quality Management System helps ensure:

• Consistent product and service quality
• Strong process control and operational discipline
• Continuous improvement throughout the organization
