Introduction
Standards are everywhere in engineering and industry — from the bolts that hold an aircraft together to the safety codes behind a power plant. Yet, despite their importance, the process of finding, purchasing, and managing standards is often confusing, time-consuming, and costly.
This guide was created to simplify that journey. Whether you are an engineer searching for a single standard, or a procurement manager overseeing enterprise-wide access, you will find practical advice, comparisons, and checklists to help you make better decisions.
Who Should Read This Guide:
– Engineers and Specialists: Working in aerospace, defense, construction, or energy, often under time pressure to reference the “right version” of a standard during design.
– R&D Teams: Developing prototypes and needing to align early with industry requirements to avoid costly redesigns.
– Quality and Compliance Managers: Responsible for certifications like ISO 9001, AS9100, or API Q1, and ensuring all departments use the correct documents.
– Procurement and Library Managers: Managing limited budgets and balancing one-off purchases against enterprise subscriptions.
– Manufacturing and Operations Teams: Applying standards daily to production, testing, and maintenance processes.
The Challenge:
Standards are not like ordinary technical documents:
- They are constantly updated — sometimes multiple times a year.
- They are copyrighted works, not freely shareable like open guidelines.
- They exist in a fragmented ecosystem: thousands of SDOs, resellers, and databases.
Without a structured approach, companies risk:
– Using outdated versions in production.
– Duplicating purchases across departments.
– Failing compliance audits due to license misuse.
How to Use This Guide:
This is a handbook and a reference.
– Use it in a linear read if you’re new to standards management.
– Jump to specific sections (procurement, compliance, glossary) when solving a particular issue.
– Share it with colleagues to build a common knowledge base in your organization.
What Are Standards & Why Do They Matter?
Definition of Standards: A standard is a technical document that captures best practices, consensus knowledge, and agreed-upon requirements for a product, service, or process.
Standards are:
- The common language of trade — ensuring that a part manufactured in one country fits into an assembly in another.
- Developed by experts across industry, academia, regulators, and consumers.
- Living documents that evolve with new technologies, materials, and methods.
Why Standards Cost Money:
Standards Development Organizations (SDOs) operate differently from government regulators.
– They rely on sales revenue (not taxes) to fund expert committees, technical research, and publishing infrastructure.
– Every purchase supports the maintenance and revision process, which can involve hundreds of hours of expert volunteer work.
– Without standard sales, SDOs would need to find alternative revenue streams to be able to update standards to keep pace with innovation.
Did You Know?
– Babylon (2000 BCE): Grain measurements and building units were standardized.
– Rome (100 CE): Roads, aqueducts, and military tools were built to standard dimensions.
– 18th–19th Century: The metric system and modern metrology created the basis for industrial trade.
– 20th Century: Formation of ISO, IEC, ASTM, SAE, and ASME enabled global harmonization.
Standards are not just modern bureaucracy — they are the continuation of a 4,000-year tradition of making human activity safer, more efficient, and more compatible.
Benefits of Standards at Different Levels:
– For Engineers: Reduce trial-and-error in design; provide reliable references; improve collaboration across teams and suppliers.
– For Companies: Improve product quality and efficiency; reduce risks and rework; open access to international markets.
– For Consumers: Safer, more reliable products; ability to compare quality across brands; greater trust in what they buy.
– For the Economy: Boosts competitiveness and innovation; facilitates trade across borders; reduces waste and inefficiencies.
The 8 Key Benefits to Businesses:
- Quality Improvement – Standardized requirements reduce defects.
- Safety & Reliability – Protect workers, consumers, and infrastructure.
- Efficiency Gains – Lower waste, faster workflows.
- Market Access & Trade – Easier compliance with international requirements.
- Innovation Support – Build on existing knowledge to innovate faster.
- Compliance & Risk Management – Meet regulations, avoid fines.
- Customer Trust – Standards are proof of professionalism and credibility.
- Cost Optimization – Reduce recalls, downtime, and duplication.
Who Develops Standards? – SDOs & Committees
The Ecosystem of Standardization:
A single global authority does not create standards. Instead, they are developed by a network of organizations at the international, regional, and national levels. These bodies are known as Standards Development Organizations (SDOs).
– International SDOs (e.g., ISO, IEC, ASTM, SAE, ASME, IEEE, API) create documents accepted across countries.
– Regional SDOs (e.g., CEN, CENELEC, ETSI) harmonize standards within a specific region, such as Europe.
– National SDOs (e.g., ANSI in the U.S., BSI in the U.K., DIN in Germany, TSE in Turkey) publish and adopt standards tailored to their country.
Together, these organizations maintain a shared framework that ensures consistency worldwide, while allowing for local adaptation.
International SDOs:
- ISO (International Organization for Standardization): Covers almost every sector, from quality (ISO 9001) to sustainability (ISO 14001).
- IEC (International Electrotechnical Commission): Focused on electrical, electronic, and related technologies.
- ASTM International: Leading provider of materials, testing, and industrial standards.
- SAE International: Specializes in aerospace and automotive standards.
- ASME (American Society of Mechanical Engineers): Known for the Boiler & Pressure Vessel Code and mechanical design standards.
- IEEE (Institute of Electrical and Electronics Engineers): Focused on electrical, IT, and telecommunications.
- API (American Petroleum Institute): Oil, gas, and petrochemicals.
Regional SDOs:
- CEN (European Committee for Standardization): Non-electrotechnical standards for Europe.
- CENELEC (European Committee for Electrotechnical Standardization): Electrical engineering and safety.
- ETSI (European Telecommunications Standards Institute): Telecommunications and ICT.
National SDOs:
- ANSI (American National Standards Institute) – coordinates U.S. standards.
- BSI (British Standards Institution) – one of the oldest standards organizations.
- DIN (German Institute for Standardization) – strong in engineering and manufacturing.
- TSE (Turkish Standards Institution) – adapts ISO/IEC/CEN standards and publishes national standards.
Mini Reference Table (Sample):

| TSE | Turkish Standards Institution | National standards + ISO/IEC adoption | National | TS EN ISO 9001 |
Mirror Committees:
Countries don’t just adopt standards — they also participate in shaping them. Mirror committees are national groups that reflect the work of international technical committees.
– Track the work of ISO/IEC or CEN/CENELEC committees.
– Consolidate the national position and feed it back to the global process.
– Allow local experts to directly influence draft standards.
Example: TSE Ayna Komiteler in Turkey bring together experts from industry, government, and universities to review drafts before feedback is sent to ISO/IEC.
This ensures that global standards are not just imposed — they are shaped by national voices.

Adoption Models:
When an international or regional standard is published, countries can adopt it into their national catalog. This can happen in different ways:
– IDT (Identical): Adopted without any changes.
– MOD (Modified): Minor modifications added for national needs.
– NEQ (Not Equivalent): Substantial differences from the international standard.
For engineers, the adoption model matters — you must confirm whether the national standard you use is fully aligned with its international version.
Why Participation Matters
– Companies that join mirror committees gain early insight into upcoming requirements.
– They can influence standards before they are finalized.
– Participation allows know-how transfer between local experts and global leaders.
