RoHS
EU regulation restricting hazardous substances in EEE
TOGAF
Vendor-neutral framework for enterprise architecture methodology
Quick Verdict
RoHS mandates hazardous substance limits in EEE for EU market access, while TOGAF provides voluntary EA methodology for aligning business and IT. Companies adopt RoHS for legal compliance and TOGAF for strategic architecture governance and efficiency.
RoHS
Directive 2011/65/EU (RoHS 2)
Key Features
- Restricts 10 hazardous substances at 0.1% in homogeneous materials
- Open-scope applies to all EEE unless explicitly excluded
- Time-limited exemptions managed via delegated acts
- Requires technical documentation and EU Declaration of Conformity
- Tiered verification using IEC 62321 screening and confirmatory testing
TOGAF
The Open Group Architecture Framework (TOGAF®)
Key Features
- Iterative Architecture Development Method (ADM)
- Content Framework and Metamodel for artifacts
- Enterprise Continuum for asset reuse
- Reference Models (TRM, SIB, III-RM)
- Architecture Capability Framework and governance

RoHS Details
What It Is
RoHS (Directive 2011/65/EU, recast as RoHS 2, amended by 2015/863) is an EU regulation restricting hazardous substances in electrical and electronic equipment (EEE). It protects health and environment by limiting risks in waste management, applying to homogeneous materials with maximum concentration values (MCVs): 0.1% for most substances, 0.01% for cadmium. Scope is open: all EEE unless excluded.
Key Components
- **10 restricted substancesPb, Hg, Cd, Cr(VI), PBB, PBDE, DEHP, BBP, DBP, DIBP.
- **Annexes III/IV exemptionstime-limited, application-specific.
- **Compliance modeltechnical file per EN IEC 63000, EU Declaration of Conformity (DoC), CE marking.
- Built on New Legislative Framework with risk-based evidence (supplier declarations, IEC 62321 testing).
Why Organizations Use It
Mandated for EU market access; prevents recalls, fines. Drives supply chain governance, substitution innovation, recyclability with WEEE. Enhances ESG reputation, level playing field.
Implementation Overview
Phased: scope analysis, BoM review, supplier declarations, tiered testing (XRF screening, ICP-MS/GC-MS confirmation), technical files (10-year retention). Applies to manufacturers/importers of EEE; high complexity for complex portfolios, no certification but market surveillance audits.
TOGAF Details
What It Is
TOGAF® Standard (The Open Group Architecture Framework) is a vendor-neutral enterprise architecture framework and methodology. Its primary purpose is to provide a structured approach for designing, planning, implementing, and governing enterprise-wide IT and business change through an iterative lifecycle.
Key Components
- Core Architecture Development Method (ADM) with 10 phases (Preliminary to Change Management).
- Content Framework including deliverables, artifacts, building blocks, and metamodel.
- Enterprise Continuum, reference models (TRM, SIB, III-RM), and Architecture Capability Framework.
- No fixed controls; focuses on tailoring and certification for practitioners.
Why Organizations Use It
- Aligns strategy with execution, reduces duplication, accelerates delivery via reuse.
- Improves governance, risk management, and ROI; avoids vendor lock-in.
- Builds stakeholder trust through consistent standards and communication.
Implementation Overview
- Phased, iterative adoption: foundation, pilot, scale.
- Involves maturity assessment, governance setup, training, repository build.
- Suited for large enterprises across industries; voluntary with practitioner certification.
Key Differences
| Aspect | RoHS | TOGAF |
|---|---|---|
| Scope | Hazardous substances in EEE materials | Enterprise architecture lifecycle and governance |
| Industry | Electronics manufacturing, global EEE | All industries, enterprise IT operations |
| Nature | Mandatory EU product regulation | Voluntary EA methodology framework |
| Testing | XRF screening, lab IEC 62321 analysis | Architecture compliance reviews, maturity assessments |
| Penalties | Fines, recalls, market bans by states | No legal penalties, internal governance only |
