STANDARDS KNOWLEDGE BASE

Standards and certification knowledge

Open a standard for its definition, scope, core requirements, typical route and common mistakes. Final applicability, edition and conformity route are confirmed against the product and target market.

REACHWhat is REACH?Open detailed explanation

What it is

REACH is the EU regulation on the registration, evaluation, authorisation and restriction of chemicals. For finished articles, compliance is not one universal test: the material, substance, concentration, use and supply-chain duties determine the required evidence.

Where it applies

It can affect substances, mixtures and articles placed on the EU/EEA market, including textiles, footwear, toys, electronics, plastics, coatings, metals and packaging. The test matrix must follow material and exposure risk.

Core requirements

  • Annex XVII restrictions set bans, limits or conditions for specific substances, products and uses
  • Candidate List SVHCs can trigger supply-chain communication, consumer-response and other notification duties
  • BOMs, declarations, supplier evidence and risk-based testing should be connected rather than replaced by one generic report

Typical route

  1. 01

    Break down materials and accessible components

  2. 02

    Map restrictions and SVHC risks

  3. 03

    Define individual/composite tests and reporting limits

  4. 04

    Review results, declarations and supply-chain records

Common mistakes

  • “REACH passed” is not a permanent conclusion for every product and substance
  • Lists change; a material, supplier or formulation change may require reassessment
RoHSWhat is RoHS?Open detailed explanation

What it is

RoHS restricts specified hazardous substances in electrical and electronic equipment. Compliance is generally assessed at homogeneous-material level, not only as a whole-product average. Most restricted substances use a 0.1% limit and cadmium generally 0.01%, subject to scope and exemptions.

Where it applies

Applies to electrical and electronic equipment within the directive and its cables, solder, plastics, coatings and other homogeneous materials. Batteries and packaging can be governed by separate rules.

Core requirements

  • Confirm product scope and any exemption before testing
  • Use the BOM and material risk to select lead, cadmium, mercury, hexavalent chromium, flame-retardant and phthalate tests
  • Technical evidence should link results and declarations to specific parts

Typical route

  1. 01

    Build the homogeneous-material list

  2. 02

    Screen high-risk parts and supplier files

  3. 03

    Use XRF screening or confirmatory chemistry as appropriate

  4. 04

    Compile the RoHS evidence pack and control changes

Common mistakes

  • One whole-product test does not automatically cover model differences or later material changes
  • A RoHS report does not replace safety, EMC or other CE technical-file duties
CPSIAWhat is CPSIA?Open detailed explanation

What it is

CPSIA is the US Consumer Product Safety Improvement Act. It strengthened requirements for lead, phthalates, toy safety, tracking labels, third-party testing and certificates for children’s products, generally those designed or intended primarily for children 12 or younger.

Where it applies

Applies to children’s products governed by CPSC rules, such as toys, apparel, childcare articles, furniture and durable infant products. Product-specific 16 CFR rules may also apply.

Core requirements

  • Applicable children’s rules generally require testing by a CPSC-accepted third-party laboratory
  • The US manufacturer or importer issues the CPC based on compliant testing
  • Product and package tracking labels should align with production and test records

Typical route

  1. 01

    Confirm age grading and children’s-product status

  2. 02

    List every applicable CPSC rule

  3. 03

    Test representative samples at an accepted lab

  4. 04

    Issue the CPC and manage material-change and periodic-test records

Common mistakes

  • The laboratory issues test results; the US manufacturer or importer normally issues the CPC
  • A generic “CPSIA test” can omit product-specific mandatory rules
California Proposition 65What is California Proposition 65?Open detailed explanation

What it is

California Proposition 65 requires a clear and reasonable warning when a business causes exposure to a listed carcinogen or reproductive toxicant above an applicable safe-harbour level. It is not one universal product test or certification.

Where it applies

Applies to products sold in California or exposing California consumers. Lead, cadmium, phthalates, nickel and formaldehyde are common concerns, but warning duties depend on the chemical and exposure assessment.

Core requirements

  • Identify listed chemicals and high-risk materials first
  • A concentration result is not automatically an exposure assessment
  • Warning wording, placement and online display need current-rule review

Typical route

  1. 01

    Screen materials and supplier declarations

  2. 02

    Define analytical tests and exposure assessment

  3. 03

    Choose reformulation, substitution or warning

  4. 04

    Retain the decision basis and monitor list updates

Common mistakes

  • “Not detected” depends on method and reporting limit and must be read with exposure context
  • A warning does not mean government certification that the product is safe or unsafe

AI SUPPORT

Turn the report into next steps

AI helps organise and explain; professionals confirm field facts and formal conclusions.

Read the complete explanation

AI prepares a test-scope draft from product, market and material inputs. Any regulatory uncertainty is escalated for technical review.

Human accountability

AI does not change field facts, decide the final verdict or replace professional approval.

FAQ

Frequently asked questions

Can I request service with incomplete information?

Yes. Share the product, market, date and risks you know. The service manager will identify gaps; unconfirmed information is never converted into a field fact.

Does AI issue the final conclusion?

No. AI organises files, finds contradictions and flags missing evidence. Relevant professionals own field facts and final technical decisions.

When will the plan be confirmed?

Normally within one business day after sufficient information is available. Testing and certification timing depends on the exact project.

Tell us the product and target market. The right workflow will take it from there.
