Imagine you are building a house. You hire a structural engineer, and they hand you a stack of documents: IS 456 for concrete, IS 800 for steel, NBC 2016 for the national building code. You ask: "Which of these is law, and which is just a recommendation?" The answer is: the document itself is neither. A municipality gazette notification that references IS 456 is what makes it law. The standard is the technical rulebook. The regulation is the government order that says "you must follow this rulebook or you cannot sell here." Electronic product standards work exactly the same way — and confusing the two is how engineers waste months pursuing the wrong certification or miss a mandatory requirement entirely.

Standards vs Regulations — A Critical Distinction

A standard is a voluntary technical document produced by a standards body. IEC 62368-1 is a standard. CISPR 32 is a standard. On their own, they are recommendations. No government agency arrests you for violating them.

A regulation is a legal instrument — a law, directive, or statutory order — issued by a government authority. The EU's EMC Directive (2014/30/EU) is a regulation. India's BIS Compulsory Registration Scheme (CRS) notification is a regulation. These have legal force.

Regulations typically work by referencing standards. The EU EMC Directive says that products must meet "essential requirements" for electromagnetic compatibility. It then lists harmonised standards — EN 55032, EN 61000-3-2 — that, if followed, give a presumption of conformity with those essential requirements. You are not legally required to use the harmonised standard. You are legally required to meet the essential requirement. The harmonised standard is the proven path to proving you did.

The practical consequence: when an engineer says "we need to pass CE," they mean they need to demonstrate conformity with one or more EU directives by testing against the referenced harmonised standards. The directive is the law. The EN standard is the test method.

The Bodies That Write the Rules

How Indian IS Standards Relate to IEC

The Bureau of Indian Standards does not, in most cases, write electrical standards from scratch. BIS predominantly adopts IEC standards, sometimes with Indian modifications (additions for Indian grid voltage of 230 V / 50 Hz, local environmental conditions, or market-specific exemptions).

Key examples:

• IS 13252 → adoption of IEC 60950-1 (IT equipment safety). Required under BIS CRS for laptops, power adapters, printers, routers.
• IS 616 → adoption of IEC 60065 (audio/video equipment safety). Mandatory for televisions, set-top boxes, amplifiers under BIS CRS.
• IS 4772 → adoption of IEC 60335-1 (household appliance safety). Required for washing machines, fans, mixers.
• IS 302-2 series → adoption of IEC 60335-2 series for specific appliance subcategories.

The practical implication: if your product already complies with the parent IEC standard, BIS certification is largely a documentation and testing exercise through a BIS-recognized lab. The technical requirements are substantially the same. The pain is mostly administrative — getting a BIS license, maintaining it, and marking products correctly.

The Three EU Directives You Will Encounter Most

If you are selling into the EU or designing for EU customers, three directives cover the vast majority of embedded electronic products:

1. EMC Directive — 2014/30/EU
Covers electromagnetic compatibility. Your product must not emit interference that disrupts other equipment, and must have adequate immunity to interference from other equipment. Harmonised standards: EN 55032 (emissions for multimedia equipment), EN 61000-3-2 (harmonic current limits), EN 61000-3-3 (voltage fluctuations), EN 61000-4 series (immunity tests).

2. Low Voltage Directive (LVD) — 2014/35/EU
Covers electrical safety for equipment operating between 50 VAC–1000 VAC or 75 VDC–1500 VDC. Harmonised standard: EN 62368-1 (replaces EN 60950-1 for IT/AV equipment). If your product runs on mains or has mains-connected internal power supply, LVD applies.

3. Radio Equipment Directive (RED) — 2014/53/EU
Applies to any product with intentional radio transmission or reception — Wi-Fi, Bluetooth, LoRa, NB-IoT, Zigbee, anything with an antenna. RED covers safety, EMC, and radio spectrum use. If your product has any wireless interface, RED is the applicable directive and it supersedes the EMC Directive for that product.

Post-Brexit note: The UK UKCA marking replaced CE marking for the UK market from January 2023. UKCA uses UK-adopted versions of the same EU standards (prefixed "BS EN" instead of "EN"). A product with CE marking does not automatically qualify for UKCA. Products sold in both EU and UK need both marks unless covered by transitional arrangements.

The Standards Hierarchy

Voluntary vs Mandatory — How to Read the Landscape for Your Product

Use this decision logic when entering a new market:

1. Identify the market — India, EU, USA, UK, or other.
2. Identify the product category — IT equipment, industrial, medical, wireless, lighting.
3. Find the applicable regulations — BIS CRS notification (India), EU Directive (EU), FCC Rules (USA).
4. Find the referenced standards — the regulation points to specific standards.
5. Determine which standards are mandatory vs voluntary — mandatory if the regulation references them as harmonised standards or explicitly required by the regulatory body.
6. Check for exemptions — some categories (low-power battery-operated devices, certain industrial equipment) have reduced requirements or different limits.

A startup selling a LoRa-based industrial sensor in India needs: BIS CRS (IS 13252), WPC type approval for the LoRa radio module, and potentially IS 302 for the safety class. A startup selling the same product in the EU needs: RED (covers safety, EMC, and radio together), which references EN 62368-1, EN 55032, and the relevant radio interface standard.

Getting this mapping wrong before starting your certification program means testing against the wrong standards and discovering the gap when the certification lab hands back your test report.

The BIS Compulsory Registration Scheme — India's Mandatory Certification Path

For engineers building products for the Indian market, the BIS CRS (Compulsory Registration Scheme) is the most directly relevant regulatory framework. Under CRS, specific product categories cannot be legally sold in India without BIS registration. The list is maintained under the Electronics and Information Technology Goods (Requirements for Compulsory Registration) Order.

Products currently under BIS CRS (IT/electronics relevant):

• Laptops, notebooks, tablets, desktop computers
• Mobile phones and smartphones
• Power adapters and chargers (for IT equipment)
• LED lights, LED drivers, LED luminaires
• Wired and wireless keyboards, mice
• Printers, scanners, multifunction devices
• Set-top boxes, smart TVs
• UPS systems (up to certain power ratings)

The CRS registration process:

1. Sample testing — samples submitted to a BIS-recognized test laboratory (ERTL, STQC, or other BIS-approved labs). Testing performed against the referenced IS standard.
2. Application submission — test report, factory details, product details, and fees submitted to BIS online portal.
3. Grant of registration — BIS issues a registration number (R-XXXXXX format). This must appear on the product and its packaging.
4. Factory surveillance — BIS conducts periodic factory audits and market surveillance. Products must remain compliant; the registration is not a one-time clearance.
5. Renewal — registration must be renewed; BIS may require re-testing if the standard is revised.

Common startup mistake: ordering 500 units from a CM before BIS registration is granted. BIS registration takes 8–16 weeks. Units cannot be legally sold until registration is received. Planning the BIS registration timeline into the product launch schedule is not optional.

FCC Authorization — The USA Path

Products sold in the USA with any digital circuitry above 9 kHz must comply with FCC Part 15 (intentional and unintentional emitters) or Part 18 (ISM equipment). The FCC authorization process has three tracks:

Verification — lowest complexity. Used for Part 15 Class A digital devices (for use in commercial/industrial settings), TV interface devices, and others. Manufacturer self-certifies without submitting to FCC. Test records must be kept.

Declaration of Conformity (DoC) — used for Part 15 Class B digital devices intended for residential use. Manufacturer tests at an accredited lab and self-declares. No FCC submission required, but FCC ID not issued. A FCC Supplier's Declaration of Conformity (SDoC) label is required on the product.

Certification — required for intentional emitters (Wi-Fi, Bluetooth, cellular, LoRa). Product must be tested at an FCC-accredited Telecommunication Certification Body (TCB). FCC grants a unique FCC ID. The FCC ID must be displayed on the product (physically or in the electronic display). Module certification: if you use a pre-certified radio module (e.g., a certified Wi-Fi module from Espressif or u-blox), you may be able to use the module's existing FCC ID without re-testing the radio, subject to integration guidelines specified in the module's grant.

Key Takeaway

A standard is a technical rulebook. A regulation is the law that tells you which rulebook applies to your product in a given market. BIS IS standards are largely IEC standards with Indian modifications. The EU's CE marking is not a single test — it is conformity with one or more directives, each referencing multiple harmonised standards. Map your product to its markets and regulations before booking a single lab test. Every hour spent on the wrong standard is wasted.
