Notification
 IS 7142 small welded cylinders are regulated under the Gas Cylinders Rules, 2016, notified via GSR 1081(E) dated 22 November 2016 (which superseded the 2004 Rules). The 2016 Rules were published from draft GSR 779(E) dated 13 October 2015 and have been subject to later updates (e.g., Gas Cylinders Amendment Rules, 2022).
Enforcement Timeline
 The Gas Cylinders Rules, 2016 took effect on 22 November 2016; from that date PESO licensing, approvals and IS conformity obligations apply to manufacture, filling, import and sale.
Overview
 IS 7142 covers welded low carbon steel cylinders not exceeding 5 L water capacity intended for low-pressure liquefiable gases. GCR 2016 provides operational controls (valve standards, markings, colour coding, testing periodicity and licence requirements) which apply to these cylinders.
Objective & Scope
 To ensure safe manufacture, filling and use of small welded cylinders: standardised design and materials, approved valve fittings, mandated marking and identification, mandatory periodic examination and hydrostatic testing, and PESO licencing for relevant activities.
Products Covered
Welded low carbon steel cylinders with water capacity ≤ 5 litres for low-pressure liquefiable gases (other small gas cylinder types may reference IS 8776/IS 8737 for LPG where applicable).
Exemptions Provided
 No product-specific exemption is provided for IS 7142 cylinders. General exemptions under Rule 44 (small-quantity possession without licence or dealer’s sales room thresholds) may apply, subject to the Rule’s conditions.
Industries Impacted
 Cylinder manufacturers (small cylinder lines), valve/regulator makers, refrigerant & specialty gas producers, medical/industrial gas suppliers, importers, distributors, testing stations and PESO licensing authorities.
Mandatory Compliance Requirements
 Manufacture and use must follow IS 7142 (Scheme-I ) and the Gas Cylinders Rules: valve and regulator specifications per Rule 4, markings as per Rule 6, identification colours Rule 8, periodic hydrostatic/hydrostatic-stretch testing per Rule 35/Schedule IV (IS:15975), and compliance with filling/filling-ratio rules where relevant. PESO approval for manufacture/filling/import is mandatory in most commercial scenarios.
Next Steps for Stakeholders
- Prepare PESO application (Forms B/C/D/E/F as applicable) with required documents (plant layout, SOPs, ISO certificates, testing proposals).
- Align manufacturing drawings and test procedures to IS 7142 (Scheme-I ) and Schedule IV; engage a PESO-recognised inspecting authority.
- Set up or contract PESO-approved testing station for periodic hydrostatic tests and requalification; implement stamping/traceability and colour coding.
Legal Provisions, Enforcement & Penalties
The Gas Cylinders Rules, 2016 are enforced under the Explosives Act, 1884, with PESO as the licensing and enforcement authority. Penalties for violations include seizure of non-conforming valves, cancellation of licences, monetary fines, and imprisonment.
Conclusion
 IS 7142 welded small cylinders (≤5 L) are covered by the Gas Cylinders Rules, 2016. Stakeholders must ensure IS conformity, PESO approvals, correct valve selection, mandated markings/colour codes, periodical testing and compliance with licence conditions for lawful manufacture, filling, import and distribution.
