ADR 2027 (accepted) — no change for UN 2015

ADR 2027 was accepted: depositary notification C.N.395.2026 (9 October 2026) records no objection to the amendments proposed by C.N.252.2026. It applies from 1 January 2027, and ADR 2025 may still be applied until 30 June 2027 (1.6.1.1). (C.N.395.2026)

ADR 2027: no Table A change for this entry (checked against ECE/TRANS/WP.15/274, Add.1 and Corr.1). Other parts of ADR 2027 may still affect its carriage.

ADR 2025 remains the edition FreightUtils serves and the one that applies until ADR 2027 takes effect on 1 January 2027; after that, ADR 2025 may still be applied until 30 June 2027 (1.6.1.1).

Labels
Labels: model 5.1 (Oxidizing substances), model 8 (Corrosive substances) (ADR 5.2.2.2.2, label model No. 5.1, 5.2.2.2.2, label model No. 8; paraphrase, not yet reviewed)
Packing
Packing instruction P501: Hydrogen peroxide UN 2015: inners of 5 l (125 kg outer) or 2 l bagged (50 kg 4G/1G), single and composite packagings; vented, filled to 90 %. Mixed packing provision MP2: No mixed packing: the goods must be alone in their package. (ADR 4.1.4.1, P501, 4.1.10.4, MP2; paraphrase, not yet reviewed)
Tanks
Portable tank instruction T9: Portable tank, Class 1 and 3–9: test 4 bar; shell 6 mm; relief Normal; bottom openings Not allowed. Portable tank provision TP2: Portable tank must not be filled beyond the degree of filling set by 4.2.1.9.3 (the 95-based formula). Portable tank provision TP6: Tank needs pressure-relief devices sized to its capacity and the substance so it cannot burst, even in a fire. Portable tank provision TP24: Tank may have an approved vapour-space device that vents slow-decomposition pressure but stops liquid leaking. Tank code L4DV(+): ADR tank code for Classes 1 and 3–9: liquid tank, 4 bar, openings D, valves/devices V, suffix (+). — L: tank for liquid-state substances (liquids, or solids handed over molten); 4: minimum calculation pressure of 4 bar (see 6.8.2.1.14); D: filled and discharged from the top; nothing opens below the liquid surface; V: has a 6.8.2.2.6 breather device but no flame-propagation protection, or is not explosion-pressure-shock resistant; (+): alternative use of the tank for other substances is allowed only where the certificate of type approval says so (3.2.1 column (12); 4.3.4.1.3) Tank provision TU3: Shell interior and every part touching the substance kept clean; no lubricant that could react dangerously with it on pumps or valves. Tank provision TU28: Tanks may be filled to no more than 95 % of capacity at a reference temperature of 15 °C. Tank provision TC2: Shells and equipment of aluminium at least 99.5 % pure or a steel that will not decompose hydrogen peroxide; aluminium walls capped at 15 mm. Tank provision TE8: Connections to the external pipe-sockets must be of materials that do not cause hydrogen peroxide to decompose. Tank provision TE9: A top-mounted shut-off device must stop pressure build-up from decomposition, liquid leakage and entry of foreign matter. Tank provision TT1: Pure aluminium tanks need initial and periodic hydraulic tests at only 250 kPa (2.5 bar) gauge. Vehicle for tank carriage: FL — Vehicle for flammable liquids (flash point ≤ 60 °C), flammable gases or UN 2015 > 60 % in tanks above set sizes.

Carriage
Carriage provision V5: These packages must not be carried in small containers. Loading provision CV24: Clean the vehicle or container of combustible debris before loading; no readily flammable stowage material. Operation provision S20: Chapter 8.4 supervision applies above 10 000 kg in packages, or above 3 000 litres in tanks. (ADR 7.2.4, V5, 7.5.11, CV24, 8.5, S20; paraphrase, not yet reviewed)
