The following tests are required:
●Drop Test (see 6.1.9.2.1);
●Hydraulic Pressure Test (see 6.1.9.2.2);
●Bursting Test (see 6.1.9.2.3);
●Leakage Test (see 6.1.9.2.4).
6.1.9.2.1 Drop Test
The Drop Test must consist of:
(a)  Method of testing—to ensure that creep does not affect the ability of the receptacle type to retain the contents, the receptacles must be dropped as follows:
●  three groups of twenty-five filled receptacles must be dropped from 1.8 m on to a rigid, non-resilient, flat and horizontal surface;
●  one group must be conditioned at 38°C for 26 weeks, the second group for 100 hours at
50°C; and
●  the third group for 18 hours at 55°C, prior to the
drop test.
(b) Criteria for passing the test successfully—the recep-6.1 tacle must not break or leak.
6.1.9.2.2 Hydraulic Pressure Test
The hydraulic pressure test must consist of:
(a) Number of samples—six receptacles;
(b)Method of testing and pressure applied—the recep-tacles must resist a test pressure equal to at least 1,200 kPa;
(c)Criteria for passing the test successfully—the recep-tacles must not show major distortions, leaks or similar faults, but a slight symmetrical distortion of the base, or one affecting the profile of the top end is allowed, provided that the receptacle passes the bursting test.
6.1.9.2.3 Bursting Test
The bursting test must consist of:
(a)Number of samples—six receptacles. These may be the same ones used in the hydraulic pressure test;
(b)Method of testing and pressure applied—a hydraulic pressure at least 20% higher than the test pressure as mentioned in 6.1.9.2.2 must be applied;
(c)  Criteria for passing the test successfully—no recep-tacles may leak.
6.1.9.2.4 Leakage Test
The leakage test must consist of:
(a) Number of samples—every aerosol;
(b) Method of testing—in accordance with 6.4.4.2.2.2 or
6.4.4.3 approved by the competent authority.
6.1.10 Metal or Plastic
Flexible Tubes
The materials of construction of flexible tubes and their closures must, where in contact with the organic peroxide, not affect the thermal stability.
6.2 Specifications for UN Outer, Single and Composite Packagings
6.2.0 General
6.2.0.1 All packagings described in Subsection 6.2, must pass the tests in Subsection 6.3 which are appli-cable to the type of packaging and contents, unless specifically exempted by these Regulations.
6.2.0.2 Any permeation of the substance contained in the packaging must not constitute a danger under normal conditions of transport.
6.2.1 Steel Drums
6.2.1.1 This paragraph contains the specifications for:
6.1
● 1A1—non-removable head steel drums;
to
● 1A2—removable head steel drums.
6.2
6.2.1.2 Body and heads must be constructed of steel sheet of a suitable type and of adequate thickness in relation to the capacity of the drum and to its intended use.
Note:
In the case of carbon steel drums, “suitable” steels are identified in ISO 3573:1999 “Hot rolled carbon steel sheet of commercial and drawing qualities” and ISO 3574:1999 “Cold reduced carbon steel of commercial and drawing qualities”. For carbon steel drums below 100 L, “suitable” steels in addition to the above standards are also identified in ISO 11949:1995 “Cold reduced electrolytic tinplate”, ISO 11950:1995 “Cold reduced electrolytic chromium/chromium oxide coated steel” and ISO 11951:1995 “Cold reduced blackplate in coil form for the production of tinplate or electrolytic chromium/ chromium-oxide coated steel”.
6.2.1.3 Body seams must be welded on drums intended to contain more than 40 L of liquids. Body seams must be mechanically seamed or welded on drums intended to contain solids, or 40 L or less of liquids.
6.2.1.4 Chimes must be mechanically seamed or welded. Separate reinforcing rings may be applied.
6.2.1.5 The body of a drum of a capacity greater than 60 L must, in general, have at least two expanded rolling hoops or, alternatively, at least two separate rolling hoops. If there are separate rolling hoops, they must be fitted tightly on the body and so secured that they cannot shift. Rolling hoops must not be spot welded.
6.2.1.6 Openings for filling, emptying and venting in the bodies or heads of non-removable head (1A1) drums must not exceed 7 cm in diameter. Drums with larger openings are considered to be of the removable head type (1A2). Closures for openings in the bodies and
584
heads of drums must be so designed and applied that they will remain secure and leak-proof under normal conditions of transport. Closure flanges may be mechan-ically seamed or welded in place. Gaskets or other sealing elements must be used with closures, unless the closure is inherently leak-proof.
6.2.1.7 Closure devices for removable head drums must be so designed and applied that they will remain secure and drums will remain leak-proof under normal conditions of transport. Gaskets or other sealing elements must be used with all removable heads.
6.2.1.8 If materials used for body, heads, closures and fittings are not in themselves compatible with the contents to be transported, suitable internal protective coatings or treatments must be applied. These coatings or treatments must retain their protective properties under normal conditions of transport.
6.2.1.9 Maximum capacity of drum: 450 L.
6.2.1.10 Maximum net weight: 400 kg.
6.2.2 Aluminium Drums
6.2.2.1 This paragraph contains the specifications for:

1B1—non-removable head aluminium drums;

1B2—removable head aluminium drums.
6.2.2.2 Body and heads must be constructed of alu-minium at least 99% pure or of an aluminium base alloy. Materials must be of a suitable type and of adequate thickness in relation to the capacity of the drum and to its intended use.
