Regulation 38
The following table indicates which modules are to be followed when undertaking conformity assessment procedures.
| Category of transportable pressure equipment | Modules |
|---|---|
| Pressure receptacles for which the product of the test pressure and the capacity is no more than 30 MPa x litre (300 bar x litre) | A1, D1 or E1 |
| Pressure receptacles for which the product of the test pressure and the capacity is more than 30 and no more than 150 MPa x litre (300 and 1,500 bar x litre respectively) | H, B in combination with E, B in combination with C1, B1 in combination with F, or B1 in combination with D |
| Pressure receptacles and tanks for which the product of the test pressure and the capacity exceeds 150 MPa x litre (1,500 bar x litre) | G, H1, B in combination with D, or B in combination with F |
1. Transportable pressure equipment must be subject, at the choice of the manufacturer, to one of the conformity assessment procedures laid down for the category in which it is classified. In the case of pressure receptacles or their valves or other accessories used for transport by road or by rail, the manufacturer may also choose to apply one of the set procedures for the higher categories.
2. As part of the quality assurance procedures, the notified body must, when making unannounced visits, take a sample of the equipment at the manufacturing or storage premises for the purpose of carrying out a check, or having a check carried out, to verify compliance with the requirements of Part 4 of these Regulations. For this purpose the manufacturer must inform the notified body of the production programme planned. The notified body must make at least two visits during the first year of manufacture. The frequency of subsequent visits will be determined by the notified body on the basis of the criteria set out in paragraph 4.4 of the relevant modules in Schedule 4.
