This European Standard specifies the requirements and associated test methods applicable to ductile iron fittings, ductile iron and mild steel couplings and flange adaptors and their joints to be used with poly(vinyl chloride) (PVC-U) pipes or polyethylene (PE) pipes. It is in conformity with EN 1452-1 to -5, ENV 1452-6 and -7 and EN 12201-1 to -5 respectively, for the construction of pipelines:
- to convey water (e.g. water intended for human consumption);
- with or without pressure;
- to be installed below or above ground, inside or outside buildings.
This European Standard is not intended to cover sewerage applications, where additional requirements may be necessary.
This European Standard is applicable to fittings which are:
- manufactured with socketed, flanged or spigot ends;
- supplied externally and internally coated;
- suitable for PE and PVC-U pipes with fluid temperatures between 0°C and 25°C, excluding frost, and for pressures up to 16 bar (PFA). For higher temperatures (up to 45°C for PVC-U or 40°C for PE) the PFA is derated as given in EN 1452 and EN 12201;
- not intended for use in areas subjected to reaction to fire regulations.
NOTE 1 This does not preclude special arrangements for the products to be used at higher temperatures. Temperature limitations and pressure limitations are those coming from the PVC-U or PE pipes.
This European Standard covers ductile iron fittings, couplings and flange adaptors cast by any type of foundry process or manufactured by fabrication of cast components, as well as corresponding joints, in a size range extending from DN 60 to DN 700, to be used with pipes of external diameter from 63 mm to 710 mm.
As long as no equivalent European Standard exists for mild steel accessories, this European Standard also covers couplings and flange adaptors for use with PVC-U and PE pipes which are fabricated partly or entirely from mild steel as well as corresponding joints, in a size range extending from DN 60 to DN 700, to be used with pipes of external diameter from 63 mm to 710 mm.
This European Standard specifies requirements for materials, dimensions and tolerances, mechanical properties and standard coatings. It also gives minimum performance requirements for all components, including restrained and non-restrained flexible joints. Joint design and gasket shapes are outside the scope of this standard.
This European Standard does not cover fittings, couplings and flange adaptors intended to be used with different pipe materials other than PVC-U and PE.
NOTE 2 Fittings, couplings and flange adaptors complying with the requirements of this European Standard for PVC-U also usually meet the requirements for PVC-O and PVC-A pipes. Where this is not the case, the manufacturer is expected to declare this in the relevant literature.
NOTE 3 In this European Standard, all pressures are relative pressures, expressed in bars (100 kPa = 1 bar).

This document is a specification for vertical, cylindrical tank systems, built on site, above ground and of which either the primary liquid container or the liquid tight barrier is made of steel. The secondary liquid container, if applicable, can be of steel or of concrete or a combination of both. A primary liquid container made of pre-stressed concrete is excluded from the scope of this document.
This document provides general requirements and specifies principles and application rules for the structural design of the tank system during construction, testing, commissioning, operation (accidental included), and decommissioning. This document applies to all tank system components attached to and located within the liquid, vapour, purge gas, membrane or membrane tank outer containers of the tank system. It does not address the requirements for ancillary equipment such as pumps, pumpwells, valves, instrumentation, external staircases and walkways, roof mounted platforms, external pipe supports, etc. The requirements for those components are covered by the relevant European Standards, structurally designed in accordance with Eurocodes where appropriate, and meeting applicable safety regulations.
This document also does not address tank system operating procedures unless specified for determination of the relevant resistance and protection criteria for the tank systems. It specifies minimum performance requirements for the tank system, tank system foundation and protection systems. From a process piping standpoint, the scope of this document is limited to the following boundaries:
a) the face of the first flange outside of the tank in bolted flanged connection;
b) the first threaded joint outside of the tank in threaded connection;
c) the first circumferential pipe welded joint outside of the tank in welding-end pipe connection, which does not have a flange.
This document is applicable to storage tank systems designed to store products, having an atmospheric boiling point below ambient temperature, in a dual phase, i.e. liquid and vapour. The equilibrium between liquid and vapour phases being maintained by cooling down the product to a temperature equal to, or just below, its atmospheric boiling point in combination with a slight overpressure in the storage tank system.
The maximum design pressure of the tank systems covered by this document is limited to 500 mbar. For higher pressures, reference can be made to EN 13445, Parts 1 to 5.
The operating range of the gases to be stored is between 0 °C and −196°C.
The tank systems covered by this document are used to store large volumes of hydrocarbon products, ammonia and other non-hydrocarbon gases with low temperature boiling points, generally called “Refrigerated Liquefied Gases” (RLGs). Typical products stored in the tank systems are: methane, ethane, propane, butane, ethylene, propylene, butadiene (this range includes the Liquefied Natural Gas (LNG’s) and Liquefied Petroleum Gas (LPG’s)), ammonia, nitrogen, oxygen and argon.
NOTE 1 Properties of the gases are given in Annex A.
The requirements of this document cannot cover all details of design and construction because of the variety of sizes and configurations that may be employed. Where complete requirements for a specific design are not provided, the intention is for the designer, subject to approval of the purchaser's authorized representative and of the regulatory body, to provide design and details that are as safe as those laid out in this document.
EN 14620 consists of multiple parts. This document specifies general requirements for the tank system concept, selection and general design considerations.
In case of a conflict between general requirements of this document and the requirements in other parts of EN 14620 related to a specific liquefied gas, the product-specific requirements set forth in the other parts prevail.

This document specifies the detection of Clostridium (C.) perfringens.
This document is applicable to:
— products intended for human consumption;
— products intended for animal feeding;
— environmental samples in the area of food and feed production and handling;
— samples from the primary production stage.
This horizontal method was originally developed for the examination of all samples belonging to the food chain. Based on the information available at the time of publication of this document, this method is considered to be fully suited to the examination of all samples belonging to the food chain. However, because of the large variety of products in the food chain, it is possible that this horizontal method is not appropriate in every detail for all products. Nevertheless, it is expected that the required modifications are minimized so that they do not result in a significant deviation from this horizontal method.
NOTE Interlaboratory studies with a small number of participating laboratories (<10) were conducted for the following food categories:
— ready-to-eat, ready-to-reheat meat products;
— eggs and egg products (derivates);
— ready-to-eat, ready-to-reheat fishery products;
— processed fruits and vegetables;
— infant formula and infant cereals (with probiotics);
— multi-component foods or meal components.
It has also been validated with a small number of participating laboratories for the following other category:
— environmental samples (food or feed production).
Since the method is not commonly used for samples in the primary production stage, this category was not included in the interlaboratory study. Therefore, no performance characteristics were obtained for this category. The method has not been validated for the category ‘pet food and animal feed’, as the test samples used for the interlaboratory study were already naturally contaminated with C. perfringens. Given the limited number of participating laboratories in the interlaboratory studies, the calculated performance characteristics can be used as indicative values of the method performance. For detailed information on the validation, see Clause 11 and Annexes C to F.
