Full title and description

DIN EN 12573-3:2000-12 — "Welded static non-pressurised thermoplastic tanks - Part 3: Design and calculation for single skin rectangular tanks." This document is the German (DIN) adoption of the European standard EN 12573-3 and gives requirements and calculation rules for the design of welded, stationary, non‑pressurised rectangular tanks made from thermoplastic materials.

Abstract

This part of EN 12573 specifies design principles and calculation methods for single‑skin rectangular (parallelepiped) above‑ground tanks fabricated from thermoplastics such as polyethylene (PE), polypropylene (PP), PVC and PVDF. It covers hydrostatic loads and long‑term/short‑term stresses relevant to welded thermoplastic tanks and provides rules for dimensions, wall and base thicknesses and related design checks.

Scope

EN 12573‑3 applies to welded, stationary, non‑pressurised single‑skin rectangular tanks made from thermoplastics (PE, PP, PVC, PVDF). The standard gives design and calculation methods for tank walls, bases and supports under hydrostatic load and typical service temperatures; it addresses structural design checks and dimensional rules required to ensure safe service (does not generally cover pressurised vessels or specialised containment systems). National adoptions of the EN text may add editorial differences or forewords.

Key topics and requirements

• Materials covered: polyethylene (PE), polypropylene (PP), poly(vinyl chloride) (PVC) and poly(vinylidene fluoride) (PVDF).
• Design and calculation rules for single‑skin rectangular (parallelepiped) tanks, including wall and base thickness determination.
• Consideration of hydrostatic loads and short‑term/long‑term material behaviour (creep / stress relaxation) in calculation methods.
• Requirements for welded joints and construction details relevant to structural strength of thermoplastic tanks.
• Dimensional guidance for shells, stiffening, supports and nozzles as applicable to rectangular tanks.
• Reference to other parts of EN 12573 for general principles and other tank geometries (cylindrical tanks, flanged joints, etc.).

Key technical topics follow the EN 12573 series structure and the CEN technical committee guidance for static thermoplastic tanks.

Typical use and users

Practicing structural and mechanical engineers, tank designers and fabricators, quality and compliance personnel in chemical, water treatment, food & beverage and industrial storage sectors, and national standards/approval bodies use this standard when designing, manufacturing or assessing welded thermoplastic rectangular tanks for atmospheric storage of liquids. It is also used as a reference for procurement specifications and conformity checks.

Related standards

EN 12573 is a multipart European standard. Closely related parts include EN 12573‑1 (General principles), EN 12573‑2 (Calculation of vertical cylindrical tanks) and EN 12573‑4 (Design and calculation for flanged joints). Other guidance documents and industry publications on thermoplastic tank specification, installation and inspection (for example EEMUA guidance) are commonly used alongside EN 12573.
