Understanding BS EN 12573: The Essential Standard for Thermoplastics Tank Design (PDF Guide) Introduction In the world of industrial storage and chemical processing, the safe containment of aggressive liquids is non-negotiable. While stainless steel and concrete have historically dominated this space, welded thermoplastics have emerged as a superior alternative for corrosive environments. However, a tank is only as reliable as the standard it was built to. Enter BS EN 12573 . For engineers and fabricators across the UK and Europe, this standard is the definitive code of practice for the design, calculation, and construction of welded static tanks made from thermoplastics. If you are searching for a bs en 12573 pdf , you are likely involved in a project requiring regulatory compliance, safety validation, or high-performance chemical storage. This article explains everything you need to know about the standard and where to legitimately access it. What is BS EN 12573? BS EN 12573 is a European standard, adopted as a British Standard (BS), that specifically addresses Welded static non-pressurised tanks made of thermoplastic material . Unlike general plastic welding codes, this standard focuses exclusively on tanks that are subject to atmospheric pressure or very low internal overpressure (typically up to 0.5 bar). The standard is divided into several parts, each covering a critical aspect of tank design and safety:

Part 1: General principles (Definitions, symbols, material selection) Part 2: Calculation of vertical cylindrical tanks Part 3: Calculation of rectangular tanks Part 4: Flanges and fittings (Connection design)

Originally derived from German technical rules (DVS 2205), BS EN 12573 has become the gold standard for verifying that a thermoplastic tank will withstand hydrostatic pressure, wind loads, and operational stresses without deforming or failing. Why Do You Need the BS EN 12573 PDF? Searching for the bs en 12573 pdf is a common requirement for three primary user groups: 1. Design Engineers If you are calculating wall thickness for a 10,000-liter polypropylene (PP) tank, you cannot guess. The standard provides specific formulas for stress analysis, considering factors like material creep over time (long-term behavior). Without the PDF, your calculations lack legal traceability. 2. Fabrication Shops To achieve ISO 9001 or specific client sign-off, fabricators must prove their tanks meet EN 12573. The standard dictates welding procedures, joint types (butt, fillet, overlap), and inspection criteria. Having the PDF on hand ensures your quality control matches the book. 3. End Users & Safety Inspectors Regulatory bodies (like HSE in the UK) often reference harmonized standards. If a tank bursts, the first question asked is: "Was it designed to BS EN 12573?" Possessing the PDF allows you to audit supplier proposals and ensure your asset is legally defensible. Key Technical Requirements of EN 12573 Understanding the content of the standard is vital before you download your copy. Here are the core technical pillars: Material Properties The standard mandates the use of specific thermoplastics, including: What is BS EN 12573

Polypropylene (PP-H, PP-B, PP-R) Polyethylene (PE-HD, PE-LD, PE-MD) Polyvinylidene fluoride (PVDF) Polyvinyl chloride (PVC-U, PVC-C)

It requires designers to use different allowable stress values based on temperature and service life (usually 10 to 25 years). Safety Factors Unlike metal tanks, plastics creep. EN 12573 introduces a global safety factor (typically 4 to 8 depending on the polymer) to account for long-term deformation. The PDF contains detailed tables for "Minimum wall thickness" based on tank diameter and specific gravity of the liquid. Calculation for Rectangular vs. Cylindrical One of the most common mistakes is using cylindrical formulas for a rectangular tank. Part 2 of the standard deals with cylindrical tanks using membrane stress theory, while Part 3 covers the complex bending stresses on flat panels of rectangular tanks, including reinforcement rib spacing. Nozzle and Flange Design (Part 4) Failures often occur at connections. Part 4 specifies how to reinforce branch connections, standardizes thermoplastic flange dimensions (often aligning with PN10 drilling), and details the embedment of metal inserts.
