PD CR — CEN Reports Single-File Series Overview (11 Standards)
Published Document — CEN Reports（CR）Single-File Series Overview（11 Standards）
📘 PD CR is the prefix under which BSI publishes CEN Reports (CR) as Published Documents (PD). A CEN Report is developed by a CEN technical committee for informative content (such as guidance, methodological descriptions, or data compilations) that does not yet warrant a formal European Standard (EN); BSI publishes it in the UK under the “PD” series (some as the official English-language version, some verbatim or as UK implementation). This batch collects 11 PD CR documents, covering guidance on the use of conformity procedures for unfired pressure vessels, soil improvers and growing media (user/environment/plant safety guidelines and labelling specifications), heat-meter installation guidelines, optimisation of energy recovery from packaging waste, masonry-cement workability testing, a generic non-destructive testing (NDE) data format model, recommendations for measuring emissions from treated wood in service, a purchasing guide for drinking-water treatment chemicals, and experimental determination of mechanical energy-loss coefficients of air-handling components. These documents are the accompanying “background/guidance” material to formal EN standards in their respective fields and have significant reference value.
💡 CEN Reports (CR) differ from EN standards: a CR is an informative document that carries no mandatory requirements and need not be published as a national standard by members, but it provides authoritative technical guidance and background. When BSI publishes a CR as a PD, most documents note that they “do not constitute a formal British Standard”.

⚠️ In this batch, the UK title of PD CR 14269:2001 was modified to add the words “of products” (missing from the CEN final text; BSI notified CEN); PD CR 14378:2002 incorporates Corrigendum No.1 (replacing Figures A.4/A.5/A.6); PD CR 1752 is a scanned copy. Check the specific document status before use.
2. Representative Standard (1): PD CR 13445-7 Guidance on Pressure-Vessel Conformity Procedures 🏭
EN 13445 (Unfired Pressure Vessels) is the harmonised standard series under the EU Pressure Equipment Directive (PED 2014/68/EU); Parts 1–6 cover general, materials, design, fabrication, inspection & testing, and filling/commissioning respectively. PD CR 13445-7:2002, as a component of the series, provides guidance on the use of the conformity procedures — how to organise design, manufacture, certification and CE marking under the conformity-assessment modules (e.g. modules A, D, H) required by the PED.
The document is the responsibility of PVE/1 (Pressure vessels), subcommittee PVE/1/17 (Inspection, testing and acceptance criteria). It is a key supporting document for understanding how the technical clauses of EN 13445 interface with the legal requirements of the PED: pressure-vessel manufacturers and Notified Inspection Bodies (NIB) use it as the operating reference for design review, type testing, final assessment and documentation, making it a core reference for European pressure-vessel CE certification practice.
3. Representative Standards (2): Soil Improvers and Growing Media Companion (13455 / 13456) 🌱
PD CR 13455:1999 provides guidelines for the safety of users, the environment and plants for soil improvers and growing media, covering assessment and risk management of use safety (e.g. dust, pathogens, heavy metals), environmental hazards (e.g. groundwater and soil pollution) and plant hazards (e.g. phytotoxicity); PD CR 13456:1999 specifies labelling, specifications and product schedules, providing a unified framework for composition declarations, functional descriptions, methods of use and quality parameters. Both are the responsibility of AW/20 (Top soil and other growing media), and are an important basis for standardisation and consumer-information transparency in the UK horticultural products market (composts, growing substrates), later absorbed into the formal EN 12580/13037/13652 systems.
The two documents complement each other from the “safety assessment” and “information specification” angles: the former tells users and regulators how to use safely, the latter tells the market how to label and accept honestly.
4. Representative Standard (3): PD CR 13582 Heat-Meter Installation Guide 🌡️
PD CR 13582:1999, developed by CEN/TC 176 (heat meters), provides guidelines for selecting, installing and operating heat meters. A heat meter comprises a flow sensor, a temperature-sensor pair and a calculator, used for energy-billing in heating supply. The report focuses on: selecting the meter type and nominal flow according to the metering object (apartment, building, district heating) and flow range; the effect of installation position on measurement accuracy (straight-run requirements, preventing flow disturbance and cavitation); and in-service verification, calibration and maintenance intervals. Its content works with the EN 1434 (heat meters) series and the metering requirements of the EU Energy Efficiency Directive (EED).
It is the responsibility of CPI/30 (Measurement of fluid flow in closed conduits), subcommittee CPI/30/7 (Volume flow-rate methods). In the context of heating-metering reform and “heat-by-meter billing”, this guide offers practical engineering advice for purchasers and installers.
5. Representative Standard (4): PD CR 13935 Generic NDE Data Format Model 🔬
PD CR 13935:2000, developed by CEN/TC 138 (non-destructive testing), specifies the Generic NDE data format model. Ultrasonic, radiographic, eddy-current, magnetic-particle and other NDE methods generate massive digital data, and exchange between different equipment and software has long been a pain point. The model defines the organisation of a generic data structure capable of holding all types of NDE data (raw signals, images, evaluation results, specimen and equipment information), laying the foundation for cross-manufacturer, cross-method data exchange and archiving (its later development is related to DICONDE and ISO NDE data-exchange standards).
It is the responsibility of WEE/46 (Non-destructive testing). In the Industry 4.0 and digital-inspection trend, “exchangable, traceable inspection data” is a key requirement of quality and airworthiness/pressure-safety data chains, for which this report provides an early unified framework.
6. Representative Standard (5): PD CR 14269 Purchasing Guide for Drinking-Water Treatment Chemicals 💧
PD CR 14269:2001 provides a purchasing guide for chemicals used for the treatment of water intended for human consumption. The European market has numerous drinking-water treatment chemicals (e.g. coagulants, disinfectants, pH adjusters), whose safety and purity directly affect water quality. This report gives purchasers guidance on selecting, ordering and accepting such chemicals, including product-specification conformity, purity/impurity control, batch certification, storage and labelling. The responsible committee CII/59 (Chemicals for drinking water treatment) works with the EN 878, EN 882 and other product specifications, while the purchasing guide fills in the operational “buyer’s perspective”.
Notably, BSI corrected the missing “of products” wording in the CEN text when publishing and notified CEN — reflecting the common practice of technical errata during national adoption.
✅ Overall insight: CR reports are the “guidance layer before formal standards land”. For pressure-vessel CE, horticultural product safety, heat metering, NDE data exchange and drinking-water chemical procurement, reading the CR guidance first and then checking the formal EN clauses is an efficient and robust technical path.
7. Remaining Standards at a Glance 📋

🔍 Q: Which documents in this batch are outdated or superseded?
A: As reports published 1999–2002, most content has been absorbed by later EN/ISO formal standards (e.g. the EN 12580 series inherited 13455/13456 content); refer to the latest EN or ISO, treating the CRs as historical background.
