DD ISO PAS — ISO Publicly Available Specifications Single-File Series Overview (6 Standards)

🚗 DD ISO PAS is the prefix under which BSI publishes ISO Publicly Available Specifications (ISO/PAS) as Drafts for Development (DD). An ISO/PAS is a specification developed by ISO for subjects where a formal International Standard (IS) is not yet warranted but a specification is needed quickly; BSI publishes it as a DD (some verbatim), stating explicitly that it “is not to be regarded as a British Standard” and is for trial application to gain experience, normally re-examined within 3 years for conversion into an International Standard, extension or withdrawal. This batch collects 6 DD ISO/PAS documents, concentrated in road vehicles (roof load carriers, product data exchange between chassis and bodywork manufacturers — BEP, visual inspection of brake-lining friction materials) and supply chain security management systems (the ISO 28000 family specification, best practice and certification-body requirements trilogy).

1. Series Overview and Document Inventory 📌

All 6 documents in this batch are single-file series; 11154 supersedes BS AU 266-1:1996 and 28000 is a verbatim reproduction. The table below lists the complete inventory and main technical content.

2. Representative Standard (1): DD ISO/PAS 11154 Roof Load Carriers 🧳

DD ISO/PAS 11154:2006 specifies the product requirements of road-vehicle roof load carriers (roof racks/roof boxes), superseding BS AU 266-1:1996 (ISO 11154-1:1995). Roof load carriers are mounted on the vehicle roof (with side rails or fixed points) to carry luggage, bicycles and other loads. The specification covers basic requirements (load capacity, connection/fixing to the vehicle, anti-loosening, stability, aerodynamic/noise considerations), material and safety requirements (structural strength, dynamic/static tests, corrosion resistance), and installation and use-information requirements, ensuring reliable fixing and safe use of roof-loading devices. The specification notes that a PAS is “a Technical Specification not fulfilling the requirements for a standard but made available to the public”, and BSI published it as a DD for trial.

It is the responsibility of AUE/9 (Automobile details and accessories). Standardisation of roof load carriers and their mounting interfaces has practical value for luggage-transport safety and prevention of roof-load accidents; the later ISO 11154 series further developed roof-load-carrier requirements into a formal standard family.

3. Representative Standard (2): DD ISO/PAS 21308-1 Chassis-Bodywork Product Data Exchange (BEP) 🔗

DD ISO/PAS 21308-1:2007 specifies Part 1: General principles of product data exchange between chassis and bodywork manufacturers (Bodywork Exchange Platform, BEP). Commercial vehicles (trucks/buses) have their chassis manufactured by chassis manufacturers (e.g. Daimler, Volvo, Scania, IVECO) and their bodies, tanks, superstructures completed by bodywork/converters; the two sides must exchange substantial product data (chassis dimensions, loads, electrical interfaces, weight distribution) to complete compliant conversion design. The specification defines the general principles of BEP data exchange — including the participants and process of data exchange, unified identification of objects, organisation of the data dictionary, and the division of parts (after Part 1 general principles, later parts cover chassis data, body data, electrical interfaces, etc.) — the basis of standardising commercial-vehicle “chassis-superstructure co-design” data.

It is the responsibility of AUE/9 (Automobile details and accessories). The BEP concept was initiated by the European commercial-vehicle industry (ACE system), aiming to reduce conversion-design rework and data ambiguity through a standardised product data dictionary, supporting modular superstructures and rapid compliant development.

4. Representative Standard (3): DD ISO/PAS 22574 Visual Inspection of Brake Lining Friction Materials 🔍

DD ISO/PAS 22574:2007 specifies the visual inspection of brake-lining friction materials for road vehicles. Surface and edge defects of brake linings/brake pads (cracks, porosity, delamination, contamination, insufficient curing, edge breakage) directly affect braking performance and safety. The specification defines the types of friction-material surface defects, acceptable/not-acceptable judgement criteria (e.g. crack length and location, porosity distribution, edge chips) and the conditions and recording requirements of visual inspection — an effective supplement to factory and incoming inspection of brake linings, working with brake-pad performance test standards (e.g. the ISO 26865 series).

It is the responsibility of AUE/11 (Braking systems). Visual inspection is the “first line of defence” of brake-lining quality control; standardised judgement criteria reduce subjective differences between inspectors and safeguard driving safety.

5. Representative Standards (4): The Supply Chain Security Trilogy (28000 / 28001 / 28003) 🚢

This batch includes three core documents of the Supply Chain Security Management System (SCSMS), all the responsibility of SME/32 (Ships and marine technology), serving the systematic management of international supply-chain security (e.g. anti-terrorism, anti-smuggling, cargo security):

• DD ISO/PAS 28000:2005 (specification) — specifies the requirements of a supply chain security management system: an organisation manages security of its people, assets, cargo and information through a process approach of “security policy — security risk assessment — security management plan — implementation and operation — checking and corrective action — management review”. It is the foundational specification of the ISO 28000 family, following the management-system structure of ISO 9001/14001 and originally emerging from the IMO supply-chain security initiative (paired with the ISPS port-facility rules);
• DD ISO/PAS 28001:2006 (best practice) — specifies best practices for implementing supply chain security: assessments and plans: providing supply-chain security vulnerability/threat assessment methods, security improvement measures, and a guide to developing the supply-chain security plan — the “implementation toolbox” of 28000;
• DD ISO/PAS 28003:2006 (certification-body requirements) — specifies requirements for bodies providing audit and certification of supply chain security management systems: the “supply-chain version of ISO 17021”, ensuring impartiality and competence of SCSMS certification bodies and supporting third-party certification of SCSMS.

The ISO 28000 family was subsequently published formally in 2007 (ISO 28000:2007 and companion standards), developing ISO 28004 (implementation guide) etc., becoming an important support of international supply-chain security certification (e.g. C-TPAT/AEO mutual recognition).

6. Remaining Standards at a Glance 📋

• Data-exchange basis: the “general principles” of 21308-1 also specify the common naming rules for BEP objects, units and the data-dictionary maintenance mechanism, providing a consistent basis for the later parts (chassis, superstructure, electrical interfaces).
• Management-system commonality: 28000/28001/28003 share the “policy — planning — implementation — checking — improvement” (PDCA) framework, compatible with ISO 9001/14001/45001 for integrated management.
• Document status: BSI notes for all documents in this batch “not to be regarded as a British Standard”, and 28000 particularly cautions in its foreword that it is “still under development, with insufficient field data, and may be subject to significant change”.
