Introduction

The manual is in two main parts:

1. Introduction

The introduction summarises the duties and responsibilities of the HV certifier which are set out in detail in the relevant Notice(s) of Appointment, explains the inspection and certification process, complaints procedures, inspection premises and equipment, and appointment of HV certifiers.

Also included are definitions and abbreviations and sample certification documents.

The term ‘he’ in respect of an HV certifier, is intended to include ‘she’.

2. Technical

This part of the manual covers the requirements for the certification of modifications, mounting of components, design and manufacture of vehicles and components and repairs to individual aspects of heavy vehicle components, structures and systems.

• the HV certifier identifies each system, structure, component, aspect or performance characteristic affected by the modification, manufacture or repair
• the HV certifier selects the corresponding chapter(s) from the technical part and inspects the vehicle to determine whether the requirements have all been met.

Each chapter of the technical part consists of up to six parts:
