This British Standard gives recommendations for basic workmanship and tasks carried out in relation to the installation of profiled fibre cement sheets for roofing and external wall cladding including associated fittings and accessories.

This code of practice also gives recommendations for design specific to the use of profiled fibre cement sheets for roof and wall cladding on buildings.

NOTE 1 For design aspects of profiled fibre cement sheeting reference should be made to BS 5427-1.

NOTE 2 This code of practice makes no reference to asbestos cement.

This PAS sets out the minimum requirements for the safe design, manufacture and testing of flywheels that are used in mobile applications (automobiles, buses, trains, trams, etc.) in the public domain. It includes the generic safety considerations associated with operation in a vehicle that shall be taken into account by the vehicle designers.

The intended audience of this PAS are the designers, manufacturers and OEM installers of flywheels, with particular reference to mobile applications.

This PAS can be used for stationary applications but is more stringent than is required for stationary applications.

This PAS specifies requirements for establishing, implementing and maintaining a home and/or personal care (HPC) product safety system and associated prerequisite programmes (PRP) to assist in the manufacture of HPC products and the raw/packaging materials used to manufacture these products.

Examples of home care products include, but are not limited to:

• bleach;
• table polish;
• bathroom cleaner;
• kettle de-scaler;
• limescale remover; and
• antibacterial wipes.

This PAS does not address vacuum cleaners, washing machines or any other electric devices designed for household cleaning.

Examples of personal care products include, but are not limited to:

• shampoo;
• hair conditioner;
• deodorant;
• moisturiser;
• nail polish;
• soap; and
• hand cream. 

This PAS is applicable to all organizations, regardless of size or complexity, which are involved in manufacturing HPC products or the raw/packaging materials used to manufacture these products and wish to implement a HPC product safety system and associated PRPs. To this effect, it takes a risk-based approach with the intention that it will help manufacturers identify hazards and critical control points, and develop plans to mitigate against those hazards and risks.

HPC product, raw and packaging material manufacturing operations are diverse in nature and not all of the requirements specified in this PAS apply to an individual establishment or process. Accordingly:

• Manufacturers of home care products shall comply with the main    requirements of this PAS.
• Manufacturers of personal care products shall comply with the main    requirements of this PAS, and in addition, the requirements of Annex A.  

This British Standard gives recommendations for the design, planning, installation, testing and maintenance of sound systems intended for communicating speech, music and/or other signals, including systems conveying emergency messages or signals that are not connected to a fire detection system.

NOTE 1 For systems used for conveying emergency messages, recommendations are given in BS 5839-8.

This standard is intended for use by clients, designers, installers and those responsible for commissioning, testing, operation and maintenance of sound systems.

This standard is not applicable to:

a) voice-alarm systems within the scope of BS 5839-8;

b) emergency voice communication systems within the scope of BS 5839-9;

c) simultaneous interpretation systems (see ISO 2603);

d) some of the aspects associated with recording studios, and applies only to some types of broadcasting studio;

e) home entertainment systems;

f) systems intended only to modify the perceived acoustic characteristics of the space;

g) manual fire detection systems;

h) audio conferencing systems.

This standard is not applicable to cinema sound systems.

NOTE 2 Cinema sound technology is evolving very rapidly at present, due partly to the elimination of film stock in favour of digital distribution, and the increased practicability of multi-channel sound systems with tens of channels. Existing standards such as BS 5550-3.4.9 are likely to be replaced by completely new standards within a few years. It is therefore not at present practicable to give advice on these systems in this standard.

This design qualification standard is applicable to solar trackers for photovoltaic systems but may be used for other solar applications. The standard defines test procedures for both key components and for the complete tracker system. In some cases, test procedures describe methods to measure and/or calculate parameters to be reported in the defined tracker specification sheet. In other cases the test procedure results in a pass fail criteria.

The objective of this design qualification standard is twofold.

First, this document ensures the user of the said tracker that parameters reported in the specification sheet were measured by consistent and accepted industry procedures. This provides the customer with a sound basis for comparing and selecting a tracker appropriate to their specific needs. This standard provides industry-wide definitions and parameters for solar trackers. Each vendor can design, build, and specify the functionality and accuracy with uniform definition. This allows consistency in specifying the requirements for purchasing, comparing the products from different vendors, and verifying the quality of the products.

Second, the tests with pass/fail criteria are engineered with the purpose of separating tracker designs that are likely to have early failures from those designs that are sound and suitable for use as specified by the manufacturer. Mechanical and environmental testing in this standard is designed to gauge the tracker’s ability to perform under varying operating conditions as well as to survive extreme conditions. Mechanical testing is not intended to certify structural and foundational designs, as this type of certification is specific to local jurisdictions, soil types, and other local requirements.
