This part of ISO 13472 describes a test method for measuring in situ the sound absorption coefficient of road surfaces as a function of frequency in the range from to . Normal incidence is assumed. However, the test method can be applied at oblique incidence although with some limitations (see annex F). The test method is intended for the following applications: — determination of the sound…

Is applicable to portable voltage detectors with or without a built-in power source to be used on electrical systems for voltages of 1 kV to 36 kV a.c., and frequencies from 15 Hz to 60 Hz. This part applies only to resistive voltage detectors used in contact with the part to be tested, as a single unit or as a separate device completed by an adaptable insulating pole covered in IEC 60855 or IEC…

This International Standard specifies technical requirements for windows, portlights, hatches, deadlights and doors on small craft of hull length up to 24 m, taking into account the type of craft, its design category, and the location of the appliance. The appliances considered in this International Standard are only those that are critical for the craft's watertightness, i.e. those that…

This standard specifies lighting requirements for indoor work places and for people to perform the visual tasks efficiently, in comfort and safety throughout the whole work period. This standard does not explain how lighting systems or techniques should be designed to optimise solutions for specific work places. These may be found in the relevant CIE guides and reports.

This International Standard specifies two methods, i.e. flow injection analysis (FIA) and continuous flow analysis (CFA), for the determination of soluble silicate ions in various types of water (such as ground, drinking, surface, leachate and waste water). Both methods are applicable to the determination of a mass concentration of silicate (SiO 2) ranging from 0,2 mg/l to 20 mg/l (with working…

Introduction 1.1 The ISO 14000 Series The ISO 14000 series is made up of voluntary standards that provide organizations with guidance on how to manage the environmental aspects of their activities, products, and services more effectively. The series has been developed, and is continually reviewed, to support organizations in their efforts to control environmental impacts in a responsible…

ISO 15550 establishes the framework for ISO engine power measurement standards. It specifies standard reference conditions and methods of declaring the power, fuel consumption, lubricating oil consumption and test methods for internal combustion engines in commercial production using liquid or gaseous fuels. ISO 15550 applies to reciprocating internal combustion engines (spark-ignition or…

This International Standard is intended as a guideline for clinical researchers working with condoms. It suggests a series of laboratory tests to be conducted on the products to be used in any clinical investigation, so that it will be easier to relate the clinical results to the design and quality of the condoms used. This International Standard is not applicable to the design of clinical…

This International Standard specifies two methods for the determination of the resistance of rubber to abrasion by means of a rotating cylindrical drum device. The methods involve determination of the volume loss due to the abrasive action of rubbing a test piece over a specified grade of abrasive sheet. Method A is for a non-rotating test piece and method B for a rotating test piece. For each…

This part of ISO 10333 specifies requirements, test methods, instructions for use and maintenance, marking, labelling and packaging, as appropriate, for vertical rails and vertical lifelines which incorporate a sliding-type fall arrester. When connected to a full-body harness as specified in ISO 10333-1, vertical rails and vertical lifelines which incorporate a sliding-type fall arrester…
