1.1 General This document specifies the requirements for portable locating leak detectors and fixed gas detectors for refrigerants. Locating detectors used in factories for manufacturing processes are not included in the Scope of this document. 1.2 Product application This document applies to different applications and environments such as plant and machine rooms, production rooms, cold rooms, supermarkets, occupied spaces like offices and hotels. 1.3 Product performance This document specifies minimum requirements for sensitivity, operating range, response time, environmental conditions and cross sensitivity from interference gases. 1.4 Product installation This document gives guidance of suitable technology, location of detection points, interconnection with secondary equipment (e.g. initiation of mechanical ventilation, personnel warning, and equipment shutdown). 1.5 Service and maintenance This document gives guidance for service and maintenance: Sensors and mechanical equipment have a limited operating life and require regular performance verification to ensure conformity.

 

This document describes a method for the ultrasonic-testing of uncoated flat austenitic and austenitic-ferritic stainless steel product for internal discontinuities. This document is applicable to flat product in nominal thickness range of 6 mm to 200 mm. This document also defines four quality classes for the flat product body (classes S1, SA, S2 and S3) and four quality classes (E1, E2, E3, E4) for the edges (see Clause 15). A list of equivalent terms in several European languages is given in Annex A.

 

This document is applicable to citric acid used as an antiscalant for membranes in the treatment of water intended for human consumption. It describes the characteristics and specifies the requirements and the corresponding analytical methods for citric acid. It gives information on its use as an antiscalant for membranes in water treatment. It also provides guidance relating to safe handling and use (see Annex B).

 

In this document, a test sample is dissolved in water, and the dilution of the solution is to a known mass. The solution is nebulized into an inductively coupled plasma/atomic emission spectrometer (ICP-OES), and the intensity of the emitted light from metal ions is measured simultaneously. This document is applicable to the determination of impurity metal ions such as aluminium (Al), calcium (Ca), cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), potassium(K), magnesium (Mg), sodium (Na), nickel (Ni), lead (Pb) and zinc (Zn) in lithium hexafluorophosphate (LiPF6). The method is suitable for mass concentrations of impurity metallic ions in LiPF6 below 10 mg/kg. The scope of this method may be extended to higher mass concentrations of impurity metallic ions in LiPF6 if it can be shown that additionally occurring interferences are considered and corrected for carefully. It is up to the user to demonstrate the fitness for purpose.

 

The method is applicable to sulphur contents between 0,002 % (m/m) and 0,10 % (m/m). Specifies principle, reagents and material, apparatus, sampling, procedure, expression of results and test report. Annex A gives additional information on the international cooperative tests. Annex B represents the precision date graphically. Annex C deals with induction furnaces and infrared sulfur analysers.

 

ISO 13350:2015 deals with the determination of those technical characteristics needed to describe all aspects of the performance of jet fans as defined in ISO 13349. It does not cover those fans designed for ducted applications, nor those designed solely for air circulation, e.g. ceiling fans and table fans. The test procedures described in this International Standard relate to laboratory conditions. The measurement of performance under on-site conditions is not included.

 

This part of ISO 27327 establishes uniform methods for laboratory testing of air curtain units to determine aerodynamic performance in terms of airflow rate, outlet air velocity uniformity, power consumption and air velocity projection, for rating or guarantee purposes. This part of ISO 27327 is not applicable to the specification of test procedures to be used for design, production or field testing.
