This document specifies a method to determine the resistance to internal pressure of polyethylene (PE), crosslinked polyethylene (PE-X) and unplasticized (PA-U) pipes to verify the condition of the pipe after being subjected to a squeeze-off procedure. The equipment and procedure used to prepare the test samples and test parameters are given in this document, i.e.: a) the diameter and series of the pipe to be tested (see 6.1); b) the number of test pieces (see 6.2); c) the parameters for the hydrostatic strength tests (see 7.6) NOTE 1 Further information on the squeeze-off procedure is given in EN 12007-2 and ISO/TS 10839 for polyethylene, and CEN/TS 12007-6 for unplasticized polyamide. NOTE 2 The squeeze-off procedure is specified to limit gas flow to allow maintenance, repair or to make network connections. Squeeze-off is used in an emergency for pipes carrying other media.

ISO 16809:2017 specifies the principles for ultrasonic thickness measurement of metallic and non-metallic materials by direct contact, based on measurement of time of flight of ultrasonic pulses only.

ISO 16828:2012 defines the general principles for the application of the time-of-flight diffraction (TOFD) technique for both detection and sizing of discontinuities in low alloyed carbon steel components. It can also be used for other types of materials, provided the application of the TOFD technique is performed with necessary consideration of geometry, acoustical properties of the materials, and the sensitivity of the examination. Although it is applicable, in general terms, to discontinuities in materials and applications covered by ISO 16810, it contains references to the application on welds. This approach has been chosen for reasons of clarity as to the ultrasonic probe positions and directions of scanning. Unless otherwise specified in the referencing documents, the minimum requirements of ISO 16828:2012 are applicable. Unless explicitly stated otherwise, ISO 16828:2012 is applicable to the following product classes as defined in ISO 16811: a) class 1, without restrictions; b) classes 2 and 3, restrictions apply as stated in Clause 9. The inspection of products of classes 4 and 5 requires special procedures. These are also addressed in Clause 9. Techniques for the use of TOFD for weld inspection are described in ISO 10863. The related acceptance criteria are given in ISO 15626.

This part of ISO 19232 specifies the minimum image quality values to ensure a uniform radiographic quality.

Values are specified for these two testing classes of radiographic techniques as specified in ISO 5579.

ISO 10993-7:2008 specifies allowable limits for residual ethylene oxide (EO) and ethylene chlorohydrin (ECH) in individual EO-sterilized medical devices, procedures for the measurement of EO and ECH, and methods for determining compliance so that devices may be released. Additional background, including guidance and a flowchart showing how the standard is applied are also included in informative annexes. EO-sterilized devices that have no patient contact (e.g., in vitro diagnostic devices) are not covered by ISO 10993-7:2008.

This document gives requirements for the standardisation of methods towards harmonized procedures for determination of microplastics contents.

This document specifies the requirements and describes the test methods for check valves for water mist firefighting systems. Check valves allow the passage in the direction of flow and they prevent flow in the reverse direction. This document is applicable to check valves installed in the pipework of water mist firefighting systems.

This document specifies general construction, performance and material requirements for PN 10 thermostatic mixing valves (TMV) and includes test methods for the verification of mixed water temperature performance at the point of use below 45 °C. This does not exclude the selection of higher temperatures where available. When these devices are used to provide anti-scald protection for children, elderly and disabled persons, the mixed water temperature needs to be set at a suitable bathing temperature (body temperature approximately 38 °C) as children are at risk to scalding at lower temperatures than adults. This does not obviate the need for supervision of young children during bathing. It applies to valves intended for use on sanitary appliances in kitchens, washrooms (incl. all rooms with sanitary tapware, e.g. toilets and cloakrooms) and bath rooms operating under the conditions specified in Table 1. This document allows TMVs to supply a single outlet or a small number of outlets in a "domestic" application (e.g. one valve controlling a shower, bath, basin and/or bidet), excluding valves specifically designed for supplying a large number of outlets (i.e. for institutional use). The tests described are type tests (laboratory tests) and not quality control tests carried out during manufacture.

This document is applicable to ozone used for treatment of water intended for human consumption. It describes the characteristics of ozone, specifies tests methods for determining the ozone concentration in gases and determines rules for safe handling of the chemical ozone.

This document specifies how a preliminary welding procedure specification (pWPS) for hyperbaric wet welding is qualified by welding procedure tests.

This document specifies a test method and the minimum requirements for virucidal activity of chemical disinfectant and antiseptic products that form a homogeneous physically stable preparation when diluted with hard water – or in the case of ready-to-use products, i.e, products that are not diluted when applied, – with water. Ready-to-use-products can only be tested at a concentration up to 80 % (97 %, with a modified method for special cases) as some dilution is always produced by adding the test organisms and interfering substance. This document applies to products that are used in the medical area in the fields of hygienic handrub, hygienic handwash, instrument disinfection by immersion, surface disinfection by wiping, spraying, flooding or other means and textile disinfection. This document applies to areas and situations where disinfection is medically indicated. Such indications occur in patient care, for example: — in hospitals, in community medical facilities, and in dental institutions; — in clinics of schools, of kindergartens, and of nursing homes; and can occur in the workplace and in the home. It can also include services such as laundries and kitchens supplying products directly for the patient.

NOTE 1 The method described is intended to determine the activity of commercial formulations or active substances under the conditions in which they are used.

This document specifies a computational method (in line with ISO 17201-4) for estimating the acoustic source data of muzzle blast and explosions on the basis of non-acoustic data for firearms with calibres less than 20 mm and explosions less than 50 g TNT equivalent. This document addresses those cases where no source measurements exist. This document can also be used as an interpolation method between measurements of muzzle blast. Source data are given in terms of spectral angular source energy covering the frequency range from 12,5 Hz to 10 kHz and can be used as data input for sound propagation calculation. This document is not applicable to the prediction of sound levels for the assessment of hearing damage; neither can it be used to predict sound pressure levels nor sound exposure levels at distances where linear acoustics do not apply.

This document provides computational methods for determining the acoustical source level of projectile sound and its one-third octave band spectrum, expressed as the sound exposure level for nominal mid band frequencies from 12,5 Hz to 10 kHz. It also gives a method on how to use this source level to calculate the sound exposure level at a receiver position. Results obtained with the standard can be used as a basis for assessment studies for sound around shooting ranges. Additionally, the data can be used to compare sound emission or immission from different types of ammunition used with the same weapon. The prediction methods apply to outdoor conditions and straight projectile trajectories. Two computational methods are given to determine the acoustical source level: one for streamlined projectile shapes and one for non-streamlined shapes, such as pellets.
