kSIST-TS FprCEN ISO/TS 16486-7:2023

This document gives guidance and requirements for the assessment of conformity of compounds, products, joints and assemblies in accordance with the applicable part(s) of the ISO 16486 series which are intended to be included in the manufacturer’s quality plan as part of the quality management system and for the establishment of certification procedures.
NOTE 1    A basic test matrix in Annex B provides an overview of the testing scheme.
It is recommended for the manufacturer to have a management system such as ISO 9001[4] or equivalent.
NOTE 2    If certification is involved, certification bodies and inspection bodies operating according to ISO/IEC 17065 and ISO/IEC 17020 are considered to be competent.
In conjunction with the other parts of the ISO 16486 series (see Clause 2), this document is applicable to unplasticized polyamide (PA-U) piping systems intended to be buried and used for the supply of gaseous fuels. It is applicable to PA-U pipes, fittings and valves, as well as to their joints and to joints with components of other materials intended to be used under the following conditions:
a)    a maximum operating pressure (MOP) up to and including 18 bar[1] (the MOP is limited to 16 bar for CEN member countries, where ISO 16486-6 is replaced by CEN/TS 12007-6[1]);
b)    an operating temperature of 20 °C as the reference temperature.
NOTE 3    For operating temperatures different to 20 °C, derating coefficients can be used (see ISO 16486-6). CEN member countries use CEN/TS 12007-6[1] and ISO/TS 16486-7 (this document) as a basis, but they can also request additional requirements. For non-CEN member countries, information for dealing with special cases for PA-U can be found in ISO/TS 16486-7 (this document) and PPI TR-3.[7]
For mechanical fittings conforming to ISO 17885, guidance for assessment of conformity is not given in this document. When requested, a quality plan based on the tests mentioned can be set up in agreement between user and manufacturer.
The ISO 16486 series covers a range of maximum operating pressures and gives requirements concerning colours.
NOTE 4    It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.
[1] 1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2.

kSIST FprEN 1915-1:2023

This document applies to GSE when used in civil air transport as intended by the manufacturer and contains safety requirements relating to the equipment in general.
This document specifies the technical requirements to minimise the hazards listed in Clause 4 which can arise during the commissioning, operation and maintenance of GSE when used as intended including any reasonably foreseeable misuse by the manufacturer, when carried out in accordance with the specifications given by the manufacturer or his authorised representative. It also takes into account some requirements recognised as essential by authorities, aircraft and ground support equipment (GSE) manufacturers as well as airlines and handling agencies.
This part of EN 1915 is intended to be used in conjunction with EN 1915-2:2001+A1:2009, EN 1915-3:2004+A1:2009 (for self-propelled GSE) and EN 1915-4:2004+A1:2009, and with the relevant part of EN 12312 to give the requirements for the types of GSE within the scope of EN 12312.
When EN 12312 does not contain a relevant part for a GSE, EN 1915 (all parts) gives general requirements that may apply, although additional machine specific requirements, to be determined by the manufacturer, are likely to be required.
This part of EN 1915 does not apply to automotive parts approved for public vehicles in the EU and EFTA, when used on GSE for the purpose for which they are designed.
This part of EN 1915 does not establish additional requirements for the following:
a)   operation elsewhere than in an airport environment;
b)   operation in severe conditions, e.g. ambient temperature below -20 °C or over 50 °C, tropical or saturated salty atmospheric environment, strong magnetic or radiation field;
c)   operation subject to special rules, e.g. potentially explosive atmosphere except as regards operation in the vicinity of an aircraft fuel tank during fuelling operation;
d)   hazards caused by power supply other than from electrical networks;
e)   hazards occurring during construction, transportation, decommissioning and disassembly of the GSE;
f)   hazards caused by wind velocity in excess of the figures given in this document;
g)   direct contact with food stuffs;
h)   earthquake, flood, landslide, lightning and more generally any exceptional natural event;
i)   electromagnetic compatibility (EMC);
j)   hazards caused by noise and vibration, see EN 1915-3:2004+A1:2009 and EN 1915-4:2004+A1:2009.
While this standard gives some basic requirements for wireless remote controls, additional requirements will be necessary.
This part of EN 1915 is not applicable to GSE which are manufactured before the date of publication by CEN of this document.

Determination of the characteristic limits (decision threshold, detection limit and limits of the coverage interval) for measurements of ionizing radiation - Fundamentals and application - Part 4: Guidelines to applications (ISO 11929-4:2022)
oSIST prEN ISO 11929-4:2023

This document specifies a procedure, in the field of ionizing radiation metrology, for the calculation of the “decision threshold”, the “detection limit” and the “limits of the coverage interval” for a non negative ionizing radiation measurand when counting measurements with preselection of time or counts are carried out. The measurand results from a gross count rate and a background count rate as well as from further quantities on the basis of a model of the evaluation. In particular, the measurand can be the net count rate as the difference of the gross count rate and the background count rate, or the net activity of a sample. It can also be influenced by calibration of the measuring system, by sample treatment and by other factors.
ISO 11929-4 gives guidance to the application of ISO 11929 (all parts), summarizing shortly the general procedure and then presenting a wide range of numerical examples. The examples cover elementary applications according to ISO 11929-1 and ISO 11929-2.
