Foodstuffs - Determination of benzene in soft drinks, other beverages and vegetable-based infant foods by headspace gas chromatography mass spectrometry (HS-GC-MS)
SIST EN 16857:2017

This European Standard specifies a method for the determination of benzene in soft drinks, other beverages and vegetable-based infant foods, by headspace gas chromatography mass spectrometry (HS-GC-MS). The method has been validated in an interlaboratory study via the analysis of spiked samples of carbonated soft drink, still fruit-based drink, carbonated fruit-based drink, vegetable and fruit juice containing carrot, infant food vegetable based and infant food containing meat, ranging from 1,9 µg/kg to 18,6 µg/kg. However, linearity of the instrument response was proven for the concentration range from 0,5 µg/kg to 20 µg/kg. The limit of quantification (LOQ) depends on the instrument but can generally be expected to be in the range from 0,5 µg/kg to 1,0 µg/kg.

Foodstuffs - Determination of patulin in fruit juice and fruit based purée for infants and young children - HPLC method with liquid/liquid partition cleanup and solid phase extraction and UV detection
SIST EN 15890:2011

This European Standard specifies a method for the determination of patulin in fruit juices and fruit-based purée, such as baby food purée, using high performance liquid chromatography with ultra-violet detection (HPLC-UV). Using naturally contaminated and spiked samples this method has been validated for the determination of patulin in apple juice, at levels ranging from 3,0 μg/kg to 15,5 μg/kg, and in fruit-based baby food purée, at levels ranging from 3,4 μg/kg to 17,9 μg/kg. Baby food fruit purée (commercially available on the European market) used in this study contained the following ingredients: blueberry; apple; banana; lemon; wheat biscuits; wheat syrup; whole milk; and vegetable oil. A detailed listing, including the fractions, of each product used in this study is given in [1].
Further information on validation, see Clause 9 and Annex B.

Electronic invoicing - Part 8: Semantic data model of the elements of an e-receipt or a simplified electronic invoice
kSIST FprEN 16931-8:2024

This document establishes a semantic data model of an e-receipt or a simplified electronic invoice.
NOTE   In the remainder of this document, when “e-receipt” is mentioned, “simplified invoice” is also meant.
The semantic model includes essential information elements that an electronic receipt needs to ensure legal (including fiscal) compliance and to enable interoperability for cross-border, cross sector and domestic trade. The semantic model can be used by organizations in the private and the public sector for documenting by issuing a receipt for the purchase of services and /or goods. It can also be used for documenting a purchase between private sector enterprises. In addition, it has been designed for the use of consumers.

Railway applications - Acoustics - Measurement of source terms for environmental noise calculations
SIST EN 17936:2024

This document addresses the measurement of source terms for environmental noise calculation for rail traffic (including light rail, such as trams, metros, etc.). It is applicable to the measurement of in-service trains on operational tracks.
It is not applicable to type acceptance testing of rolling-stock or tracks, or to derive source terms for time domain models.
The following rail traffic noise source types are in the scope:
-   rolling noise;
-   traction and equipment noise;
-   aerodynamic noise;
-   impact noise (e.g. rail joints, switch and crossings, wheel flats);
-   braking noise;
-   bridge noise;
-   squeal noise.
Noise from rail vehicles at standstill, such as stationary engine idling and auxiliary equipment at yards and stations, is covered by EN ISO 3095:2013 for measurement procedures and operating conditions, and by EN ISO 3740:2019 and EN ISO 3744 for the determination of sound power. It is therefore not in the scope of this document.
The calculation of the propagation of sound is part of generally standardized propagation models which are not addressed in this document.
Noise from fixed installations (e.g. stations, depots, electricity sub-stations) is not in the scope of this document.
Source terms are specific to a vehicle and track type. The scope includes measurement procedures and conditions and sampling requirements.
