Materials and articles in contact with foodstuffs - Test methods for translucency of ceramic articles

This European Standard specifies test methods for the determination of the translucency of ceramic articles. Two methods are described: - Method A, a qualitative method for estimating translucency, applicable to ceramic articles within a specified thickness range. - Method B, a quantitative method for the determination of body translucency requiring test specimens to be cut from ceramic articles.

Materials and articles in contact with foodstuffs - Plastics - Part 3: Test methods for overall migration in evaporable simulants
SIST EN 1186-3:2022

This document specifies methods for measuring overall migration of plastic materials and articles intended to come into contact with foodstuffs by contacting test specimens with evaporable food simulants at temperatures greater than or equal to 4 °C and not exceeding the reflux temperature.
The overall migration from a sample of the plastics is determined as the loss in mass of non-volatile substances expressed:
- per unit surface area; or
- per kg of food simulant; or
- per article
after contact with a food simulant under defined conditions.
According to the type of materials or shape of articles, contact with the food simulant is carried out on a single surface (pouch, cell, filling) or by immersion.
This document does not cover the interpretation of the results which is expected to account for regulatory requirements.

This document specifies methods for measuring overall migration of plastic materials and articles intended to come into contact with foodstuffs by contacting test specimens with vegetable oils at temperatures greater than or equal to 4 °C and less than or equal to 175 °C.
NOTE   Some vegetable oils are not suitable for use below 20 °C.
The overall migration from a sample of the plastics is determined as the loss in mass of non-volatile substances expressed:
- per unit surface area; or
- per kg of food simulant; or
- per article
after contact with a food simulant under defined conditions.
According to the type of materials or shape of articles, contact with the food simulant is carried out on a single surface (pouch, cell, filling) or by immersion.

Materials and articles in contact with foodstuffs - Certain epoxy derivatives subject to limitation - Determination of NOGE and its hydroxy and chlorinated derivatives
SIST EN 15137:2006

This European standard describes the determination of NOGE components with more than two aromatic rings (the two-ring NOGE is equal to BFDGE = Bis(2-hydroxyphenyl)methane bis(2,3-epoxypropyl)ether) and at least one epoxy group as well as their derivatives containing chlorohydrin functions and having a molecular mass less than 1000 Daltons in can coatings.
A high performance liquid chromatography (HPLC) method is employed based on reversed phase HPLC and fluorescence detection.
The method is capable of determining NOGE and its derivatives at a minimum level of 1 mg/ml in solution.
Direct HPLC analysis of the can coating extract may result in chromatograms difficult to interpret, due to interference from other components or the instability of the monomer resulting in a complex mixture of derivatives and/or reaction products. By forced hydrolysis of all epoxy groups and their reaction products, the quantification of the NOGE is simplified and the identities of the substances are indicatively confirmed.
NOTE   In this European standard the term “NOGE and its derivatives” refers to the requirements of Directive 2002/16/EC [1]. This includes NOGE components with more than two aromatic rings and at least one epoxy group as well as their derivatives containing chlorohydrin functions and having a molecular mass less than 1000 Daltons.

Materials and articles in contact with foodstuffs - Certain epoxy derivatives subject to limitation - Determination of BADGE, BFDGE and their hydroxy and chlorinated derivatives in food simulants
SIST EN 15136:2006

This European standard describes a method for the determination of BADGE, BFDGE and their reaction products in food simulants: distilled water, 3 % w/v aqueous acetic acid, 10 % v/v aqueous ethanol solution and olive oil or sunflower oil.
A high performance liquid chromatography (HPLC) method is employed based on reversed phase HPLC and fluorescence detection.
The method is capable of determining BADGE and its derivatives at a minimum level of 0,05 µg/ml food simulant.
BFDGE and its derivatives can be determined at a minimum level of 0,1 µg/ml food simulant.
Direct HPLC analysis of the migration solutions may result in chromatograms difficult to interpret, due to interference from other components or the instability of the monomers resulting in a complex mixture of derivatives and/or reaction products. By forced hydrolysis of all epoxy groups and their reaction products, the quantification of the relevant substances is simplified and in addition the identities of the substances are indicatively confirmed.
NOTE   In this European standard the term “BADGE, BFDGE and their derivatives” refers to the substances listed in Directive 2002/16/EC. These substances are listed in 4.1.
