This document specifies test methods for the determination of the chemical compatibility of packaging/ IBC made from polyethylene (PE), fluorinated polyethylene and co-extruded plastics. It covers the determination of adequate plastics compatibility against the following processes of deterioration:
—     softening due to absorption (swelling);
—     stress cracking;
—     combinations thereof.
This document is applicable to:
—     drums and jerricans made from plastics;
—     composite packaging (plastics) with inner receptacle made from plastics;
—     rigid plastics IBCs (types 31H1 and 31H2);

—    ethylene vinyl alcohol (EVOH), bonding agents, PE.
Note              Packaging and IBCs made from PE and packaging and IBCs made from PE with fluorinated internal surfaces, deteriorate additionally due to molecular degradation reactions with the corresponding packaged substances. For this, the chemical compatibility can also be verified by the type tests described in ISO 13274:2013, Annex B, B.2.3, using the standard liquid nitric acid (55 %) or appropriate original packaged substances. Packaging made from Coex PE/PA and Coex PE/EVOH is not resistant to polar acid molecularly degrading substances such as nitric acid, with the result that a corresponding method is not considered for this process of deterioration in this document.

This document specifies methods for the determination of five selected estrogens in whole water samples listed in Table 1 (see Clause 4). The methods are based on solid-phase extraction (SPE; disk or cartridge) followed by liquid or gas chromatography-mass spectrometry detection (tandem mass spectrometry or high resolution mass spectrometry). Depending on the sample preparation chosen, the sample preparation can be applicable to the analysis of selected estrogens in drinking water, groundwater and surface water containing suspended particulate matter (SPM) up to 500 mg/l, dissolved organic carbon (DOC) content up to 14 mg/l (whole water samples).
The lower application range defined as verified limit of quantification can vary depending on the methods, the sensitivity of the equipment used and the matrix of the sample. The range is 0,006 ng/l to 1 ng/l for 17alpha-ethinylestradiol (EE2) and 0,038 ng/l to 1 ng/l for the other estrogens in drinking water, ground water and surface water. The upper limit of the working range is approximately tens of nanograms per litre.
For application that targets the measurements of very low level concentrations (between the lowest LOQ and 0,1 ng/l), every single step of the procedure becomes critical.
The methods can be used to determine further estrogens or hormones in other types of water, for example treated wastewater, if accuracy has been tested and verified for each case as well as storage conditions of both samples and reference solutions have been validated.

For some of these processes, practical experience has been gained over many years, so a basic knowledge base for the development of a guideline is already available.
At the same time, it is important to also take into account future-oriented processes, for which at the moment little but increasing experience is available or which have so far only been implemented on a small scale.

—     Method 2 which assesses the quality of sealed anodic oxidation coatings by measuring the loss of mass after immersion in a phosphoric acid based solution with prior acid treatment.
Method 1 is applicable to anodic oxidation coatings intended for decorative or protective purposes or where resistance to staining is important.
Method 2 is applicable to anodic oxidation coatings intended for outdoor architectural purposes. For less severe applications, Method 1 can be more suitable.
The methods are not applicable to the following:
—     hard-type anodic oxidation coatings which normally are not sealed;
—     anodic oxidation coatings that have been sealed only in dichromate solutions;
—     anodic oxidation coatings produced in chromic acid solutions;
—     anodic oxidation coatings that have undergone treatment to render them hydrophobic.
NOTE 1        While the methods assess the quality of hydrothermal sealing applied to anodized aluminium, they can be appropriate for other sealing methods.
NOTE 2        The methods are destructive and can serve as reference methods in case of doubt or dispute regarding the results of the test for loss of absorptive power (see ISO 2143) or the measurement of admittance (see ISO 2931).

This document specifies a procedure for the analysis of residues of highly polar pesticides and metabolites, which are not amenable to common multiresidue methods, in various food commodities of plant and animal origin, including fruits, vegetables, cereals, pulses, oily seeds, nuts, milk, liver and honey. The method was developed at the EURL-SRM hosted at CVUA Stuttgart [1], [2], [3] and has been collaboratively studied on a large number of commodity/pesticide combinations. Guidelines for calibration are outlined in CEN/TS 17061:2019.
