EN 13832-1:2018 (E) 4 1 Scope This European Standard specifies test methods for the determination of the resistance of footwear against selected chemicals under the following contact situations: splashing, degradation, and permeation. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 16523-1:2015, Determination of material resistance to permeation by chemicals - Part 1: Permeation by liquid chemical under conditions of continuous contact EN ISO 868:2003, Plastics and ebonite - Determination of indentation hardness by means of a durometer (Shore hardness) (ISO 868:2003) EN ISO 20344:2011, Personal protective equipment - Test methods for footwear (ISO 20344:2011) ISO 23529, Rubber - General procedures for preparing and conditioning test pieces for physical test methods 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN ISO 20344:2011 and EN 16523-1 and the following apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses:

IEC Electropedia: available at http://www.electropedia.org/

ISO Online browsing platform: available at http://www.iso.org/obp 3.1 degradation deleterious change in one or more properties of a footwear material due to contact with a chemical Note 1 to entry: These changes may include, e.g. flaking, swelling, disintegration, embrittlement, discoloration, dimensions, appearance, hardening and softening. 3.2 permeation process by which a chemical moves through a footwear material at a molecular level Note 1 to entry: Permeation involves the following: — absorption of molecules of the chemical into the contacted (outside) surface of a material; — diffusion of the absorbed molecules into the material; — desorption of the molecules from the opposite (inside) surface of the material. 3.3 splashing contact after pouring of chemical on the footwear SIST EN 13832-1:2018

EN 13832-1:2018 (E) 5 3.4 test chemical chemical that is used to assess the behaviour of a footwear or a footwear material after a defined contact under the laboratory test conditions Note 1 to entry: The chemical can cause adverse effects to the human body by contact with the skin 4 Test methods 4.1 Sampling and conditioning The minimum number of samples, i.e. separate items of footwear, to be tested in order to verify compliance with the requirements specified in EN ISO 20344:2011, together with the minimum number of test pieces to be taken from each sample, are given in Table 1. Wherever possible, test pieces shall be taken from the whole footwear item unless otherwise stated. If it is not possible to obtain a large enough test piece from the footwear, then a sample of the material from which the component has been manufactured may be used instead and this should be noted in the test report. Table 1 — Minimum number of samples and test specimens or test pieces Tests Number of test pieces from each sample Test only on the final footwear Table 1 of EN ISO 20344:2011 is applicable

Splashing test (4.2) 1 pair of shoe (the medium size of the range) per chemical yes Degradation test (4.3)

2 discs for outsole (one before and one after degradation)

2 discs for upper (one before and one after degradation) If possible Permeation test (4.4) 3 discs

per chemical yes All test pieces shall be conditioned in a standard atmosphere of (23 ± 2) °C and (50 ± 5) % relative humidity for a minimum of 24 h before testing, unless otherwise stated in the test method. The maximum time which shall elapse between removal from the conditioning atmosphere and the start of testing shall be not greater than 10 min, unless otherwise stated in the test method. For each of the required measurements performed in accordance with this standard, a corresponding estimate of the uncertainty of measurement should be evaluated. One of the following approaches should be used: — a statistical method, e.g. as given in

ISO 5725-2 [9]; — a mathematical method, e.g. as given in ISO/IEC Guide 98-3 [10]; — uncertainty and conformity assessment as given in ISO/IEC Guide 98-4 [11]; — JCGM 100:2008 [12] SIST EN 13832-1:2018

EN 13832-1:2018 (E) 6 4.2 Splashing test 4.2.1 Principle Whole footwear samples are exposed for several period of time to a limited volume of specific liquids which might be encountered in operational use. Damage to the materials and structure of the footwear including ingress through seams and manufactured structure is assessed at specified step of the test method. 4.2.2 Method A pair of shoes shall be evaluated per chemical to be applied. a) Clean the footwear with a dry absorbent paper to remove any productions residues. b) Lightly mark (a waxed pencil or chalk have been found to be suitable) the sides of the test sample with a horizontal line as defined in Figure 1. The height h is given by Table 10 (Minimum height, below which the requirements of the upper shall be fulfilled) of EN ISO 20345:2011. This is to define the tested area (under this line) to allow accurate application of the test chemical.

Key h height of the tested area 1 Test area Figure 1 — Tested area for the splashing test c) Store the footwear for at least 24 h in an environment at (23 ± 2) °C and (50 ± 5) %rh. The test shall performed between (20 and 25) °C. d) Fill the footwear with absorbent paper as a trace medium for liquid ingress. Ensure the paper is in contact with the seams of the footwear at the front, bellows and lacing in particular. e) Fasten the footwear. f) Prepare a minimum of 130 ml of the chosen test chemical. If several chemicals have to be chosen, it is necessary to use a new pair of footwear for each chemical. SIST EN 13832-1:2018

EN 13832-1:2018 (E) 7 g) Place the footwear into a tray of a sufficient size (30 ± 1cm large 40 ± 1cm long 5 ± 1 cm high) to allow residual liquid to drain from around the footwear during application. The material constituting the tray shall not be affected by the test chemical. Any accidental spillage during application into the inner of the footwear shall be prevented. h) Pour 60 ± 6 ml of test liquid evenly across the two sides and front of the footwear using a (20 ± 2) ml containers. Note 1 to entry: It has been found that using smaller containers each holding (20 ± 2) ml of the test liquid per side and across the centre front makes application more consistent. The footwear shall have an angle of (45 ± 10) degrees when pouring chemicals onto the side sections. Using the 20 ml container, move along the drawn line and wet the test area of the sample. The pouring distance shall be between 4 cm and 6 cm (see Figure 2). Leave any spilled volume in the tray in contact with the outsole until the first examination is completed.

EN 13832-1:2018 (E) 8 l) Remove the absorbent paper from inside the footwear and, if any liquid penetration is visible as damp patches, note the location of ingress. m) 1 h (±2 min) after pouring the chemical, carry out a visual inspection of the two footwear, comparing it to an original (or photographs) and note any damage or visual change as defined in Annex B (for example, surface marking or damage, damage to components, lack of functionality). Check the area under any lacing or fastenings where spilt liquid might be trapped and not easily visible. The test sample shall be cut open to assess any internal damage or wetness. n) 24 h (±30 min) after pouring the chemical, carry out a second visual inspection of the two footwear, comparing it to an original (or photographs) and note any damage or visual change as defined in Annex B. 4.2.3 Test report The test report shall include the following information: a) the number of this European Standard, i.e. EN 13832-1:2018, 4.2; b) a full description of the sample and its origin; c) a full description of the chemicals used in the splashing test; d) the appearance of the test piece after the splashing tests (e.g. cracking, delamination) after 10 min, 1 h after the test and 24h after the test; e) any penetration of chemical inside the footwear; f) any trapped chemical in the footwear (inside or outside); g) any deviation from test methods. 4.3 Degradation test 4.3.1 Principle Some basic physical properties of the footwear component (upper and outsole) are checked before and after contact with chemicals.
