EN 13592:2017 (E) 4 1 Scope This European Standard specifies the general characteristics, test methods and requirements for sacks, bags and bin liners, made from plastic films, used for household waste collection, or household selective waste collection including the collection of biodegradable waste for organic recycling (biodegradation and composting). For the purpose of this European Standard biodegradable and compostable sacks, including ties if any, are those which comply with EN 13432. This European Standard applies only to sacks, bags and bin liners for which the first use is for household waste collection or household selective waste collection. This European Standard does not apply to sacks used to protect bins and that are not lifted at the emptying operation and thus do not require the same mechanical characteristics. NOTE For editorial reasons, in this document the terms “sack” and “bag” are synonymous. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

The test temperature shall be recorded. 7.2.2 Dimensions 7.2.2.1 Apparatus 7.2.2.1.1 Rule, capable of measuring to an accuracy of 1 mm. 7.2.2.1.2 Thickness measuring device, as specified in ISO 4593 with an accuracy of 1 µm. 7.2.2.1.3 Balance, capable of measuring to an accuracy of 0,01 g. 7.2.2.2 Useful length When the sack is laid flat, measure internally the useful length L along the two edges from the top (opening) of the sack to the bottom seam, or to the bottom of the sack for sacks without a bottom seam. All the measured values, expressed in millimetres, shall be rounded to the nearest unit. Measured values of 0,5 shall be rounded up to the next greater 1 mm. The useful length L is the arithmetic mean of the two measurements, expressed in millimetres (mm). The useful length L of the different types of sacks is shown in Figure A.1. Repeat the procedure for each sack. 7.2.2.3 Useful width For sacks with gussets, cut the bottom seam and unfold the gussets. When the sack is laid flat, measure the useful width P at mid-length between the top and the bottom of the sack. In the case of sacks with edge seams, the useful width shall be measured between the inner sides of the seams. The useful width P of the different types of sacks is shown in Figure A.1. All the measured values, expressed in millimetres, shall be rounded to the nearest unit. Measured values of 0,5 shall be rounded up to the next greater 1 mm.

EN 13592:2017 (E) 11 7.2.3.2 Thickness measuring device method This test shall be performed using 10 strips, 100 mm to 120 mm wide, cut from each of the ten sacks from Group I. Whatever the type of sack, the strips shall be cut with their length perpendicular to the direction of extrusion (see Annex A): a) for sacks with bottom seam, cut the strips at mid-length all the way round the sacks; b) for sacks without bottom seam, cut the strips at mid-width all the way round of the extruded film which means from the top to bottom of the two sides of the sack. Keep the remaining parts of these sacks for the measurement of the opacity. By using the thickness measuring device, measure the thickness along the strip, the spacing between two measurements being approximately 30 mm and record each individual measurement. Repeat the procedure for each sack.
7.2.3.3 Gravimetric method Cut out one strip of (100 ± 0,5) mm width from each of the five sacks from Group V, in the transversal
direction and in the middle of the sack. Measure the length li of each strip by using the rule. Calculate the total length of the five strips, lt. Weigh together the five strips pt with the balance. Calculate the average value of the film thickness, t, by using the following formula: ttpltρ××=0001,01 where t is the average film thickness, in micrometres; lt is the total length of the five strips, in millimetres; pt is the weight
of the five strips, in grams;
is the density of the film material, expressed in grams per cubic centimetres. SIST EN 13592:2017

The illuminance shall be measured by using the apparatus defined in 7.2.4.1.2. 7.2.4.1.2 Apparatus 7.2.4.1.2.1 Reference apparatus The apparatus, shown in Figure 1a) consists of: a) a matt black base plate supporting a photoelectric cell, with a surface over which the test specimen can be placed; b) a light source, with a spectrum as close as possible to that of white light, adjustable to a reading of 1 000 lx on the photoelectric cell. The photoelectric cell is positioned at a distance of (3 ± 0,5) cm from the surface of the test strip and a matt black diaphragm of (1 ± 0,1) cm diameter is placed on the photo-electric cell. The characteristics of the photoelectric cell shall be as follows: c) type: siliceous photo-electric cell; d) bias error: 3 %; e) relative spectral response, V, with a maximum deviation of 10 % from the curve related to the photonic brightness. The illuminance of the ambient light, without test specimen and the light source not activated, shall be less than 10 lx. 7.2.4.1.2.2 Other apparatus Testing may also be carried out by using the following apparatus (see Figure 1b)) consisting of: a) a matt black base plate holding a 60 mm minimum diameter photo-electric cell, with a surface over which the test sample can be placed; b) a light source, with a spectrum as close as possible to that of white light, adjustable to a reading of 1 000 lx on the photoelectric cell.

Turn on the light source and wait 5 min for the stabilization of the light. Set up the light, using the variable power supply, to an illuminance, as measured by the photo electric cell, such that lo = 1 000 lx. Place the test specimen with the inner side of the sack on the cell and record the illuminance of the transmitted light, l1, looking for: a) for household waste collection and pre-collection sacks, the lowest value over the entire area of the test specimen; b) for household selective waste collection sacks, the highest value over the entire area of the test specimen. Express the result as a percentage, rounded to the nearest integer. For example, for a value of 38,5 %, the result is 39 %. Repeat the procedure for each sack. SIST EN 13592:2017

Pour into a sack 2 l, 3 l or 6 l of water, as applicable (see Table 1). Hang up the sack by the top to the support and monitor the sack for 5 min, for any evidence of leak. If a drop leaks within these 5 min, start counting the number of drops, n, escaping from the sack during 1 min: a) If n is less than or equal to 20, the sack is declared “conform”; b) If n is greater than 20, proceed with the second step, using the same sack. Prepare 2 l, 3 l or 6 l, as applicable (see Table 1) of the wet mixture, as defined in 7.2.5.1.3. Pour the volume of the wet mixture in the sack. Hang up the sack by the top to the support and monitor the sack for 5 min, for any evidence of leak. Count the number of drops, n, if any, escaping from the sack during 1 min. If n is less than or equal to 20, the sack passes is declared “conform”. If n is greater than 20 or if all water escaped during the first 5 min, the sack is declared “non-conform”.

Sacks, loaded with specified test loads according to the dimensions of the sacks, are dropped from a height of (1,20 ± 0,01) m on a flat and smooth surface. Then the sacks are inspected. 7.2.6.2 Apparatus 7.2.6.2.1 Drop testing machine The drop test machine shall be as specified in EN 22248 and EN ISO 7965-2. 7.2.6.2.2 Test load (ballast) The test load (ballast) consisting of a specified number of cotton or jute bags, filled with PE low density granules for a total mass of (500 +10,0)g each and, if needed, one bag filled with PE low density granules for a total mass of (250 +10,0) g. The cotton or jute bags shall be closed by stitching them across their entire width, at least 40 mm from their opening. Dimensions of the bags up to the stitching are: (180 ± 10) mm x (280 ± 10) mm. The number of bags and test loads according to the dimensions of the sacks are given in Table 2. When P and L are not in the same row in Table 2, the test load to be applied shall be the mean value of the test loads required for the corresponding P and L.
