35、intended for human consumption. Limits are given for impurities commonly present in the product. Depending on the raw material and the manufacturing process other impurities may be present and, if so, this shall be notified to the user and when necessary to relevant authorities. Users of this produc

36、t should check the national regulations in order to clarify whether it is of appropriate purity for treatment of water intended for human consumption, taking into account raw water quality, required dosage, contents of other impurities and additives used in the product not stated in the product stan

37、dard. Limits have been given for impurities and chemicals parameters where these are likely to be present in significant quantities from the current production process and raw materials. If the production process or raw materials leads to significant quantities of impurities, by-products or additive

38、s being present, this shall be notified to the user. 4.2 Composition of commercial product The product shall contain a minimum mass fraction of 80 percent acetic acid. NOTE The commercial product may contain up to a mass fraction of 20 % water. 4.3 Impurities and main by-products The product shall c

39、onform to the requirements specified in Table 2.

40、d in the EU Directive 98/83/EC of 3 November 1998 (see 2). The content of chemical parameters shall conform to the requirements specified in Table 3. Table 3 Chemical parameters Parameter Limit in mg/kg of pure acetic acid Arsenic (As) max. 0,5 Cadmium (Cd) max. 0,5 Chromium (Cr) max. 0,5 Mercury (H

Pesticides and polycyclic aromatic hydrocarbons are not by-products of the manufacturing process. 5 Test methods 5.1 Sampling 5.1.1 Relevant Standa

42、rds Observe the general recommendations of ISO 3165 and take account of ISO 6206. 5.1.2 Sampling from drums and bottles 5.1.2.1 General 5.1.2.1.1 Mix the contents of the container to be sampled by shaking the container, by rolling it or by rocking it from side to side, taking care not to damage the

43、container or spill any of the liquid. 5.1.2.1.2 If the design of the container is such (for example, a narrow-necked bottle) that it is impracticable to use a sampling implement, take a sample by pouring after the contents have been thoroughly mixed. Otherwise, proceed as described in 5.1.2.1.3. 5.1

44、.2.1.3 Examine the surface of the liquid. If there are signs of surface contamination, take samples from the surface as described in 5.1.2.2; otherwise, take samples as described in 5.1.2.3. BS EN 13194:2015EN 13194:2015 (E) 10 5.1.2.2 Surface sampling Take a sample using a suitable ladle. Lower the

45、 ladle into the liquid until the rim is just below the surface, so that the surface layer runs into it. Withdraw the ladle just before it fills completely and allow any liquid adhering to the ladle to drain off. If necessary, repeat this operation so that, when the other selected containers have bee

46、n sampled in a similar manner, the total volume of sample required for subsequent analysis is obtained. 5.1.2.3 Bottom sampling Take a sample using an open sampling tube, or a bottom-valve sampling tube, suited to the size of container and the viscosity of the liquid. When using an open sampling tub

47、e, close it at the top and then lower the bottom end to the bottom of the container. Open the tube and move it rapidly so that the bottom of the tube traverses the bottom of the container before the tube is filled. Close the tube, withdraw it from the container and allow any liquid adhering to the o

48、utside of the tube to drain off. When using a bottom-valve sampling tube, close the valve before lowering the tube into the container and then proceed in a similar manner to that when using an open sampling tube. 5.1.3 Sampling from tanks and tankers From each access point, take samples as follows:

49、a) from the surface of the liquid, using a ladle as described in 5.1.2.2; b) from the bottom of the tank or tanker, using a sampling tube as described in 5.1.2.3 or using a specially designed bottom-sampling apparatus; c) from one or more positions, depending on the overall depth, between the bottom and the surface using a weighted sampling can. 5.2 Analysis 5.2.1 Acetic acid (main product) 5.2.1.1 Principle An accurately weighed quantity of the sample is diluted with water and then titrated with a standard volumetric sodiu
