13、 supersedes CEN/TS 14999:2006. CEN/TS 14999:2013 includes the following significant technical changes with respect to CEN/TS 14999:2006: Inclusion of environmental and safety statements on the foreword; Modification of title to be in line with the scope; New explanatory note added to the scope; Defi
14、nition of the RH on standard conditions; Minor changes on the procedure. SAFETY PRECAUTIONS Persons using this document should be familiar with the normal laboratory practice, if applicable. This document does not purport to address all of the safety problems, if any, associated with its use. It is
15、the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any regulatory conditions. ENVIRONMENTAL PRECAUTIONS It is understood that some of the material permitted in this standard may have negative environmental impact. As technological advant
16、ages lead to acceptable alternatives for these materials, they will be eliminated from this standard to the extent possible. At the end of the test, the user of the standard should take care to carry out an appropriate disposal of the wastes, according to local regulations. According to the CEN-CENE
17、LEC Internal Regulations, the national standards organisations of the following countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungar
18、y, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. PD CEN/TS 14999:2013CEN/TS 14999:2013 (E) 4 1 Scope This Technical Specification describes a method for an
19、accelerated ageing test of an adhesive in its container. The result provides the manufacturer with an indication of the storage stability of the adhesive and container combination and their ability to retain adhesive properties. The method described is intended for solvent based adhesives for thermo
20、plastic piping systems but may be applied to other adhesive types if appropriate. The method described in this Technical Specification does not give a correlation between the results obtained after the accelerated ageing test and after the shelf life of the adhesive at the ambient conditions defined
21、 by the manufacturer in the data sheet. NOTE Some of the solvents used in adhesives applied for bonding pipe joints are highly flammable and may even cause explosion when heated (tetrahydrofurane). Therefore, the users of this standard need to take special precautions when testing such adhesives acc
22、ording to the provisions of this standard which require prolonged heating of the container with the adhesive. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edi
23、tion cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

25、r strength (ISO 9311-2) 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 923:2005+A1:2008 apply. 4 Principe The sample is subjected to a combination of temperature and time under specified conditions, followed by comparison of the viscosity and the she
26、ar strength of the adhesive bond made with the aged sample with those of a reference sample that has been maintained under standard reference conditions; i.e. (23 2) C. 5 Apparatus 5.1 Oven, able to maintain a temperature of (50 2) C or (40 2) C. PD CEN/TS 14999:2013CEN/TS 14999:2013 (E) 5 5.2 Clima
27、tic chamber, able to maintain the conditions to (23 2) C. 6 Sampling Take a minimum of six identical unopened containers of each adhesive, three to be exposed to the ageing conditions and three as reference sample. Typical examples of containers commonly used for adhesives for thermoplastic piping s
28、ystems, though not exhaustive, are: a) tin plated can + tin plated cap; b) tin plated can + plastic cap; c) aluminium plated can + plastic cap; d) brown glass bottle + plastic cap; e) plastic container + plastic cap. 7 Procedure Put the three samples of the adhesive in an oven (5.1) for 28 days at (
29、50 2) C. Depending on the character of the adhesive, lower temperatures may be used, e.g. (40 2) C for three months. At the end of the test period, condition the aged samples for 24 h at (23 2) C in the climatic chamber (5.2). Put the reference sample in a climatic chamber at (23 2) C for 24 h. Dete
30、rmine the viscosity in accordance with EN 12092, film properties in accordance with EN ISO 9311-1 and the shear strength at 24 h setting time in accordance with EN ISO 9311-2 for all the samples (aged and reference samples). Calculate the average value of the viscosity, film properties and shear str
31、ength of the adhesive bonds made with all the samples. The average value of the viscosity, film properties and the shear strength of the adhesive bonds made with the aged samples compared to those of the reference samples gives an indication of the storage stability of the adhesive and container com
32、bination and their ability to retain adhesive properties. The average value for viscosity and film properties for the aged samples shall conform to the manufacturers specifications for application properties. The average value for the shear strength at 24 h for the adhesive bonds made with the aged
33、samples shall meet the requirements in the system standards (EN 14680 or EN 14814, depending on the type of adhesive). NOTE Following the weight loss and viscosity on the aged samples can help in understanding the behaviour of each adhesive and container couple. 8 Test Report The test report shall i
34、nclude, at least, the following information: a) a reference to this Technical Specification (i.e. CEN/TS 14999:2013); PD CEN/TS 14999:2013CEN/TS 14999:2013 (E) 6 b) type and identification (batch number, date of manufacturing or other code) of the adhesive tested; c) description of the packaging tes
35、ted; d) the average viscosity value of the three aged samples and that of the three reference samples; e) the average film properties value for the aged samples and the reference samples; f) the shear strength obtained for the adhesive bonds made with the aged samples and the reference samples; g) a
36、ny modification of the procedures described, and any incident which may have affected the results; h) observations of the visual appearance of the containers and the adhesive after aging; i) date of the test.
