The characteristics, recommended values and test
28、 methods are stated in Table 1. Subsidiary characteristics are stated in Table 2. 5 Sampling If the leather piece available for testing is a whole hide or skin then the test specimens shall be sampled in accordance with standard procedures given in EN ISO 2418. If sampling in accordance with EN ISO
29、2418 is not possible (e.g. leathers are from finished products) details about the sampling shall be given in the test report. 6 Conditioning and sampling preparation Leather samples shall be conditioned and prepared for physical, mechanical and fastness tests in accordance with the reference standar
30、d atmosphere specified in EN ISO 2419. Leather samples for chemical tests shall be conditioned and prepared in accordance with EN ISO 4044. 7 Fundamental and complementary characteristics, test methods and recommended values All the fundamental characteristics indicated in Table 1 shall be taken int
31、o account. The complementary characteristics stated in Table 2 shall be agreed by the parties according to the intended end use of the leather. Whilst the values in Tables 1 and 2 are typical of those expected, it is advisable to issue appropriate guidance with upholstered furniture to inform consum
32、ers of likely performance as well as in service care and maintenance instructions in order to avoid unnecessary problems.
