¹ Tests de­signed to de­term­ine the prop­er­ties of sub­stances and pre­par­a­tions must be car­ried out in ac­cord­ance with the test meth­ods spe­cified in the tech­nic­al pro­vi­sions re­ferred to in An­nex 2 num­ber 2.

² Oth­er test meth­ods may be used if:

a.

no meth­od is spe­cified in ac­cord­ance with para­graph 1;

b.

the man­u­fac­turer can show that a spe­cified meth­od is not suit­able for the de­term­in­a­tion of a giv­en physi­co­chem­ic­al prop­erty; or

c.

the meth­od is re­cog­nised in the EU in ac­cord­ance with Art­icle 13 para­graph 3 of the REACH Reg­u­la­tion⁷⁷.

³ If oth­er test meth­ods are used, the man­u­fac­turer must show that they:

a.

pro­duce val­id res­ults; and

b.

take due ac­count of an­im­al pro­tec­tion in the case of tests on an­im­als.

⁴ Non-clin­ic­al tests de­signed to de­term­ine prop­er­ties dan­ger­ous to health or the en­vir­on­ment must be car­ried out in ac­cord­ance with the prin­ciples of Good Labor­at­ory Prac­tice (GLP) spe­cified in the Or­din­ance of 18 May 2005⁷⁸ on Good Labor­at­ory Prac­tice.

⁵ If cer­tain tests do not, or do not fully, com­ply with GLP prin­ciples, the per­son sub­mit­ting the test re­ports must state the reas­ons. The No­ti­fic­a­tion Au­thor­ity, in con­sulta­tion with the as­sess­ment au­thor­it­ies, shall de­cide wheth­er to ac­cept these test res­ults.
