It is the responsibility of the user to establish appropriate safety and health practices and to ensurecompliancewithanynational regulatoryconditions. IMPORTANTIt is absolutely essential that tests conducted according to this standard be carried out by suitably trained staff. Scope 1 This International Standard specifies a method for the determination of selected polybrominated diphenyl ethers (PBDE) (see Figure 1 and Table 1) in sediment and sludge using gas chromatography/mass spectrometry (GC-MS) in the electron impact (El) or negative ion chemical ionization (NCl) mode When using GC-El-MS, the method is applic
