Dutch test

Europe s controversy over soft PVC toys looks set to continue after EU health experts rejected the best available method for assessing the dangers to children. The so-called Dutch migration test was designed to mimic the way phthalate softeners leak out of PVC when it is sucked or chewed. Manufacturers had hoped the EU s Scientific Committee for Toxicity, Ecotoxicity and the Environment would accept the method as a standard test for phthalate migration, allowing it to be used across the EU, but the committee ruled that the Dutch test was unreliable. It also rejected a similar test developed in the UK, and issued a list of changes that would have to be made before either...

In April 1988, the new kidney Dutch test (NKDT) replaced the Micrococcus (formerly Sarcina ) luteus kidney test. The NKDT is an one-plate test based on examination of the urine present in the renal pelvis by means of paper discs inserted in the renal pelvis (104). The test organism is Bacillus subtilis BGA and incubation is performed for 13-18 h at 37 C. The kidney is incised, and four paper discs are inserted and left there for 30 min. Two paper disks are placed diagonally on the surface of the test plate, and three control disks containing 0.5 g oxytetracycline, 0.05 g sulfamethazine, and 0.5 g tylosin are also placed in the middle of the plate. If both sample inhibition diameters are equal to or...

In a 15-yeai old single base powder Brook e a , [16] found 0.77% DPA, 0.23% A -nitroso-DPA, 0.02% 2-nilro and 0.04% 4-nitrodiphcnylaminc. Similar products in much the same quantities were found in nitrocellulose powder subjected to heating at lOS C (Dutch Test) for ca. 24 hours and at 65.5 ( (NATO Test) for ca. 24 days.

It is described in the Dutch test method that a first identification of the additives can be performed by determination of the gas-chromatographic retention times. Therefore we provide the retention times of the additives which could be analysed by GC. The GC analysis was carried out on a Perkin Elmer autosystera XL with the following conditions. The column was a Hewlett Packard Ultra 1 column. 50 m x 0.32 mm with a film thickness of 0.52 fim of crosslinked methylsiloxane. The temperature program was 5 min at SO C then raised at 5 C/min to 320"C and held for 26 min. The carrier gas was helium at 3.5 mL/min. The temperature of the injector was 260 C and injections of I firL of substance dissolved in dlethylether were injected splitless. The flame ionisation detector used was held at 325 C. Under these conditions the retention times of the hydrocarbon markers were 20.1, 38.5 and 45.2 min for C12, C20 and C24 respectively. Retention indexes of the reference substances can be calculated on basis of these retention times [12J.
