4.6 Urea solution, containing lOg/lot urea (NH2CONH2). buflered to pH 7 by the addiflon of 0.4 g/l of sodium dihydrogen orthophospiiate dihydrate (NaH2PO.’2H20) and 2,5 gfl at disodlum hydrogen orthophosphatc dodecahydrate (Na2IIPO4’12H20), and containIng 0,1 g/l or less of a rapid-wetting surface-active agent, for example, sodium dioctyl sulfosucclnate.
4.7 Test-control fabric
4.7.1 Test-control fabric dyed with Disperse VIolet 1
A woven filament acetate Is uniformly dyed In an open-width dyeing machine with 0,4 % (on mass of fabric) Cl Disperse Violet 1 (Colour Index. Third Edition) in a dye-bath containing 1 gJl of a dispersing agent at a liquor ratio at 10:1.
The fabric construction has both a taffeta and a satin side: (or this test procedure, only the taffeta side will he considered.
The resistance of the test-control fabric to the action of nitric oxide should not be varied between the new lots. The supplier should confirm the performance of the new lot J
4.72 Test-control fabric dyed with Disperse Blue 56
A woven filament acetate Is uniformly dyed in an open-width dyeing machine with 0,8 % (on bass of fabric) Cl Disperse Blue 56 (Colour Index, Third Edition) In a dye-bath Containing 0,5 mI/I of a dispersing agent at a liquor ratio of 42:1.
The fabric construction has both a taffeta and a satin side: lot this test procedure, only the taffeta side will be considered,
The resistance of the test-control fabric to the action ol nitric oxide should not be varied between the new lots. The supplier should confirm the performance of the new loiZI
48 Standard of fading
4.81 Standard fading fabric for test-control fabric dyed with Disperse Violet 1
The rego nerated cellulose woven taffeta is a fabric of similar appearance to the test-control fabric (42.1). dyed to match an average of faded test-control fabric,’1
4.8.2 Standard of lading for test-control fabric dyed with Disperse Blue 56
It Is considered that the standard of lading is completed when a faded test•cantrol fabric (422) is observed to have a contrast equal to grade 3-4 on the grey scale.
4.9 SyrInge, for injecting oxide into the exposure chamber (LI)A medical syringe is best suited to the inietrtinn olthe nitric ucide. Far a larger espusure chamber, the
gas can also be measured and transferred from the nitric oxide reservoir to the exposure chamber by means of a gas burette.
