INTRODUCTION
Add at the end of the first paragraph, the following new dashed item:
– Part 3: Measurement of low level of halogen content by ion chromatography

5.4 Combustion boats
In the last paragraph, replace the sentence “The combustion boat shall then be weighed to an
accuracy of 0,1 mg” with the following new text:
The combustion boat shall then be weighed with an analytical balance in mg, rounded to one
decimal figure, with an accuracy as described in 5.7.

5.6 Air supply system
Replace the second and third paragraphs, including the NOTE with the following:
2 -3
The flow rate of air, ρ, shall be 20 m/h × (π/4) x D x 10 with a tolerance of ±10 %, where D
is the internal diameter of the quartz tube.

© IEC 2019
EXAMPLE
2 -3
If D = 30 mm, 20 m/h × (π/4) × D x 10 = 14,1 l/h, and the flow rate can be in the range 12,7 l/h to 15,5 l/h.
2 -3
If D = 46 mm, 20 m/h × (π/4) × D x 10 = 33,2 l/h, and the flow rate can be in the range 29,9 l/h to 36,5 l/h.
NOTE The flow rate of air, ρ, is related to the velocity, v, according to the formula
π D²
−3
ρ=v ××10
where
D is the internal diameter of the tube (mm);
ρ is the flow rate of air (l/h);
v  is the speed of air (m/h).
2 -3
If v = 20 m/h, this becomes, ρ = 15,7 m/h × D x 10 .
Replace under Method 2 the second sentence with the following:
The air shall be filtered and dried and shall be introduced on the inlet side of the quartz glass
tube (see Figure 4).
