Table 3B — Factor to convert mass (in g) of mercury at t °C
Trang 5Although the cubic centimetre (cm3) is used as the unit of volume throughout this British Standard, many items of volumetric glassware are calibrated in millilitres As the millilitre is commonly used as a special name for the cubic centimetre, in accordance with the International System of Units (SI), this British Standard can also be used to calibrate volumetric glassware when the unit of volume is the millilitre.
The principle difference between BS 1797:1968 and this edition is the use of the kilopascal (kPa) instead of millimetres of mercury (mmHg)1) as the unit of atmospheric pressure
NOTE It is recognized that many perfectly satisfactory barometers are in use which are calibrated
in millimetres of mercury For the convenience of such users the kilopascal values given in the tables have been chosen to correspond (within the accuracy of the corrections):
CAUTIONAttention is drawn to the Health and Safety at Work etc Act, 1974, and in particular the need for ensuring that the method using mercury referred to in this British Standard is carried out with suitable precautions
The procedures described in this standard, especially the one using mercury, are intended to be carried out by qualified chemists or other suitably trained and/or supervised personnel Normal safety precautions should be observed throughout the use of the procedures
Particular attention is drawn to the need to avoid breathing mercury vapour or contact with the eyes and skin
A British Standard does not purport to include all the necessary provisions of a contract Users of British Standards are responsible for their correct application
Compliance with a British Standard does not of itself confer immunity from legal obligations.

This British Standard gives tables and equations
that enable the delivered or contained capacity, in
cubic centimetres, of soda lime and borosilicate
volumetric glassware at 20 °C to be determined at
temperatures between 5 °C and 35 °C, and air
pressures between 98 kPa and 104 kPa2), and when
using either distilled or deionized water complying
with BS 3978, or mercury, for capacities
between 1 cm3 and 2 000 cm3
Table 1 enables the correction of apparent mass of
water for water temperatures between 5 °C
and 35 °C
Table 2 enables the correction of apparent mass of
water for air temperatures between 5 °C and 35 °C,
and air pressures between 98 kPa and 104 kPa
Table 3 enables the conversion of apparent mass of
mercury into capacity at 20 °C for temperatures
between 5 °C and 35 °C
Table 4 enables the determination of apparent mass
of mercury occupied by 1 cm3at 20 °C
Appendix A gives examples of the use of the tables
NOTE The titles of the publications referred to in this standard
are listed on the inside back cover.
WARNING Mercury is toxic by inhalation Danger
of cumulative effects Avoid breathing vapour Avoid
contact with eyes and skin
2 Basis of tables
The tables using water have been computed using
the numerical data and equations in Annex B of
BS 6696:1986
In the case of mercury, the values used are based on
the mean value of 13545.884 kg/m3 at 20 °C
determined by Cook (1961, Phil Trans Roy
Soc A., 254, 125) and the expansion formula of
Beattie et al (1941, Proc Amer Acad Arts
Sci., 71,371)
The coefficient of cubical thermal expansion of glass
(in °C–1× 106) is
27 for soda glass (Table 1A, Table 3A and
Table 4A) and
10 for borosilicate (Table 1B, Table 3B and
Table 4B)
These are values near to the average for the
expansion coefficients of the two types of glass
normally employed with making volumetric
apparatus in the United Kingdom
3.1 General
Two sets of tables are included; one set (A) relates
to vessels made of soda glass and the other set (B)
to vessels made of borosilicate glass
Each set of tables is appropriate to the following operations
a) Table 1A and Table 1B Conversion of the
observed mass, in grams, in air of average density, of the distilled or deionized water contained or delivered by a glass vessel at a known temperature, to the capacity of the vessel
at 20 °C
b) Table 2 Correction for the departure of the
effective air density from the average air density assumed in Table 1A and Table 1B
NOTE The corrections given in Table 2 need only be applied when high accuracy is desired The values given apply to either soda or borosilicate glass.
c) Table 3A and Table 3B Conversion of the
observed mass in air of the mercury contained or delivered by a glass vessel at a known
temperature, to the capacity of the vessel
at 20 °C
d) Table 4A and Table 4B Conversion of the
nominal capacity of a glass vessel at 20 °C, to the mass in air of the mercury contained or delivered
When it is necessary in tropical countries to work at
an ambient temperature considerably above 20 °C, and these countries do not wish to use exclusively the standard reference temperature of 20 °C, it is recommended that they should adopt a temperature
of 27 °C (see BS 5898)
2) 1 kPa = 1 kN/m2= 10 mbar = 7.500 60 mmHg.
Trang 8significant, the capacity of a vessel at 27 °C may be
obtained from its capacity at 20 °C by
adding0.000 19 cm3/cm3 for soda glass
or 0.000 07 cm3/cm3 for borosilicate glass Thus the
correction for a 1 000 cm3 soda glass vessel
is + 0.19 cm3 This correction is, of course, applied
after the capacity at 20 °C has been obtained by the
application of the corrections in Table 1A or
Table 1B, and Table 2, or the factor given in
Table 3A or Table 3B
With regard to Table 4A and Table 4B, the mass of
mercury contained or delivered at t °C by a vessel of
capacity 1 cm3 at 27 °C may be obtained by
subtracting from the tabulated mass of
mercury, 0.003 g for soda glass (see Table 4A)
or 0.001 g for borosilicate glass (see Table 4B)
3.3 Correction for type of glass
If the expansion coefficient of the glass vessel over
the temperature range of 5 °C to 35 °C is known to
differ from that used in the tables and the
temperature of the water is far removed from 20 °C,
it may be necessary, when working to the limit of
accuracy, to make an adjustment A comparison of
the corresponding entries for the appropriate
capacity and temperature in the tables for
borosilicate and soda glass will indicate the effect of
the difference between the cubical expansion
coefficients 0.000 010/°C and 0.000 027/°C If this
shows that an adjustment would be significant, the
correction appropriate to the glass concerned may
be obtained by linear interpolation between the two
entries
tables are directly proportional to capacity (e.g the entries in Table 1A/500 are the same as those in Table 1A/50 with the decimal point moved one place
to the right)
For capacities not listed, appropriate values may therefore be readily calculated from the tables provided For many capacities, this can be done simply by moving the decimal point (e.g values for 0.7 cm3 from Table 1A/7, for 1.5 cm3 fromTable 1A/15, for 800 cm3 from Table 1A/80); for other capacities, interpolation is required
