Relative error tolerance limits at other volume settings can be calculated by dividing the absolute tolerance limit (see Table 1 or Note b) by the set point volume. Multiply the result by 100 to convert it to a percentage.
In this manner, what does tolerance mean in glassware?
Tolerance is the permissible deviation from a specified value. All volumetric glassware has some tolerance for accuracy – that is, all glassware contains or delivers volumes that can be slightly different from the stated volume that is printed on the glassware. … Class A glassware is more accurate that Class B.
Likewise, people ask, what is the tolerance NA 100 ml volumetric flask?
100ml Volumetric Flasks with Snap Caps, 0.08 tolerance. These flasks are manufactured in accordance to DIN ISO 1042 standard. All flasks are calibrated to contain (TC/In) at a +20 °C reference temperature.
What is the tolerance of a 10 mL graduated cylinder?
What is the tolerance of a 25 mL Buret?
