The language, the standards and the history of environmental monitoring in pharmaceutical cleanrooms, one cubic metre (cubic meter) of air at a time.

In each issue, one sentence of a standard: what it means in plain English, and the line to write on the record.

Each issue, three parts

1. 1

   The sentence

   One sentence of a standard, quoted as it is written, with the name of the standard and the year.

2. 2

   What it means

   The same idea in plain words, short enough to be read aloud to an operator.

3. 3

   On the record

   The line to write on the record, taken from the standard that was read.

Each issue is for the person who has to explain that sentence to an operator.
