The GPS Pocket Book

Now available in English, Chinese (Mandarin), German and Swedish.

The English version of the GPS Pocketbook is available from Amazon as print-on-demand in a 122mm × 173 mm format.

The other versions are available from our store in A6 format (105 mm × 148 mm).

All versions contain 48 pages with the most important and most fundamental information about the tolerance indications of the GPS system and how they are used to express tolerancing clearly and unequivocally in an engineering drawing.

The GPS Pocket Book is designed to be the daily reference for GPS practitioners. It helps you recall all the concepts and basic principles involved in GPS.

It can be difficult to remember the meaning of all the GPS symbols:

  • Which ones require reference to a datum?

  • Is the value in the tolerance frame the full width of the tolerance zone, or is it +/-?

  • What does the framed dimension mean?

It is all there in the GPS Pocket Book.

The GPS Pocket Book is not intended to be a substitute for all the GPS standards. Nor does it eliminate the need for GPS training. It is intended as a memory aid for everybody who comes into contact with GPS drawings:

  • Designers

  • Detailers

  • CAD Operators

  • Manufacturing Engineers

  • Quality Engineers

  • CMM Operators

  • Inspectors

  • Metrologists

The GPS Pocket Book is available in English, Chinese (Mandarin), German and Swedish.

The translators are all ISO TC 213 participants so they know the GPS system very well. This ensures that the translations use the proper standard terminology so misunderstandings are avoided. You can meet the translators at the About Us page.

The GPS Pocket Books are  set up such that each figure is on the same place on the same page in all versions and the corresponding text is also in the same place. This simplifies phone conversations with customers and suppliers across language barriers greatly, because "the picture at the top of page 15" is the same in all versions. So the buyer in Germany can use the German version of the pocket book when he talk to his supplier in China who has the Chinese version and they can discuss the same figures.

From the Foreword:

The GPS Pocket Book gives a brief presentation of the most important and the most frequently used tolerance symbols in GPS tolerancing.

The GPS Pocket Book also presents the most common rules and the most basic grammar related to the GPS symbol language. The GPS Pocket Book is not intended for stand alone use. It does not give a complete and exhaustive presentation of GPS. The purpose of the GPS Pocket Book is to be a memory aid for people who are using GPS in their daily work.

The GPS Pocket Book is intended for use together with the numerous GPS standards issued by ISO.

Only very few of the more than one hundred GPS standards are referenced and mentioned in the text. The fact that a standard is mentioned does not mean that it is the most important, only that it is the most obvious place to look for that particular issue.

Standards not yet issued by ISO on the original issue date of the pocket book (2014) are marked with the symbol, ¤, before the designation.

The GPS Pocketbook is available in English from Amazon and in Chinese, German and Swedish from our store for US$19, €17, 195 SEK or 128 DKK per copy plus applicable taxes, such as VAT, and actual shipping cost. For educational institutions buying in bulk, student copies can be bought at a 25% discount.
