Mechanical Test Requirements

The regulators specification consists of a series of 203 test code sheets. For an individual water fitting or  assemblies of fittings, a number of test code sheets are likely to be applicable.

To search the regulators specification click here -  Regulators' Specification Search

You can use our search to look for common fittings or assemblies of fittings or go straight to an individual test code sheet. We have listed useful search terms under three headings below:

  • Section 1 -  lists types of individual fittings you can search on
  • Section 2 – lists assemblies of fittings that you can search on
  • Section 3 – lists the names of all 203 test code sheets that you can search on

Please note that theses are generic/typical fittings and assemblies, your product may contain additional components that may require additional tests. You should seek advice from your test laboratory about the test code sheets that apply to your product.

Section 1 - Individual Fittings

Section 2 - Assemblies of Fittings (NB. Additional to tests to fittings comprising assembly)
