Vetter Pipe and Test Sealing Bags - Manual (Page 15)

Page 15/33
The function test of the pipe and test sealing bag at the maximum
operating pressure in the permitted maximum pipe diameter
must only be carried out in a resistive pipe. A pipe which is too
weak will explode when a bag is inflated to the maximum opera-
ting pressure!
When? What? What is to be done? Who?
Before each
use
Pipe and test sealing bags
along with controllers and
inflation hoses
(Safety equipment)
check for completeness
Visual check of the pipe and test sealing bags plus the
safety equipment (e.g., changes in form, cracks, fabric
damage, porous surfaces, etc.)
Function check of the safety equipment
Expert*
If there are any doubts after the visual check of the pipe
and test sealing bags regarding their safety, the bags
should be returned to the manufacturer for an in-depth
function test.

If any kind of doubts concerning the safety arise during the visual
check or function check, abort the test and send the bag inclu-

* An expert is a person who, based on his technical training and
experience, has sufficient knowledge in the sector of pipe-sealing
devices and is so familiar with the relevant governmental occu-
pational safety regulations, accident prevention regulations and
generally accepted laws of engineering (e.g., BG rules, DIN and EN
standards, technical rules from other EU member states or other
contracting states of the Treaty on the European Economic Area)
that he can assess the safe working condition of the pipe-sealing
devices. Source: BGI 802
