What does Regulation 7 ask for?
As per the Approved Document - Regulation 7:
The regulation 7 also explains ways in which workmanship can be demonstrated and Plumis uses a combination of some of these methods:
1. CE Marking under the Construction Products Directive
Under the CPR, CE marking is only required when:
• The construction product is intended to be permanently incorporated into a building or civil engineering works, and
• Where there is an applicable harmonised European Standard (hEN).
Given Automist systems are intended to be permanently incorporated into buildings, it is CE Marked under the CPR.
Several BS EN standard apply to Automist as a result of EU directives, such as the Low Voltage Directive, these have been tested by a UKAS lab and are listed as part of our Declaration of Conformity.
Download our Declaration of Conformity below.
It is important to note that BS 8458 is not a harmonised European Standard and therefore is not part of the scope of CE Marking.
2. CE Marking under other EU directives and regulations
Not applicable as per above.
3. British Standards
Automist is outside of the scope of BS 8458 because this standard is only applicable to wet pipe, ceiling mounted watermist systems. Automist is, instead, a pre-engineered, dry-pipe, wall mounted watermist system. However, BS 8458 still contains clauses (6.0 Performance) relevant to all watermist systems to demonstrate its performance and whether it is suitable for its intended use. This is why Automist has been tested and demonstrated to meet the performance requirements of BS 8458:2015.
Regulation 7 1.13 states that 'where a construction product has been made and assessed in accordance with one or more British Standards referred to in 1.11 and 1.12, this may show whether the product is suitable for its intended use.'
4. Other national or international technical specifications
5. Independent Certification Schemes
There are currently no certified residential watermist systems in the UK. LPS 1285 is still in draft form.
6. Tests and Calculations
Plumis has carried extensive fire testing in realistic domestic scenarios to validate its performance beyond the standardised tests. This can be seen in videos such as this one in Plumis's Youtube channel.
7. Past Experience
Being an innovative system there is limited past experience with Automist activations. Furthermore, when it does activate and suppress the fire, Plumis is rarely made aware of given that is has simply fulfilled its intended purpose.
Not assumed a typical method for active suppression systems, only for passive.
