TMV2 APPROVAL

TMV2 Audit Scheme Issue 0: May 2003 

A `primary` TMV2 approval by the TAP Committee on behalf of the BuildCert Committee will be granted a `Licence` for a period of 5 years.  Additional variants and factored brands are licensed for the remaining period of the original license.

1.      Scope of audit tests 

All Primary and factored products shall be audited twice to ensure compliance with BS EN 1111 or and 1287 as appropriate, clauses 10.7, 10.8 and 10.9 within the `Licence` period (see notes below).

a)     `Master` valve receives the primary certificate.

b)      Primary certificate is issued for 5 years until licence renewal applied for.

c)     All other valves based on `Master` are limited to the same licence period as the `Master`;

d)     All valves master or otherwise undergo ancillary audits – 2no. in 5 years (dependant on remaining master valve issue life).

e)     Installation & Maintenance manual assessed for compliance.

f)       Factored valves are to be audited to ensure: -

i.        Conformity with master valve.

ii.       Complies to the requirements of BS EN 1111 and or 1287 as appropriate.

2.      Selection of TMV’s for auditing

Three valves shall be selected at random by an independent body from the manufacturer’s or the factor’s in-house off the shelf stock.

Licensee will then be notified of intention to audit and points of contact shall be agreed.

3.      Audit tests

The following tests will constitute the audit of an approved TMV: -

a)      No unauthorised design changes

b)      WRAS compliance

c)      Performance tests from section 10 of BS EN 1111 and or 1287 Clauses 10.7, 10.8 and 10.9 will be undertaken on one valve only, chosen at random from the three collected valves: - 

i.    10.7 Test for safety with cold water failure

ii.   10.8 Test for temperature stability with changing inlet pressure

iii.   10.9 Test for temperature stability with changing inlet temperature

d)      Designation – unique identification

e)      Marking

The cost for audit tests are spread over 5 years and invoiced at the same time as the annual Scheme membership fee.

The pass/fail result of all audit tests will be submitted to the TAP Committee with copies to the Licensee.

The Test House shall retain all audited valves.  Where the audit on the first valve is successful, the remaining two valves will be released by the Test House for collection by the Licensee.

4.      Failure of an audit test

If a valve fails any audit performance test.

a)   The test house will inform the licensee immediately, who will have the option to request one retest within 10 working days of receiving the failure notification.

b)   i.    If this valve subsequently passes the retest, then the valve will be deemed to comply with BS EN 1111 and or 1287 and the results will be submitted to the TAP Committee for approval.

b)   ii.   If the same valve subsequently fails the retest, then the test house will inform simultaneously the Licensee, the TAP Committee and the BuildCert Advisory Committee of the non-conformity, using, using the standard audit report form.

c)   A period of 6 weeks will then be allowed for a response from the Licensee of his assessment of the valve failure and an expression of intention.  If the Licensee does not respond within the time then the full Audit will continue automatically using the other two valves already held by the Test House (at additional cost).

d)   The Licensee may decide, after consideration, that the failure was an isolated incident in which case he can instruct the test house to undertake the full Audit using the remaining valve held by the Test House (at additional cost).

e)   Alternatively, the Licensee will provide a written assessment to TAP, which includes a description of the fault, their remedy to overcome it, the timescale to solve the problem and its effect on, and their intentions concerning the existing population of affected products.

If the TAP Committee disagree with the proposals the manufacturer will be notified and given the opportunity to provide an alternative proposal.

f)        If the TAP Committee rejects the proposal from the manufacturer, then the manufacturer will be informed and the Audit will continue automatically using the other two valves already held by the Test House.

g)   If the TAP Committee accepts the proposal (original or final) from the manufacturer, then the manufacturer will be informed and be required to provide a further random sample from new stock.  The standard audit test will then be undertaken.

h)   If the two additional valves (or the re-submitted valve, where accepted by TAP) satisfy all of the requirements then the product will be deemed to comply with BS EN 1111 and or 1287.  All interested parties shall be informed of the successful audit of valve previously advised as non-conforming.

i)        Should either of the two additional valves (or the re-submitted valve, where accepted by TAP) fail the tests, then the product shall be required to be re-tested to the full BS EN 1111 and or 1287 specification.

j)    The manufacturer may chose to withdraw the product, in which case the BuildCert Advisory Committee and the TAP Committee is informed immediately.

5.      Notification of Result

a)   Pass: The Licensee will be notified formally that his valve has passed the audit.

b)   Fail: The Licensee will be notified formally in writing with a `Warning Notice`, that his valve has failed the audit and the Licensee suspended.

The Licensee will be requested to acknowledge, in writing his intention 

i.        To submit his valve for full BS EN 1111 and or 1287 testing, or

ii.       Not to submit, in which case, the `Licence` will be withdrawn immediately.

6.      Retesting

The valve will be testing fully to BS EN 1111 and or 1287; within 3 months of the date of the `Warning Notice` the valve must comply fully with the requirements of BS EN 1111 and or 1287.
