HOKLAS is an accreditation scheme operated by Hong Kong Accreditation Service (HKAS). The scheme is open to voluntary participation from any Hong Kong laboratory, proficiency testing provider, reference material producer that performs objective testing and calibration, provision of proficiency test and production of reference material falling within the scope of the Scheme and meets the HOKLAS criteria of competence.For non-medical testing and calibration laboratories

For proficiency testing providers
HKAS Accreditation Criteria for proficiency testing providers are in accordance with ISO/IEC 17043:2010 "Conformity assessment - General requirements for proficiency testing". The Standard ISO/IEC 17043 contains both technical requirements and management requirements.
Clauses 4 and 5 of the Standard are reproduced verbatim in HOKLAS 017 which also includes the HOKLAS policies on application of the requirements. Proficiency Testing Providers interested in seeking our accreditation may contact HKAS Executive to obtain a copy of this document.

For reference material producers
In the first phase of this programme, it will cover chemical reference materials, both certified and non-certified. As the need arises, the programme may be extended to cover other types of reference materials.
The accreditation criteria is given in HOKLAS 022 Technical Criteria for the Accreditation of Reference Material Producers. The main text of this document is a verbatim reproduction of ISO Guide 34:2009. In addition, HOKLAS policies on individual elements are given in this document. Reference Material Producers interested in seeking our accreditation may contact HKAS Executive to obtain a copy of this document.

Accreditation Regulations Specific to HOKLAS - Reference Material Producers are given in HOKLAS Supplementary Criteria No. 39. This document is available from our website.
Accreditation is recognition of the capability of a laboratory, proficiency testing provider, reference material producer to perform specific activities and does not guarantee individual results or equate with product certification. Organisations accredited or seeking accreditation under HOKLAS are required to have their testing and measuring equipment regularly calibrated by a competent calibration organisation to obtain measurement traceability to the International System of Units (SI). The Standards and Calibration Laboratory - The Government of the Hong Kong Special Administrative Region has been designated by HOKLAS as one of such competent calibration organisations capable of providing the necessary measurement traceability.
HKAS accreditation services are classified in accordance with test categories, test areas and reference materials. Accreditation services currently available are detailed below:
HKAS will provide new accreditation service from time to time. For details of tests and calibration and reference materials covered, please contact the respective accreditation officer.
HKAS also provides accreditation service to support Hong Kong laboratories to participate in overseas testing and certification programs. Currently, such supporting service is available for the following:
For more details, please check the above titles.
HKAS coordinates proficiency testing (PT) programmes covering different test categories. Accredited and applicant laboratories may be invited to participate in these proficiency testing programmes. Interested parties may contact Mr YC Chau at 2829 4804 for details.

Asia Pacific Laboratory Accreditation Cooperation (APLAC) provides a series of proficiency testing programmes. HKAS, being a full member of APLAC, regularly coordinates proficiency testing (PT) programs under the auspice of APLAC. Please refer to publication APLAC PT003 under the respective APLAC website for more information on PT providers.
Other proficiency testing programmes
Information on other proficiency testing programmes are also available on the database maintained by the European information system on proficiency testing schemes (EPTIS). Laboratories are recommended to check with the relevant PT providers on their accreditation status before participation.
An organisation interested in joining the HOKLAS scheme should contact the HKAS Executive to obtain the necessary documents. The accreditation process is detailed in our website "Obtain Accreditation".
HOKLAS accreditation is granted for specific activities. An accredited organisation is allowed to issue HOKLAS endorsed reports/certificates only for tests and calibrations and reference materials which it is accredited. The organisation may carry out other activities for which it does not hold HOKLAS accreditation, but if it wishes to include the results of such activities on a HOKLAS endorsed report/certificate, approval from the HKAS Executive must be obtained. Such activities will have to be clearly marked as non-accredited.
Users of HOKLAS accredited service or reference materials should note that because accreditation of organisation for an individual test, calibration, reference material, or a range of tests or calibrations, may be granted, modified or withdrawn at any time, it is important to insist on that the results be reported in certificates or reports which are HOKLAS endorsed. If there is any doubt please check the current status of an accreditation with the HKAS Executive. Alternatively, the up-to-date accreditation status of a laboratory, proficiency testing provider or reference material producer can be found at "Accredited Category"
A HOKLAS endorsed report/certificate should contain the information shown below:
It is the responsibility of the user to specify test methods, where necessary, after discussion with the accredited organisation. HOKLAS does not dictate tests or rule on relative merits of test methods.
Specific recommendations for calibration and recalibration of selected items of equipment required by laboratories operating in the test categories for which HOKLAS accreditation are given in HOKLAS Supplementary Criteria No. 2. Where traceability to the International System of Units (SI) is required, the calibration is to be performed by a "competent calibration body"
