In this Regulation, unless the context otherwise requires-
"Accredited Laboratory" (認可實驗所) means a laboratory accredited by HKAS managed by the Innovation and Technology Commission or by a body which has a mutual recognition agreement with HKAS Executive;
"approved" (核准) means approved under section 4;
"competent examiner" (合資格檢驗師) means a registered professional engineer in the building services, gas, chemical, environmental, marine and naval architecture or mechanical disciplines under the Engineers Registration Ordinance (Cap 409);
"drum" (滾筒) means the rotating cylinder or wheel of a dry-cleaning machine that holds the materials being cleaned;
"dry-cleaning laundry" (乾洗場) means any premises in which is installed (and howsoever it is installed) a dry-cleaning machine;
"dry-cleaning machine" (乾洗機) means a machine which uses perchloroethylene to remove soil, grease or paint or other unwanted substances from materials;
"drying cycle" (乾衣程序) means the process which-
(a) is used to remove perchloroethylene remaining in the materials being dry-cleaned after washing and extraction in a dry-cleaning machine;
(b) starts with a heated portion followed by the activation of the vapour recovery system; and
(c) ends when the drum of the machine ceases rotation;
"existing machine" (現存乾洗機) means a dry-cleaning machine which is in Hong Kong before the commencement of this Regulation;
"fugitive control system" (逃逸性控制系統) means a device that collects perchloroethylene vapours from the door, button and lint traps, still, or other intentional openings of a dry-cleaning machine and routes those vapours to a device that reduces the mass of perchloroethylene prior to exhaust of the vapour to the ambient air;
"HKAS" (香港認可處) has the same meaning as it has in Regulations for Laboratory Accreditation (HOKLAS 002) of the Hong Kong Laboratory Accreditation Scheme under the charge of the Commissioner for Innovation and Technology on behalf of the Government;
"HKAS Executive" (香港認可處執行人員) has the same meaning as it has in Regulations for Laboratory Accreditation (HOKLAS 002) of the Hong Kong Laboratory Accreditation Scheme under the charge of the Commissioner for Innovation and Technology on behalf of the Government;
"HOKLAS" (香港實驗所認可計劃) has the same meaning and objectives as it has in Regulations for Laboratory Accreditation (HOKLAS 002) of the Hong Kong Laboratory Accreditation Scheme under the charge of the Commissioner for Innovation and Technology on behalf of the Government;
"lease" (出租) includes-
(a) offer or expose for lease;
(b) lease without payment; and
(c) offer or expose for lease without payment;
"materials" (物料) means wearing apparel, draperies, linens, fabrics, textiles, rugs, leather and other substances that are dry-cleaned;
"mutual recognition agreement" (相互承認協議) means any agreement or arrangement whereby the parties thereto have agreed or arranged to provide for the mutual recognition of testing laboratories which are accredited under the laboratory accreditation system administered by such parties;
"non-vented type" (密封型) means the type of dry-cleaning machine-
(a) in which the processes of washing, extraction and drying cycle are all performed in the same single unit;
(b) which recirculates perchloroethylene-laden vapour through a vapour recovery system with no exhaust to the ambient air during the drying cycle; and
(c) in which the vapour may only be vented to the ambient air-
(i) through a fugitive control system after the drying cycle is complete; and
(ii) when the machine's door is open;
"perchloroethylene" (全氯乙烯) means the substance with the chemical formula C2CI4 and also known as tetrachloroethylene;
"refrigerated condenser" (冷凝器) means a closed loop vapour recovery device in which perchloroethylene-laden vapour is cooled and condensed by means of refrigeration;
"sell" (出售) includes-
(a) offer or expose for sale;
(b) supply without payment; and
(c) offer or expose for supply without payment;
"specified period" (指明期間), in relation to an existing machine-
(a) which is a vented type dry-cleaning machine, means the period of 5 years immediately following the commencement of this Regulation; and
(b) which is a non-vented type dry-cleaning machine, means the period of 7 years immediately following the commencement of this Regulation;
"use" (使用) includes operate;
"vapour adsorber" (汽體吸附器) means a device covered with a layer of activated carbon or other adsorbent into which perchloroethylene-laden vapour is introduced and trapped for subsequent desorption;
"vapour recovery system" (汽體回收系統) means a perchloroethylene vapour recovery system which reduces the perchloroethylene concentration in the drum of a dry-cleaning machine through the recovery of the perchloroethylene vapour in a totally enclosed system by-
(a) both a refrigerated condenser and a vapour adsorber; or
(b) a means which is equivalent to the means specified in paragraph (a);
"vented type" (非密封型) means the type of dry-cleaning machine in which-
(a) fresh air is introduced into the drum during the drying cycle; and
(b) the perchloroethylene-laden vapour is exhausted to the ambient air, either directly or through a control device.
