Isang Paunang Salita
ISO (International Organization para sa Standardisasyon) ay isang pandaigdigang alyansa ng mga pambansang pamantayan katawan (Mga katawan ng miyembro ng ISO). Ang pagbuo ng mga internasyonal na pamantayan ay karaniwang isinasagawa sa pamamagitan ng ISO teknikal na komite. Ang bawat institusyon ng miyembro na interesado sa isang paksa kung saan ang isang teknikal na komite ay itinatag ay may karapatang kumatawan sa komite. Ang pamahalaan at mga di pampamahalaang internasyonal na organisasyon na nakikipag ugnayan sa mga organisasyon ng standardization ay kasangkot din sa gawaing ito. ISO ay gumagana nang malapit sa International Electrotechnical Commission (IEC) sa lahat ng bagay ng electrical standardization.

International standards are drafted according to the rules given in Part 2 ng Direktiba ng ISO / IEC.

Ang pangunahing tungkulin ng komite ng teknikal ay upang bumuo ng mga internasyonal na pamantayan. Draft international standards adopted by the Technical Committee will be circulated to member bodies for voting. Ang paglalathala bilang isang internasyonal na pamantayan ay nangangailangan ng pag apruba ng hindi bababa sa 75% ng mga miyembrong institusyon.

ISO 15181-1-2007 “Determination of the release rate of biotoxins in paints and varnishes antifouling paints – Bahagi 1: General method for extraction of biotoxins”

Ang ikalawang edisyon ay kinakansela at pinalitan ang unang edisyon (ISO 15181-1:2000), which is technically revised, in particular by extending the use of common extraction methods to later parts of ISO 15181.

ISO 15181 binubuo ng mga sumusunod na bahagi, under the general title Paints and varnishes – Determination of fungicide release rates in antifouling coatings:

— Bahagi 1: General method of extracting fungicides

— Bahagi 2: Determination of the concentration of copper ions in extracts and calculation of the release rate

— Bahagi 3: Calculation of the rate of zinc ethylene-bis (dithiocarbamate) (zineb) release by measuring the concentration of ethourea in the extract

— Bahagi 4: Determination of concentration of pyridine-triphenylborane (PTPB) in extracts and calculation of release rate

— Bahagi 5: Calculating the release rates of toluenflurane and dichlorofluoraniline by determining the concentrations of dimethyltoluenesulfonamide (DMST) and dimethyltoluenesulfonamide (DMSA) in the extracts

ISO 15181-1-2007 “Determination of the release rate of biotoxins in paints and varnishes antifouling paints – Bahagi 1: General method for extraction of biotoxins”

Panimula
By using standard conditions for temperature, salinity and pH at low fungicide concentrations in ambient artificial seawater, reproducible values for release rates under specified laboratory conditions can be determined using the method given in this part of ISO 15181, which can be used for quality assurance and material selection purposes. Gayunpaman, the actual rate of release of fungicides from hull antifouling paints into the environment will depend on many factors, such as vessel operating schedules, years of service, berthing conditions, paint condition, as well as temperature, salinity, pH, pollutants and biota in a particular area.

The results of this test do not reflect the environmental fungicide release rate of antifouling products and are not suitable for direct use in the process of generating environmental risk assessments, generating environmental load estimates, or establishing release rate limits for regulatory purposes. When compared with copper and organotin release rates obtained by direct or indirect measurements of hull copper release rates and measurements on panels exposed in ports, all available data indicate that the results obtained using this general test method substantially overestimate the release rate of fungicides under service conditions. Published results show that for several commercial antifouling coatings, the results of this test method are generally about 10 times or more higher than direct in situ measurements of in-service hull copper and organotin release rates [1,2]. Similar relationships are expected to be found for other fungicides. A realistic estimate of the rate of hull fungicide release under service conditions can only be obtained from this test method if this difference is taken into account.

ISO 15181-1-2007 “Determination of the release rate of biotoxins in paints and varnishes antifouling paints – Bahagi 1: General method for extraction of biotoxins”

If the results of this testing method are used to generate environmental risk assessments, to produce environmental load estimates, or for regulatory purposes, it is highly recommended to consider the relationship between laboratory release rates and actual environmental inputs in order to more accurately estimate the fungicides release rates of antifouling coatings under real conditions. This can be achieved by applying appropriate correction coefficients [2].

1 Saklaw
Ang bahaging ito ng ISO 15181 specifies a general method for the extraction of biocides from antifouling paint films into artificial seawater under specified laboratory conditions. It is used in conjunction with other parts of ISO 15181 to determine the amount of specific fungicides in extracts, for example copper and/or certain organic fungicides, and to be able to calculate the rate of release of these fungicides from paint films under specified laboratory conditions.
