玻璃棉岩棉等保溫材料出口澳大利亞需滿足AS/NZS 4859.1的標準要求,產品經過測試合格並經過嚴格的工廠評估後,即可頒發Standard Mark認證證書。AS/NZS 4859.1:2018新標準有哪些變化?更新了導熱值(R值)的計算和聲明方式。更多關於澳標AS4589.1認證,請諮詢南京睿督公司,諮詢電話:+86 25-86583475。
◆ 澳標AS/NZS 4859.1:2018
AS/NZS 4859.1:2018 Materials for the thermal insulation of buildings - General criteria and technical provisions
AS/NZS 4859.1:2018 標準概述了建築物隔熱材料的一般標準和技術規定。
單個材料或絕緣類型的具體要求:
(1) 硬質泡沫聚氨酯(RC/PUR)-AS 1366.1;
(2) 硬質多孔聚異氰尿酸鹽(RC/PIR)-AS 1366.2;
(3) 硬質泡沫聚苯乙烯模塑(RC/PS-M)-AS 1366.3;
(4) 硬質多孔擠塑聚苯乙烯(RC/PS-E)-AS 1366.4;
(5) 脲醛泡沫保溫原位凝固泡沫-AS 4073。
(a) Rigid cellular polyurethane (RC/PUR) - AS 1366.1;
(b) Rigid cellular polyisocyanurate (RC/PIR) - AS 1366.2;
(c) Rigid cellular polystyrene Moulded (RC/PS-M) - AS 1366.3;
(d) Rigid cellular polystyrene Extruded (RC/PS-E) - AS 1366.4; and
(e) Urea-formaldehyde foam thermal insulationIn situ set foam - AS 4073.
The scope of this Standard does not cover requirements for fire performance
◆ AS/NZS 4859.1:2018新標準有哪些變化?
更新了導熱值(R值)的計算和聲明方式。修訂後的標準AS/NZS 4859.1:2018的大變化與熱試驗和性能標籤的正式聲明有關:熱測試:對於根據本標準評估的每種材料,需要對至少10個測試結果進行統計評估。該統計評估應根據統計調整的平均值確定測試產品的R值和導熱係數,該平均值代表50%的分位數,單側公差區間的置信度為90%。表示為R50/90或λ50/90。相同的統計評估適用於所有絕緣材料,真空絕緣板除外。
◆ How is it Changing AS/NZS 4859.1:2018?
√ A statistical assessment of at least 10 test results is required for each material assessed under the standard.
√ This statistical assessment shall determine the R-value and thermal conductivity for the products tested from the statistically adjusted mean values representing a 50% fractile with 90% confidence for a one-sided tolerance interval. To be expressed as R50/90 or λ50/90.
√ The same statistical assessment is applicable for all insulation materials, except for vacuum insulation panels.
