7. Sampling and sample preparation

7.1 General requirements for taking samples (Chapter 3)

• 3.1 The sample required for determining all quality indicators must be taken in the amount specified in the national standard, industry standard or technical specification for that product; the sample required for rechecking one or several quality indicators shall be taken according to the amount sufficient for analyzing those indicators.
• 3.2 Sampling tools and containers must be clean; before sampling they shall be washed with gasoline and used after drying.
• 3.3 The samples required for blending into a composite sample may be taken with the same sampler or drill, and it is not necessary to wash it before each placement into the petroleum product; after use, the tools and containers must be washed clean with gasoline, air-dried, and stored properly.

7.2 Taking samples of paste-like petroleum products from containers (Chapter 4)

• 4.1 Small containers (large drums, wooden boxes, barrel-shaped drums, tinplate buckets or iron boxes) shall be sampled according to 2% of the total number of pieces (not less than two pieces), and equal volumes shall be blended into one composite sample; for lubricating grease supplied to special users in containers, the composite sample shall be taken according to 5% of the total number of large drums, wooden boxes or barrel-shaped drums carried by each vehicle.
• 4.2 Stand the container upright so that the top or lid faces upward, and wipe it clean with a rag; remove the top cover or lid, place it aside with the inner surface facing upward; scrape off from the grease surface a grease layer with a diameter up to 200 mm and a thickness of about 5 mm.
• 4.3 Take the sample with a spiral drill or piston-type perforator:
  • Spiral drill: screw it into the grease, pass through the entire grease layer to the bottom of the container, take out the drill, and take out the grease with a small shovel; when sampling from a large drum or wooden box, first discard 5 mm of the grease layer from the lower end of the drill.
  • Piston-type perforator: insert it into the grease through the entire grease layer to the bottom, rotate 180° so that the metal wire at the lower opening cuts off the sample, take out the perforator, and extrude the sample with the piston; when sampling from a large drum or wooden box, the grease layer of 5 mm at the lower end of the perforator shall be discarded.
• 4.4 Take equal amounts of sample from all containers, place them in a clean, dry container, and stir uniformly with a small shovel or rod (do not melt).
• 4.5 After the sample is taken out, tinplate buckets, iron boxes and wooden boxes shall be covered with lids, and large drums and barrel-shaped drums shall have their top covers put back on.

7.3 Taking samples of fusible solid petroleum products from containers (Chapter 5)

• 5.1 Sample according to 2% of the total number of large drums, wooden boxes or bags (not less than two pieces), and prepare one composite sample with approximately equal volumes.
• 5.2 Large drums: stand upright so that the top cover faces upward, wipe clean, carefully remove the top cover, place it beside the drum with the inner surface facing upward; scrape off from the petroleum product surface a layer with a diameter up to 200 mm and a thickness of about 10 mm, and cut out a sample weighing about 1 kg with a red-hot knife. Wooden boxes: place so that the lid faces upward, wipe clean, and remove the lid. Bagged: open the bag. Take out one sample from each box or bag.
• 5.3 From the upper, middle and lower parts of each sample, cut out three small sample pieces of approximately equal volume.
• 5.4 Place the small sample pieces into a clean, dry container, send to the laboratory for melting, stir uniformly, and pour into an iron mold.

7.4 Taking samples of powdered petroleum products from packaging (Chapter 6)

• 6.1 Sample according to 2% of the total number of bags or 1% of the total number of small packages (not less than two bags or two packages), and blend equal volumes into one composite sample.
• 6.2 Insert the perforator into the petroleum product and pass through the entire powder layer; then plug the opening in the bag or package.
• 6.3 Place the sample taken into a clean, dry container and stir uniformly.

7.5 Taking samples from bulk non-fusible solid petroleum products (Chapter 7)

• 7.1 When stored in piles or during loading and unloading, sample with a shovel and blend approximately equal amounts into one composite sample:
  • 7.1.1 During mechanical conveying, sample according to 20% of the number of hoppers fed;
  • 7.1.2 During vehicle transport, sample according to 10% of the number of vehicles;
  • 7.1.3 During handcart or shoulder-pole transport, sample according to 2% of the number of carts or loads.
• It is not permitted to arbitrarily select a few pieces of solid petroleum product by hand as the sample; lumps visually larger than 250 mm cannot be used as samples.
• Place the sample taken into a box, stir uniformly, and cover with a lid.
• 7.2 The sample shall be crushed within 24 h into small pieces not larger than 25 mm; place on an iron plate and carefully stir uniformly, spread into a square uniform layer, divide along the diagonals into four triangles, remove the sample from any two opposite triangles, mix the remaining sample, crush again into small pieces of 5–10 mm, and stir uniformly. Repeat the quartering method until the sample mass reaches 2–3 kg. Crushing and quartering shall be carried out in a place where dust and rain or snow are not likely to enter.

7.6 Taking samples from bulk fusible solid petroleum products (Chapter 8)

• From a batch of product, select some lumps of the same size from different positions as samples.
• For mold-cast petroleum products, the number of pieces sampled from every 100 pieces shall not be less than ten pieces.
• For petroleum products not mold-cast, take one sample per ton, but the number of pieces taken shall not be less than ten pieces.
• From different parts of each sample, cut three small sample pieces of approximately equal volume.
• Place the sample into a container, send to the laboratory for melting, stir uniformly, and pour into an iron mold.
